Well I hope you guys like long videos HAHA!! Some context about what is also happening here. Last year I bought a $1300 TT with the engine completely disassembled. BUT the pervious owner had bought a ton of upgrades including the rods and pistons you see in the video. There will be a complete TT series coming out as soon as the car is up and running. With the turbo and upgraded parts, we should be around 400HP... Allegedly anyway HAHA!
I bought a BRZ but can’t quit watching you and DAP. Any update on the Miata? For torque wrenches I prefer the “click” since it reminds me of cracking my knuckles or back.
Hey man, absolutely love your channel and this video in particular! Will you do a 2.0 TSI version if I drive my Mk6 GTI all the way up there from Chile and hang out for a month or two? lol
Pervious? Don't be so judgmental, Charles. Also, please consider adding time stamps to your longer videos. You can even edit them into the description after the fact and TH-cam will automatically generate chapters based on them.
I remember assembling an engine with my brother. we stopped to have lunch. after lunch we washed our hands before touching the engine again. Not so sure if we washed our hands before lunch. The engine was obviously more important to keep clean.
Lol. It only takes a couple hours to build a 1.8t from a bare block. I bet it was 4x as long having to record and edit. I've got one of mine on a stand rn. Parts will be here for the weekend (sheared the crank pulley off.. 2nd time and I had even pinned it😂) I've been running Integrated Engineering rifle drilled Tuscany rods for roughly 6 years and they've survived 2 destroyed heads and 2 destroyed blocks (crank shear). Phenominal rods! I'm downsizing the turbo for this iteration because I daily drive it and the big full frame turbos suuuuuck for daily driving a manual in mountains
i watched 58 mins of a guy mounting an engine and i didn't for a second think about anything... this was the best hour i ever spent honestly, great to find a channel where to pass time not wasted (i learned a lot)
I've built about a dozen VW engines now, and I never get bored watching someone else build one! Also good to know that my best practices match yours during assembly... Looks great, it should be a runner for sure!
@@viperfukgoogplus386 None of the VW engines I built have needed rebuilt yet, one of them is on 375,000 miles and climbing. I build them for customers along with my own projects.
Always record your rod bolt free lengths before installation, that way you can reuse them if they're not permanently stretched. Also, you can install the stretch gauge over a long box end wrench, and read the stretch directly as you tighten them.
wow, literally the perfect video for me rn, was just getting the urge to go bigger turbo on my mk4 gti lmaoo i love the synergies of life sometimes! keep it up charles!
The 1.8t was such an amazing engine, I had the 224hp BAM one in my 2004 Seat Leon Cupra R. Ran very smooth, had tons of power even at low rpm (you only needed 6th gear on the Autobahn) and it was always fun to mess with luxury car owners, that bought the smallest engine and then got smoked by a 16 year old spanish car.
My MK4 GTI just ticked over 200k miles. Bought it 6 years ago as a temp car to get me to work for $1000. It took my daughter to appointments and has never failed me. I love that car and want to rebuild it. This video came out at the perfect time
You won’t regret it. I did the same after my mk5 2.5L Jetta finally gave up after 16 years (due to my own lack of maintenance admittedly). That’s when I was determined to learn to do the stuff myself. I bought a low ish miles but a little rough mk4 GTI to commute my 70mi a day in… 3 years later I’ve done timing service, suspension refresh, and currently swapping the Ill-fated 09a tiptronic “auto-tragic” transmission to the ever reliable 02J manual 5 speed. Engine just keeps ticking and if you get a wild hair you can swap out broken and trashed interior with good stuff from the plentiful used market and make it pretty nice if I’m being honest… Now I have 3 Mk4s and all are either fixed up nice or in process 😂
Hey there Charles, always appreciate your videos. I have to say, this is your best one so far. How you take the time to carefully explain everything is to your credit. your friend, volvo snob.
Much respect. You told us the even minor details which often people forget while assembling the engine. Keep up making great videos. The car owners who come are really blessed by your great effort n attention which needed to roll there cars in next many many years.
I do not comment often. but this is an insanely good video. Great dude, great knowledge and a evem better video. I like your extra cleaning etc... THIS is real engine-building like every engine should be build
Awesome video Charles! The one hour flew by in an instant! You kept the conversation light and lively and not overly technical to bore us. I look forward to part 2 to flesh out the rest of the build and firing up that bad boy! Cheers!
