911 Camshaft fitting Oiling Update

Back in the day before the turn of the last century we didn’t have the internet like it is today with its vast array of information. We were lucky to have a dial up modem to log onto our AOL account! So we couldn’t just click a year and model car and click “Service...

911 Engine Mounting the Compromise

In the past several months I have seen a number of “HOT ROD” 911s all complaining of various abnormal noises. These noises have been described as anything from cam chain noise, to 5th gear noise, to ring and pinion noise. Are all these cars just getting noisier? Are...

911 Twin Pipe Muffler Conversion

One of the best things about a 911 is the sound; it is what draws many people to the model in the first place. Anything that can improve that sound can only add to the personality of the car. This is no recent revelation on my part; companies have been selling...

Stiff Door Handle

In 1974 Porsche updated the interior door treatment on 911s. Along with the new door pocket storage arrangement came new inside door handle linkage. This system seemed to work very well for years of trouble-free service. However, in some cars this linkage can become...

911 ABC’s

Front Oil Cooler Venting for ’74-’89 911s

A popular update for '74-'84 911s is adding a front fender, radiator style oil cooler, as installed in '85-'89 factory 911s. While this cooler does a very good job lowering engine oil temperatures, it has one design flaw. The problem is not in the cooler, but in the...

Headlight Dimmer Switch/Relay repair

It seems for some reason that failures come in groups and this month was no exception. During the first quarter of this year I have been inundated with requests for information and repairs on ‘74-‘89 911 headlight hi/low switch failures. These are commonly known as...

911 Throttle Linkage Repair

Recently, I was performing some extremely overdue service to my 911SC (you know what they say about the cobbler’s kids going without shoes). Before finishing up the service, I checked throttle, clutch and emergency brake linkage. When checking the throttle linkage, I...

911 Rear Sway bar Swap

One of the great design characteristics of early 911s is their infinite design interchangeability. While the cars have evolved gradually over time on the outside, what’s under the skin remained similar enough so that scavengers, such as myself, can find just the right...

Loose Steering Wheel ’74-’89 911s

Your steering wheel seems unusually loose, is it falling off?  Not likely. What is most likely causing the looseness is the deterioration of a small plastic bushing between the steering column and the column bearing. The bushing has deteriorated and crumbled below the...
