Disco 1, 300tdi water (coolant) leak . . .

Hi all,

(Hope I'm in the right place here ?)

Had a problem with a Series 1 Disco '97 300tdi, water leaking from the rear of the pump housing (front of the block) so likely the P gasket. Stripped everything back, pump and housing removed and changed both gaskets. All cleaned and refitted, and hey presto, still leaking ?!?

Whilst the pump housing was off I checked the front core plug just in case, no evidence of leaking and no obvious faults. I'm at a loss now as for what to do next ?

Any suggestions greatly appreciated, thanks all.

was the housing in good condition , ive seen several were the contact face was eroded

Thanks for coming back. It wasn't too bad. The mating faces were all cleaned, I used a High Lamar (spelled wrong I reckon) sealant on each face to level the surfaces before the gaskets went on / in. I'm wondering if the engine block may have a crack ?

it would be highly unusual for block to be cracked unless a bolt was wound into a hole which was coolant filled, where exactly is the leak , its not running down from a hose etc

Very difficult to say exactly where, especially no I've refitted everything Far as I can see, it's lower than the P Gasket that I just fitted and seems to be just above the bottom of the pump housing, between that and the block ?