Humble, engine builder here. If you're going to use the piston it self to line up the ring for gapping. It's best practices to put the oil scrapper ring on the piston, if you don't there is enough play between the piston and cylinder wall to "tilt" the ring just a little and it will make the gap out a thou or so (tight when put in parallel). Buy placing the oil scrapper ring on the piston it lets the ring land square up the ring to the bore. I have a plastic tool for this that makes its easier and faster as you're not fighting a whole piston and or rod. Love the build.
Very cool to see this! The EMD locomotive engines I work on have piston oil squirters as well - both for cooling and lubricating the piston thrust washer. The pistons in the EMD engines are a floating design so they'll rotate inside the cylinder in order to increase the piston life and prevent excessive wear in one area. Edit: as a side note, I've had to loosen the end cam cap to remove an old cam seal while doing a timing belt job - if you're fighting a seal and you can easily access the cap bolts, totally worth it to make the job easier.
I owned a MK4 2003 Jetta with this exact engine (AWP) and did the timing belt job at about 65,000 miles and replaced the water pump with the euro spec metal impeller version. For me personally it was peace of mind regardless of how good the current plastic ones are. This was a great watch - I had that car for 11 years and aside from 2 coil failures and a blown turbo I never had an issue with the engine itself. Still miss that car
One thing I did on my last engine build was I had the ring gaps checked with a torque plate on. As most builders know they use these for boring the cylinders so they're the right size, because apparently the cylinders can change up to .001" in diameter. However the circumference of the cylinder (and thus ring gap) changes by .003" for every .001" of diameter change (because C = 3.14 D), which is not insignificant.
I waited until I got out of work and got home to watch this. this was very therapeutic 😊. I'm one of those wierd people that torque EVERYTHING, including drain plugs🙃
definitely want those piston squirters good. they keep the bottom of the pistons cool for the turbo boost. And if one is leaking like that it will make the oil pressure really low. Maybe that is why it spun a bearing?
yeah that sounds non issue, sorry. even with the spring broken it would only flow a bit more than the others; oil pressure mightve dropped more through it but i dont see it as being enough to spin a bearing. im thinking either high-load and cornering at a lower than full oil level (like it had been burning oil for a little while) and starving the system that way, or literally just not changing the oil enough to the point it was diluted or degraded and drop in viscosity = drop in pressure. something had been wrong for long enough to produce this failure.
@@imakedookie yea I guess that would depend on the volume of the oil pump. That squirter seems to me to be a pretty big leak. and unfortunately they dont have a running pressure on the car. at least mine dont. they only have a low pressure switch which is a very low bar amount. So you would not know weather there was low oil pressure till it was way too late.
I rarely rarely watch videos like 30 mins or longer, but Charles, your videos no matter how long they are I can watch every second of it, and enjoy it. I actually probably learned a lot of new stuff just from this almost hour long video. Keep up the great work!
Hey Charles, here in Hellas Europe when we change the Dual mass flywheel with Single mass flywheel the flywheel comes with bolts with hex head because the triple square bolt heads are very tall and the clutch disk "grind" to them. Thanks for the very detailed video 🙂🙂
The bolts used for single mass conversions on our kits here are often the stock bolts from a MK3 affirm 1.9 TDI (AHU, etc) Obviously a ton of other applications too, but that's the one that comes to mind :) Just a good tidbit if anyone else comes across this comment :)
Can't thank you enough for putting out this video. Sure there's rebuild info on this motor already on TH-cam. But not the humble mechanic way!. I have my 04' GLI sitting waiting for my first rebuild. It's people like you that can help me achieve my rebuild goal
Did you make a parts list/ parts overview for this build? I am going to be doing this EXACT same thing on my TT and a full cost breakdown and parts list would be immensely helpful. I cannot find any full lists online and I have put together my own list but am not sure if I’m missing anything
Great video. I’ve been doing a ton of research on assembling this engine and you’ve hit every nail on the head. A thoroughly enjoyable video. Great job!!
