Motor break in results are in
 

Was up at beerbongs place today, thought I'd throw his comp tester on and see how things sealed up.

Cylinder 1 - 210psi
Cylinder 2 - 210psi
Cylinder 3 - 210psi
Cylinder 4 - 210psi

I'd say my break in methods worked pretty damned good. To those of you that don't know. This is a rebuilt d16z6 bottom end, machined crank and connecting rod ends, ACL bearings, new rings, fresh cylinder hone.

Test was done with 593 miles on the block.

The only thing I am wondering now, is that I still get a small puff of blue smoke when I get on the throttle, so i am guessing its valve seals, high mileage z6 head was simply re-used.

Also its running lean as ----, plugs where white as hell, but I'm not too worried about it, I am running the stock p28 and completely stock fuel system. No boost so it shouldnt hurt.

Otherwise, not too shabby eh?

What method of break-in did you use?

Good luck with this motor. I hope it works out better than the last 35 of them. ;)

35...haha

Well my break in kinda went like this.

Took it slow and easy to the freeway, which was about 4 miles. Got on the freeway and pulled in 3rd to about 3000rpm and let the compression of the engine take me back down, but not so low i had to downshift. I repeated that increasing 1000rpm each time. Once I got to 7000rpm I started over in 4th gear. I did the same thing, only didn't make it to 7000rpm in 4th, I'm guessing only about 5500rpm or so.

Overall I think I covered 15-20 miles like this, then I just drove it pretty mellow, never revved over 5500 or so the entire time, and at 593 miles tested it out and got some nice results.
