I have oil leak at rear of engine. Oil leaves a puddle after truck is parked a few minutes. Is there a seal at rear of engine that would remedy problem by replacing it.

Hi there,

You may have a failed rear main oil seal, if so the transmission will have to be removed to replace, or it may be the sump leaking, best to have it washed down and inspected first to verify where the leak is.
