Thread: Best Break in method???

Yeah I bought one of those oil primer rods so I already had oil threw out my system and I did get it started and ran it for a bit. I think I ma going to wait on running it to much.

Thanks

Don't run the motor again until you are prepared to run it from 2000 to 2500 rpm's for 35 to 40 minutes, varying rpm's during the run-in. The cam and lifters are oiled by splash off the crank and rods, so if you are only idling the motor, the cam and lifters are getting little or no oil and you will be tearing the motor down to do it again very shortly. It doesn't take long for a lifter to go south, then take the lobe out. Also, if you are using aftermarket springs, I hope you had the foresight to install worn-out stock springs in the heads for this camshaft break-in.
