What's the part number for the head gaskets?
H4017053S
Sweet vid m8 i have a L36 with a 4t65e like to put bigger cam and upgrade heads oneday. Always fun 2 do the work yourself!
When scraping the old gasket off use a shop vacuum at the same time and scape the crap right into the vacuum!
I
I know its a bit of extra effort but opening up the ring gaps on these motors really helps to stop the pistons giving up on life under boost.
Christian Stephens Have you had a bad experience in the past with end gaps?
Any boosted engine should have a 16 thousandth to 20 thousandth ring gap. If I remember correctly.
@boostedbuiltgarage I think he's embarrassed from being streched!😮
Love watching your videos, I’ll hopefully be starting my L27 build shortly. I’ve watched all of your videos some even twice lol.
Matthew Downes Awesome man! Thanks for the support, means alot!
Sorry mate this is the only place you can see it
Nice work buddy 🤙🏼 good old torquing ARP headstuds. Did that on the foz a few weeks ago, nearly rolled the engine stand hahaha
Puds Garage Hahaha damn right!
Excellent vids, well done ! Very clear and informative.
Good job mate, can't wait for next episode
Good stuff! It'll be back and better than ever in no time mate.
Keep the stuff from going I to the engine. Perhaps sand it on its side angled slightly downward or cover the pistons in lite grease to catch the sparklies
Shaving foam works great. And it leaves your engine baby-soft and lime-fresh.
Hey mate just my 2c but a better way to clean the head/block in my experience is red scotch brite and crc spray works just as good as the stone and also had no chance of gouging anything out if needing to work in a single spot
Yeah Scotch Brite is great but it's always good practice to use something flat that spreads the load over a bigger area, to not overly concentrate in one area and risk any high or low spots. For the cast iron block I doubt that'd be a problem. It also shows you where any high/low spots are using a stone.
@@boostedbuiltgarage where can I get one of these stones and what exactly are they called again
It's an aluminium oxide sharpening stone, used for honing chisels, knives etc. Any hardware store should have them
Great vid man cant wait to see some boost vids
Scotchbrite is ur friend instead of a $60 block of whatever it is. That block ur using is dangerous man! Felpro gaskets are the best.
I use a laser to clean up everything...its so much easier and no mess
Is it affordable?
Awesome videos to learn from bro keep it up cheers
awesome video mate, thinking about boosting my VR in the future for a good powerful daily
Just a little nit picking -- when using a torque wrench, it's recommended not to clasp the socket end hard and/or hold it tightly. This puts additional resistance on the socket and will give you a false reading.
i left when the oil stone came out .
Way to get after it mate!
I might of missed a video on the timing chain or that wasn’t changed for a double row ?
It already has a double row. If it's not in part one it'll be in one of the later parts. There's nothing before part 1 lol
If I have sorrento 2007 with engine 3800 ..and if I want to change it with engine of 3800 of another car what is suitable for me to have the same settings. Thanks for answering
Back so soon.👍 Keep up the good work.and I have been trying to buy sum t shirts off you but I keep getting an error can you please help me with this. 👍
John Darwen Yeah mate! No time to waste😉
Oh really? What's happening? If you want, message me on the website with what you want and I'll sort it
brass wheel congrats. I always tell people to use them
Whats the best way to clean out coolant and oil passages. Because even though i stuff em with blue shop towels ill still get crud in there from the wire wheels
Don't use any abrasives to clean the block or heads. Scrape with a razor blade and wipe with a solvent.
Unfortunately a razor Ain't gonna cut it with most head surfaces... Nor is it going to be an acceptable RA finish to work with MLS head gaskets...
pfft how many engines have you seen killed by the abrasives? you just have to clean it more and change the oil a couple of times when you carefully block sand or stone a head or deck it often enough trues it up flat again ..I've done tons this way never seen any problems ..
This motor is considered a L26 in Canada
Pretty sure the instructions say a light coat of that copper coat.
Instructions on the ARP head bolts say don't use glue or sealant, and rather a threaded tape, like a automotive plumbers tape or even just plumbers tape 🤣
What was involved to put the double row timing chain on?
very cool
If nothing else breaking the last motor is a good opportunity to make more vids. When i use mls gaskets i always re torque them a second time( unless they are torque to yeild) ive found on tractor engines you can sometimes get as much as a quarter turn out of them from the gasket squashing after a heat cycle, yours are used so probably not much squish going on there but if it was me id check a second time
Haha yeah definitely right mate. A chance to start somewhat from the beginning again with some detailed videos. Yeah that's an interesting point, I should check but honestly don't have the time/cbf to recheck cause I gotta remove valve covers, exhaust manifolds etc hahaha
Hey mate do you know if it’s possible to put a VS 5 speed gearbox on to a vr buick ?
I’m looking at buying a roll master chain to but on the mace web site there’s 2 different ones a LN3 v6 one and a L27 what do they stand for I’m confused
The LN3 is in the VN-VG. L27 is VN series 2 to VR I'm pretty sure.
Just shoot them an email, they're really good to deal with, if you give your engine number you'll make sure you have the right chain as they have a slightly different crank diameter
Boosted & Built Garage sweet to easy thank u for that
Thanx bruh..
Just on your head gasket i was watching a zzp clip & he separeted a pair of zzp multi layer steel head gaskets & he said he was going to re rivet them toghter but never showed the process.what do u think? Did he use a normal rivet ?
I un-riveted mine to clean them and recoat them last time I had my heads off and didn't bother re-riveting them. They're located by the head studs if you run them. As long as you orient them the right way of course
Are those L67 heads or standard heads that have been worked?
hi mate i know u will know this how do the lobes run on a vt vx vy v6 is it intake 1st followed by exh exh then i ntake again? got a cam thats not measuring up either ive got the order wrong or the grind is out. if u can help please. cheers!
