They don't make those copper gaskets like they used to. :x
ACL's 998 gasket is the best one about now for all smallbores. Has a 100,000 warranty too.:)
I'd deck the head while off, to ensure it's flat. Check the block also.

Something's badly wrong there for a gasket to fail like that - maybe incorrect head torque or studs stretching, warped head or block surface.

I only use the genuine Rover TAM2121B head gaskets on small-bores these days.

ACL's CP250MT gasket is Aussie, maaaaate- similar construction design to the BK450 (1275)gasket but with a blue water seal bead round it and all the water holes.
VERY hard to blow.
GR uses them too. :wink:

Very easy to get here, unlike the one you quoted.

Available from Repco, AutoPro, AutoOne, AutoBarn, etc.

hehehhe :lol: i think it would ahve been 2 cyl's? it tried very hard to not run anymore for about 2kms (i was almost home) but when i stopped so did it and i could not get it to go again, about 2 kms from home :S walkable, but much easier to call dad for a tow home :twisted: :twisted: :twisted:

when we had the head off it appeared that it had been recntly machined, i ahve driven it 10,000 kms since july, but it still had all the markings from machining all over it! also all the valves were sitting just a little up out of their seats, indicating that port work has recently been done.

but we checked both head and block anyway, both were dead flat. when we put the shiny new gasket on we thoroughly sprayed it with mylomar (before we put it on :P:P:P) both sides and around every hole la bla bla. connected all thoe hoses up proper and set all the tappets to correct gap (0.012"). have driven it about 150 kms, need to check gaps and tighten down head!
