Question about Pontiac LeMans
Just changed head gasket. put everything back how I found it. Lifters werent't noisy before. no coolant in oil. what gives?
Really, really, sorry to suggest that the head gasket may not have oil passages lined up. Always lay the oil gasket over the new gasket to see if each and every hole is punched out and lines up to the old gasket.
Also, each lifter needs to go back to its original spot. The Cam lobes are worn for that lifter and a mismatch can be possible. A mismatch could mean extra play in a badly worn lifter face mated to a badly worn Cam lobe.
If that is what you did then get new or rebuilt lifters. Check out Compcams.com for a detailed description of each engine scheme. Your engine may have a thrust plate for the lifters and it may be incorrectly installed creating noise.

The camshaft may be worn or the lifters .that explains the missing when you run it at operating temp.By the description of the oil. the reasomn the canmshaft wore out and the valve lifters is because the oil was not changed on a regular basis.

Remove valve covers, remove rocker arms and push rods, remove intake manifold, remove lifters, (special lifter tool may be required). Reverse steps to reassemble. Make sure to use new gaskets.

SOURCE: noisy lifters?
some anti freze may have entered the oil when repairs wrer done, check oil first, but the 3.1 has solid lifters and is a comon problem to make ticking noise, the lifters are about $60 each x 12, my friends olds 3.1 has made that noise for 10,000kms now, wreckers may be an option

more than likely you will need new lifters but i have gotten away with substituting 1 quart of atf for one quart of oil on an oil change that seems to work good and make sure you don't use any thick oil treatments and are running 5w30w oil..
