Delica Canada | Mitsubishi Van Club

I was heading off to camp yesterday, long trip down the 401 highway. About 2 hrs in I noticed my oil pressure dropping. 20 minutes later, the engine made a big knocking noise and started to run away (as in, I lifted my foot off the pedal, and it kept driving down the highway at 100 kph.

Pulled over to diagnose and I found: lots of diesel in the oil, and lots of diesel/oil coming out of the crank case vent hose and into the intake.

Can this be anything other than a failed fuel pump seal?

I can't help with the diagnoses, but I'll be working in Hannon all week so if you need anything from Right Drive I'm sure I could pick it up for you.

If you have diesel in the oil I would go with pump seal.

Unless you lost oil and compression on a cylinder and had diesel leak down that way, but you would have probably noticed the loss of power.

Pump seal is most likely IMO.

Thanks Marco. I'm going to make some calls on Tuesday and see if u can get a rebuilt pump shipped from rising sun or cvi.
