Hydraulic valve lifter problems
Haven't had a chance to read the voluminous files from the server yet, so I hope this one isn't fully covered there ... My '88 5000CSQ Wagon seems to have noisier valve lifters than I would expect. I expect the tapping at start up, but there are often several lifters making noise when idling after the engine is warmed up. I put some lifter de-gumming fluid in the oil with the last change, and that solved the problem for a while, but now it's time to change oil again and the lifters are ticking. Should I replace them? I understand aftermarket lifters are available (american-made) ... any experiences with them out there?
Thanks in advance!
