Toyota Landcruser 3.0 TD 1993 - Diesel contaminating the engine oil - Fixed #

Posted by Adam Townsend on October 27, 2010, 11:20 pm

Year of Manufacture *: 1993
( Optional ) Engine Code or CC: 3ltr turbo diesel

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

Is the pump chain, gear or belt drive ?

Cheers Aidan

Hello Adam , could the return to the tank or spill pipes from the injectors be on the wrong pipes and somehow getting in the block , have seen a injector spill pipe connected to a vaccum source and the brakes vaccum pump was sucking the diesel into the engine .
Just some thoughts

all spill pipes are correct not to vac pipes
having spoken more in depth with the customer to dat he has told me that the car is a 1998 not a 93 as first thought i have read about a diesel spill control valve relay could this be over preasureing the system in some way

meny thanks Adam
