Help Please for a 1990 90TD
Hi all
I have a 1990 90TD and I am encountering the following problem.
When I drive at speeds in excess of about 45mph for more than a few minutes
(ie speeds when the turbo should be in operation) the car loses all power
and comes to a halt with the engine giving up entirely, I solve this by
undoing the fuel filler cap when pops off like a morter bomb leaving what
fuel is visible bubbling like lemonade. The vehicle runs fine after this.
This is becoming a real pain for all but the very shortest or slowest
journeys. I was told before that there could be a leak in the diaphragm in
the plenum chamber on the injection pump (whatever that is) but it occurs to me that instead of the turbo charging the mixture it is charging the fuel tank instead. I've unblocked the breather tube to the tank and bought a new filler cap (which according the landrover is only vented on the way in anyway). The pressure is building up inside the tank and not creating a vacuum as should be the case.As i can only go a few miles it is hard to tell but it doesn't seem like the turbo is working on the engine either.
Any help would be greatly appreciated. Thanks
