OK, this is strange. Driving home last night, my '99 9-5 (2.3 Litre LPT) stumbled and died. Made my way to the side of the interstate, tried to re- start, no joy. Long story short, the hose from the valve cover (under that black plastic shield around the oil fill/dipstick), down to wherever it ends up (throttle area?) has _dissolved_ or _melted_ right up at the top bend nearest the valve cover. Additionally, there is a check-valve going off towards the left side of the car (to the right as viewed from in front of the car) which has also melted/dissolved/become more than one piece. It's a 6mm or so hose, on the far end of the checkvalve from where the hose goes into the valve cover, and has a larger hose around it as a sheath. I don't know where the other end goes.
So, here are my questions:
- WTF happened that would cause this?
- Other than new hoses, what else should I be concerned about?
- Any clues as to why something like this would happen (see #1 I guess)
- Has this happened to anyone else?
The plan currently is to get the hoses I need, install them, and see what happens, but I'd like to understand why this happened. This does, however, explain the "honking" or "moaning" noise I was hearing when I first started up in the mornings; I thought it was the ABS pump kicking in or something; I'm guessing now taht it was that hose, being split, allowing air through it and making the noise.
Suggestions/ideas/advice/whatever please? Dave Hinz
