I'd settle for driving nothing less than an equivalent car while it's in the shop. If you had a "problem" with cash flow in a given month you think Porsche would be ok with taking a "lesser payment"? You shouldn't be ok driving a lesser car.
My point exactly, my 997 cost me JPY 120,000 when I had a oil pump problem, my OPC didn't have the car, I told them I wanted a Boxster (wife loves them) until my car is back on the road. They ddin't like it but I got a Boxster for 14 days and we added 1000 miles to it

Finally a diagnosis. Cylinder no 4 turned out to be OK but no 6 is scored and my dealer talking to Porsche about a re-build versus a new engine. I obviously want a new engine. Given that I bought the car second hand at 18 months old, and that it is still under its original warranty, and has done less than 10,000 miles and apparently had the problem since new, would you accept a re-build??
I suspect not but your thoughts would be appreciated.
Thanks

REBUILD? THEY CANT REBUILD IT, not if the cylinder walls are scored, I cant belive the dealer would trust (or that poshce would allow) a indy machine shop to press in a new sleeve.
Are you sure they dont mean a reman/rebuilt engine, if thats the case take it they are as good (or better if you ask me) new

Nuts. Sorry Drmark. You must push for the engine. A rebuilt replacement engine would be excellent here. Perhaps that is their intention. Later.... Gerry

Firehawk - I am assuming he meant a remanufactured/rebuilt engine, and NOT a rebuild of the current engine. I agree, I can't see Porsche allowing THAT (the rebuild of the current engine) to happen!

Porsche won't move on this despite dealer pressure. Thoughts?

Ask them if they will reset the in-service date for the warranty to the replacement engine install date; or if they will extend the engine warranty only. They need to do something for you, IMHO.

Have you meet face to face with the Porsche rep or is the service mgr relaying the info back to you?

If they use a new block I would argue for a new engine warranty. Perhaps you can get them to use new crank assbly th safeguard against firehawks concern. Nothing is easy.

Cor blimey!
Porsche won't budge. Fortunately the rebuild costs are only £2k short of the cost of a new engine and my dealer has offered to waive 16 hours labour to resolve the issue. A new engine is imminent I think.
Moral of the story?
One sided sooting, in an otherwise normal engine, is a sinister symptom. And don't be allayed by normal compressions / normal oil consumption. I reckon most of the oil I was burning was coming from the one bad cylinder and the rest of the engine was as tight as a drum. And my compression readings were within the normal range.
Secondly Porsche now have a policy of paying for the most economic repair only under new car warranty - customer service seems a much lower priority - so get a good dealer. He or she could make all the difference.
Over and out!
Mark
