intermediate shaft
There has been much discussion lately on PPBB regarding IMS failure resulting in a expired engine. I know our GT3 motors are based on earlier 911 engines (prior to 996 models except for turbos) but I don't recall if the GT3 engine has a intermediate shaft that can fail as with the 996 and 986 motors.

The gt3 style engine does have an intermediate just not like the 996/997.1 it doesnt go all the way through the block.they are not prone to failing in the same way..... the new motor in the 997.2 truly doesnt have an intermediate shaft.... the two chains are driven off the crank only and a seperate chain drives the oil pump, where as before the oil pump was on the end of the intermediate shaft on the belt drive side.

GT3/TT/GT2 all have the GT1 style motor thats has been around for years and NO IMS issues.
Now the 996,986,997 and 987 are all M96 and M97 motors and are known to have issues with the IMS.
Contact Flat 6 Innovations as they have created a new style IMS for these motors.

So the RMS and IMS issues are unrelated?

To some degree. A portion of "RMS" leaks can also be attributed to the seal that goes around the IMS directly below the RMS. I have even seen some of the leaks in this area require splitting of the engine case to be completely resealed. There have been a couple of updates in what they call the "flange" of the IMS. I have also seen some transmission pulled out only to find the RMS dry but the area around the IMS flange wet with oil. Most places I know of replace both the IMS flange and the RMS if there is an issue, along with even updated engine case bolts in the problem area that have sealant on them now. There are also 2 styles of flanges that CANNOT be mixed up.
