Is it worth fixing rear engine seal with car that has 205,000 miles?
I have got a 1997 Plymouth Breeze. It’s the same type car as the Dodge Stratus. The car has got 205,000 miles. It’s started leaking oil at the rear engine seal. The car still runs real good. It uses very little oil (about one quart every 3,000 miles). My mechanic says that a car with that many miles though has probably started losing compression around the piston rings. The compression is blowing into the crankcase and putting pressure on the seals. I had the timing chain assembly replaced at the front of the engine about six months ago. It was leaking oil there. It’s now stopped leaking oil at the front and is dry there. The mechanic says that if I replace the rear engine seal the compression loss will probably cause pressure on the other seals and the weakest seal at a different location will start leaking. He says that it may not be worth the expense to repair the engine. Can somebody tell me if I drill a hole in the oil fill cap on the valve cover will that let the blowby escape an
