603.xxx engines suffer from leaking pressure valve holder seals in the injection pump. If someone "fixed" a leak from bad o-rings on the top of the pump while doing the head gasket, likely you need to replace the copper seal inside.

Otherwise, could be a bad injector, leaking line, or bad IP, not related to the head gasket change.

Check the injectors for proper seating -- if there is something bubbling up around the threads, replace the seal and re-torque the injector.

Thank you all for answers.

It seems like the timing was a bit off. the engine runs smoother now even for its 600.000 km.

In Norway we have some sick import taxses on cars.

So suv like the g model are rebuilt several times..

this one has a 1984 model frame and body, 1995 interior and drive train.

the frame and body has more than 1 300.000 km on her..

So they are good cars, almost bullet proof....
