Well I just installed my new camshaft today. Its an Crane Cam 158-0012, and I installed new valve springs. Well I went to start it and it sputters and then dies. Once you get it started this loud clanking noise is coming from what I believe is the #1 cylinder. And the check engine light is on. Does anyone have an idea what may be wrong.

 

are you 400% you got the timing right.

 

What he said...there is ZERO room for error.

 

yea and i believe the idle has to be set higher for that cam

 

I lined up the timing marks on the cam and crank, according to the haynes manual. Once it idles the noise quits down. But is very dificult to get started again.

 

just do compression check that will tell you if you bent valve it is alot easier than taking the head off
