i am just going o sell it i have 6 911's to drive so a total rebuild is not going to happen everything else looks great and seem to run fine other than the leek in the cylinder. the cylinders have a steal/iron sleeve in them so getting a good in spec jug would not be a bad thing. the mud blocking the fins and restricting the air flow in that spot is the only reason for the thing to crack .the leak down test came in around 6 to7% overall...

Bill, Thanks for passing on your experience. I enjoy the heck out of the 912e, however if it gets to a point where it becomes smog challenged beyond what I want to deal with I may part with it. Hopefully that day is long down the road. Both my 928 and 912 are weekend cruisers for fun. The 928 smog emissions are so low, it has results as if it were new? Not bad for a 20 year old car!

Where do I find a copy of a wiring diagram for a `96 912?

I agree on the vacuum leaks. Test one more thing! Look at the air mixture controller, it sits right by the air filter. Behind it is a large electrical plug going into the controller. Start your engine and then see if your engine cuts out if you touch the plug or the wire. Mine had the same problem and I discovered on accident that the plug was nit correctly seated and some of the soldered wires inside the plug got loose and send a bad signal...

well theres your problem!

cali4sun I've seen those FAQ's on the BAR site. I can't dispute them, but what I'm guessing is that the accuracy of measuring has greatly increased to the point where a very slight +/- can be the difference between driving off with your new certificate or contemplating suicide. With one mid-70's Porsche I owned I got caught-up in what they call bouncing, where you fail, then go for your free retest, fail again, go...

well, I have lived in California for about 22 years now and they want old cars off the road so badly its incredibly obvious. They do not make money off of old cars, they make no tax income, very little registration fees and the don't like that they "pollute" more. Keep wishing and dreaming that California politics is all Angels with halos... More like Lucifer in disguise.

Michael, some of the gland nuts that hold the flywheel on are made of a higher strength material, so check with the supplier on the flywheel bolt. I think some may be up around 350 ft lbs to 400.

what is the difference between a narrow lobe cam and a wide lobe cam and what years are they found
