fuel pump housing only has relatively small pressure ,but poorly injectors can fill sump eventually

Think he is looking at a new FIP to be honest. The old DPA pumps (first rotary pumps) use to do this on a regular basis.

excess goes past rings over time ,often burns piston ,had it with a 3.5 efi x 3 on same car ,too but would think of checking pump first

Errrr, how about the lift pump seal going?
or am I wrong here?
sure I had a lift pump pushing derv into the sump the other year...
mind you, on giving it more thought, as it was leaking, i blocked the vent hole till new lift pump arrived..
so own goal perhaps eh..

lift pump has no seal ,but on tdi and earlier models diaphragm could easily add diesel to sump

To be honest, looking again at your first post you may have popped a head gasket.

Twas my 1st thought anorl but wasn't going to 2nd guess you and JM
Well he said there was diesel in the oil, that can only come from one source in any great quantity. It certainly sounds like the crank case has pressurised, either by being filled with diesel or combustion gases. So it could be either really we will have to wait and see. Whatever it is it sounds like something has gone pretty terminal. If there is indeed diesel in sump would still go for pump seal, with head gasket second.

A duff injector pouring fuel into a cylinder can lead to some pretty dramatic effects if the engine is running at speed, like bust rings/piston and a fair amount of diesel in the sump.

The amount of diesel injected at any time is minute, fuel can only be delivered to that injector when the delivery valve is open to it once per cycle. Yes the piston can hydraulic and snap the ring lands but that will only happen usually with coolant ingress. A massive amount of fuel would be needed to be introduced in one cycle to do that. The injector pump is simply not capable of delivering that amount of fuel in one cycle before the exhaust valve opens and it is ejected. The engine would have to be run for a considerable time in that state to show any rise in sump content. Unless the sumps extra content is coolant.

Thanks guys, just a waiting game now. Did these have a facelift at any point? Cheers.
