    After searching, I dont think this has been asked. 1954 chevy truck 235 engine. Each time I run the truck, after about 5 minutes , smoke is coming out of the valve cover. Its a light amount of smoke. Any suggestions?

    Sounds like engine blow by, might need some rings. Put a vacuum gauge on the engine and see where it's at, you should have 17-21 inches of vacuum. Then do a compression check....Big Tim :cool:

    Also check out the crankcase breather tube. It may be clogged. Nate had an interesting method of cleaning it out on your bbq grill lmao

    In an older engine , this may well be normal .

    Do a FULL tune up beginning with valve adjustment and go from there , remembering the HOT OIL CHANGE as many don't think this necessary because of how few miles the oldie is driven .
