After main dealer failed to find a water leak and them fitting new hoses and
thermostat housing I decided to look for it myself. 10mins. later I found
the leak, it is coming from a crack in the cylinder block about 1/2 way up
behind the exhaust manifold where there is some "light webs"in the "Ali"
casting, upon giving it a blast with the pressure wash I found two more!.
With the pressure cap loose and not using Sport mode it is not leaking. The
car has done 130k, main dealer serviced, not been treated unfairly,
has anyone any ideas, (please not radweld and sell) I would contemplate a
new or recon engine, but from where?.
The car is a K 93 plate.
Cheers

I've never seen this either, but from what I've heard there's no fix.
Welding up the cracks cause them to reappear right beside the weld.

Are you sure its cracks or what seem like cracks as a year ago my 940
was leaking like hell what seemed from the water pump but it was the
head gasgit ....when i saw the gasgit there was nothing left of the
corner part of it as it had been eaten away. Volvo say they sell a lot
of head gasgit kits for mine and i assume its a very close engine on
the 960.it took me a while to convince myself it was not the block as it
sure looked like it.
