Rear Main Oil Seal Blown

  • TOYOTA CAMRY

I own a 93 Toyota Camry LE (5SFE engine). A Toyota Dealership replaced 2 rear main seals, both of them blew out. After the first one they cleared up a slightly plugged PCV system, thus the second seal blew out. With wet compression readings of 160, 170, 130, 165. Can there be enough blowby to continuallly blow out the rear seal? Why not the dipstick or the front seal? Or can it possibly be the physical interference fit (press fit) of the seal in the retainer? Very puzzeled! ?

The main cause of blown oil seals is a bad oil pump pressure regulator. The oil pressure goes up too high and pops the oil seals. Replace the oil pump and it will take care of you problems.

Good luck losone
