last fall I blew a capped air injection tube out of one head in my '76, so the engine has been refreshed. Barrels were pulled and honed, fresh rings and a set of rebuilt '73 heads and a new oil cooler. It will be reinstalled in the next few weeks and plan to change oil after a few short drives. I was using Mobil 1 Extended Performance 15w50 based on a local Porsche shop. I've got a case of both 20w50 and 10w30 Brad Penn in the garage in addition to the Mobil 1.
What would use and how soon would you do the first oil change. Doesn't have to be any of the above. Recommendations appreciated. Dan |

Yes you need it. You could wipe out your cam lobes without it.
And you need to run the Engine at a specified RPM for a specified period on initial startup. |

Cam break in not needed (IMG:style_emoticons/default/agree.gif) The BP 10w30 should be good enough for seating the rings. If she runs fine on start up just drive it like you stole it to seat the rings. |
