Jcb groundhog 4x4

[Tractorlloyd]

Hello all, ive just completed my forst head gasket on a jcb groundhog 4x4 with the lombardini ldw 1003. The problem is its smoking white (unburnt fuel). Im not sure where to go from here and wondering if someones had a similar experience. Many thanks

White smoke still suggests water getting in ,,are you sure it was only the headgasket

If this helps. Yes the head was skimmed and pressured tested. Its had a new water pump, belt idler and timing belt. New thermostat and ive put a gauge and it isnt pressursing

Check the timing is correct.

You could be a tooth out on the belt

All correct markings line up

If head gasket went ,,it might have a core failure between the cylinders

Would there be a way to test?

Check the oil ,,if its gone milky then you will have water getting into the cylinders which in turn will be getting on top of the piston ,,then as it fires ,you get the white smoke

if water was somehow getting into the oil would that nit cause it to pressurise?

Somebody with more engineering knowledge would know that
