Gm messed up and ended up using the same lifters in the 2.2 as the 2.4 causing unnessasary wear on the base of the lifters in turn causing wear in the ball socket of the rocker roller,causing the crack in two of the rocker rollers this was a lack of the thought process on GM part. I would advise others to keep an eye on theirs as well,the guy who designed my cams noticed this as well,he showed me lifters from a cavi with 160.000thou on them and they had nowhere near the wear of mine and I only have 5000thou in milage on my car,soon as I can Im going with aftermarket lifters and rollers from Jesel

 

Do you have a ballpark figure on how much those aftermarket lifter and rollers will cost? Is it expensive to have someone install them? I have almost 20k miles on mine and my warranty is only for 36k.

 

wow mabye some one will have some aftermarket one's made soon after hearing this

 

Go to www.jeselonline.com there really is no istallation for these, you will need a re and re of the cams though, the liftersand rollers are just sat by hand into place

 

Thanks man.

 

will they work on the 2.4L? and will they work with the cam?

 

They will work,i dont if we should make tooo Biiigggg of a deal with these cause I also could have just a couple bad rockers also,not excusing the fact that the lifters are a few mm small for the socket of the roller

 

Atleast you found the problem before they got anyworse. So did you just go with the stock rockers to replace the two defective? How's the cam install coming along?

 

I bought two more rollers, I pick them up tommorro and the cams will go on,starting tommorro or the next day just start following the new thread JBP made up

 

So the 2.2 is ok? Its just the 2.4 that needs to look out? Im confused....

 

just the 2.4

 

ohhh phewwwwwwwww. hahah don't do that to me!!!

lol i was like shitttt just got all the nitrous parts now I need to fix something first lol

great post though even though im a 2.2 great heads up!

 

Maybe it's just your Pursuit Mike...*he says with all the hope of a kid on christmas*...lol

wouldn't that be covered under warranty though?

 

It sure would,but considering I tore out my cams in anticipation of the new JBP stage2vvti cams,I wont bother,just want to get these cams in the car tommorro

 

Seems to me there should be be a reimbursement or recall to some degree with the vast number of problem lifters. My 2.2 has a bad lifter (drains out over night) . I thought my oil was low but not the case. Occurs only when engine stops where it compresses that lifter. My 2009 cobolt engine only has 25,000 miles.

 

Its not a very common problem from what ive seen
