Default oil leak

Well first spot of trouble after owning this car for 2 months now. It has 47,000 miles on it and I started noticing oil in my garage. I hoped maybe the oil plug or filter wasn't tighted down good but no it has a leak.

My best uneducated guess is the rear mail seal or oil sending unit. Appears to be leaking above where the tranny mounts up to the engine.

Glad I remembered the car came with a 12 month 12,000 mile powertrain warranty!

I would look more closely at the leaks run pattern and try and determine where the leak is originating from, remember that wind from the front at 60mph tends to push fluids up hill. So it may be difficult to diagnose the piont of origin. Main seal and crankshaft seal leaking is not a very common issue, on most engines I have rebuilt the main and cankshaft seal where never replaced. Not saying it doesnt happen just saying it is rear that it does.
If possible post a pic of the oil run and general area that the oil is leaking from this might help determine the root cause.

Just got back from the shop. It's the oil pressure sensor. He knew it before he even lifted the car. Said he has replaced a bunch of these on Pt's. Anyways he has to order it and I'll get it fixed Friday. He says it only takes about an hour. That about the best news I could of hoped for.

Good news, much better than a main seal.

Your PT must be a 2003 or newer, the oil pressure sensor is located on the back of the engine block next to and slightly below the exhaust manifold. The job should realy only take about 20 minutes to complete and not a full hour of labor. Only requires 1 sensor socket and some liquid teflon and your good to go. Can be done at home if you are mechanically inclined.

I have a 2004 PT Limited - Just had a shop replace the timing belt, runs great but now it is leaking oil. Could they have disconnected or punctured anything while they were in there? The oil seems to be coming from the top backside of the motor.

In changing the timing belt, they shouldn't have gone near the top backside of the motor.

I pulled the heat shield off (snapped the 2 bottom bolts) - there is oil on the exhaust manifold on both sides but not in the middle. Will I be able to see oil coming out of the sending unit while the car is running?

If the oil is at the top of the motor and on the exhaust manifold it could be the valve cover gasket.
