The tapping noise that I noticed a while back was really loud when I started the truck...she had been sitting for over a week. Then after she was all warmed up the tapping reduced a lot...and almost just became part of the background noise.
Is there any chance I have a bad lifter? The lifters are hydraulic on the 292...so I am wondering if one of them is leaking out while the engine sits...and then fills up after running.
What are the chances of that?

This is SOP for a old engine...as long as it quiets down after it is warmed up, it is fine.  Stuart | | |

If its chronic I'd replace them. I would use some Marvel Mystery Oil and run it for a while then change the oil and use Castrol 10W-30 and use some Lucas Addative. Should stop it. My preference is to use System 48 Plus off the net. I use it and have no valve train noise of any other mechanical sound. Just smooth and quiet. Its guaranteed. H. | | |

If they quiet down after a while,,just live with it,,if you can.
