thick h/gaskets

[axsaxoman]

they were not available+i was told that due to age there would be no more by the OE maker --but now back in stock at sensible price
+0.4mm =£48 inc vat

[Synister]

Can you get hold of a genuine TU2 gasket?

[axsaxoman]

please be more specific--tu2 --you mean 1294cc pug rallye or ax sport engine
which is fire rings and kevlar --not mls

[Synister]

I forgot about the carb'd TU2's, sorry.

TU2J2, 1294CC, 1996 106 Rallyé.

[axsaxoman]

we used to use the axgti on our 1294cc tu --cos it had a little kink in it the round fire ring to allow larger inlet valve usage

only ever bought 1 cit sport up rated one --over£100 in 1991+ never had gasket problems with that engine anyway
why? you having problems with h/gaskets
any 1360 h/gasket should be fine --unless you got bigger inlet valves in it or there is another problem --like liner seals or corrosion where the liner fit in the block.making seals leak, due to antifreeze not being changed often enough

Suitable for the 1600s John?

I don't need one now but it's good to know you have them.

[axsaxoman]

yep stock all 4 sizes of mls gaskets for cast iron block engines

That's great to hear about the 1360 hg John, thanks.

A genuine 1.4 XSI gasket is £19, a genuine 1294 gasket is £79.

My engine has 123k miles on it and a previous owner fitted a 'Superchip' to the ECU which made it overfuel and also removed the rev limiter. I'm guessing this is why my car is showing the signs of a blown headgasket. I have since replaced the ECU with a standard rallye one.

The reasoning behind me thinking my Hg is gone is the colour of my coolant and all the gunk in it that smells like fuel/oil...

[axsaxoman]

yep looks like it to me -- but question is why ? --old age or lack of coolant changes ?
if no water in oil ,then its not liner seals .
replace rad cap +thermostat at same time --could even be cap not holding pressure and allowed temp to climb +boil in head at some point
do not let liners move up when head off --lock crank --if they do then you will need to change liner seals

only way toclean all that oily crap out correctly is after rebuild do not fill with coolant -- but stick a tin of gunk in with the water run till warm =drain
as you drain water to do head that crap will stick to rad core =block etc
then refill with just water warm yp again and check no more crap --then drain and refill with coolant --red type good for 5 years at least

[Synister]

No water in the oil at all. The engine is on 123k but the previous owner said he replaced the head gasket @ 121k miles (3 years ago)

I'm good with service intervals and regularly replace fluids every 6-8 months, even if the car has only covered a couple of hundred miles in that time.

Believe it or not, that's a new cap and a new thermostat & housing. I've put radiator cleaner in it and flushed it about half a dozen times. I've even bought a new radiator but don't want to fit it until I sort this sludge problem.

Thanks for all the advice John, you're invaluable to this forum.

[welshpug]

has it still got the heat exchanger?

[axsaxoman]

good point welshpug --
but I thought it was only saxo vts that had the heat exchanger on the oil filter

seen a couple of those leak internally and give impression h/gasket was gone

[Synister]

It has indeed still got the heat exchanger. Strangely enough a friend mentioned that the other day. It looks a bit battered to be honest. I've tried googling for a replacement part, searched the part number from Servicebox and searched ebay but I can't find a replacement.

If I take it off does it leave the screw in bit for the oil filter on the block? Or do I have to buy one of those from a car without the heat exchanger to get the oil fiter to attach to the block?

[axsaxoman]

you can test first before removal --link out the hoses with a bit of 15mm water pipe --and see if you get oil coming from the unit

to remove -replace long adaptor with short std screwed bit from any saxo or tu series engine --then refit oil filter

[Synister]

You mean to link the two pipes coming off the top radiator hose? I'll do that tonight.

[axsaxoman]

yep link them out so they don,t pass through the heat exchanger

[Synister]

Thanks again. I'll do that tonight whilst the missus is out, hopefully that's the issue and I can just do away with the heat exchanger.

[welshpug]

its a sport chassis thing, tu2j2 and 3 and 5j2.

I've found that a bottle of Holts speedflush and a couple of dish washer tablets (with the power ball cleaner bit removed) crumbled in the old coolant will flush out that oil. Done it loads of times on Rover K-series engines which have a penchant for HGF and filling the cooling system with oily mess and they've always ran clean after a flush. That said also a garden hose adaptor for your hot tap is worth it when flushing providing it'll reach to where you are performing the operation

[axsaxoman]

never thought of dishwasher tablets--just old fashioned --but yes that sounds like winner-dishwashers run at low temp so running up engine temp should really get them fizzing
