There are quite a few possible reasons for coolant not to return from the overflow bottle that do not involve removing the head - have you confirmed that removal is necessary?

Sorda, It's been happening for a couple of months, just didn't worry about it during winter. I put the breather hole in the thermostat at the front. Mine wasn't, damm, still did it. New hose and lid on bottle, and new radiator cap.
It now idles rough, and misses on No. 1 cylinder. What other cause is there ? bye

Any leak anywhere in the cooling system will cause it not to build the vacuum necessary to pull the coolant back, and likewise there are other causes of a rough idle and a misfire - you have to be the one to be certain the head gasket has failed and is the cause of the symptoms.

I park it on lino, so can see that there are no leaks. When it started running ruff, I pulled the plugs, and No.1 looked iffy, changed the plug lead and cap, no good. It's off now any way Bits of dirt fell on the head whilst I was fooling around, can I degrease it, and then just hit it with air ?. The manifold bolts weren't very tight at all, which is good, 'cause the tension wrench I'll be using is very old and looking a bit rusty, so I might just guess. Any help and suggestions welcome.

No.1 actually had water on top of the piston, too hard for an old man like me to post pictures on here.

I had to put it back without a tension wrench, but you know I undid them, so did them up my guess of the same tension. Same day, so I sort of remembered. Anyway 2k"S, and no bubbles, which occurred just zoom. Had been not sucking back from overflow for a while , but not enough to worry about. Easy day job for noob if you don't do machining. I had the gaskets.

The reason I did the head gasket was that the idle had got too unpredictable. The miss went away. but still huntered, and idled at whatever it felt like. Standing ovation for "losfer", I remember reading that he said if idle is fucked, it will be the round thing with wires out the end. Just hit it with carby cleaner and air; like a bought one.

The packaging says to retension head bolts after 500K's. I can get a wrench at any time now, but..do I loosen them then tension, or just leave them if some are over tensioned ?.

So I don't loosen them?. Just go around and tighten them to say 60nm ?. If they are over tightened, just leave them ?.

I doubt they would be over tight
I wouldnt loosen them, but follow the torque up sequence in the manual
