    Is my Block Knackered?

    Gday

    Well

    I've been chasing a ticking noise in the Landy for yonks. One suggestion was a blown head gasket. Between the rear and No. 4 piston allowing pressure to escape

    Well the other day I noticed the ticking sound and a different noise. Upon closer inspection it sounded like an exhaust like, so I thought thats not hard I'll just whack a new manifold gasket in and she'll be fixed.

    Well once again I had a closer look, an low and behold it's not the manifold gasket but the head gasket

    Now to make it worse I'm not sure what the story is here.

    I imagine the top of a block to be smooth, well I ran my finger behind the head to feel the pressure leak. And I found what felt like a crack in the top of the block.

    I poked my head over the back there and sure enough theres a little crevasse in the top of the block and next too it what looked to me like the end of a crack

    If I had a decent camera I'd take a photo of it for you

    What are your thoughts?

    Guess I won't know for sure until I pull the head off

    Hi Jock
    Quite normal to have a "lip" at the top of the pistons travel,the more pronounced the lip is the more worn the block is.
    Im guessing its the lip you are feeling not a crack as such.
    GOODLUCK

    JC here Jock, on Stooges computer... That is a common head gasket failure, and you are looking at the head gasket, NOT the block surface. That is precisely what I was telling you what I thought it was when you were first talking about that ticking noise ages ago.

    Easy to fix, just do it soon before it leaves a gas trail on the head or block surface.

    Right you are JC

    I feel like a doofis now

    I only noticed the head gasket noise recently (Wednesday)

    The gasket must have split all the way causing the noise to become louder

    What do I need to do a head gasket?

    Head gasket, manifold gasket and do I need new head bolts or will they be right to re use?

    Good idea to use new head bolts, for the cost of a set of new bolts it's not worth the risk using the old bolts, Regards Frank.

    Hi Jock,

    Naughty boy! You should know by now to ALWAYS listen to the words of The Master!



    When I made the per-emptive strike on my head gasket earlier this year, under the tuition of The Master, we re-used the original bolts. Important points seem to be:
    • Thoroughly clean old gasket off the block face and blow/wipe all the gunge out of the bores, coolant and oil galleries.
    • Thoroughly clean out the block threaded holes with solvent (contact or carb cleaner spray) and compressed air & clean the bolts well with a wire brush then oil them before putting back in. Make sure the bolts screw in easily and don't 'bottom' on cr*p at the bottom of the holes.
    • Perhaps have the head very lightly skimmed to clean-up any gasket/blow-by marks. Some recommend against this but JC does it, so I did too.
    • The new gasket will come with the details but from memory, nip up all the bolts to 40 or 60 Nm in the correct order. Then two rounds of 60 degree tightening. Ask JC for his 'secret' method for doing the 2x60 deg steps.
    Hope the mods don't see this - but if you're thinking of new injectors while the head's off, you might like to have a squiz in the 'engine parts' ads pages...

    Sounds like you guys have had a bit of rain recently? Lots of playing in the mud, I hope? It's bone dry and dusty up this way, so any rain you can spare would be appreciated. Hope your beast is back in action shortly. Say G'day to all from Annette and me.

    No worries Ian thanks for the hints

    The trouble is this week is going to be a busy week, so I'm not sure I'll get a chance to do it myself

    Might have to get my fella up here to do it

    Yeah we've had heaps of rain, but I haven't really been out anywhere lately
