On most vehicles, you have to remove the transmission , but there may be an inspection plate, in order to view the rear main seal , this will give you a better veiw of both surfaces at once to determine which one is leaking. You will have to clean the whole area , and maybe wait a while , unless it's a bad leak.
You will have to pull the transmission out and remove the fly-wheel to inspect the rear main seal. It is a 1 piece round seal that slides over the rear of the crankshaft. If the rear main seal is leaking on that 2002, I would find that very odd.
Water can not leak from the rear main seal, only oil. Most likely there is a leaking freeze plug near the rear main seal dripping water onto it.
The rear main is on the end of the crank shaft. The transmission and flywheel have to be removed to service.
If it is the rear main seal that is leaking, the tranny must be separated from the engine housing.
Rear main engine seal or front transmission seals
your main oil seal on the rear of engine is leaking or the timing cover seal is leaking,
The job of the rear main seal is to keep the oil lubricating the rear main bearing from leaking out. Older model rear main seals were made from a "rope" type of material. Today the rear main seal is a one or two piece seal made from neoprene rubber and is located directly behind the rearmost main bearing journal of the crankshaft.
NO. You either have a rear main oil seal leaking or the back of the intake leaking oil and even could be a valve cover gasket leaking. But I would say the rear main is leaking and when the engine is running the flywheel slings oil onto the starter.
You can tell your rear engine is leaking by looking under your rear engine and see if there's drops hitting the ground.
rear main seal leaking
It could be your rear main seal or head gasket...is it coming from higher or lower. Higher could be head gasket, lower from rear main.
NO... They are 2 different seals. If the transmission seal is leaking then the fluid color will be RED that's leaking. If the rear main seal is leaking then it will be oil leaking from the engine and it won't be red.
