Engine Oil

Model: 911, Year:1985, Mileage:148K, Type of use:Street use only
I just had my engine oil changed and the mechanic overfilled it. When driving the motor started to miss and sputter. I drove the car approximately 25 miles then decided to look to see if something was obvious. I checked the oil and found the reading on the stick was about 1" over the full line. Do you think there is damage or just fouled plugs? Should I do something other than draining the oil and replacing the plugs.

Gulp Valve aka Aux Air Valve?

Model: 911, Year:1977, Mileage:72000, Type of use:Street use only
Hi again,Is the Gulp Valve the same as the Auxiliary Air Valve ($$)? As far as doing a quick bench test. Should air be able pass though the valve? If so, I'm buying a new valve.

Hi Chris,Thanks again for getting back to me. I was looking at the Aux Air Regulator. I realized later what you were talking about. But it's looking like a blown air box (darn). I just dropped the motor and will be addressing a couple oil leaks while it's out.Thank again

Gulp Valve Update

Model: 911, Year:1977, Mileage:72000, Type of use:Street use only
Hi Chris,I answered my own question I posted earlier. The brn wire is ground. My valve closes when I do a bench test, but I'm able to blow air through the valve when it's close. Any thoughts?I did plug the hose from the gulp valve to my air box. My vacuum readings look good. But with the valve plug, the engine wont run but a few seconds. Thanks

Engine stops at low RPM

Model: 911SC, Year:1980, Mileage:67,000, Type of use:Street use only
Engine starts fine and car runs well when cold but after it warms up it begins to backfire, runs rough and stops at a low rpm: then it will not start until it cools again. I also have a problem with a start on hot days when it takes considerable cranking to achieve a start (the fuel check valve has been replaced). Could these problems be related? The engine rough-running at low rpm is a new problem.

Flame Thrower

Model: 911 sc, Year:1980, Mileage:123,00, Type of use:Both Street & Track
My '80 SC has been back dated with Webers and SSI heat exchangers w/BB 2x2. Timing advanced and the distributor has been recurved. The carbs are balanced and the car is well tuned. Have tremendous throttle response. I ran a recent DE event at Watkins Glen and received comments about flames blowing out the exhaust. This happens is on deceleration following full throttle down a straight. Is this a common occurance with the carbs or is there an underlying problem I should look into? Thanks, Jim

1984 911 Idle Oscellating

Model: 911, Year:1984, Mileage:40,000, Type of use:Street use only
My 1984 911 idle oscellates up and down every so often. Seems more when it is warm, but will do this cold also. Runs great other than that. 40,000 miles. Any suggestions? thx very much.

Stating Problem

Model: 911SC, Year:1980, Mileage:64,000, Type of use:Street use only
I have added a new fuel pump check valve to correct what appears to be a 'vapor lock' starting problem but it didn't help. The engine will start after some 30 sec. of 'cranking'. Any suggestions?
