Hi

Diesel is contaminating the engine oil while engine is running from max on the dip stick to half way up the dip stick in 5 miles

There is no lift pump on the engine

There is no oil feed to the pump as it is a rotary pump not a in-line pump

There is no cold start injector in the inlet manifold

I have already had new nozzles in all injectors

I am completely baffled by this never seen anything like it in 14 years

Please if anyone has got any ideas I am pulling my hair out

Thanks

Adam
