Hey guys,

I have been tearing down my 4.8 Vortec to make sure it's up to par for the swap into me JEEP YJ. Anyway when doing so I found that every second roller lifter had a spring that would work and then the next one would not! It seem that the lifters on the intake side are the ones that have give and the lifters on the exhaust side seem to be fixed. It's just wierd that every second one would be shot and that it was not suppose to be that way.

So my question is, can anyone tell me if this is the way they are suppose to be or do I have **** lifters that need to be replaced or rebuilt. It looks like I can take them apart and clean them to see if I can get them working again.

I hope I've made sense of this and any help would be appreciated.

Thanks, Jay

im not really up on the LS based motors yet but I have a close freind that has just completed his 5.7 LS1 swap into a 2wd s10 . he'd probably be more than happy to help if he can Email him at lunatic515@aol.com. By the way after driving his truck I've gotta dump my old school 350 for one of those things. hope he can help his names mark

Thanks for the reply,

I finally had to find out for myself and take'm apart to see what was going on inside. Well it turns out that the four that were not working, were not working! They just needed to be cleaned up and re lubed and out back together. So I think they will be ok now!

Thanks, Jay
