I know water pours into the engine compartment of these turbos during hard rains. Mine engine squeaks (right rear) like a belt whine after intense rain, but generally will go away. This last hard rain, the chirp on deacceleration will not go away.

Anyone else have a problem like this?? I guess if it is not common, it could be a pulley.

Strange Porsche hasn't found a way to redirect rain water away from the engine. I learned early on to put a towel over the engine fins to avoid power steering problems when starting the engine after washing the tt.

 

Yes, my pwr steering is affected too in the rain, strangely aerokit cars are immune.

 

Very normal.

 

Are you saying no belt chirps or squealing??

 

I would think "normal" if the squeak/chirp would eventually go away. But if it persists, hard for me to accept simply a fan/pulley belt. I guess I could try some fan belt lubricant...if it stays, it must be a pulley screaming for proper lub or whatever.

 

The belts get wet and dry off with a few rotations . More water gets in and it squeals again . If you are on a highway in a downpour it won't squeal once moving . The 997S did too . I had two of them . all three cars squealed. It does rain hard in Florida .
