well now that I know it is the head gaskit im somewhat glad to finally see some light at the end of the tunnel, its been 2 solid days and a full night working on this, and to be honest I did think it was a little under powered by comparison to my older 200tdi disco(im going to miss that thing).. But at the end of the day I see it all as a quality vehicle bonding experience, next will be the rear main seal.. I might do the clutch, spiggot, throw-out bearing and seals at the same time.. but thats another project, I still have to transfer the wheels, suspension and flexi flares from the old one as well, looks like I have a busy week ahead..
now, if only this rain will give us all a break!

Nothing like getting gunked up with **** to find out what makes a motor tick!
I am busy as this weekend as well nothing like it really ...although it can be a pain in the arse the feeling of self satisfaction after completing a job ahhh great!!!

Agreed! ..problem is that my other half now knows I enjoy it(must have over heared all the drinking and laughing and carrying on).. so no longer have an excuse to get out of other s*** around the house.. I tried telling her washing clothes and such can be enjoyable.. ..but then I got that look..

OK, I got my head back today, it passed integrity test and is all shaved and ready to go, I have cleaned up the block using a razor blade then cleaned it off using metho and a green scratchy finished with a buff off with a clean rag, that took me most of the day but now its nice and clean.. now just awaiting gaskits, bolts etc in the mail, they should be here tomorrow.

OK, its done!! the head is back on and everything is running nicely I did the tappets before turning it over just incase the clearances had changed due to head shave, new gasket etc. took it for a drive and temp is nice and there is deffinately a noticable performance increase.

To be honest im kinda glad I went through everything else first, I now know it is all done.

I will drive it for a day then drop water and oil and give it a full service.

Total Cost:
Head Shave and pressure test - $150
Head Gasket, tty bolts and rocker cover gasket - $185(after delivery)
after petrol and beers total came to around $380.

Very happy!!
Thanks for all your help.

Never really understood why these exhaust valves were placed ajacent each other. Its right up there with the Nissan ZD30 having the ports paired front and rear instead of left and right and both sharing a common port runner ;/
It ends up being the hottest part of the head. With all the new 300 heads ive sold in my time, this was a reasonably common area for failure with them.

With the glow plug holes, a quick nip with a diegrinder to the square up the sharp edge and stress relieve it makes a difference to it cracking, bit this is generally not an issue.

Good to hear its all sweet again!

Andrew I have wondered this too, and the only (this is weak I know) thing I come up with is it gives two exhaust runners to mount the hairdryer up to.

I wonder if with more MLS (multilayer steel) gaskets getting used whether we will see less delamination failures in that area?
