Yay for new mike, sounds good. Bought a car once that wouldn't run right, friend of mine figured it was out of time. Took awhile to figure out the previous owner had replaced the timing chain and got that off a bit. I never really got past the part swapper stage of mechanics so that was a learning experience for me.
That's really nice.I used to use a rod down in the sparkplug hole and rock the engine around until I got pretty close, but this will get you dead on.Good thing you remembered that stop.I got a junkyard engine once with a bolt in the cylinder.Had an impression on the piston top and right between the valves.Ran it for years but that wasn't a dragster.
This is amazing, I forgot to line up my timing pointer before I put my heads on, and I was thinking I was going to have to jerryrig some long test indicator into the spark plug hole to find true tdc. Thank you for this!
I had a damper come apart, and marked the hub with a TDC mark. I always wondered how important the damper was, from a engine damage standpoint. Recently I saw a late 80's four cylinder F1 engine dev. video. They were mysteriously throwing rods, later determined all due to harmonics.
Hey thanks for the simple explanation and recording these videos. I suspect my 347 stroker pointer is off and I know my MSD Pro Digital is miles off. This will be the first step to getting it to run as it should. I did all my own work on body, interior and mechanical except the machine work and the dif setup. Now I need to learn how to tune it.
Great video buddy! I haven't seen a V8 with #1 on the right side but the 3.6L Cadillac engine's, bank 1 is on the right side, throughs you off a little bit when diagnosing missfires and you forget your looking at the wrong side lol
Hey man! Yes that did make sense.I got the new timing light.It was better than the old one. Also I checked the distributor again and it has adjustable rotor.The nuts and washers were no good and the rotor could not stay in place when revving the engine.So after replacing those I was able to set the total timing at 38 degrees.The idle was still off and I´m going to calibrate the carburetor today or tomorrow.I hope everything works after that.Thank you for your help! I should make a video too...
I would set the timing at 36 degrees with when its up on rpm so the timing is all in and after that see where your timing is at when you let it idle down. The 36 degree max is the important one
Yes all v motors i know of # 1 is most forward, but if i remember right to set ign timing on older international v 8 motors you use no. 8 CYL. Isn`t that weird. Great video
@groutaone When I got it home and installed it, I cranked it over and it stopped after half a revolution.Then I noticed a sparkplug missing.Fished around with a magnet and pulled the bolt out.Awhile afterwards I did a head gasket on it and was amazed how close the bolt came to the valves.
@Grannysteacup It could be a plugged jet, main jet sounds fine though, crank seals maybe or reeds as you say, the power as you describe does not sound far off from being normal for a 125 two stroke however
Say I thought of it today, if your distributer for some reason has way too much advace curve, say like 40 degrees or something crazy, that would make it stall when it idles down, maybe something loose or broken in the distributer?
It would be nice if you could make a video demonstrating and explaining, the reason why true TDC has to be calculated using 2 points of reference. If you check their are plentiful videos showing this procedure. However, no video explaining and demonstrating the reason and the [ piston dwell] culprit.
Hi, Great video, I see that some people just put a whistle TDC finder on spark # 1 hole and turn clockwise until the whistle stops sounding. When whistle stops, that would be their TDC at compression stroke. Is that approach as accurate as yours? Once determined TDC, for timing purposes, I should line up the distributor rotor to plug 1 and then go with the timing like, correct?
Can you offer some diagrams for people who want to front half their car eg if they were building a serious bracket car or pro mod and what are the considerations for suspension and steering and which are the best parts to use? P.S. I've been advocating that method for finding TDC for years, and it's great for motorbikes that usually dont have pointers or marks and most car balancers always seem to be slightly out, no matter the brand
I used this exact method to confirm TDC on my 388 SBC today, and I have a very similar adjustable timing pointer and a balancer that is pre-marked. The only difference between what you did and what I did, Is I had my cylinder head removed and used a piston stop attached to the block. Anyway, the TDC mark I found with this method using my two marks was about 3 degrees after top dead center passed the zero stamped on my balancer. I have a picture if you would like to see. I know I'm making this harder than it needs to be, but do I just rotate my motor around to line the zero on the balancer up with my pointer, and then adjust the pointer to the actually TDC mark I found with this method? I hope this makes sense. Thanks in advance!
Their is an engine family that has the #1 sparkplug on the cylinder bank that's recssed... And that's Pontiacengine family, my educated guess [ I my be wrong ] is that Pontiac Division wanted cylinder # 1 to be on the right bank. But, GM executives wanted all GM engines to have cylinder # 1@ the left bank. However, the engine was already designed in a manner that the left bank was recessed, to late to redesign.
Great vid, my 09 honda odyssey broke a timing belt. Ya interference engine compression shows atleast bent valves. Gona try gearwrench boltbiter sockets since heat and PB wont get header or exhaust bolts loose. Then both heads come off. Crossing fingers rebuilt heads gets me back on the road. Would luv to see your vid on TDC with heads off👍👍👍👍
Does it matter what size length bolt u use to weld onto your spark plug? Or does it not matter as long as u spin it back around then meet in the middle upon the timing wheel?
Ok which way is the most likely to slip backwards so it looks like too adv. Timing or the other way? When using a piston stop and turning motor backwards is there any chance the piston hitting the valves? Would a dial indicator work as well if not better?
I was wondering why my motor runs better too advanced. Just welded up a stop, spun the motor both ways and marked it, split the difference. My balancer mark was 6 degrees after TDC.
hi I have a 12valve 190e 1984 mercedes benz a 2.3 engine.i have difficulties in finding the exact tdc of the engine.after building up the engine.it have difficulties in starting the engine.i only use a screw driver to find the compression.do i have to rotate counter clock wise after the compression at cylinder is up, and after a 1half inch of rotation is the tdc? thanks for your very informative videos:)
Nice Ride ! So to find TDC you have to be on the compression side, right ? You got the valve cover's on and can not see the valves so how do you know for sure ?
Every other TDC the spark plug fires for #1 cyl, but that doesn't matter, TDC will still be the same because the crank throw will always be the same regardless of what the camshaft is doing. You are simply measuring the longest part of the crank throw for #1, it has nothing to do with cam components.
Shawn..Harmonic balancer are as vital as your heart...Stock balancer's are for STOCK motors NOT Hi-Po street strip . get a fluid damper or the TCI rattler as it absorbs all harmonics do not skimp or you will pay for it when your crank N rods say's see ya..
Hey man, nice to see your 20+ years of folding experience is up to some good use! Great way to simplify that procedure!

