LR 2.5 n/a injection pump leaking
Discussion
Hi all,
My injection pump has developed a bad leak and I cant tell where it coming from (As usual, everything is already wet and oily, so no overly obvious signs).
I've checked the lines and gently tightened all the connectors, but it is still dripping.
Is there a seal or a gasket that needs replacing or is this pretty much a sealed unit? I wonder whether it may have cracked somewhere as the diesel seems to be pi55ing out during a run.
Anyone have any wisdom to share on this.
Also if I wanted to replace it (1984 2.5 n/a ex MOD engine) would a 200 tdi pump be the same or is it specific to the n/a?
Please help as diesel isn't getting any cheaper and I'd rather burn it then admire it on my drive.

Hi Andy,
Normally I find these pumps leak from the throttle lever shaft and pee fuel everywhere!!
If you have a good friendly deisel shop they may sell you the seal seperately. If not you will have to remove your pump and get them to fit the new seal.
I dont think the 200 TDi pump will fit as the belt housing is different from that of a 2.5 n/a engine.
Hope this helps

This is the DPS pump right? If it is its timed with the timing belt.
If you need to get the pump out to do the seal then I'd guess the pulley has to come off and that means
remove fan/belts
remove water pump
remove front crank pulley (big 47mm nut can be a b
h)
remove from timing cover
remove timing belt
remove dps pump pulley (the body of the pump should have timing mark and so should the face its bolted to if not make one. This is separate from the mark on the pulley which I think is keyed to the pump shaft)
remove dps pump
I've just done front crank oil seal for which I had to do most of the above and it would have took probably a day (i'm slow with the spanners) but it snowed about 10 times during the day so kept stopping. I had no problem with the crank pulley nut and it took minutes to get off but my mate spent 3 1/2 hours persuading his to come off
This should give you some light reading
