Hi guys,
today i fired up the spare engine. Makes a strange sound like tac tac tac.
Anybody knows what it could be? Think it comes from the right head. Valves are fresh adjusted.

Is it true that over time as the valves get "out of adjustment" that they actually get tighter? not looser? |

I dunno man, it sure sounds like valve lash to me. It gets quieter as the engine warms up. Plus, when you give it a little throttle, I don't hear anything. So I don't think you have a bad wrist pin or rod knock etc. Those stick out like a soar thumb when you bump the throttle. .015, dang, I am at work right now and can't remember the conversion. Is that .006"? Most people I know do .006 across the board, but if you live in a cooler climate, I would go .004 intake and .006 exhaust. Pop off a valve cover and check the #1 again. Maybe it is the rockers? It is valve train noise for sure though. I have heard that a bazilion times. Other than that, motor sounds great! |

Sounds a little like my engine as it's warming up. I recently adjusted my exhaust valves to .008 and that's what they sound like. It does quite down quite a bit when warm/accelerating. I assume this is a fresh rebuild? |
