Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hello fellas Just left a deposit on a 996, 1998 model on 72k with full Porsche History. I know these cars are 'supposed' to have a bit of sludge on the oil filler. This one has quite a bit frankly. Seems to run fine, and the water tank didnt have any evidence of oil mixture. Picture is attached. Can anyone advise? Thanks Zain. /images/migration/UploadedForumImages/911%20sludge.jpg Migration info. Legacy thread was 139226

POST 2Original post

Could be head gasket ?? But you say there is no water/oil mix in the water tank !! If a car is not used for a while the 'sludge' can build up.. it maybe worth taking the car on a long (ish) run and have a look then ! But a PPI (which I hope your going to get done?) will confirm any problems !! Welcome to the fourm by the way.. Whats the full spec of the 911 you've bought ? Migration info.

POST 3Original post

POST 4 / ORIGINAL POSTEROriginal post

Thanks fellas. Just switched over from the world of E30 M3 (mines the white one on ebay if interested) Its a 1998 C2 Tiptronic, black, full aero kit, 72k with full Porsche history, fully specced with sat nav, comms pack, savannah leather etc. Very nice, what would you say, valuation wise? He hadnt used it in a couple of weeks, and it just had a major service in March, and nothing is noted on that invoice (which is the only specialist and not main dealer visit). Guy is minted so money wasnt an issue in his 6 years of ownership (he bought it for 55k from main dealer, Ive seen the receipt), as brand new discs, pads and Pirelli PZero's suggest. Ive left a deposit, but in the agreement that Porsche compression test it next week. Is that sludge excessive? These 996's have head issues dont they? Migration info. Legacy thread was 139239

POST 5Original post

That's quite normal for a low use car, no oil top up, short journeys and you'll get the mayonnaise build up you see here. Migration info. Legacy thread was 139245

You reckon thats not excessive Damian?? Migration info. Legacy thread was 139426

POST 7Original post

Check for oil in 'blobs' water that's generally a more reliable indicator of head gasket problem. sometime you can see bubbles in water when engine is running.. Migration info. Legacy thread was 139468

POST 8Original post

I think there is something you can buy to check if there is oil in the water, its like a paper PH strip.. I can't remember where you get them from (maybe Halfords may do them??). You dip the card in the water, and the paper goes differnt colours if there are traces of oil in it.. Migration info. Legacy thread was 139471

POST 9 / ORIGINAL POSTEROriginal post

POST 13Original post

They did the inspection on my tt I was pretty impressed, got PPI by e mail the day I booked it, a telephone report telling me there were no major issues followed by a written report and a CD of some 70 photos showing all paperwork and differing points on the car. Used them Because Peter Morgan wouldnt travel to where my car was (Wisbech) Migration info. Legacy thread was 139561
