Timing Belt for 924S

[JonA]

I spent a hour or so with the new 87/924 today, it is in remarkably good shape. The 82 924 that we had needed major work to brake and fuel lines under the car due to rust. This car has no rust at all to the lines, the front end is tight, brakes are good, new radiator, no lubricant leaks except at the valve cover, engine runs strong. little growling at the rear at highway speed that I gotta look into. I'm feeling pretty good about this purchase.
Two questions: What is the tensioning tool that is needed to replace the timing/balance belts? How expensive and where is it available? And is it likely that the motor mounts are bad at 90,000 miles? The engine shakes a little at idle and I recall having to replace the mounts on the 82 and it made a major difference.
This baby will be on the street in a few weeks, it's not gonna take much to make it roadworthy.

Thx,
Jon

First and foremost; this is NOT an early 924!!!

Outwardly looks the same but has the early 944 front steel A-arms and the later aluminum rear trailing arms. A much better design engine and Bosch electronic injection.

Might be a rear bearing or the trans depending on how hard it was driven.

You might want to check the passenger floor area for moisture after washing the car or driving in the rain. This is an indication of a hole under the battery. One of the few places these cars will rust as they are zinc plated before they are painted.

Could have colapsed engine mounts. Should be a good inch between the bottom of the pan and the cross member. If it looks like you can't even get your fingers between them then the engine mounts should be replaced.

There is also the Kriket belt tension too. Do a search.

The porsche tool p9201 is what is needed, but is insanely expensive. There kriket tool is much much cheaper and just as reliable, as is the 90 degree twist method with no tool, but unless you have not done a few belts to know how they should feel, then I would use a kriket.

Engine mounts definetly could be bad as mentioned above.

I respectfully disagree with Karl about the repeatibility of the Kriket tool, but then I have the right tool and an educated thumb, and set the tension by thumb and check it with the tool. I'm right about 90 percent of the time.

Incidentally, my thumb and P9201 are available for rent!

I have found with the 9201, you can get 3 different readings 3 different times, without changing the belt tension as well, which leads me to believe that the kricket is just as accurate or inaccurate. I also have the 9201. I have used the 90 degree for years now. Porsche overengineering.