Don't know from top of my head but will be obvious by looking at the cylinder/valve layout in the heads
Hey mate did you have any drama with torquing them down at 80ft/lbs and getting the heads outta shape and causing a leak? I've heard people dont tend to go right up to arp specs because of it.
Not that I'm aware of. No issues for me... Just follow the torque sequence, torque in several stages and have true, flat deck surfaces
80ft lbs seems high for a nut on stud. Bolts are that high, but a stud is usually a lot lower, because it's not stretching a bolt.
Did you change your camshaft? When you did your heads or you still have stock camshaft??
Nah stock cam, still seeing how far we can push the stock cam. Custom grind cam in the future for sure though
@@boostedbuiltgarage stock cam must be fairly strong!
@@boostedbuiltgarage throw balance shaft away put in cam 60 lb injectors 260 rwkw with port n pol with ls1 valve springs
that was on 12 psi
Hey dude u @ 4.40pm saturday 7th of october we both drove past each other up at the end of galston gorge hornsby side today finnaly seen ur beast bro & i was in my white vs stato 👍 im am not stalking im mearly saying we drove past & seen ur ute bro phat as 👌👍👍
Rhys Bower Hahaha I remember you actually!🤙
Lol sweet bro
old Galston Gorge hey, cut my teeth racing my 75' mini through there with my mate in his 69' Corolla, awesome bit of road/ race track ! :) If you hear of any one down Hornsby/Galston way with a VS ute for sale, let me know hey ? Born and bread in Berowra/ Hornsby in the 70's and 80's . Love your engine re-building series mate, easy to follow :)
Not going to lie some of this made me cringe.
This is what you'd have to do in the Mad Max universe.
"Just hit the deck with an oil stone"
It works. Just not pro level!
Hay m8 is it possible 2 change the cam bearings in a 3.8lt while the engine is in the car?
Yeah I'm sure it is. I haven't done it but can't see why not
hi, u know when u put the ARO haed studs in by allen key is it nesesaryto torque them in @ that stage?
No, just til they're snug. Remember, Make sure they've all got sealant on them because they're in the water jacket in the block
do u meen thread locking compound?
Somewhat. GM sell a special one, I use RTV, other people use other sealants too. Few ways, but all I can comment for is the RTV I've never had an issue and obviously the GM stuff is meant for it too
How not to build a motor.
Mate how do you know so much about motor rebuild if your a chippy ??? Steve from Bundaberg Qld 🍹🕺
Always had a passion for mechanical stuff. Just play around with things and learn. As well as knowing some knowledgeable people to bounce things off and learn from as well. 😎
@@boostedbuiltgarageCool 👍 Knowledge is NOT a burden & you matey have have it in spades 😝👍🕺
What's the thing that rotates in the valley it's running off the cam gear I think
It's a balance shaft. It's there to try balance/cancel out any harmonics or vibrations due to the angle of the 'v'
@@boostedbuiltgarage The American builders delete the balance shaft, it makes almost no difference.
balance shaft. get rid of it.
No point deleting the balance shaft unless you are going to get the rotating assembly fully balanced to suit
Well you have to delete it to run the double row timing chain. Makes no difference to the engine, is still totally smooth revving to 6500rpm without it in my setup
How would a alloytec go with boost?
jaryd t Can be done but nowhere near as strong
Hey mate just a question What else fails on them either than the timing chains? I think otherwise of the Alloytec
the block.
What yr engine
What glue did u use on your studs
Rtv
What rtv
how much boost can this engine take safely ?
Still waiting to find out what the limit is. Currently been running 20psi for a little over a year...
Hey bro where did you get the engine from
From yo mama
What kind of car is that behind the engine?
You're the only person who's ever asked after years of videos with it sitting there. It's a 1930 Cadillac V16
@@boostedbuiltgarage I've always wanted to comment an ask this but also wouldve asked if you could do a Lil video on it explaining it haha
Is that a 109 block 3.8 ?
No, it's from A 1995 and newer fwd vehicle.
U want to use cosmetics head gaskets
is the L27 identical to the L36?
Very similar but not identical, no. Especially when it comes to the heads and inlet manifold (different port spacings, 2 piece intake manifold etc
Thanks for the info man. A quick question, what is the website you bought the parts from?
im planning to mod my 2004 vy l36
If you are boosting, just grab an L32 bottom end and do a top swap. That way you have an engine built for a SC.
I never saw anything for this video.
6:20 yes take the dowels out. What is this chimp even doing? Don't stone your deck without washing the block out.
I got my crank & oil pump cryogenic treated to improve reliability. Piston tops & skirts coated in special crap from where they ceramic coat headers. www.heat.com.au/treatments-cryotemp.php
dcptiv Yeah I would be doing all those good things when I build a really good motor later - good stuff though ha!
You really shoved as much ads in as possible ay.
Well so much using a machine for making it flat.
no matter what you do ecotec commy motors just sound like poo 😂 I have a 96 s2 Vs Commodore
In NA form yeah they sound shit
Boosted & Built Garage tbh even turbo ones sound shit, l67 dont sound as bad still sound weird
Never, ever re-use head gaskets! And never, EVER touch the surface of a head gasket with your oily hands!
John Doe MLS head gaskets are reusable buddy lol.
BoostinGP technically yes, but after a few cycles of taking them off, the layers compress to a point that they can’t come back to shape from and they end up leaking
Hate when guys say "motor" over and over instead of saying engine sometimes
Well, they are called "motor" vehicles for a reason.
What else do you hate your boyfriend saying bro?
