The consequence of an over-rev
Discussion
My 986 has been off the road now for almost 4 years (link to original thread http://www.pistonheads.com/gassing/topic.asp?t=123... )
Well, the fault has finally been diagnosed through stripping the engine. A bent exhaust valve, broken spring and broken tappet with a piston that has hit the valve. Likely to be caused by an over rev which is a bit unfortunate (will be plugged in to check for over revs when its back together). Here are a couple of photos of the damage. Just waiting to get the full cost breakdown for parts.
Hopefully won't be too long until it's back on the road.
