Fitzy, yes i did 2 things different, one i took the studs out and rubbed the
block with emery cloth on a sanding block, having put greasy rags in all the
holes. 2) I used a Payen Gasket.It cost £10 but its perfect, torque all way
round half the final torque then go round again and up to full
torque.......Job done.

Interesting.

They do recommend to torque the head down in 3 steps.

As most gaskets are now mono torque and have a coating over the gasket
which melts and seals both on surfaces, these surfaces should be
spotless and cleaned off with a solvent (thinners) to to remove any oil
and grease.

If the gasket is not a mono torque then what is used is Hylomar to coat
the surface of the gasket.

OK I did 5) and it was no good.
Went to the shop and got a Payen gasket.
Spent 4 hrs this afternoon doing it in the rain.........all perfect now
All ready for a trip to Malvern in the morning!!!!!
Cheers

Keith, Thanks for the detail. I'm good down to 5), will do this this
morning. Finished it late last night, warmed it up and there is some
seepage. Hopefully the re torque this morning will sort it. Thanks again

Stupid question but here goes. Which way up does it go? Copper face up
or
down? Cant seem to get it to seal. head has been re faced
Any thoughts?

Hi, Martin,
It's been a while since I fitted a head gasket, but I seem to remember
that
you can only fit it one way. If you look at the front end (radiator
end) of
the block you will see the oil feed hole for the rocker shaft. Make
sure
that this hole is not covered when the gasket is in place.
If the gasket will not seal, 1) do not use any kind of gasket sealer.
2) Check that the tops of the
threads in the block are not raised up. If they are, clean them up
with a countersink bit.
3) make sure that you tighten
the
studs in the correct order, basically working outwards from
the centre.
4) If you have a torque wrench
set
it to 30 lb/ft and tighten, then reset it to 50lb/ft and retighten.
5)After warming the engine up,
re-check the torque of the nuts.

If these tips do not help, you must have some distortion problem
somewhere,
either in the head or the block face.

Martin,
I had a similar problem last month. The head had been faced off, and the
block showed less than 2 thou of distortion in the centre. But gaskets blew
across bores 2 and 3 in less than 50 miles. I read up everything I could
(and there is some conflicting advice out there...) and decided on one last
course of action before a potential block strip for re-facing. I did the
usual surgical cleaning of the faces. I got the latest version of the
standard 1300 Payen head gasket (BK450/TAM1521). This is marked with either
TOP or FRONT (water pump end) to make sure it goes on the right way round
(there seems to be two oil holes now, so it is possible to fit it either
way, but I believe only one way is right). I also bought a new set of
standard studs, nuts and washers. I ran the nuts onto the threads first to
check there was no tightness, and installed the studs with the usual
precautions. With the head faces dry and clean, but a smear of thread lube
on the top of the studs, I torqued it down first to 25 ft lbs. In roughly 5
ft lb increments, I took it down to a final figure of 45 ft lbs. With about
200 miles under its belt, all seems fine so far. I checked the valve
clearances again and the compression pressures at the weekend. This engine
only produced about 140 psi, so I'm hoping it will be alright now. If I had
been running a higher compession ratio, I would have gone for MiniSpares
HS11 or ARP studs, and a GEG300/AF460 or even a C-AHT188 head gasket, but
those bits are serious money (for my pocket)! If the worst happens in the
near future, I'll let you know. I hope this has been useful and that yours
has settled down now too.
