head gasket replacment also rocker oring change using a 3thou feeler gauge My first hassle was getting the headers off, I knocked the collars forward to expose the slots and opened them up a touch with a screwdriver plenty of squirt and they eventually came off. Most of the bolts had been overtightened! as you will see, I left most of the hassle and my whinges on the vid for you're amusement :-D I read of the feeler gauge trick on TriumphRat and as you can see it worked ok and is still oil tight.

Getting the head off was a bit of a chore too, with much more banging, pulling and tugging, again with plenty of squirty stuff it came free. The outside head bolts were well overtightened, I think someone had been trying to cure the leak with force! I have left most of the hassle in the vid to show some of the problems you could come across,

Right heads off, so a look at the bore, I am looking for scratches and score marks also for a lip that can form around the top edge of cylinder, a little play on the pistons but nowt to worry about. Then the job of cleaning gaskets this is my way of doing it, if you are careful you should do no damage this is where the Zen comes into it :-D I had to do it so! "speeded up x4" so you don't get bored :-D It all cleaned up nice so no worries there, as for the composite head gasket, give me a copper one any day!!

Taking the valves out on this one, I grind them in, and check the valve guides. They are fairly worn but good for now, the valves and adjusters ends are also misshapen, again good for now.

Mostly preparation this one, scraping of carbon grinding valves ect I fit pushrod tube and get the head in place.

This is tightening the head, showing the sequence I use, I do not use a torque wrench, if you do use one, you must still only turn each bolt a bit at a time, until required poundage is reached. I also get round to fitting the inlet rocker box.

Nearly there! this one is getting the rockers on, as the valves where dimpled and the adjusters are worn I decided to set the gaps by feel, as the feeler gauge can bridge the dimple and give you a false reading.
