Quick update on Greff Motors. I called twice today but Randy must have been busy scrubbing out clogged Porsche pipes and wasn't able to call back.
Be sure I'll work on him tomorrow.

Before spending the big bucks, would try the following:
- Stop driving it every day. This is commuting, right? Thought is you never get the 9+ quarts of oil heated so you aggravate the crud buildup.
- On a couple of successive weekends, dump in a LARGE bottle of Techron (one for 20 gallons) , and give the car a nice 2-4 hour "Italian tune-up" on an interstate and/or lightly used back road.
If it doesn't work, at least you had some fun!
(79K miles on my 993; CEL has never come on while engine was running. Then again, this is a '95!)
All you CEL folks have me wondering about the wisdom of buying a '96 or newer 993 to replace my present one in another couple of years.

OK, I just got off the phone with Greff's Porsche guy, Randy. He said it's a PIA job that takes 10+/- hours, but it's the only way to deal with the clogged SAI ports on cars not needing valves/guides.
They pour carbon cleaner - "anything will do; Gumout, etc" down the SAI port pipes on top of the cam towers and let it sit over night. Then, drop the exhaust and, working from the bottom, use a combination of various sizes, lengths and shapes of wires through the port openings just outside the exhaust valves, manually cleaning out the buildup.
They have been doing this procedure for a year and have not seen any recurrence.
Looks like anyone within driving distance of New Orleans ought to look them up.
