My engine is a 31C707 0154E1 050228ZA. I have the camshaft out and am trying to determine if the cam lobes have slipped on the splines causing the valve timing to be off. Does anybody know at what point(in degrees) each valve is supposed to open.
Both alignment marks are together. I was told by my parts store guy that the lobes can slip around the splines they are pressed onto, causing mistiming. My old one has no obvious defects visible to the naked eye. He sold me a new camshaft. Compression is releasing now during starter spin(like it's supposed to), but it will not start. It backfires every few turns now instead of backfiring more often. I initially set it .003 int. and .005 exhaust but it just backfired really loud. Through trial and error (making small adjustments) it backfires less often and quieter, but still won't start.
I'm stumped now.
