Is there any of this film on the crankshaft pulley, or in that area? Is the film oily?

If you shine a strong flashlight down into the tin below the crankshaft pulley, does it look wet?

How about the cam chain cases on the rear of the engine, any wetness, dripping or seepage from them?

 

And the spoiler wall?

In your photo above, either the inner belt has not been replaced, or the roller is pressing far too hard - look at the indentation on the belt. If the roller is jammed, you'd expect a burning smell, but if it is digging into the inner belt then that may explain the 'soot'.

 

I did check that idler Pulley and it spins fine. I’d say that belt hasn’t been replace.
Now that i researched the spoiler wall i will go check that out

 

Spoiler wall is in tact,perfect condition. I am going to clean this up and monitor

 

Good plan.

You don't park it down a coal mine, in New York, do you?

 

How much oil does it burn and how full do you keep the oil on the stick?
shouldn’t be above 1/4 up twisty section
i keep mine at the bottom

 

I am new to the 993 only 2 months in and new to air cooled Pcars. I only drove it about 300 Miles and now the weather up in NY has been Snow. I’m going to to clean it up and monitor. Will check the oil level later today. Wow a lot to learn on these cars, but i love it!

 

In Long Island, Only sandy Beaches!!

 

No Oil and all clean, well Dry.

 

If you’re snowed in it’ll have to wait. Oil level check has to be done with a hot engine while it’s running - dry sump process. Lots of discussion here.

 

Yes, read all about the oil levels. It’s 45 and sunny, snow is melting. Later this week.....Ive got to get her finished from the front end restoration.

 

There's a cobweb on the ceiling, near the striplight.

For heaven's sake man, clean it up

 

I was going to say, that finish really shows up the flaws in your ceiling.
