Found this on the www awhile back and thought I'd post here to see what you all think.

Hmmm....It makes sense in reference to the rings, but totally omits concern with breaking in the cam and lifters.

definitely need Jake or Brads input on this one.

This is very timely. I hope to get mine back with a new 2.0 engine next week; need some additional parts (my mechanic has that dreaded disease discussed in earlier threads and I'm glad he does). Anyway, when I drive it home, which is 40 miles of twisty, hilly road with some straight, should I drive as I normally do - at the top of the range for each gear before I shift up?

From reading the article, it sounds like I should. And does that mean that's all I have to do? My mechanic will be doing the first oil change, etc. before I get it.

1- Crank for oil pressure
2- ensure the engine is actually ready to fire up
3- fire it up and look for leaks and listen for sounds
4- let it run at no les than 2500 RPM for atleast a half hour, DO NOT let it idle!
6- Shut it down and let it cool off completely, then let it run again for 15-20 minutes and then you can let it idle.

7- install it into the car, drive it just like you normally would. If you drive it a long distance vary your speed.... Don't be afraid to wind it up, if its gonna scatter it'll do it whether you pussyfoot it or not..

I fire them up and break them in and take'em straight to redline and beat on them for 8 hours.

Is that for non ceramic lifters or all types?

Thanks Jake. My mechanic is going to do items 1-7 1/3 and I'm doing the rest. Just didn't know if I had to be careful on the way home. On the road home, I have no choice but to vary my speed.

With ceramic lifters just crank the engine and let it idle right off the bat. They need no break in. They are indestructible.
