K series head gasket repair
This one is realy for Scotty P as I believe he has repaired a K series HG before. Unless someone else has too.
Have I got all that I need.
I have the following
Head gasket (Mk III OEM Paten 7560 - not LR)
New Head bolts
Camshaft etc oil seals (came in a kit with HG)
New Steel Dowels
Inlet manifold gasket
Exhaust Manifold Gasket
New Cam rocker cover
New Cambelt
New Cambelt Tensioner
New Waterpump
Flywheel Lock tool
Camshaft Lock tool
Oil; and Filter
Coolant
Torque wrenches
Thinks thats it. I have replaced waterpump and removed and replaced cambelt before (not new one, so never had to remove engine mount,just put old one back on-long story, to do with last years postal strike  ) I understand its not much more complicated than that to rmeove and repalced HG?
Anything else I need. (I am assuming that as I am only very slowly losing coolant and very slowly getting oil in coolant, an NO water in oil, that I will not need to skim head etc)
Hopefully get a low coolant alarm in time for the weekend too.

Re: K series head gasket repair
Ok broon
good news you have more then you need lol, tho im suprised ur not going for the LR head gasket with the stiffer oil rail!
You can lock the fly wheel if u want but the engine never moves unless turned in my exprience.Things to watch ot for there is a small nib sort of thing on the lower timing belt sprocket watch it doesnt snap off!
Ur head bolts will have points on the end of them yes? If so grind then off back to the thread, a few ppl that have taken off the sump when doing HGF repair have found the points can dig into the sump and effect the torque level on the bolt!
In my experence ther is no need to replace the water pump ive had HGF on my 200 and the ZR both times the water pump was fine and was not replace! however if u ahve bought 1 you may aswell stick it in!
With the MGF there are extra's issues with HGF the underfloor pipes give them a check make sure they arent leaking, also you may want to think about relocating the thermostate with 1 of the new fancy pressure operated 1s! see PTP's website.
Finaly the bad news you may need to get the head skimmed, coolent leaking out over a period of time can cause a mark on the casting and sealing face of the head. check the head when u take it off, also have a look at the water ways in the head, poor casting can sometimes leave these thiner then they should be!
think thats everything

Cheers  
Need to look at bolts when I get home. As far as pumps, it was the water pump that led to my first HGF, and I replaced it just last year (after only 21K) as the new one was leaking too. I am gonna do it for the sake of 20 quid, while she is stripped for me.
I bought the Mk3 gasket by mistake. Apparently, this was the one MG sorted before going tits up, it has extra reinforced beading and many people still recommend it as being good enough. I will try it anyway. Pipes are only a few years old, but I may do them anyway, as they were cheapos off ebay. Stainless ones are going for peanuts just now.
Cheers again.

Re: K series head gasket repair
That sounds like one hell of a lot of work! You better stock up on coffee!
Not sure you need one but you havent got a gasket for the water pump on your list, or do you just use hylomar?

It comes with a little rubber seal. Should I be using hylomar?
I almost went and ordered the multi-layer gasket and oil rail, but was informed again just to use the one I have. As long as my head is true, then it should work a treat. I did invest in some new stainless steel underfloor pipes though.
