change head gasket on Tdi @ 240k as a preventative ?

Maybe it's worth checking the headbolt tension when adjusting valves?

Nope, leave well alone as they are angle (stretch) tensioned.

I was told that the motor was probably assembled at 4:55 pm on Friday afternoon and that the head hadn't been tightened down properly in the first place...

Who knows the truth of it?

Any way she's still going.

that seemed to happen to a LOT of '94-95 engines.
It really undid the 300tdi reputation before the timing belt thing destroyed it.

from Blknight
"the fire rings that form part of the gasket have a limited life, the harder you work the engine the shorter the life, then you have the monday wednesday and friday arvo versions of the gasket...."

Has anyone used the all metal 300 tdi gasket. they equate to a 3 hole gasket and are as suggested all steel. The lrover guy I get parts off has fitted upwards of 50 with good results, this is what I have bolted in just recently???? Any opinions?

in theory all metal gaskets work fine(they used to when all we had was cast iron blocks) but they can suffer from electrolysis and corrosion from the coolant jacket side...

In my experience they dont give a lot of warning when they are about to let go but thats not much when you really need to be on the ball to pick up the early signs of a composite gasket letting go.

Hmm, is there a better grade of gasket, or are they all prone to fire ring failure?

And I reckon that fuel pump tweak I was thinking of just died........
