Which is the preferred choice for a first 30 minute start on a completely new rebuilt engine with a Raby cam and lifters? Penn or Gibbs break in oil. Mineral oil or synthetic?
Bradd Penn, SAE 30W Grade1 Pen-7120 . Joe Gibbs, 5-30 BR30. or BR10-40. http://penngrade1.com/Products/High-Perfor...eak-In-Oil.aspx http://www.drivenracingoil.com/dro/br30-br...-oil-15781html/ |

I used Jake's break in oil.
Did you follow my suggested first engine startup sequence (edited with Java2570's suggestion): 1- Dont install the pushrods (cranking to prime with pushrods installed will wipe away the cam lube you put on the cam & lifters) 2 - remove the sparkplugs 3 - install a mechanical oil pressure gauge if you have one. 4 - do NOT fill the oil filter with oil before installation 4.1 - Install oil filter but dont tighten it, leave it loose enough that air can get out 4.2 - once oil begins to leak from the oil filter, tighten it. 5 - crank the engine until oil pressure peaks then keep cranking for as long as you are comfortable to get oil through the whole system. (Dont overheat the starter - ~10 seconds at a time, then cool off) 6 - check oil and top off if required 7 - reinstall pushrods & set valve lash (with Jakes pushrods, cold lash is zero) 8 - reinstall spark plugs 9 - proceed with engine first startup & follow Jakes cam break-in instructions |