My first new car had this. I had a 2002 Jetta with this. It was so much fun. I did not know about the 1.8T back then, because I didn't know much about German cars. I thought I would be buying a VR6 12V. However, the 1.8T was less expensive than the 12V VR6. I wanted to own something different from what my parents owned, they mostly owned Hondas and Toyotas, and that made me not like Hondas and Toyotas. I went way too fast one night and nearly went to the Darwin Awards. Side airbags saved my life. 1:52 Piston squirters are great. It has been said to be a major reason the Nissan 300ZX could endure people turning up the boost. I learned so much about cars when I read the May 1998 issue of Sport Compact Car about how to get 450HP from a 300ZXTT. 5:43 I thought if you had a damaged bearing surface, you could have the crank reground at the automotive machinist, and order undersize bearings. However, some situations leave the crank too far gone for that. 7:55 It is interesting to see thrust washers. I usually see American and Japanese engine rebuilds, and they integrate that into one of the main bearings. It makes me think about how in most American and Japanese gasoline engines, they get 3 piece oil rings, and only diesels get 2 piece oil rings. Seeing a 2 piece oil ring in the VR6 really surprised me. I just thought "Who puts diesel rings in a gasoline engine?" 8:57 Worse, some people will end breaking a main cap or damaging the block if they don't seat the caps first. 13:01 In almost all cases, the top compression ring is plated and the second compression ring is unplated. That is why the top ring is a different color. This is important for newcomers, not all engines have a different ring groove width for 1st and 2nd compression rings. 13:24 No, the reason the ring gap can't be too small is because expansion will cause the ring to close and break something. 22:86 I was always told to make sure the 1st compression ring was 180 degrees from the 2nd compression ring. 33:54 The most common 5V cylinder head in the USA. Some people have never heard of a 5V cylinder head, so I tell them to look at a cylinder head for a B5 Passat 1.8T. 34:41 Also, some bolts will require you to apply sealant. Some manufacturers have cylinder head bolts that reach the water jacket. 36:04 If you mix up used flat lifters on an OHV engine, it will end soon in disaster. People who work on OHV engines build a tray that holds the removed lifters. 38:59 I always found it weird to have a timing belt engine, combined with a timing chain. This isn't just a VW/Audi thing. Many Toyota engines would have a belt to drive the cam on one end, then a timing gear that attached the cams to each other. If figure if a company is going to use timing belts, just put a belt on everything. The upside of a timing belt is that there is no metal to lubricate, and no wear metal to end up in the oil. The downside is scheduled replacement, or belt go boom. The people who choose to design a timing belt engine should be hung by one. Nobody in my family knew what a timing belt was until 1994. It went boom on mom's 1985 Maxima and made the car not worth saving. I loved that car and hated to see it go. I guess some guys at Nissan decided that the VG engine was too unbreakable, so they had to add something stupid to it. There were too many Datsun Z cars on the road that didn't make money for the parts and service department. In order to keep those people employed, a timing belt was installed on the 1984 Nissan 300ZX. I am so glad the 2002 and later Z car got timing chains. 41:55 I prefer a click. I like the pure mechanical feel. What's funny is that I like all my stuff to have a mechanical feel, even though I would rather have EFI engines than carb engines.
you asked about the sound of the torque wrench . i just got my first digital one and i have to say i would never go back i love the sound and the adjustments are so much easier . its like a carpenter going from a hand held hammer to a nail gun lol . loved the video thanks for going into so much detail i loved it
I dont currently have a VW or Audi but do enjoy watching the channel, its really informative and I learned alot. I had no idea what setting ring gaps was so thanks alot for showing what it is and how to do it! Nothings more annoying than watching a video and having someone say make sure you do xyz but never showing how to do it.
I guess you pay someone to do your engines? That may have been entertainment but it wasn't the best guide by a long shot. There was so much 'wrong' it wasn't funny He did mention later that the rings have a 'top and bottom' face, the second ring is also secondary oil control and is a Napier design (originally on aircraft piston engines, 1930's probably) Personally I haven't been a fan of Wiseco pistons since the 1980's, they use a 'soft' high expansion alloy which requires very large piston to cylinder clearance. Mahle have a proprietary blend they developed with Porsche for forged pistons which has much lower expansion rate (so 'tighter' cylinder to piston clearance, usually close to stock cast piston ) but it is more expensive
I’ve been rebuilding a Fiat 16V 1.3 turbo diesel. 75 bhp out of the box. 111 with a remap. The top end was clogged with soot but all bores were good. Main bearings and cam bearings were as new so they have gone straight back in. Turbo core and one injector have also been replaced along with cam chain rockers and lifters. The trick is to get everything really clean. I washed the outside with engine degreaser followed by a solution of biological laundry detergent. Inside everything oily was cleaned with brake cleaner and oiled with clean oil during assembly. Piston rings were replaced because oil control rings were sooted up. Annoying because the ring gaps were fine.
I had my awp short block built locally and the cylinder head(separate shops.) They've since been sitting waiting to be assembled. I've had a hard time finding motivation to start that process and this video has helped me get that going tremendously. Thank you so much 🙏🏼
I know I'm late to this one Charles, but this was a great way of unwinding after having to work on the weekend. After this I almost feel like I spent the whole weekend fishing.
