Make sure the oil pump is primed (normally full of grease or vaseline). Also make sure the lifter bases and cam is covered in cam lube. Crank it over with the coil lead removed until it gets oil pressure, then start it and run it for 20 minutes at around |

Tim,
Byron is correct here is a bit more.
(1) When its a "never been fired up" donk there is no oil in the lines/journals. Per Byron. Nor is there oil at the rings ! My Dad always told me to put/squirt a small amount of engine all into each cylinde

Use non-friction modified oil for the first 10,000 k's. The friction modifiers will greatly hinder the bedding in of your motor's internals. I agree with John and Byron's advice above, except I usually change oil and filter at 100 k's, then oil at 500 Edited by user Wednesday, 26 October 2005 8:19:35 AM(UTC)

All of the above....
Squirt oil all over the valve gear as well before fitting the tappet covers.
We use a rattle gun at work to turn the engine over until oil pressure is obtained, before starting. |
In thrust we trust |

Not sure on the non-friction modified additive. Usually the older specification and/or cheaper oils are non-friction modified. They are getting harder to find these days.
If you use friction modified oil early in a motor's life, the teflon in it coats

I should have added that the Friction Modifiers are an additive to the oil in the first place...
Cheers...Dave

You have to be careful about what oil is and is not friction modified. I once put an oil into my motorbike that didn't mention friction modifiers but the result was a badly slipping clutch caused by the friction modifiers. A couple of oil changes later us |

Hence my comment from early on !!
NOTE: Teflon stuff is fine for cams, and lifters..but not for the rings !!!! OK ?
