View Full Version : Valve adjustment

05-28-2007, 10:06 PM
My 82 is making a valve pinging noise after I run it hard. I believe that the metal is heating up, expanding, and in turn putting a little "slop" in valves. I need to open up the old girl and adjust the valves (hopefully a slight adjustment will fix the problem) I have not done a valve job on this engine before, so I just wanted to know if anyone had any tricks to share before I jump in.. Thanks

You should not have to adjust the valves.......I'm quite sure you will have hydraulic valve lifters and they are designed to be self-adjusting. A pinging noise would more likely indicate an ignition timing problem (to much advance). I would suggest starting to look at that first.

A ticking can also be a leaking exhaust manifold seal at the head, or a hydraulic lifter that is failing to pump up with oil.:twocents:

Lucas Oil might fix this problem.

The Lucas Oil helps that much?

It seems to.

Thanks I will try the oil.. I read some where that the knocking could be caused but low octane so I am gonna get some octane booster too.. Maybe one of these will help the problem so I dont have to start pulling the engine apart in the heart of the summer!

Pinging can be a result of low octane....so use higher octane fuel OR retard your timing.... (as others suggested)

Also, check that noise (as someone suggested), it might be an exhaust manifold gasket - mine was....