Put thid video in favorites for future 350's.
that is brilliant! Thanks for the video. It really helps new big block owners like myself.
Thank you for the video. It finally clicked for me what I was doing because every other video I found had the heads off.

I really like your Tech videos. Nice job.
Dude, all your videos rule. Thanks for putting them up.

@cudaclan I haven't work on to many fords in the past, but I will keep an eye on that if I ever work on them! Thanks for the heads up.
that is an excellent way to find TDC
awesome video very informative I just picked up a chevy bb and I'm a little fuzzy on the bb stuff will def be tuning in more often peace!!!!
@roro560v8 The only thing that happens if the stop is too long is the mark on the tape is kinda far from the middle mark
You sir are amazing, keep up the amazing videos.
That's nothing less than "AWESOME" I love your car....
You really do make a lot of interesting vid's.....
Keep up the good work....

I would set the timing at 36 degrees with when its up on rpm so the timing is all in and after that see where your timing is at when you let it idle down. The 36 degree max is the important one
Good stuff Buddy!! I never knew that about the stock Chevy HB!! The mic sounds great, what kind is it!! PM me if you don't want to advertise them!!☺
@magna59 Yep its electric, on the street it wouldnt keep up but its awesome for short compitition, its controlled by a thermostat in the water jacket
New mic sounded pretty good. My mic on my camera is too quiet. Any way, liked the video, timing is a huge deal as I found out on my Onan rebuild.
Yes all v motors i know of # 1 is most forward, but if i remember right to set ign timing on older international v 8 motors you use no. 8 CYL. Isn`t that weird. Great video
@groutaone When I got it home and installed it, I cranked it over and it stopped after half a revolution.Then I noticed a sparkplug missing.Fished around with a magnet and pulled the bolt out.Awhile afterwards I did a head gasket on it and was amazed how close the bolt came to the valves.
@fatstercat Thanks, for the most part you will find the big blocks are very much like the small blocks, they just have a little more meat on the bones
THANK YOU SO MUCH! Ill have my LTD running within the next few weeks instead of months!
Do you run an EGT sensor? Whether you do or don't, could you make a "basics" video about them, what they're used for, and how they work? Thanks.
@Grannysteacup It could be a plugged jet, main jet sounds fine though, crank seals maybe or reeds as you say, the power as you describe does not sound far off from being normal for a 125 two stroke however
@MrCaboola The stop I used was two inches not counting the spark plug
@TheRick2130 Thanks, it should be good enough to show a person if they can trust their timing light at least me thinks
Say I thought of it today, if your distributer for some reason has way too much advace curve, say like 40 degrees or something crazy, that would make it stall when it idles down, maybe something loose or broken in the distributer?

If you check their are plentiful videos showing this procedure. However, no video explaining and demonstrating the reason and the [ piston dwell] culprit.
@MGARestoration Thats a great idea, a friend comes over while the piston stop is in and sez, hey lets crank it over and your like NNnnoooo!
Well ill be damned ,i thought i knew this backwards and forwards but apparently not up and down ,nice trick ,trick a trick !
Hi, Great video, I see that some people just put a whistle TDC finder on spark # 1 hole and turn clockwise until the whistle stops sounding. When whistle stops, that would be their TDC at compression stroke. Is that approach as accurate as yours? Once determined TDC, for timing purposes, I should line up the distributor rotor to plug 1 and then go with the timing like, correct?
I had a 383 that moved the timing mark on the balancer by like 3 inches.
that could be cool if you can make a video serie on how to build an engine with junk parts on the 454 short block!
Can you offer some diagrams for people who want to front half their car eg if they were building a serious bracket car or pro mod and what are the considerations for suspension and steering and which are the best parts to use?
P.S. I've been advocating that method for finding TDC for years, and it's great for motorbikes that usually dont have pointers or marks and most car balancers always seem to be slightly out, no matter the brand
@groutaone For the sake of asking, was he the one that did the porting on your 500?
when will u make more videos on the cr 500 i like watching them
@Babynutria Thanks, for the most part the videos are fun to make, just happy someone other than my mom is willing to watch them ha ha
Nice tips,but how to know the length of the piston stoper if it's accurate or not.!!!!

