various questions

been enjoying my 944 for almost 3 weeks now with no problems, until yesterday when i found a puddle of water under the car.

the water hose (94410624103) that goes from the water pump to the heater pipe is cracked at one end.. previously my mechanic said that my car needs a head gasket job, and that carbon monoxide is entering the cooling system and causing over pressure, i found that odd since there were no symptoms of a blown head gasket, so i started my own diagnosis and found out that the previous owner has hard wired the fans to the A/C switch and fans only work when A/C is on! i was always testing the car when the AC was off!

anyways, thought that was the end of the problem until i saw the cracked pipe yesterday, so really dunno if it's the head gasket or not.

i also have the below symptoms and would appreciate if anyone has feedback on them:

1- my window relay (94461511202) is emitting sparkling & crackling sounds at times, heard it when the car was off and keys removed from ignition. what's happening in there!?!

2 - every time i fill the car up a strong smell of Gas fills the cabin, i open the hood and check for any sign of leakage from the fuel lines, fuel filter, but nothing smells or is evident under the hood, i assume it's the fuel line from the tank to the front, anyone has diagrams of these fuel lines?

3- Gas Gauge movement is very limited and never goes up to the max or down to the max.

4- when the car starts the car idles at around 1,000 RPM, when the car is driven for a while and i put it into P or N the idle rises all the way to 1,200 RPM and stays there... it just idles very high. what are the normal Idle RPMs and is there a quick fix for this?

5- there's a leak coming from the back side of the engine toward the top, so basically somewhere under where the battery sits, i can't seem to pin it down as i cant see into that area, i will probably have to remove the DME.anyone has suggestions as to what it can be? shaft seal was replaced 5 months ago and leak is surely not coming from there.

Many Thanks,

Nehme

1- No idea why it's making noises. I would first replace the relay and be sure the window switches aren't staying engaged.

2- There was a TSB for leaking rubber hoses at the fuel pressure regulator and dampener. Also a leak in the EVAP system can cause this problem.

3- Replace the fuel level sender.

4- Vacuum leaks are the first thing to check. Repairing the EVAP system might sort the idle speed fault.

5- Camshaft end cap gasket is a common source of engine oil leak at the rear of the engine.
