Still does this, but there is now a camshaft rattle noise when ticking over.
It is only coming from the right hand engine cover.... so im.presuming is there and camshaft related...
Still there at higher revvs but harder to hear....
Is this engine an overhead cam with the cams directly under the covers or are they buried.... how easy or difficult is it to fix a noisy camshaft....
