The car ran fine all summer. Just recently car started running real rich, plugs were horribly fouled, and when checking oil found lots of fuel in crankcase. Fuel regulator problem? The cold start valve has been inop since I have had the car (15 years), just lived without it. Thoughts please..

When I checked the plugs to try and isolate one cylinder, all four plugs are really fouled, so it seams like it is more than just coming from one injector. There is lots of fuel in the crankcase, the oil level on the dipstick rises noticeably. I changed out the oil, and only drive it 2-3 miles, running rich, and I can see the oil level is higher each time.

Bad air flow meter?
The air flap gets bent and drags so it can hang up and add more fuel than needed. But also the fuel pressure regulator can leak and dump fuel into the intake through the vacuum line. Jim |

Jim that sounds like a very good tip re fuel pressure regulator. simple as disconnecting the vacuum hose to see if anything is coming out. |

Does the 1.8 have a cold start valve?
