Hi:
My Jeep AMC 360 has a severe rear main seal leak problem.
The mechanic also found leaks at the intake and timing cover and possibly the "R/S head" although I 'm not sure what that means.
He suggested removing the engine and resealing everything for which I am quoted $3,600 (which includes a new timing chain & engine mounts and for other reasons a radiator replacement).
He fears that bearing wear may make the crank too sloppy to allow a new rear main seal to do its job, which might necessitate an engine replacement, for which I am quoted $5,500 (also including radiator, timing chain, new engine mounts). This is for a Jasper engine.
Having heard worrisome things about Jasper, I am also considering the following rebuilders:
ATK Doughtie Promar S&S Powertrain Products Inc.
Comments and advice would be appreciated.
Frank
