LT5 Assembly Project

Footnote: with the heads on it takes only 24ftlbs to rotate the engine vs the 36ftlbs before.....


I replaced the timing chain guides wear strips, the book states that the wear strips should be replaced if there is 1mm or more of wear. I used guides from White Racing LLC. The stockers were gold colored, these were silver so I assume they may be repros...


To replace the wear guide strips you simply tap out a pin in one side of the guide with a small drill bit and then reinstall.....easy




I did make on error, the book has you put the timing chains, guides and gears on before the heads....I did not. That did not make much of a difference. I did need to remove the secondary timing gears in order to install the guides.

I placed the bottom guides in place with bolts using loctite 262 and 20ftlbs , slid the top chain guides in without bolting them in....I then dropped in the chains and the put the secondary timing gear in(but set it in the chains, did not press it in place or bolt it in)....I then bolted in the top chain guides...loctited and torqued to 20ftlbs. I then lined up the primary timing chain on the crank sprocket and pressed the secondary gear in place....the bolted in the 3 bolts and set to 20ft lbs.





Pete thanks for the tech tips!

PS if are having issues getting the 2ndry gear on flip the engine over, it will take the slack out of the chains and make it easier!

I used the Kent Moore tools to hold the chains in place......I know they are backwards

Been watching this thread and just wanted to say thanks for taking the time to document everything and share it with us.

I agree with what you said about satisfaction of doing it yourself and learning something along the way..

great job.

Thanks, been interesting....I just pray when all is said and done it revs to 7500 and stays in one piece......it has not been too scary so far...cam timing will be the big challenge.

cam timing is a piece of cake. But paying the greek is a bitch. Just watch your back,,,,,,

Added some pics above regarding timing chains/guide/gears......


Nothing too exciting tonight put the breather box on, pretty easy....gasket, baffle, and box.....

Well cams/lifters are in, just need to do the timing to wrap it up. Ran into one issue today...one of the guides was sticking. I figured it was just some stray loctite, but want to make sure. I took it apart and sure enough, loctite got in the bushing. Cleaned it out and no more issues.

Had one more scare, thought I had the chains in wrong, but it was just a matter of chains loosening up...was difficult to get the Exhaust cam in, but once in and rI otated the engine it was perfect!

Well, project should start wrapping up in soon.....Better get my plenum painted

You guys probably know all about this site? I found it when I was searching for places to buy new T/Q wrenches. I just figured I'd pass the link along.
