Mine's got ~170k on it. Always changed the oil regularly. I've only owned it since ~90k but I don't think any kind of maintenance has ever been done on the valves - should I check clearances, what that tell me about the noise? I've heard that top end noises get WORSE with rpm's though, not disappear. Any help is appreciated, thanks. |
Is it more of a ticking and does it get faster as rpms go up? if so valves.
The problem could have nothing to do with the tune up. It could have happend at the same time w/o the tune up. A quick fix would be adding 8oz of marval mystery oil to the crankcase and the rest to you gas and see if the noise goes away..
