Blown Head Gasket - Land Cruiser, 80 Series

Rebuild for us. The word marked bore comes to mind & dust. Ours 92 with 330 on the clock. went through the elimination process first. Radiator and the list goes on.

in my experience vehicles rarely blow head gaskets - but they often crack heads

petrol or diesal?

Common on this motor at this kms.....i did mine at those kms, and the reason is....alloy head stretches head bolts each heat cycle, and sooner or later they loose tension when cold, and gas starts to leak across when cold...gets worse as gasket errodes....till u start to miss at startup. Thats what happened to mine anyway, 1700 had a reco on the head and new toyota gaskets and head bolts ($35 each)
After me, another went on a mates cruiser (4.5) he bought a gasket and tightened the head back down to spec torque plus an extra 1/4 turn.....its still going. So it depends on whether you overheated at all or just started to notice bubbles....if the later, a new gasket and new bolts (aftermarket are $65 a ser) would do...but that would depend on the valves being in spec for clearance...if they r out, you might aswell get the head service done (350) and another 350 to set the valves whilst all appart, or play with shims when its back together......which is a PITA as you need to buy the shims from Toyota.

Is it running LPG ??? Regards Steve M

Thanks to all for your replies, I'll now wait until I hear from ARB as to the problem, fingers crossed for only a head gasket.

Cheers,