@yellowbusguy
maybe on a 7 cylinder engine ;), but I think you are right..... if you add the third cylinder at the end :)
Their is an engine family that has the #1 sparkplug on the cylinder bank that's recssed...
And that's Pontiacengine family, my educated guess [ I my be wrong ] is that Pontiac Division wanted cylinder # 1 to be on the right bank.

@TheDavid2k10 Not sure on the 500, maybe when we get some water and mud in spring
Does it matter what size length bolt u use to weld onto your spark plug? Or does it not matter as long as u spin it back around then meet in the middle upon the timing wheel?
Ok which way is the most likely to slip backwards so it looks like too adv. Timing or the other way? When using a piston stop and turning motor backwards is there any chance the piston hitting the valves?
Would a dial indicator work as well if not better?
@heliarche Ouch, that bolt in there could have destroyed the engine, nice that it kept on cruising
great tips as always buddy :)
can you design a harmonic balancer for my guitar
to make me play better ?? lol
@Futurensen Thanks, would like to do that vid yet but I dont think it will be next though
@805ROADKING Its a Vivitar mini shotgun mike, looks like I will be using it for the new camera I got, the mike on this new Sony camera sucks
@Qwakkeddup One tooth off on the timing gears makes it real hard to start, bet the power was real bad
Really nice video grout!
What length do you make the piston stop? I guess it's just a reference point because you're taking the middle of the two marks.
I was wondering why my motor runs better too advanced. Just welded up a stop, spun the motor both ways and marked it, split the difference. My balancer mark was 6 degrees after TDC.
is that new 454 you mentioned a LSX?
@rebelsoutherner
Yep, this would be the timing fix for that one
@offroadjunkie89 Its been a real good engine for me, keeps on going and going
@MRSROCKINROBIN Thank you very much, always nice to hear when some guys are interested in stuff I like, then I know I'am not alone ha ha
@cubbeezx Classic 105FM, and now a word from our sponsor

@TractorWorld Thanks
How do you workout how long to make the tdc spark plug tool??????
@TMAXX22 Hmm, not sure what the next vid will be but will try to make it interesting
dose a 1994 saturn got to be top dead to torch down the rocker arms
Nice Ride ! So to find TDC you have to be on the compression side, right ? You got the valve cover's on and can not see the valves so how do you know for sure ?

You are simply measuring the longest part of the crank throw for #1, it has nothing to do with cam components.
G man ...... is that an electric water pump ? How are you controling that ? Close loop ?
yes, it was close.. but the accuracy of your stops,pen and techniques is almost a 1/8 to 1/4. so it was perfect :)
@aLexOFWGKTA Thanks
Ok, so how do you know how long to make the piston stop?
@InspectorSnatch Thanks
Hey were is your video of you cutting apart a bbc head can't find it
Sounds like you have a nice project going there, thanks for watching
I recently discovered you are friends with Roostius Maximus. I was surprised to find out you knew him.
@Gasser4x4 Thanks
Shawn..Harmonic balancer are as vital as your heart...Stock balancer's are for STOCK motors NOT Hi-Po street strip . get a fluid damper or the TCI rattler as it absorbs all harmonics do not skimp or you will pay for it when your crank N rods say's see ya..
I thought you're not supposed to turn the crankshaft counterclockwise? I love to learn, thanks🙂...
I have a video called Holley carb stumble fix that should help out
Are you using an adjustable timing light?
Good thing they put 12 volt on that waterpump, i was getting ready to plug mine into wall outlet
does the distributor have to be installed to do the compression check to find tdc?
@mrwiggles2 Turns out my new Sony has a terrible mic, so thats why I thought I would try a different one, think I will stick with it now
@ole88bluegmc Idk about amazing but I will make some more vids ha ha
@groutaone It's ok! Whenever you can! I looking forward to.. Cheers!
@sabrom Thanks for the fav
What's the firing order?It's been so long I forget.1-8-6-5-4-7-2?

@Rasd4Metta Thanks, ya wow that could waste a whole afternoon head scratching if a guy wouldnt catch that right away
@VMATT500C Thanks
@IHcubcadet Thanks for watching
very intresting
@TheFred1952 Thanks for watching
@kmac340 Thanks for watching
@upl8ter Sounds like too rich on the fuel mixture
A pontiac guy would know that the setback cylinder is number one!
Oh, I though you were talking about my head. Never mind.
great vid and ideas
@roro560v8 That length does not matter.
