Nah man dont give up now, its only a head gasket mate, you wouldnt be the first to have blown or changed one. so keep on the right track to being able to enjoy it after youve done the head gasket

Well I took the head off today and found what was really wrong. NO.2 Inlet valve wasn't closing!. I don't know yet whether someones *uck up when changing the Timing belt / the valve is slightly bent or its the good old fashioned Carbon build up. I took off the rocker bars to make sure there all shut to check and I could see light on No.2, so there you go. I've checked the HG but it covered in too much *hit to see were it has gone. Anyways I had a good spare head which I've stripped for a thorough clean, skim and recut valves etc to save some time. One other thing though I have noticed that Oil was leaking from the tubby around the core/Exhaust housing so the seals are Fubar. I'll put up some pics later
Thanks Wacomuk!

Well on friday I went down to my mates Engine reconditioning unit in Tottenham were my cylinder head was overhauled. It was stripped cleaned throughly and skimmed. The valves were cut and the seats had the Three angle job done on his serdi machine. Heres a few pics of it done. Next job to refit it and find a decent SH turbo which I've had a few offers so far as mines Fubar !

Looks like they have done a good job.
Are you going to helecoil the manifold studs and rocker shaft retaining bolts? Nissan really did fit those valve heads tight together.

The two studs missing have been Helicoiled by myself already. The rocker ones are fine as I checked them whilst it was stripped. Had to use a drill with a wire attachment in the ports to remove the carbon and muck!

It should turn into a really nice reliable s12 (is there such a thing?
)Are you keeping it auto and is this to eventually replace your grey s12?
