2 1/4 diesel copper head gasket Help please

“Once again I approach the font of knowledge "

My Head gasket set has just arrived for my 2 1/4 diesel series, it came from craddocks this week with lots of other ordered goodies. I was surprised to find that the head gasket is made of copper!!! (It’s been a while since I've done a head strip). The old one was a steel asbestos sandwich type; the new one seems thinner will this affect compression, or valve timing? Also do you fit these gaskets dry or use a jointing compound i.e. hylomar blue? I can understand that copper will heat transfer well, and not heat burn but what about sealing oil to water galleries. Amongst the bits supplied with the kit are 4 large flat copper washers aprox 1/2" wide. ,8 1/4" size compressible washers copper and 8 1/4" mild steel again compressible, are they inserts or washers and where do they go? Also with the head bolt torque settings be the same, and do you need to re torque after heat cycle? If you have any knowledge ideas or experience of these gaskets, or have any sugestions for my questions please post...

The make of the head set is BM PARTS, THE PART NUMBER IS br 0922, rovno STC15464 decoke engine set 2.25 diesel supplied by craddocks...

Thanks Cartman690...

Help Please...
If you have any ideas they would be most welcome...

When i did my 2.25 petrol last year that came with a copper head gasket. No jointing compound is required i remember correctly.

The haynes manual will earn it's money for this job.

Weigh in the copper gasket and get hold of a steel/asbestos one,the copper ones are cr-p and lead to the pre chambers working loose and chopping holes in the face of the block.

Panic don't know what to do now, sounds like you’ve had a bad experience tell us about it then... ...

Had to bin a couple of 2 1/4 blocks years ago for this reason - sorry,but I thought everyone knew,plus if you buy a genuine gasket from Fews,( not Hunters,dont think they know what a 2 1/4 is ! ) you get the steel backed one.
Only saw your post by chance,it set the alarms ringing.

never heard of that one either.

eightinav hunters and fews you in bristol then thanks for the advice sounds like for a extra few squids you may have saved me a nightmare cheers chap...

Hi Cartman 4 large copper washers are for between injectors and cylinder head. other 8 are for banjo bolts on top of injectors.-----BB
