1990 300CE fuel draining into intake, what would cause this?
I took my car (1990 300CE) to get smog tested, and it failed. They said it was running rich, and gave me a list of parts to replace (all rubber hoses on the engine, injector seals, breather hoses etc). I did all that including an oil change, and when I started draining the oil, I had to quickly put another pan in place before the first one filled up. I got about three gallons of oil (and I assume gasoline) out of the sump. When pulling the throttle body to replace the gasket, I noticed a puddle of gas in the intake manifold below the throttle body. I can only assume gas is leaking into the intake system somehow when it is running, and after the engine is turned off. What would cause this to happen? I am not as familiar with gassers as much as I am with Diesels, so please take it easy on me LOL! Thanks in advance, Rich

Sounds like a plunger seal on the fuel distributor.

How easy is that to replace? Is that part available, or should I just get a used one at a wrecking yard?

Rollguy what engine do you have in the car ?. Is it an M103 ? If 103 it can get in from fuel pressure regulator .But again it can do the same if fuel distributor seals have rotted out . How is it running ?

I think it is an m104. It is a 3.0 six cyl. It seems to run okay, other than a slight flat spot in the acceleration.

Rollguy this is the fuel regulator on your car .Remove the plastic tube and start the car .See if fuel comes out of the regulator.

You can probably check to see if the control piston is leaking with a dental mirror just after shutting the engine off.
If leaking, the part number of the control piston seal ring is A 011 997 71 48. You will also need a A 004 997 06 48 seal between the fuel distributor and housing. The procedure is covered in the FSM under 7.3-1660. It is critical to get the screw plug set to the same depth as before. |

All the part #s that I have been getting (Pelican Parts) have been 104 #s, so I assume it is a 104.

You have a M104.980.
It's an early 104 with KE-Jetronic fuel injection. |
