Here's what PCA tech expert sez in a Q&A from 2005:

--------------------------------------

I'm getting heavy black soot on the right exhaust only. It's bad enough to coat that area of the body near the right exhaust pipes. I'm not noticing any smoke. I've broken the car in carefully. Oil consumption is exactly 1 QT/1000 miles. I've added 3.5 QTs in 3500 miles. Any recommendations or thoughts as to the cause?


You might be using oil only in maybe one cylinder on the right bank and that is giving you the black soot on the exhaust. Wait until you have about 6000 miles on the engine and see if the soot goes away after the engine breaks in. If is doesn't, I would do a cyl leakage check on the right side. There might be a ring problem there

Here's another PCA Q&A on soot AND an important link to another thread on this disturbing symptom.

Sorry to hear of this demoralizing problem again. Good luck! Keep us posted:
