I have got some noise coming from what i think is a lifter. Is there anyway
to isolate the one making the noise just by looking at it after i get the
intake off??? I have a 97 tahoe 5.7 and the lifters for it are $12 each.
Im trying to get out of this as cheap as possible. I dont want to buy all
16 and end up paying almost $200 just to fix one bad lifter. I would
appreciate any feedback
If 1 lifter has failed .....the others are not far behind.
remove the valve cover in question and depress
on the rocker arms 1 at a time with the engine running,
you will find the collapsed lifter.
BTW......who sells individual lifters ?
Every parts house i know of sells them by the set...!
Or, an oil passage has become partially blocked, or, (are you ready for
Once on my Chevy 350 a lifter started making noise so I pulled the cover and
found the tip (about 1/16" thick) of hardened metal that had been on the
valve stem. To fix it I had two choices, pull the head, replace the valve
or (the backyard way), I brazed it back on! It ran ok for several more
years before I rebuilt the engine! The reason the "lifter" clicked, of
course, was due to the increased gap when I lost the valve stem tip.
Sounded just like a collapsed lifter.
Brian happens to be correct. I don't know of many parts places that
don't sell individual lifters. He is also correct about one lifter not
being a sign of imminent failure of the rest of them. That lifter may
have gotten a chunk of crud in it that scored the piston bore or blocked
the orifice and allowed it to run dry and stick. I would probably pull
it and see what condition caused it to fail. If it was just crud I'd
clean it out and put it back in. If it was something else I'd just
