Only by replacing the seal. Just dive in and do it, waiting will only make the problem worse.
You have rod bearing caps that hold the rods on the crankshaft. And you also have main bearing caps that hold the crankshaft in the engine block. NEUTZ.
because their piece of junk!
Refer to specifications section of repair manual. You can find it at local library or buy it at local auto parts store.
I suggest taking it to the auto trim shop as it is hard to find the leak and hard to stop it and they do it all of the time. Roof Leaks identification and material selection for repairing roof leaks is a main concern.
1987 and newer requires removing transmission and flywheel to gain access to the rear main seal. The seal is one piece and easy to replace once you gain access to it. 1986 and older requires removing the engine oil pan, oil pump, loosen all main bearing caps, remove rear main bearing cap, replace upper and lower halfs of seal. The upper half is tricky but it can be done. All bearing caps would need to be torqued to specs for assembly. I would suggest purchasing a shop manual for that vehicle if you decide to do the job yourself.
You need to replace the oil seal.
The main reason to replace the rack is a fluid leak.
Front (side away from transmission) is cheaper by far. Around $100.00 is my GUESS.
You can the Lucas oil additives, but, in the end, you're still going to have to replace the rear bearing seal.
main bearing whats happens when goin out
What is the torque for the following Nissan navara QD32 1)main bearing cylinder head 3)conrod bearing 4)fly wheel
Worn out main bearings, PCV valve not working. If it is a straight stick then the thrust bearing on the crankshaft may also be worn out letting the crank move in and out.
Oil will not handle the heat, main pully bearing will heat and burn out causing pump to leak
The rod bearing torque spec from mercruiser is 45 lb there is no spec that i can find for the main bearing caps.
The main bearing bolt torque for the Nissan TD 27 is 70 lbs ft. This is the bearing to the block.
You should not need to remove the main bearing cap, in order to replace the rear main seal. The rear main seal will come off without touching the main bearing cap.
You can tell if the main thrust bearing is bad by simply checking out the oil. If you notice little metal particles, chances are the thrust bearing has spoiled.
