Does it rattle all the time, or change note warm or cold? Don't try to adjust the lifters while the engine's running. It just makes a big mess, and frustrates the mchanic! There's a good procedure to do an adjustment on a warm, stopped engine that works just about every time.

V8 truck engines had hydraulic lifters. Automobile 235 engines with Powerglide transmissions had hydraulic lifters starting in 1953. I am not sure about the lifters in standard transmission 235s in automobiles from 1954-1962. I think there was a 261 engine in Canadian Pontiacs that had hydraulic lifters. In the Tech Tips section of this site are a couple articles on adjusting 216/235/261 lifters. Here is a another link on adjusting valve lash.

Something I've never done before. If I knew it would make a difference on the performance of the engine..... | | |
