Valve guides 72,343. Miles


 I purchased a 1996 series 993 cab with the 72,000+ miles from out of state. (California)

The Carfax came back clean and it just passed ny state insp.I don’t know if the valve guides were done but the car runs fantastic and does not smoke or have any oil leaks or trace of blue smoke on start up. Is it possible that the valve guides were already done? With this car with this many miles.? Did all of this series have this issue .  As I am thinking maybe this problem was corrected? 

Any feedback would be most greatly appreciate best regards

1997 C2 993 engine oil

Hi.. I just read your recomendation on using 15W-50 or 20W-50 synthetic oil for  993.  I have always thought that Porsche recomends 0W-40, because iti is used as a hydraulic fluid to pressurize the lifters on startup. Won't the 15W-50, 20W-50 have a problem doing that ?

Some oil leaking from my 993 cs 1998

I just got it. And realized afte being parked for few days that I found oil on the floor and this each time after I parked the car.

The dealer told me it was unusual for this model and year.

Should I worry and stop driving the car until I get an expert inspection?

Porsche Codes

Hello,  I'm getting randow codes recently. The car runs perfect but I'm wondering does anyone know if P0410 / P0411 and 1124 / 1126 have any simularites with regards to a faulty component?  MAF, etc???  Any help would be greatly appreciated.




993 Engine Check Light

I have just joined PCA and know there has been much correspondence in the past regarding the dreaded CEL light.  Every year I dread the smog test and spend money to get a mechanic to "turn off" the light for a few miles of relief only, during which I rush to the smog station.  Many mechanics and dealers and dollars later I am so worn out by this cycle that I am even thinking of selling -- although I can't sell it with the CEL on!  There has never been a problem showing with the diagnostics and they say there is nothing to fix.
