Thread: Noisy Tappets in 3.5 V8

This is EXACTLY what has happenned to mine. Any idea of shim size, where they came from and how successful it was please?

Djam, that shop I will not name that told you not to bother with the preload hasn't impressed me so far - and I only got as far as trying to get some email answers from them. I don't know why they told you that.

You have to check the preloads on these things, regardless. I just rebuilt a brand-new crate engine that had been sitting for a long time, so I pulled it apart. It still needed checking when it went back together with factory original heads, block, rocker pedestals, you name it. I used spendy adjustable pushrods, which were a neat way to do it.
