td5 head shuffle

[rangietragic]

Looks like my 130 has got the dreaded head shuffle.Temp guage shoots up into the red and top hose gets hard.Can i use metallic seal up till i get it fixed or am i wasting my time?Mate used it on his nissan patrol 2.8 and it held for a while.Dont need this just before xmas!:mad::mad:

costs more $$$ if the head warps/cracks.

I would be doing it right the first time.

The head can move far enough for valves to damage the bore.

[rangietragic]

The head can move far enough for valves to damage the bore.Yeah, gone cold on using seal up, even temporaraly.Wait for my tax cheque and get it done properly.Estimates so far $1800 to$3500 if head not damaged,from three land rover repairers.:(

What is the dreaded head shuffle?

[gazk]

Head movement due to expansion/contraction of the alloy head that partially shears off the two plastic locating dowels - normally leads to pressurisation of the cooling system. Fix Requires (as a minimum) a new head gasket, new head bolts and new steel locating dowels.

[Sparkys]

Thanks Gaz, is that only on the TD5?

[nedflanders]

Bollox, never heard of this before, now something else to worry about, as far as the Landie goes I'm a bloody hypercondriac :(

Fix Requires .....and new steel locating dowels.
The steel dowels from later models can't be used on the earliest heads so I made my own for my '99 using the shank of an 8mm drill bit. My Oct 2002 MY03 D2a still had plastic (there's a VIN cut-off) but could have used the steel dowels from the later MY03s.

In my experience, yes they can.

The fact you haven't heard about it before doesn't mean it isn't true !! If you want to ignore the facts go ahead and keep your head in the sand.

[djam1]

Definitely true and I have the bank balance to prove it.
The gurus in the UK say you can use the steel dowels on the earlier engine.
I think they just shorten them slightly to prevent cracks due to expansion

Steady on tiger, I said I hadn't HEARD of it before, NOT that I didn't believe it, stop jumping to conclusions ffs :mad:

I guess that "Bollox" in your original post was a word you made up and you didn't mean:

bollocks
// (say 'boluhks) Colloquial
–plural noun 1. testicles; balls.
2. (construed as singular) rubbish; nonsense.–verb (t) (bollocksed, bollocksing) 3. Also, bollocks up. to bungle.
–interjection 4. a contemptuous exclamation indicating disbelief, dismissal, etc. Also, ballocks, bollicks. [Middle English ballokes, Old English beallucas testicles, ? diminutive of ball1. See -ock]
(Macquarie Dictionary)

Unless of course you use the UrbanDictionary: http://www.urbandictionary.com/define.php'term=bollox

In which case you may want to choose your words more carefully.

Isn't the English language a wonderful thing.

Re: TD5 head worn due to moving?
Hi, All td5 engine cylinder head dowels are superseded to the metal type now so there is no problem using them on 10p or 15p engine.
The rings that you have in your cylinder head sealing face are caused by the head bolts loosing there clamping load over time and allowing the multi layer cylinder head gasket to chatter causing it to bite into the alloy cylinder head.
a quick pressure test and skim should be all that is needed but depending on the amount removed from the cylinder head they may need to recess the valve depths.

So is punctuation, aren't commas a wonderful thing! Try re-reading my original post, take a pause at the comma and stop making yourself look like a **** (look that up in your dick-tionary)

[jo_macaire]

Hi I agree with Nedflanders and this is not a place to ark up for no reason.

I am also in the position of pressurised header tank that then leads to coolant loss etc. The wife at least shut it down before it seized, so my assumption that the head gasket has gone seems correct.

Is there a detailed post re doing this job, I can't find it as yet.
Also any point in re torquing the head bolts? I think I know the answer to that one but you never know.

It is a 99 disco with 330k. just done the injector seals 200 km's ago.

Thanks Jo

I think "Oh bollox" might have been better wording, meaning "Oh no not something else to worry about". By starting the sentence with Bollox gives the impression of this is rubbish. That's how I took it at first. It's hard to tranfer how we speak into text.

Hi, thanks Psimpson7 for the speedy reply-only 9 minutes! that has to be a record for getting the info you actually need.

has some blow by so assume the block/ring region is worn or could head issue cause that?

Is it possible to do engine block rebuild as apparently you can't buy oversized pistons. Is that correct?

Thanks Jo

[Psimpson7]

can I beat 9 minutes!

Original Equipment oversize pistons are available.

+20thou.

Heres another thread I did:

scroll down here for pistons:

[jo_macaire]

I think you might need 7 minutes next time :), missed this question

Q) Is it possible that the leaking head gasket can cause blowby, just wondering if any chance the bottom end is still ok

I haven't looked at the link yet but sounds like you can rebore etc i was told that it can't be done.

Cheers Jo

So are you saying that a 2005 model has the steel dowells and are less prone to shuffling?

:)

Yes you are correct.
