Can I ask another general engine swap question please here? The switch from the 85 1/2 engine too the 83 car, I was originally thinking I would just remove the 85 1/2 engine and break it down to a long block status, then replace all of the accessories. Manifolds, injectors, brackets and such from the 83 engine onto the 85 1/2 long block, and running that long block, can that be done?

I believe that the longblocks should be identical between the 1983 and 1985.5 cars. They should be the same for the engines with marking M44/01 through M44/06

If you use all the early car's Motronic sensors and wiring with the later engine, it should work from what I know.

Diagnosing a Noise
 

Folks,

The good news, I have obtained a 3rd 944. It is a red 86 N/A, 120k miles, with Fuchs and sport seats. The body and interior is immaculate, not even the slightest of cracks in the dash.

However I still have deep affection for my 85.5 automatic that has carried me to work for five years or better, at least when she has been up to it. An automatic is somewhat better in rush hour traffic conditions. However she is getting on in the miles (178k) and makes some troubling noises when cold.

The problem is a tapping or knocking noise during warm up that goes away once fully warmed up. The possible causes (from what I have read) could be engine mount, torque tube or flex damper related, engine related such as rod bearing, wrist pin, or lifter, and probably a few other things I haven't even thought of.

I would love to drop it off at my FLPRF (Friendly Local Porsche Repair Facility) for expert diagnosis, but I fear they will see me coming from 100 miles away and will prescribe repairs that don't make economic sense.

How can I get a proper diagnosis of this noise so I can make the right decision on what this car is worth?

Thanks for your time.
