Message I noticed that My Z was smoking a little out of the PS tailpipe after the drive to to the ZNationals. I also smelled oil.
The engine was making a clicking noise after my drive back from Georgia, and I assumed it was low on oil.
I have no way of checking the oil, since there is no dipstick reservoir as it was overlooked when the engine was installed by the previous owner.

I drained the old oil for an oil change, and there was just a bit over 1 quart in the engine!
The bottom of the car was covered in oil on the passenger side about 2 feet after the downpipes.

I had the spark plugs changed before I traveled down to ZNationals.
The previous owner had NA plugs installed. I had a lower temp NGK plugs installed.
I also wonder if it could be one of the engine gaskets on that back PS side of the engine.
I had a bad acid leak from an Optima battery back in 2008. I ate away at alot of parts on that side of the car.
I wonder if some of it ate away at the gaskets, and they may finally be blowing out??

Battery acid leak aftermath:

I took some video of the area where the leak is coming from.
Keep in mind that this was after the long road trip down and back, so she's dirty below from the dirt, debris, and oil.

I'm guessing that it may be a seal or something on the turbo. There was oil splattered all over the back of the car,
so oil must be getting into the turbine, and blown out the exhaust.

Oil on the back of the car after returning from Georgia:

Any ideas??

Shot from under the car:
Again. Keep in mind that this was after the long road trip down and back, so she's dirty below from the dirt, debris, and oil.
