RMS

Model: 911 3.2 cp, Year:1986, Mileage:107000, Type of use:Street use only
Do the watercooled turbo engines have the same RMS and intermediate shaft problems as do the normally aspirated powerplants? Have been looking at purchasing one of the early watercooleds and was wondering what sort of upgrading I would need to consider before making such a purchase.

Difference between 3.6 and 3.3 turbos

Model: 356C, Year:1963, Mileage:45,000, Type of use:Street use only
Hello,I am interested to buy a 1991-1994 turbo. Could you tell me the main differences between the 94 3.6 and 91-93 3.3 cars. Although I would like the 3.6, I am not sure it is worth the extra money, particularly if I plan to do some engine mondifications, etc. Please let me know your advise.Regards,Chris

OIL 2001 996TT

Model: 996TT, Year:2001, Mileage:12,990, Type of use:Street use only
I got an oil change last month at 12,000 miles now I have 12,990 and I noticed on my receipt that my shop used Mobil1 10-30W. I called the owner of the shop and says he uses that weight here in Phoenix AZ during winter months. I also called the Porsche dealership and the Service Adviser said this is OK to use as well? Should I be concerned that this 10-30W is to light for my 996 Turbo or should I have them redo it with 0-40W?

01 996 turbo boost pressure?

Model: 996 turbo, Year:2001, Mileage:40000, Type of use:Street use only
Saw 1.0 bar recently on this car (new to me); and after reading here and there, find 0.7 to 0.8 bar to be typical stock pressures. Up until now, I had understood this car to be stock. Might the ECU have been changed, or does this indicate some kind of failure? PPI at a dealer a few weeks ago did not turn up any overpressure warnings/codes. I'm still waiting to receive my maint/svc manual so can't research that yet. tnx jim!

Oil change frequency

Model: 996 tt, Year:2002, Mileage:18000, Type of use:Street use only
The last oil change was in March this year. Since then the car has been driven approximately 1,000 miles. I use AMSOIL 5W-40 European Engine Oil. How frequently should the oil be changed based on time versus mileage.

Help or ideas for an engine area noise

oil pressure gauge

Model: 930, Year:1986, Mileage:60,900, Type of use:Street use only
Just replaced my fan belt as it was starting to fray. I noticed it when I was prepping my car for the start of driving season (Palm Springs). When I started it up the oil pressure gauge started up at mid-level and topped out with any pressure on the gas pedal. Could this possibly be a problem with sticking during the summer when it wasn't being used (just started and backed up once a month)? I'm thinking just a gauge gone bad.....your thoughts?Thanks,Ken S