I just picked up a project MK4 GLI with the 1.8T. This is a very informational video. I'm sure I will be watching many more of your videos. Thanks Charles!
As someone with two Mk4 Jettas, I've watched this video three times... And will probably watch it again as I breakdown and rebuild the GLI... THANK YOU for this video. I'm NC if you want to help; but you already have the content so..... lol
Funny I'm not a mechanic and yet I find so satisfying to watch your work, specially on this video that you are just working on the engine of my Passat ha ha
One day I want to rebuild an engine I’m already certain I’ll choose based on what videos you’ve got, and the 1.8T would be an awesome one… Ty for the time and attention to detail that goes into stuff like this, it’s really incredible 💯
Hello, many thanks for one of your professional video about our engines. In my opinion, probably the best and comprehensive video on how to assemble an engine and with very good advice and educational explanations. You become captivated by watching the same video over and over again. In short, "Top of the line" on the web. Highly recommended.
Your videos are not just entertaining, but also very informative and thorough. Thanks! I believe you answered the questions faster than O could think of them lol.
This was a great video to watch. Now, I'm not a mechanic or even much of a car guy at all. I don't own, and don't plan to own, and VW/Audi/etc cars, and I certainly have no interest in ever rebuilding a car engine. And yet, I couldn't stop watching this. Fantastic job.
Love my 2004 AWM 1.8T with 5speed manual trans. Saving this for future. Rite now after 150k the coolant temp sensor has finally started acting sketchy. Never had a leaking issue because the person who worked on it last used high temp gasket maker so I'm gonna carefully do the same. That's a long time with no issues and no leaking from that common issue.
This gives me confidence as I prepare to build my 2013 genesis coupe 2.0t( I know, not relevant) but your videos are just so awesome!! 😎 I'm soaking up all the information available 😁
I feel like I was just allowed to see a hidden art of engine-fu that most people never get to see. Wow. Also hi to anyone else who probably got recommended this because they watch a lot of Rainman and SMA o/ XD
What's more unsatisfying than the torque wrench click is watching almost one hour of engine assembly and not getting to hear it roar to life!!! :) I like how clean and methodical you're working.
You remind me a lot about my ex-father in-law. Best believe you could have been twins. I respect him so much. He taught me a lot. What's better? He is a Master Tech on VW/Audi. When other Master Techs cant fix something, he fixes it. And he does not brag about his skills or knowledge, ever!. Just as humble as you are, and you two look exactly the same. It's so weird. I love watching your videos as it reminds me alot about him and my ex-family. If you're interested, i'd like to show you a pic so you could see the crazy resemblance. From South Africa, Peace out!
I love these in depth engine rebuild type videos. I have always wanted to rebuild an engine but have never been brave enough to try. Maybe I will build a 1.8t like this one to swap into my 944 some day lol.
In the future I plan to build my a3. I will just chuck a set of rods in but this video is a massive relief as a source of information. Thankyou for the video! Took ages I bet! Thankyou
Well played bloke. Fantastic build. I'm not at the stage where i'm keen to pull my 1.8t out of my A4, but fascinating to see the level of detail that goes into the build. Keen to see this when it's all buttoned up and running.
The "twe-hey-valve-ter-bow" oh yes many many of those here in the UK too. As you say fitted to loads of different models Audi Seat Skoda VW, and lots of after market "replacement"(upgradeable) parts avaliable. ANYHOW I'll sit down and enjoy your video thank you so much for your time and effort bringing us this vid.
When the geeza working on your car talks about what he's doing as "this may not really be necessary"..... THAT'S THE MAN TO HAVE WORKING ON YOUR CAR, STUFF....fill in the blank.
Love your video superman. I have 14 tts and 2 heads to replace and the obvious timing belts and other inspections. I have my work cut out. Thanks so much. Regards, irish man.
I wanna yank out my 383 small block in my first Gen s-10 and use this platform. Good rod's, pistons, exhaust valves, and springs. Mild cam and goal of 300 -400 whp. People say hondo but, I like German engineering better than Japan. I want reliability and some fun with good fuel mileage and this seems like goals that are realistic. I've always like Volkswagen with bug's, rabbit's, and siroccros. The diesel rabbit is my favorite. You cannot break them and if you do, you've done something you should be proud of.
Love the long video. It may not get you the quick, high views, but you can be sure that it will rise to the top of the list over the next several years for "1.8T Rebuild". You've done the VR6 video, now you need to look for a good 07K 5 cylinder to do the same.
