Symptoms = thrashing noise (like tree branches wrapped around the axle) and all the oil just poured out the car like a spigot. What are the RMS and IMS failures and which am I likely to have? Any tips on getting Porsche to replace the engine AGAIN (it's not under warranty now). I don't trust the dealer garage; it's with another mechanic for diagnosis now. Love my car, but this is too much!

I can suggest shops in So. CA where is your car?
