I have a 1940 Chevy 4 door sedan. I installed a 235 6 cylinder from a 1957 Chevy car. The engine sounded really good before it was removed from the car. I then installed the engine in my car. The engine ran really good in my car. Then I got busy with other things and parked the car in the barn. The car sat for about 4-5 months. Today I started the car and there is a tapping noise coming from under the valve cover. What could be wrong and what can I do to fix it?
Thanks

Possible a stuck lifter from sitting, I've seen that a few times on motors that been sitting for a long time, oil drains down on them.

If it doesn't come out of it from running a while but some sea foam in the oil, 1oz for every quarter capacity the engine is.
235 valvetrain should be set up like a small block or big block Chevy, pedestal mount adjustable rockers. It should be zero valve lash . I always adjust them running, pull valve cover fire it up let it idle start from either end, SLOWLY loosen the fulcrum nut until you hear the lifter clatter, this will " clean" the plunger in the lifter, then SLOWLY tighten the nut just until you hear the tappet noise stop, then go 1/8-1/4 more.
I've done this many times it's the best way, you do it by hand on an engine to get close but do it running once in the car bc guaranteed they'll be too tight by hand.