Man this is a great video I have a 2015 passat (1.8t with 6 speed dsg) and I thought of getting a "better" car but I really love this one, plus I can get 24 8' 2x4s in it with the trunk closed. Doing an overhaul and turbo upgrade and some tuning and I think I could have a passateratti in a reasonable time frame only 120000km on it. Man, thank you for this video a real pleasure to watch great form bud.
Thank you doesn't do this comment justice! Going through this process for my TT this winter. Greatly appreciate all the videos and the sense of community you help bring to the Audi/vw world. Cheers!
I noticed you mentioned spun bearings. Every time I've assembled an engine I put two-three drops of Loc-Tite red on the back of all the bearings rods mains upper and lower. I think I'm the only person who does this. Account for it in oil clearance usually halfing bearing undersized ID is enough. If oil pressure is lost for a few moments it can save you a spun bearing.
So much knowledge and experience required to do this stuff. Awesome to watch, thank you! I had one of these Audi TT Roadsters when i was a young dude, loved the 1,8t, but a bigger turbo cant hurt :)
Well I hope you guys like long videos HAHA!!

The extra cleaning you are doing is NOT overkill. Its the mark of excellence
I remember assembling an engine with my brother. we stopped to have lunch. after lunch we washed our hands before touching the engine again.
Not so sure if we washed our hands before lunch.
The engine was obviously more important to keep clean.
I wonder if the original crankshaft will withstand the force of combustion from those pistons.
I can only imagine the time and effort that went into this video, mad respect dude.
Thanks brother
I was thinking the same thing !

Also, you can install the stretch gauge over a long box end wrench, and read the stretch directly as you tighten them.

Humble, engine builder here. If you're going to use the piston it self to line up the ring for gapping. It's best practices to put the oil scrapper ring on the piston, if you don't there is enough play between the piston and cylinder wall to "tilt" the ring just a little and it will make the gap out a thou or so (tight when put in parallel).

yeah that sounds non issue, sorry. even with the spring broken it would only flow a bit more than the others; oil pressure mightve dropped more through it but i dont see it as being enough to spin a bearing. im thinking either high-load and cornering at a lower than full oil level (like it had been burning oil for a little while) and starving the system that way, or literally just not changing the oil enough to the point it was diluted or degraded and drop in viscosity = drop in pressure. something had been wrong for long enough to produce this failure.
@@imakedookie yea I guess that would depend on the volume of the oil pump. That squirter seems to me to be a pretty big leak. and unfortunately they dont have a running pressure on the car. at least mine dont. they only have a low pressure switch which is a very low bar amount. So you would not know weather there was low oil pressure till it was way too late.
@@Mikefngarage that is a shame and a half! it would help to add a port from factory that sends a signal direct to ecu, should be standard!
I LOVE long videos from you. Your demeanor and intelligence and HUMBLENESS make you a great guy to watch and learn from.
GREAT VIDEO 1.8 T.......Awesome powerhouse
I rarely rarely watch videos like 30 mins or longer, but Charles, your videos no matter how long they are I can watch every second of it, and enjoy it. I actually probably learned a lot of new stuff just from this almost hour long video. Keep up the great work!
This was awesome can't wait to see the rest of the build!
Hey Charles, here in Hellas Europe when we change the Dual mass flywheel with Single mass flywheel the flywheel comes with bolts with hex head because the triple square bolt heads are very tall and the clutch disk "grind" to them. Thanks for the very detailed video 🙂🙂
The bolts used for single mass conversions on our kits here are often the stock bolts from a MK3 affirm 1.9 TDI (AHU, etc)
Obviously a ton of other applications too, but that's the one that comes to mind :)
Just a good tidbit if anyone else comes across this comment :)
Can't thank you enough for putting out this video. Sure there's rebuild info on this motor already on TH-cam. But not the humble mechanic way!. I have my 04' GLI sitting waiting for my first rebuild. It's people like you that can help me achieve my rebuild goal
David this comment made my day!!
Did you make a parts list/ parts overview for this build? I am going to be doing this EXACT same thing on my TT and a full cost breakdown and parts list would be immensely helpful. I cannot find any full lists online and I have put together my own list but am not sure if I’m missing anything
did you do it? you have a list?😅
Gettin' Bob Ross vibes, this is a compliment.
No happy little accidents here 😐
Great video. I’ve been doing a ton of research on assembling this engine and you’ve hit every nail on the head. A thoroughly enjoyable video. Great job!!
