To make a long story short, I broke and bent two of my pushrods in my stock LS1. After replacing them, I fired it up and all seemed to be normal except for some significant power loss. I did a compression test and discovered that all cylinders had 150psi -- perfect. That lead me to believe only two things could have happened: collapsed lifter or chipped cam.

I have never changed a lifter or cam before. I have a TR224 sitting next to me and I will be putting it in at the same time I inspect/change the lifters.

My question is: What do I have to do to inspect the lifters, and how will I know if one is bad? Where to get replacement ones, and how much (approx)? What parts will I need to do this (gaskets, head bolts, etc)?

Thanks a lot for your help guys, and I hope I can get this worked one once and for all!

 

Are you sure you got them all? Just 2? That would be pretty unusal....did you eyeball them or roll them on glass????

 

Well, actually, I just checked the passenger side. I probably should do drivers side too huh?

 

Yes, there are at least 2 more I bet.

 

Okay did the drivers side, not a single bent one!

So on with the original question, can someone please guide me through installing a lifter? Is there a way to check if one is bad?
