I drove the turbo on Sunday after it sat for a week or two. When I started it, it smoked from the left tail pipe for about 45 seconds. Not the puff of white smoke that occurres now and them. This was some very visable and prolonged smoke. I drove the car and it ran great.
Last night I found a small amount of oil on the ground under the right side. I started the car and there was no smoke at all.
From my search on prior postings regarding oil leaks, it appears that I have an issue with the right side turbo. What I can't tell from the postings is if this is a minor seal problem or a major rebuild.
I have 41,000 miles on it now and the PO had both turbos re-build at 29,000. Oil was changed 2,000 miles ago and the OEM Porsche filters were used. No oil was been added since the oil change.
What do your think; minor or major? TIA

Chuck,
Did you just get an oil change, or possibly add some oil?
Further, are you sure you have a not-overtightened Porsche branded small filter?
Might want to see if it happens again.

Chuck, this may be an excellent "opportunity" to upgrade your oil lines to those with the check valves. See Kevin's latest work at UMW. Once installed, you should clean your intercooler, and you may be fine.
Turbos generally will last 60,000+ miles if properly cooled. I think you are OK.

Yes; very slight angle in my garage. Enough though that there was a three inch diameter circle of oil with a 7 inch tail running down the the floor.

Looking at the reciept of the turbo rebuilds it shows that they used Andial lines. These have the same function as the lines that Kevin is offering. I'll loosen up the oil filters and see if that helps.

Here what Kevin said earlier this week:
The filter fails and oil migrates from the main engine oil tank into the engine case (thru the oil filter)..
The updated/revised/oil return-sump tank lines prevent the oil from migrating to the turbochargers thru the "back-door".
I had a LA Porsche Service Manager call me last week. He mentioned that he instructs his techs to ONLY thread the factory engine filter 1/2 turn once the rubber lip seats. He then puts a hose clamp around the oil filter and safety wires the filter to prevent it from backing/spinning off.
I don't recommend this suggestion. I do crank the filters on hand tight to nearly a full turn. The risk is to great to have a filter spinning off.

For what it's worth, I had the same problem as Chuck. Porsche filters always. Hybrid turbos went on the car at about 45K. Car now had about 62K. Andial lines on the car, but no check valve on the inlet side. Started with "more than usual" smoke on start-up. Smoking got worse, then a puddle on the (flat) garage floor.
Ended up having the turbos rebullt - it seems the seal at the thrust face may have been leaking. Installed check valves when the everything went back together. So far, so good (until my second cracked Fikse wheel sidelined the car...
). Hopefully I don't see this again in the next 20K miles - I try to be very kind to the turbos on warm-up and cool-down.
An over-tightened oil filter is a MUCH chepaer fix, so definitely persue that avenue.
Best of luck!

What is the issue with the cars smoking after being parked with the front on an incline ? Every time mine is it leaks oil from both turbos (which were recently rebuilt and the check valve kit was installed) onto the ground and smokes on startup for a few minutes ?
