[Engine] Fuel tank half full, revving highly on its own.
#1
Hi.
I have 98 1.9diesel berlingo (800), with 110000 miles, i seem to be having a problem when the diesel tank reaches half empty the engine acts strange the revs jump very high on their own also there is a lot of blue smoke till finally the van stalls like it ran out of diesel. I would aprriciate any help on fixing this problem as it is very frustrating.
Yours kindly,
Frustrated Berlingo driver.:brickwall:

Sounds like it's running on its own oil to be honest, has it always done it or is it a new feature?

Used to happen a lot years ago with diesel engines. Eventually they fix themselves, they rev and rev until all remaining oil is drawn from the sump and the engine then seizes up...

Could this be a blocked fuel tank vent? which would cause a vacuum in the tank.

I would not run with the cap off, just open then replace it at the end of each day.
