HI, for the most part not really for brake in.. the filter should catch anything that may be wore .. Now cam brake in is 2,500 rpm's for 20 min's varying rpm's to 3,000 every few min's.. Be sure to check your timming.. Not knowing what kind of auto/truck but I think timming should be about 36* at like 3,000rpm's.. once you've completed the cam brake in you should be able to drive the car like you normal. If this motor is rebuilt someone else they may tell you to baby it.. Don't .... if you baby it your just wasting you warrenty... you want it to brake while under warrenty .. but don't try to brake it .. just drive it normal... I've rebuilt several of my own motors and never babied them. they still run strong and no leaks or smoke..
good luck
tim
Break in oil was marketed to get around the law about banning "zinc" in oils a few years ago. Our Govt (EPA) approved
break-in oil with the assumption that the owner of the car will remove the oil, classified as temporary. But Zinc is critical for flat tappets cams. Some of us use break-in oil permantly. It comes in 10-40 & 10-30. Look for it at Jegs or Summit, search "zinc oil".
After break-in, you should change the oil, refill with more zinc. And yes, run the magnet plug all the time including one on the pan or filter.
Break in oil? Never heard of such a thing. Magnet ought to not be needed.
Rebuilt or replacement components ought to be treated as normal items but driven or loaded less for a short period of running in. Cams in particular ought to avoid lots of idling at first and top end speeds.
If I thought it was a Ford, there is the FL-1HP oil filter designed for this. But you did not Identify anything
you should dropped a good magnet into the pan.
When braking in a new engine. Should I use a magnet on the oil pan? Im using brake in oil. I didn't know if the magnet would effect the additives in the brake in oil.
