The oil leak is in the area of the starter. Does anybody know any oil seal in the starter mount? If it is, how to replace it.

Fred with all due respect are you sure it is coming from the starter where it is mounted to the engine? The started mounts to the engine and engages the flywheel upon starting the engine. There is no seal in this area that could leak engine oil.

But look above the starter and find the oil pressure sensor (sometimes called the oil sending unit) and see if that is leaking and allowing oil to run down into the starter area.

Oil could be leaking from the rear crankshaft seal allowing the oil to be "blown" up and on the starter and then leak out at that point. Not likely. Most of the time rear seal leaks drain out at the bottom of the engine at the back of the oil pan.

Is there oil on the ground when the car sits during the night?

How much oil is coming out?

Let us know.

Thank for your reply. You are right, I checked with dealer's drawing;there is no seal around the starter mounting. I already replace the T-bone gasket and oil pressure. I checked on those areas they are dry. I think you are right, there is the oil on the ground when it sit overnight. I need to fill the oil every two weeks or 400 miles. It should leak in the rear crank seal. Do you know where it is? Does it connect to the automatic transmission? When I rebuilt the transmission, I asked the mechanic to replace the seal. He told me he replace a new one. Is this seal different from the crankshaft seal? I appreciate you to give the help.

Thanks,
Fred
