Hy there

First of all, Sorry for my bad english i try to write as good as i can.

I have a Problem with my Engine. It whistles, getting louder with higher Temperature and the pitch gets higher with rpm.

I think it has somethink to do with the camshaft or valves.


While i can replace the Camshaft and Hydrolifters i am not sure about the camshaft bushings. Are those replaceable? or do i have to replace the whole head if they have runmarks?

Thanks for the Help.

Mike

A whistle would imply air leak. Tappety sounds (typical CVH) are usually cam/rockers

Thank you for the reply

i ll check for air leaks. i got tapety sounds too. but only around 3000-4000 rpm ... if i go higher or lower they are not noticeable
