Lifter noise (how to fix)

[eric99gt]

Well over the winter I had my heads done. They were port, polished, milled. The works. I also had some LS1 springs put on. Well now with the car all back together I get some pretty good lifter noise. Any ideas on what may be causing this and how i could go about fixing it. Some other info, never changed the rockers while i was in there, they're still stock. Also lifters were never changed as well. This is all on the 3400. Thanks for any help

I would check how tight the rockers are, maybe the place that did the work didnt get them tight enough. How many miles on the lifters?

[eric99gt]

i did most of the work. i just had the stuff sent out to get p&p. I though i had tightened everything down to the right specs. The lifters had about 86,000 on them.

Go back and make sure they are all tightened right down. They are non adjustable

ok say i tightened everything down to the right torque specs. what else could be the problem???

[geoffinbc]

Still loud? Hmm hows the oil pressure? Is the sump full and the pump picking up? Is oil comming out of the pushrods at the top?

[eric99gt]

oil pressure i'm pretty sure is good since i'm not getting any idiot lights. the rest i'm not sure on cause the valve cover is still on. when i get a chance i'll have to rip it off again.

Well you can remove the frot one with no hastle. Best go and check

I know the rockers do not need to be replaced, Most people replace the lifters when they put in a new cam.