My first new car had this. I had a 2002 Jetta with this. It was so much fun. I did not know about the 1.8T back then, because I didn't know much about German cars. I thought I would be buying a VR6 12V. However, the 1.8T was less expensive than the 12V VR6. I wanted to own something different from what my parents owned, they mostly owned Hondas and Toyotas, and that made me not like Hondas and Toyotas.
I went way too fast one night and nearly went to the Darwin Awards. Side airbags saved my life.
1:52 Piston squirters are great. It has been said to be a major reason the Nissan 300ZX could endure people turning up the boost. I learned so much about cars when I read the May 1998 issue of Sport Compact Car about how to get 450HP from a 300ZXTT.
5:43 I thought if you had a damaged bearing surface, you could have the crank reground at the automotive machinist, and order undersize bearings. However, some situations leave the crank too far gone for that.
7:55 It is interesting to see thrust washers. I usually see American and Japanese engine rebuilds, and they integrate that into one of the main bearings. It makes me think about how in most American and Japanese gasoline engines, they get 3 piece oil rings, and only diesels get 2 piece oil rings. Seeing a 2 piece oil ring in the VR6 really surprised me. I just thought "Who puts diesel rings in a gasoline engine?"
8:57 Worse, some people will end breaking a main cap or damaging the block if they don't seat the caps first.
13:01 In almost all cases, the top compression ring is plated and the second compression ring is unplated. That is why the top ring is a different color. This is important for newcomers, not all engines have a different ring groove width for 1st and 2nd compression rings.
13:24 No, the reason the ring gap can't be too small is because expansion will cause the ring to close and break something.
22:86 I was always told to make sure the 1st compression ring was 180 degrees from the 2nd compression ring.
33:54 The most common 5V cylinder head in the USA. Some people have never heard of a 5V cylinder head, so I tell them to look at a cylinder head for a B5 Passat 1.8T.
34:41 Also, some bolts will require you to apply sealant. Some manufacturers have cylinder head bolts that reach the water jacket.
36:04 If you mix up used flat lifters on an OHV engine, it will end soon in disaster. People who work on OHV engines build a tray that holds the removed lifters.
38:59 I always found it weird to have a timing belt engine, combined with a timing chain. This isn't just a VW/Audi thing. Many Toyota engines would have a belt to drive the cam on one end, then a timing gear that attached the cams to each other. If figure if a company is going to use timing belts, just put a belt on everything. The upside of a timing belt is that there is no metal to lubricate, and no wear metal to end up in the oil. The downside is scheduled replacement, or belt go boom. The people who choose to design a timing belt engine should be hung by one. Nobody in my family knew what a timing belt was until 1994. It went boom on mom's 1985 Maxima and made the car not worth saving. I loved that car and hated to see it go. I guess some guys at Nissan decided that the VG engine was too unbreakable, so they had to add something stupid to it. There were too many Datsun Z cars on the road that didn't make money for the parts and service department. In order to keep those people employed, a timing belt was installed on the 1984 Nissan 300ZX. I am so glad the 2002 and later Z car got timing chains.
41:55 I prefer a click. I like the pure mechanical feel. What's funny is that I like all my stuff to have a mechanical feel, even though I would rather have EFI engines than carb engines.
Nice build 👌 very educational, I thoroughly enjoyed the video.
except the piston measuring and ring 'selection' was so bad it was painful to watch.
you asked about the sound of the torque wrench . i just got my first digital one and i have to say i would never go back i love the sound and the adjustments are so much easier . its like a carpenter going from a hand held hammer to a nail gun lol . loved the video thanks for going into so much detail i loved it
Badass H rods!
I dont currently have a VW or Audi but do enjoy watching the channel, its really informative and I learned alot. I had no idea what setting ring gaps was so thanks alot for showing what it is and how to do it! Nothings more annoying than watching a video and having someone say make sure you do xyz but never showing how to do it.
Love it mate thank you🙏by far the best guide on youtube👍🏻 planning on forging mine and putting a different turbo on my tt
I guess you pay someone to do your engines?
That may have been entertainment but it wasn't the best guide by a long shot.
There was so much 'wrong' it wasn't funny
He did mention later that the rings have a 'top and bottom' face, the second ring is also secondary oil control and is a Napier design (originally on aircraft piston engines, 1930's probably)
Personally I haven't been a fan of Wiseco pistons since the 1980's, they use a 'soft' high expansion alloy which requires very large piston to cylinder clearance.
