Title: 1955 331 valve lifter noise
Post by: alzink on May 14, 2024, 05:19:30 PM
Just had my engine completely rebuilt. Runs like a top! After 10 mile of running I began to hear a lifter noise. It comes and goes (not completely but very faint). Sounds like one lifter. I've read many comments on the forum. Run it at 2500 RPM for five minutes immediately after rebuild, put in some additives, potential of bad lifters manufactured in China, issues with he cam (band new). The engine rebuilder is recommending run it for a while and see if the noise goes away, change oil brands (using CEN-PE-Co 15-40 High performance) as recommended by the engine rebuilder, along with a multitude of other suggestions.
Has anyone be confronted with this situation and has a happy ending?

Many thanks

 WELCOME to the club.

I'd work on developing a very close relationship with the rebuilder... for the purposes of a scenario where he's committed to helping you out if the problem doesn't go away.  I think his suggestion is a good one... sometimes in the rebuilding process, bits of material get into the lifters and they won't pump up a lifter with sufficient oil to take up the valve "lash" and you hear the ticking sound. As long as you're not revving up the engine, and you drive the car carefully....i.e.: don't push the motor and drive train.  In all likelihood, the noise will eventually go away over time.  Here's a piece of unsolicited advice--drive your car at least ten miles at a time to ensure that all of the condensation is boiled out of the engine... if your engine does not have a PCV system, this is especially important.  Keep us in the loop... show us some pictures of your car.  Best regards, James

Do exactly what the builder wants you to do. Even of it doesn't make sense.

Why?? Because he is warrantying the work. Don't give him an excuse to void the warranty.

So was mine. He came highly recommended........ But he had cancer and died shortly after the engine was built. I got it out of there just before he died. He didn't do what I wanted, but it was more important to get the engine out before he died.
So, anything can happen.
