Hi Guys

Sometimes I love this forum, and other times I HATE it. Seems like whenever I read about an issue, I seem to experience it soon after. Forewarned is forearmed or am I attracting bad karma...

So, I smelt hot oil on sunday, but, no drips under the car (except me..). Looks like a small leak around the oil sender unit, however, when I removed the old unit (socket no 24), it was hand tight, so the leak may not be a faulty sender unit, just a loose one. Anyway, replaced with a new unit, part number MC840219 which requires a 27mm long reach socket, which I do not have.

I think Mitsubishi is trying to make it difficult so that one is unable to effect a roadside repair and needs roadside assistance...

Thank you so much for thread! My two week ago purchased 3.2 Did is p**sing oil and I have found the culprit thanks to this thread, it is the sensor indeed. However I think the sensor was replaced shortly before I bought it because it looks fairly new. it is leaking between the black plastic part and the goldish yellowish metal ring part as 4ePikanini mentioned. I will just replace in any case. Just wanted to ask if there is a bush or a washer or something that one has to replace perhaps together with the sensor?? Just find it odd that a sensor that looks new will leak already after two weeks. I can make a video or show photos of the leaking sensor should anyone want to see it, as I was a bit lost at first, still learning my way around the engine I am not a engine fundy...

Any advice or help much appreciated as always!

Hi CharlieM,

If you have not already done so, do yourself a favour and download the workshop manuals from this site (Resources|Downloads|Manuals). The engine lubrication system is described in Chapter 12.

You will see (page 12-7) that there is no bush or sealing washer, but reading on, there is a special thread sealant (CharlieM) to be applied. After installing a new switch with the thread sealant and torqueing up to 12Nm, the car must stand for at least an hour for the sealant to work.

Apart from the inaccessible location, it should not be too difficult for you.

Hi
New switch is now a 26 mm.