Mahle have a proprietary blend they developed with Porsche for forged pistons which has much lower expansion rate (so 'tighter' cylinder to piston clearance, usually close to stock cast piston ) but it is more expensive
I’ve been rebuilding a Fiat 16V 1.3 turbo diesel. 75 bhp out of the box. 111 with a remap. The top end was clogged with soot but all bores were good. Main bearings and cam bearings were as new so they have gone straight back in.
Turbo core and one injector have also been replaced along with cam chain rockers and lifters.
The trick is to get everything really clean. I washed the outside with engine degreaser followed by a solution of biological laundry detergent.
Inside everything oily was cleaned with brake cleaner and oiled with clean oil during assembly. Piston rings were replaced because oil control rings were sooted up. Annoying because the ring gaps were fine.
I had my awp short block built locally and the cylinder head(separate shops.) They've since been sitting waiting to be assembled. I've had a hard time finding motivation to start that process and this video has helped me get that going tremendously.
Thank you so much 🙏🏼
This is how you would want any mechanic to work on your engine. Top job
This literally could not have come at a better time. My 1.8t is at the machine shop getting all fixed polished up and ready for my build.
I know I'm late to this one Charles, but this was a great way of unwinding after having to work on the weekend. After this I almost feel like I spent the whole weekend fishing.
I just picked up a project MK4 GLI with the 1.8T. This is a very informational video. I'm sure I will be watching many more of your videos. Thanks Charles!
As someone with two Mk4 Jettas, I've watched this video three times... And will probably watch it again as I breakdown and rebuild the GLI... THANK YOU for this video. I'm NC if you want to help; but you already have the content so..... lol
Funny I'm not a mechanic and yet I find so satisfying to watch your work, specially on this video that you are just working on the engine of my Passat ha ha
I have this engine on my tt and it’s probably the most reliable engine on a Audi/VW I ever had I love it and I like how high power it can make
One day I want to rebuild an engine I’m already certain I’ll choose based on what videos you’ve got, and the 1.8T would be an awesome one… Ty for the time and attention to detail that goes into stuff like this, it’s really incredible 💯
Yesss!!! I’d grab a junk yard engine, teardown and rebuild as is. It’s great practice
Hello,
many thanks for one of your professional video about our engines. In my opinion, probably the best and comprehensive video on how to assemble an engine and with very good advice and educational explanations.
You become captivated by watching the same video over and over again. In short, "Top of the line" on the web. Highly recommended.
Nice engine stand, man.
i could watch you assemble engines all day long man, flawless work!
Your videos are not just entertaining, but also very informative and thorough. Thanks! I believe you answered the questions faster than O could think of them lol.
You make it look so easy making me want to build the 1.8t that’s been in my shed for a year lol
This was a great video to watch. Now, I'm not a mechanic or even much of a car guy at all. I don't own, and don't plan to own, and VW/Audi/etc cars, and I certainly have no interest in ever rebuilding a car engine. And yet, I couldn't stop watching this. Fantastic job.
this video is awsome, as a early student on carmechanics this makes everything come to light so easy
Love my 2004 AWM 1.8T with 5speed manual trans. Saving this for future. Rite now after 150k the coolant temp sensor has finally started acting sketchy. Never had a leaking issue because the person who worked on it last used high temp gasket maker so I'm gonna carefully do the same. That's a long time with no issues and no leaking from that common issue.
This gives me confidence as I prepare to build my 2013 genesis coupe 2.0t( I know, not relevant) but your videos are just so awesome!! 😎 I'm soaking up all the information available 😁
I feel like I was just allowed to see a hidden art of engine-fu that most people never get to see. Wow. Also hi to anyone else who probably got recommended this because they watch a lot of Rainman and SMA o/ XD
What's more unsatisfying than the torque wrench click is watching almost one hour of engine assembly and not getting to hear it roar to life!!! :)
I like how clean and methodical you're working.
I know. But you’d never get this video if that was the case. :(.
I’ve learned the community needs a payoff. And they need it now 😂
You remind me a lot about my ex-father in-law.
Best believe you could have been twins. I respect him so much. He taught me a lot.
What's better? He is a Master Tech on VW/Audi. When other Master Techs cant fix something, he fixes it. And he does not brag about his skills or knowledge, ever!.
Just as humble as you are, and you two look exactly the same. It's so weird. I love watching your videos as it reminds me alot about him and my ex-family.
If you're interested, i'd like to show you a pic so you could see the crazy resemblance.
From South Africa,
Peace out!
I love the box trick with the "peggy hooks". Never seen or thought about that before!
I love these in depth engine rebuild type videos. I have always wanted to rebuild an engine but have never been brave enough to try. Maybe I will build a 1.8t like this one to swap into my 944 some day lol.
