Thread: Now a head gasket

Damn. Thats not good Craig. There is also the possibility of a crack in an exhaust or inlet port however that is actually a much worse scenario 😢😢

yeah hoping it is not that. Any easy way to check there is not a crack?

Head off I'm afraid anyway as there is an interface somewhere between the crankcase and cooling system. Could also be a bore porosity problem as the moisture in the crankcase can enter via the cylinder wall below the level of the piston, which will not cause any hydraulic lock.

I wouldn't overthink this as this can drive you Nuts, Just get the head off and go from there.
Hopefully it is a simple case of a failed head gasket

I feel your pain Craig. Earlier this year doing a routine check in my D1, I found a thin layer of oil sitting on top of the coolant. Enter that sinking feeling.....

My D2a is in the workshop now with problems with the head gaskets.

Thanks Justin. Yeah head has too come off regardless, next break maybe.
I would assume a crack would be pretty easy to see?
Gasket may or may not show tell tale signs, that is an issue as not always clear.
How would you determine a porous head??
If a head what are the better options?
I see Turner Engineering have them for around 1125 GBP ready to go.
There gos the rest of my tax return if the case.

The only aftermarket I can seem to find are AMC, with Island 4x4 so far the cheapest at $1000 GBP with valves ready to go. Turner Engineering 1125 GBP (app $1925 AUD). SMS Diesel Australia $3300 AUD.
After some info on AMC heads if I have to go this path or other options if i need to. Waiting for a price from TRS.
Likely I will source from the UK as prices here just ridiculous.

Craig, I went through a local Indie and got an AMC head. It should last longer than the original. Good luck!
