Thanks Robert. Being a dedicated track car for me, the 944 Cup guys recommended 15W50 mobil. Going to Red Line 75w90 for the tranny. It has 210K miles, second motor. The high banks on the NASCAR tracks gets the oil away from the pickup, so the experienced guys use the heavier oil. And still, I had to replace number 2 bearing already...

Sign me up for the high banks of a NASCAR track! I've had this car at Sebring a couple times for DE with no problems but I'm sure on an extended high banked corner you could probably hurt it. I've heard of the # 2 bearing problems and I had found some info on Clark's Garage on some tricks to prevent the #2 bearing failure. Looks like most of the mods would require the engine to come out and some machine work to be done, accept for the Accusump system. Anyway, you may already know of these tricks but if not, I hope you find the info useful.

I don't know if this will help you or not but there is some really interesting info on this website regarding the Motronic DME.

There is some information on the identification of the DME and lots of technical info. Good luck.

I had a shifter rattle problem on my 944 when I first obtained it that had nothing to do with the balance shafts. The shifter lever itself was just completely worn out. There was a lot of play, and I mean a lot, between the post that the shift linkage hooked into and the linkage itself. I ordered a new shift lever and also installed a Boxter 5 speed shift lever. (the Tequipment pistol grip one in with the arctic silver inlay) and modified the boot to fit the 944 console. Looks great, better shifting (no slop) and no rattle. If you have saggy engine mounts or a out of time balance shaft those will both send vibrations into the drive line that will present in the shifter but don't rule out the shifter itself.

Thanks, that clears it

Well, just a suggestion but Mobil One website suggests 10w-40 Synthetic. I actually use the 15w-40 in my 944 and have for years. I also use the Mobil 1 Synthetic gear oil in the transmission/final drive. Works great. Thousands of miles plus an autocross or two with no problems.
