I have an '84 Lincoln with the BMW 2.4L diesel engine. The Bosch injection pump leaks. Does anyone know what model pump this would be, or know what might be the cause of the leak?
I can tell you that the leak is usually at the timing
advance cover on the lower drivers side of the IP near the front. It
has two 25 torx bolts holding it on. You should be able to remove the
cover without removing the pump on a 524td (spring and 2 washers
inside). IP has to be removed on a Lincoln. It has a square o ring
seal. The right side can leak but not as common and IP must be
removed. The IP head o ring will sometimes leak too and can be
changed without full dissassembly if you are carefull.
You should be able to clean it good with something like purple stuff,
engine cleaner or carb cleaner. Dry it off, crank it up and look with
a mirror to determine where it is leaking. Or hold a clean rag under
it and look at the rag for fuel spots.
If it leaks bad cold and slows when warm it is the timing advance
cover.

If you want a Kit, Bosch has a DGK 121 Kit that has almost everything
but the front seal and it has the WRONG TOP COVER gasket. DO NOT use
the top cover gasket with this kit. It will break the cover! The kit
includes brass washers and small o rings.
Bosch also has a DGK 126 kit that I think has the right top cover but
the front seal is wrong on this one too.
