I recently ran 8 ounces of Seafoam through the intake of a Porsche race car and let it soak for 5 minutes...Fired up the engine with the typical smokey result and the car idled and revved much smoother. I sent in a UOA with approx 10 hours on the oil and it came back high in lead and chromium(ring material). This engine has around 50 total hours on it and always had a fairly clean UOA, again being a race engine. I have always used either Brad Penn or Redline. Not worried really, just curious if Seafoam would impact the UOA so dramatically.

It should not produce that kind of negative results even if you ran it directly in the oil/crankcase.

My theory is running seafoam in the intake washed oil from rings and produced ring wear. Then seafoam diluted the oil and produced bearing wear.
Just a guess.
The only piece of support I have I used to have Subaru that run rich on startups. Cr showed high on UOA despite short OCI of 3000 miles. And there was nearly 5% fuel in oil. But I had no problems with elevated Pb.

If running Techron in fuel can increase lead readings on UOAs, then I would expect running something directly in the oil can do it even more so.
