If im not mistaken it means its got new seals in it. Ive heard that saying before.

I have no idea what they mean unless they are talking about new rings . Send them a email.

Front and Rear Main Seals? (Crankshaft seals)

[zhead240]

this does not mean rebuilt? why go through the labor of resealing and not rebuilding? you got the engine torn apart anyways.

[Bambikiller240]

You don't have to have the engine torn apart completely to replace the front and rear main seals. The rear seal can be changed by removing the trans and flywheel. The front seal "may" (I've never tried it, but I know a mechanic who says he can do it) be changed without removing the Timing cover, but anyway it can be changed by pulling the Timing cover. You don't even need to pull the head if you are careful.

"Resealed" would not mean "Rebuilt" to me. There is a lot more to rebuilding an engine that "seals". Rings, rod bearings, crank bearings, and the attendent machine work, valve work, etc

You have to remove the timing cover to get to the front seal. You can do it with the engine still in the car but its a pain in the arse.

I too have heard of people changing the timing cover seal on a 'L' engine without removing the timing cover but I've never tried it. The times that I have done it I had the cover off because I was doing other things to the motor.

To me, reseal is what you do to an engine that leaks oil. Crank oil seals, sump gasket seals, and tappet cover gasket.

I did it on a rally engine after running into a tree. The front of the engine was damaged (timing cover and pulley were smashed). I pulled the sump off to check the internal condition of the engine. As everything looked ok (bit of wear in the bearings, but I knew either don't touch it, or do a full rebuild and make it worthwhile).

I just picked up a gasket kit (or maybe had one lying around, can't remember) and reassembled the engine with new oil gaskets and seals.

That engine did several more rallies until I finally sold the car.
