Rear Main Oil Seal or Oil Pan Leak? ?

2000 T%26amp;C, 3.8L v6, 145,000 miles


I have an oil leak either from the Rear Main Oil Seal or the oil pan.


I have looked under the vehicle and the oil appears to be leaking from the RMOS, but I talked to Lithia Chryser and the tech said that the oil pans are notorious for leaking on the transmission side.


My question is, Can the RMOS leak when the vehicle is NOT running?Rear Main Oil Seal or Oil Pan Leak? ?
take the inspection plate off and see if there is oil in it. you could try to snug up each bolt on the oil pan and see if it stops.Rear Main Oil Seal or Oil Pan Leak? ?
rear main seal usually only leaks when the car is running. though oil will slowy drip off afterwards. now the best way to tell is to remove the heat sheild that covers the flywheel and look at it and at the flywheel . is the oil only on the engine side of the cover or is it inside the cover and on the fly wheel. the rear main seal will leak into the bellhousing and on the fly wheel the oil pan gasket will leak on the front of the heat sheild.
