  1. Great advice from everyone. Howard is 100% correct. Taking the tank out is not that daunting a task. At a minimum if it's not rusted it will need a vigorous flush. You WILL also need to change the fuel filter. Don't even think about cutting that corner. Good luck!
  2. Bruce Anderson would tell you (God rest his soul) to trust the dipstick 1st and foremost. Get a feel for what the oil level gauge is showing you when the dipstick reads about halfway between the marks.
  3. DME uses a sensor on the flywheel. They do go bad (or at least the trigger can). Change the fuel filter if it hasn't been done already. Does sound like ignition though.
  4. Paint tag on the drivers side hinge post. A pillar black aluminum plate. Paper/mylar/plastic VIN information on the lock post. May or may not be there if the car has been painted and the door areas painted. There is another number hidden under the dash pad above the ash tray. And another number in crayon or similar under the dash. This was a "control" number that is used if you suspect you have a "cut car". This number can only be verified by the factory. You give them the number and your serial number and they will tell you "yes" or "no". They will not divulge what the correct serial
  5. I think that is reasonable. Used similar technique in the "old cars" that actually had an oil temperature gauge. Preferred to see a drop off in pressure along with a rise in temperature. OT; the Harley Evolution engines didn't like to be twisted until they warmed up. (in fact none of them do) Most base gasket leaks were due to ham fisted "get on it and romp the heck out it" owners. I've always allowed for a gentle warm up period holding rpms to a minimum until I see the pressure gauge drop and judging by the heat in the heads (put a glove hand on them while riding) I know it's warmed u
  6. 1975 911-S (49 State car) "52" US, "53 ROW Beginning '75 only the 911-S was offered in the US along with the Carrera which was ostensibly a tarted up S. Same engine. Good luck!
