Engine break in and seating the rings????

[Mike Delahanty]

I have become a real believer in the Gibbs BR break in oil. I would not start a new engine without it. Power levels and ring seal stabilize within 2-4 pulls on the Dyno. Engine disassembly after Dyno break-in looks like the engine has never been run. I also like the Gibbs engine assembly lubricants and see them in many of the high end engine builders assembly rooms that I visit.

Now, how the crap can we believe what you say---ya work for Ford, a drag racer duing roundy round, and driving a MoPar. Being that scrwed up, I wouldnt let u in my shop. HeHeHe Oh bye the way, I totally use and believe In Joe Gibbs oil and assembly. The assembly lube does not blind a filter and I have found several assm. lube that will blind certain filters. Best I have found on the dyno.

The best thing you can do after getting the proper hone (an art in itself) is to apply the Total Seal paste that you burnish to the cylinder walls. I can't find it on their website but it was developed by my engine builder, Bud Yancer of MACH Development. It is sold and marketed (?) by total seal. After that, Gibbs break-in oil. With anything coming out of that shop, leak down after dyno break in should be around 1%. And that's using gapped rings.

I was told years ago,engines broke in fast run fast,we rebuild diesels engines at work,we fire them up.idle a few min,then take them on road test

One of the biggest things I have found is don't let it sit and idle before running it hard.
