Hi all,
I recently replaced the water pump on my 2000 disco td5 (really fiddly and awkward job, especially in the cold and rain) after a steadily increasing coolant leak. The water pump was blocked up with 17 years of gunk..
To get to the pump I had to completely remove the housing for the rotor oil filter, undo the standard oil filter, and unscrew the turbo oil feed (to the right of the rotor filter).
Now that I’ve fitted the new pump and reconnected everything, the coolant leak has been replaced by an oil leak!
When the engine is on oil drips down (rather quickly) form somewhere in the vicinity of where I was working (see attached picture), but I simply cannot seem to locate it’s origin.
I’ve stuffed paper towels around all the obvious places (oil filters, turbo feed hose, rotor housing etc), switched engine on, but not my even slightest sign of a leak - meanwhile he oil continues to drip from underneath!
The only possible reason for the leak I can think of (not based on hard understanding but process of elimination) is that I used a replacement bolt (M8x80mm I sourced from screwfix) to secure the rotor housing back in place (it has three bolts connecting it to the engine block).
The leak SEEMS to be coming from behind the rotor housing area, but it’s impossible to tell.
Does anyone know if this is poissible, that maybe the bolts that connect the housing to the engine block could leak oil if loose or something? Or is it likely to be something else? There was no oil leak before I carried out the above work - this is the frustrating thing!! I just can’t think of anything else it might be..
Below: The oil is seeping from this gap, but only when engine I running
Above: you can see the fixing on the rotor housing I used a replacement bolt for (without bolt fixed). The leak seems to becoming from behind this area (in line with where the leak seems to originate from when viewed from underneath, in the top photo).
Any ideas? Anyone.. pleeeeease
Thanks in advance,
Robb
