Oil leak at fuel pump

[andrew honychurch]

Fantastic, what a great wealth of knowledge there is out there. Its as good as having you all here inthe workshop with me, but without out me having to crack the tinnies!

No seriously , thanks a lot all of you, there are some really interesting points here.

I have to assume, maybe wrongly, that what I have is how it is meant to be on my vehicle. I cannot id the oil pump fitted to mine, as I have not an indpeth knowledge of what the other types look like, but as my vehicle is June 1944 and has the thermostatically controlled valves in the oil coolers , it seems that there may have been a change to the way the system is plumbed.

At present , my best guess is that I have the correct set up but a blocked or restricted cooler. Remember, that during my first tests and run to War and Peace the cooler was getting hot, i.e working. Now it is not. I reckon therefore that the restricition is opening the relief valve and that is whay we are seeing too much oil being fed back through the filler neck.

Much as I didnt want to do it, as its a pain in the arse job, it seems I will need to pull the cooler off and clean it once more with solvent to try to get it flowing ..

Given the low pressures on these engines, its seems logical that it would not need much of a restriction in the cooler or lines to cause the PCV to operate?

David, on the oil greaser, did you have a flexible pipe inside leading from this to the thrust bearing? If not, dont fit the greaser or it will dump into the bellhousing!!

I hope to report back later chaps, many thanks Andrew
