cracked head ?

[Martinaston]

i've spent all afternoon stripping a 325 head in the assumption that it was cracked or the gasket had gone, but after pulling it all apart the gasket is in great shape and i can't see a thing wrong with the head

So i need some help if you guys can list all the places you know the head crack's so i'm sure i'm not missing anything and waist £45 for a pressure test.

Cheers

They can crack between the water jacket and the combustion chamber which is usually spottable by the excess corrosion in the water jacket. Or they can crack in the camshaft bearing journals. That's all I know.

Right at the bottom of the rearmost two cam bearings is the most common place I've found. Looks like a thin grey line that won't rub or polish off.

Mine was cracked exactly under the cam 15 to 20 cms. The factorygasket was in perfect condition. "Waste" the extra 35 quid (price @ my machine shop) 45 sounds a bit excessive

Note for anyone suspecting a cracked head - If you take the rocker cover of with the engine running and the cooling system up to pressure, you can actually see beads of water emerging from the cam bearings if that is where the problem is.
