The V8 Owners Forum -

3.5 SD1 in a P6 with optical lumenition. No spark at all except one fat one on switch off! Managed to get normal sparking once when I bypassed ballast. Then blew the feed fuse and now can't recreate this. Still sparks once on switch off. Swapped coil - it was wired to earth via ballast AND fuel pump...

Beginner here...
P6 car - SD1 engine (I've been told). No engine number - just CC stamped where number should be.
It needs a new cam kit but I don't know what CR to order for. Any advice - is there a one size CR kit that will fit all without causing damage?
