Is the "sump" your oil pan?
Do you have a manifold flame heater on the engine?

And is the FDC still connected?

Not following you. I'm lost in translation.

Fuel Density Compensator, part of the injection system on most M35A2s. It sometimes leaks into the "sump." Most are bypassed for this reason without ill effects.

Call me crazy, but I would love to tune into the BBC channel sometime and watch Jeremy Clarkson, Richard Hammond, and James May do a proper Top Gear Review of the M35A2.

Rubbish!

Edit: Post pics of your injection pump so we can get a better look.

I would disconnect and plug the supply line to the manifold flame heater. This will easily eliminate one possible source for oil contamination.

Pauline, Welcome to SteelSoldiers. I spent about 2 years living in your part of the UK when I was with the USAF at RAF Upper Heyford back in the early 90's.

Do a search site search for "bypass+FDC" and "manifold+heater" and you'll get some insite as to why some guys bypass and remove that stuff.

Another culprit could be the HH. Definately start with the easier to get to items like the manifold heater.

 

[drgreg]

I agree it's most likely the FDC, but eliminate the other stuff first. I don't think bypassing the FDC would be bad, in any case.

A leaky flame heater will put fuel into the intake manifold (which can also be bad), but has no connection with the oil pan...
