well I'm up and running and I dont want to skip steps now. How should I break in my 4.3l chevy engine. This engine is in an 8000lb van.

I have read some about oil additives, and the importance of breaking in the cam. Any truth to the hype?

Thanks hotrodders!

Chances are very good you have a factory hydraulic roller cam. It needs no special cam break in procedure- you can skip the "no idle/ keep the engine at or above 2000 rpm and vary for the first 30 minutes" deal.

More on general engine break in procedures can be seen here.

Good luck!

yea its hydraulic, and a roller set up.

IMO the most important thing for you is to prime the oiling system so it's free of air and the filter's filled completely. This will assure there will be almost instantaneous oil pressure when the engine fires.

yea I primed it as per manufactures directions. I primed for about 10 minutes until oil was everywhere and my drill started smoking and then burnt out.

Complete overkill according to your article I just read.

priming the engine cost me a drill, but it was definitely primed.

cool web site. i'm putting that in my favorites.
Thanks
