    Nooooooooo! we've just been through EI with those, they're much more service unfriendly/more expensive than a Tdi

    Bloody hell. I was just going to PM JC, then thought others may be interested in the question and response.

    Ditto.
    And I value the advice of someone with lot's of TDI experience rather than heresay. It's not that big of a job, so if it's a likely failpoint at a likely mileage then I'll be treating mine to said 'preventative maintenance' when the time comes. No big deal.
    Mind you, how many of these total failures had any type of low coolant alarm fitted? As has already been said, was it the chicken or the egg?

    exactly. It's only a pushrod engine, so as simple as they come.

    I'm a bit out of practice, (ok, a LOT ) but have done a complete head change on an engine sitting on a dyno in under half an hour, from shut down after a power run to the next power run on a new head.
    If/when I do the Tdi one, it'll be an all dayer at the rate I work now

    I may be totally off the paddock, but aren't most of these dramas actually caused by overheating, which is more the result of a problem as opposed to the cause?

    Little dramas like thermostats failing and causing overheating, hoses blowing due to having too much oil leaking on them, radiators being blocked causing temp increases which then balloons hoses into bursting, and anything else that actually gets the engine hot enough to blow that all important gasket and the detemper the cylinder head alloy?

    I didn't think the gaskets just blew and/or the heads just lost their hardness because they reached a certain mileage? Or do they.........

    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....

    of course you get the same deal on the head so then its a case of did the head take out the gasket or did the gasket take out the head?

    Mine carcked it at ~40k. Over-heated on the Hume Highway near Gundagai .....rebuilt the motor at some expense.

    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.
