Default 2003 911 Turbo Oil Leak

I am considering purchased a 2003 911 Turbo.

After a test drive I notice a substantial amount of oil on the drivers side of the engine near the rear. I could reach under the car and wipe it away. The part on the passenger side was dry.

Any ideas what that could be?

Camshaft cover leak but it really could be anything. Best is to get the car in the air and get underneath it with a bright light and a mirror on a stick/swivel and first make sure the oil leak isn't up high then id from where it is most likely coming.

Thanks. They think it may be a catch can.

Will have a ppi completed before I buy anything.

Who's "they"? And what catch can? I hope you do not have the PPI done by "they".

"they" is the dealer.

PPI would be completed by an independent tuner.

Apparently there is an oil catch can?

An oil catch can? Not that I'm aware of. The Turbo engine has a dry sump oil system. Oil resides in an oil tank which supplies the high pressure oil pump which pumps the oil through the oiling system.

Scavenge pumps in the heads (under the cam covers) and in the crankcase remove the oil and route it back to the tank. There is filtering and cooling involved at some point in the oil's circuit from oil tank to engine back to the tank again.

Engine crankcase fumes are routed to an air/oil separator which is designed to return any oil removed back to the oiling system proper.

There are several external oil lines that can leak along with a number of seals and gaskets. Anyone of these could be the source of the oil leak.

You need to pin down the source of that oil leak. It could be a relatively minor problem requiring just a seal replacement. On that note my recent experience with my Turbo and a leaking RMS cost almost $1700 to fix a relatively minor oil leak.

Or the leak could be much more expensive to address.

You need to know as sure as you can know what the source of the leak is and get a quote so you know the extent of what it will cost to put right should you buy the car. Of course your offer should be adjusted to take into account what this oil leak will cost to fix.

Oil catch cans.. Might translate to the turbocharger oil sump tank reservoir. One on each turbocharger. They can leak at the oring. But if that is the area, I would bet that you have a turbocharger turbine side sealing ring failure.

Who Is the dealer Punko? You need to be real careful with these cars before you buy.