944 gang
In the future I plan to build my a3. I will just chuck a set of rods in but this video is a massive relief as a source of information. Thankyou for the video! Took ages I bet! Thankyou
Well played bloke. Fantastic build. I'm not at the stage where i'm keen to pull my 1.8t out of my A4, but fascinating to see the level of detail that goes into the build. Keen to see this when it's all buttoned up and running.
You're the best engine builder i've ever seen!
The "twe-hey-valve-ter-bow" oh yes many many of those here in the UK too. As you say fitted to loads of different models Audi Seat Skoda VW, and lots of after market "replacement"(upgradeable) parts avaliable. ANYHOW I'll sit down and enjoy your video thank you so much for your time and effort bringing us this vid.
When the geeza working on your car talks about what he's doing as "this may not really be necessary"..... THAT'S THE MAN TO HAVE WORKING ON YOUR CAR, STUFF....fill in the blank.
That thing is going to be wicked, Ive driven a stock 1.8t car and it was no slouch!
Great video for your fellow ocd mechanics. The easiest to follow video I’ve ever watched.
love it how you make it look soo easy and calming.
bob ross of engine builders
love the content brother!
the only thing i think the channel miss is you puting a playlist just working on engines
love from UK
I love this long very well explained videos! I can watch all day long. Thanks 👍🏿
Thank you
Love your video superman. I have 14 tts and 2 heads to replace and the obvious timing belts and other inspections. I have my work cut out. Thanks so much. Regards, irish man.
i have never rebuilt an engine before but watching this was great you kept it interesting and I learned so much. Thank you .
YOU ARE A VDUB WIZARD.I ONLY LISTEN TO YOUR ADVICE AND TIPS.AWESOME CONTENT
Great timing, currently rebuilding the engine for my 25th Anniversary GTI.
I wanna yank out my 383 small block in my first Gen s-10 and use this platform. Good rod's, pistons, exhaust valves, and springs. Mild cam and goal of 300 -400 whp. People say hondo but, I like German engineering better than Japan. I want reliability and some fun with good fuel mileage and this seems like goals that are realistic. I've always like Volkswagen with bug's, rabbit's, and siroccros. The diesel rabbit is my favorite. You cannot break them and if you do, you've done something you should be proud of.
Tour voice delivery makes people SICK.
Love the long video. It may not get you the quick, high views, but you can be sure that it will rise to the top of the list over the next several years for "1.8T Rebuild". You've done the VR6 video, now you need to look for a good 07K 5 cylinder to do the same.
Man this is a great video I have a 2015 passat (1.8t with 6 speed dsg) and I thought of getting a "better" car but I really love this one, plus I can get 24 8' 2x4s in it with the trunk closed. Doing an overhaul and turbo upgrade and some tuning and I think I could have a passateratti in a reasonable time frame only 120000km on it. Man, thank you for this video a real pleasure to watch great form bud.
Blew my s3 engine few days ago, probably went lean and burnt a piston, soo that video will help me alot bc it's going to be my first rebuild
Thanks!
What’s funny is I am not a fan of Volkswagens in the slightest but watching these videos makes me want to build one of these motors
Thank you doesn't do this comment justice! Going through this process for my TT this winter. Greatly appreciate all the videos and the sense of community you help bring to the Audi/vw world. Cheers!
This is absolutely perfect. I just got a free mk4 Jetta and want to rebuild the motor at 200k miles.
A true genius at work. Just loved the video. Keep up the excellent work
Transverse Engine- quite a significant pain unless out of the car.
Long - Engine so much more fun.
Good video as always brotha
Awesome, thank you for this video! I am extremely interested in more of this tt build.
I noticed you mentioned spun bearings. Every time I've assembled an engine I put two-three drops of Loc-Tite red on the back of all the bearings rods mains upper and lower. I think I'm the only person who does this. Account for it in oil clearance usually halfing bearing undersized ID is enough. If oil pressure is lost for a few moments it can save you a spun bearing.
What I learn from Charles when he posts...Always clean and lubricate :)
ALWAYS LOL
So much knowledge and experience required to do this stuff. Awesome to watch, thank you! I had one of these Audi TT Roadsters when i was a young dude, loved the 1,8t, but a bigger turbo cant hurt :)
Great video. I've watched this video multiple times and enjoy it every time. Thank you.
Also in the Seat Leon here in Europe 🇪🇸 I have 1.8t BAM in my cupra R 🇬🇧 😎👍
