Thanks for the info,
I re-installed the Alusil as well but didn't check the rings. I'm wondering if I'm burning more oil since the last 2000 Miles. It seemed to me that the first 1000 very little oil was being used but I was babying the car, the next 2000 Miles I've been running it at much higher rpm, sometimes 45 minutes at 4 to 5.5k rpm through the hills occasionally, and non stop surging to 4.5k rpm and above and back down again on country roads, just to enjoy the engine. Anyhow, since the start of the high rpm driving, it now puffs out smoke on startup more often and burns about 1L/600 miles, the first 600 miles used 1/2 litre at most. It's still less than pre-top end rework. The spec below is from the first Techspec book and was repeated in later revisions, 1.5L/1000 km was the original and continued spec from Porsche.
