Well, my hydrolock case has finally turned into a remanufactured engine. I got a "Premium" longblock that was "spin-tested" before I picked it up. The lit that came with it says to 'break it in'. Anybody know what the breakin procedure is for a reman'd engine? How many miles? Replace oil/filter after 1000 miles?

FYI... this engine started on the "first pull"... and it runs smoother and quieter than the old engine ever was... from the day we drove it off the lot.

Thanks for all the patient guidance.

Take it easy the first 1000-2000 miles. I'd change the oil at 1500 miles, and 3000 miles, then change it every 3000 thereafter.

 

My Jasper motor required an oil and filter change at the first 500 miles.

 

I also just had a Ford reman engine installed.

The shop told me that Ford runs, tests, and breaks-in the engines and that no additional break-in is needed. He said just drive it like normal. I called the "Powertrain Assistance Center" number that came with the paper work (800-392-7946). I called twice and talked to two differnt people and they both said the same: break it in like a new engine.

From the Owner's Manual:

"There are no particular breaking-in rules for your vehicle. Simply avoid driving too briskly during the first 1,600 km (1,000 miles) of driving. Vary speeds frequently. This is necessary to give the moving parts a chance to break in. From 1,600 km (1,000 miles) onwards you can gradually increase the performance of your vehicle up to the permitted maximum speeds."

I've always heard that you should also (after a few hundred miles) get out on the highway, slow down (but not slow enough to lug the engine), and then accelerate fairly hard up to the speed limit. They want a good acceleration to load the engine, but not WOT. It's supposed to force the rings against the cylinders and help seat them. Anybody heard of this? Good idea? Bad idea?

Thanks for any suggestions . . .
