We have a KJ 2.8crd extreme sport. For about last 3 years it has used water, needing about 0.5 litre once per month. No sign of an external leak, and no other symptom. This gradually was getting worse so decided to have it looked at by usual garage. They found no 2 cylinder lost pressure = head gasket. Head was taken off, it did need skimming which was done and crack tested which was OK. Garage built back up, pressure tested all 4 cylinders and all looked good. However after driving 20 miles water light came on and needed top up. Over next few miles it got worse till now it needs top up every 5 miles!
Any advise welcome - head is cracked? gasket still? or cylinder liner?

I'd toss it back at the garage and tell them to sort it

get it back ASAP

Yep, back at garage.

They have not got something right.

Its back at garage today.
As the head has been skimmed which gauge head gasket should be used: Same as original or different?
This may be a stupid question but I'll ask anyway: Does the head gasket sit on top of the cylinder liners and hold them down, or do the liners protrude through the gasket and mate up to the cylinder head ?
Hence my first question about the gauge of the gasket.

I seem to recall reading somewhere that after any head work, a different gasket is required..I may be wrong, but I don't think I am.

gasket sits on top of the liners. You need a thicker gasket if you machine the deck or fit new liners IIRC, BUT how much did they skim the head? Were the liners checked? Wonder if the top of one is not flat. Going to be a head off check though

so many jokes ..... so little time

  Guess I left myself wide open with that one.

The head gaskets come in different thicknesses to compensate for head skim, but wouldn't cause your water problem.

I think they A missed somthing rebuilding it B dye checked for cracks not presure checked
