Really dumb question. This 'project' car leaks like a sieve. The RMS leak slowed a lot since I added some RMS conditioner to fresh synthetic oil.

The rear cam seals show signs of leakage, but not bad. The turbo oil return line seal and gasket need to be replaced, but the leak is minor.

I pulled off the cam cover because there was a lot of oil on the subframe, covered in a layer of sand and dirt. Last September, when I pulled it off, the inside of the cover was covered in oil! I washed off the oil, noted that I need to change the Tbelt and clean everything. Puzzled, I couldn't find any oil around the front cam seals.

Yesterday, I pulled off the cover again. No mess?!!! The edge of the Tbelt has oil residue on it, but not fresh. So what is happening? Where did the original oil come from?

There is a small channel that oil could leak down from the spark plug area. That was a real mess last summer. I cleaned it all up with a few paper towels, except that channel under the tbelt cover. Put on a new oil cap gasket after a new PCV. No more new oil in the spark plug area, and now no additional oil under the Tbelt.

There is no other explanation, unless you can think of one. Oil consumption is about 1qt/1,000 miles, which includes the amount on my garage floor which has to be a major portion of that quart.
