Check the timing belt for correct tension or contamination. The oil and
vacuum pump is driven from the back side of the belt.

Subject: slow pressure buildup [diesel]

Although my diesel runs fine for some years, there is one thing that
keepsing me, and I wasn't able to find any info on it.
After starting the engine, it take regularly quit some time to build up
oil
pressure. Sometimes the light goes off immediatly, sometimes more than
half
a minute before it goes off. Outside temp does not matter, nor does oil
level.
I never have problems once it's running.
The weird thing is that the brakes don't have vacuum as long as the
light is
flashing. Then suddenly there is a slight change in sound from the
engine,
the light goes off and vacuum comes up.

What I do is always wait for the light to go off, sometimes reving a bit
higher
helps.

Any thoughts on what could be the cause? I was thinking the oil-pump,
but that
doesn't explain the vacuum

Thanks
Jaap
