Cam breakin Procedure

ValiantMike said

I just buttoned up my 318. Installed new cam, heads, lifters, springs, retainers, headers, etc.. I fired it up for about 10 seconds then shut it down. What I need to know is, what is the procedure to run it for breakin, and how long? Anything special, or just run it? I'm using proper type oil, additives, coatings, etc.. Thanks Mike

Unfortunately, by running it for 10 seconds, you have wiped all cam lube off the lobes without running it long enough to break the cam in. That's a big no-no. You should have kept it running for 20 minutes. You can take your chances and break it in for 20 minutes now and hope for the best. Or pull the intake and re-lube the lobes as best you can.
