Hopefully some of you guys can help me with this one...
A few days ago I heard a sound coming from the back of my 996 that I hadn't heard before. At first I thought it was the air filter box leaking (sounded like sucking air) so I ignored it but it's got gradually worse and now sounds more like grinding/scraping metal and it's quite loud.
I kneeled down under the car and it seemed to be coming from underneath in the sump area (oh my god! panic) but i've narrowed it down to the left side, the sound was just resonating through the sump. I phoned a local Porsche specialist who said it could be the water pump failing as this would make the metallic grinding/scraping sound (fingers crossed).
Has anyone else experienced this?
The car runs absolutely perfectly with no smoke and no loss of water or oil so i don't think its engine related although I have noticed the oil pressure gauge starts at maximum in the morning or when cold, then gradually drops to 3-4 but then once nice and warm it can drop to 1 when idle and in between slow gear changes (when the clutch is disengaged basically) is this normal?
It's not under warranty so hopefully it is the water pump and the oil pressure is normal. It's going into the garage in a few days though so I just need your diagnostics before i go.
Thanks!
