Re: Carbon deposits(?) in cooling system
Thanks, got some nice black engine paint already so that will save a few quid! I briefly tried turning it over this morning but to no avail. I could hear a kind of 'put... put.... put...' so I think the air is already breaking out from the part of the seal that has already given way. I will carry on at it after work and see if I get anywhere.

Re: Carbon deposits(?) in cooling system
At work I get a very similar problem with Common Rail injectors, being seized in the head. I use a Forch product called R579 Injector Cleaning Agent. It is described as a Ion activated penetrating oil for releasing and cleaning of rusty, coked and sooted components. in Truth is smells and feels very like diesel. It is very good, soak injector for half an hour and it usually comes out fairly easy. I am not a fan of putting string down the plug hole. What I would do is spray lots of the R579 around the offending stud. Remove all other studs except two diagonally opposed ones at the outer ends of the engine. Put nuts back on the two studs leaving a gap of about 1/4 inch attach the cylinder head to the engine crane and lift car so as the cars weight is taken by the crane, just enough so you can slide a piece of paper between the tyre and the floor, leave suspended overnight usually does the trick if not I have two wedges made from an old leaf spring that can be knocked in to the gasket between head and block giving you enough room to saw off the offending stud with hacksaw blade.

Re: Carbon deposits(?) in cooling system
Yeah I did wonder if the string in a cylinder might risk breaking a piston if the head doesn't give way.
Re: Carbon deposits(?) in cooling system
A cheap way is a can of coke pour around the stud & leave over night works for me getting out diesel injectors

Coke cures many things. Also great for cleaning out ‘hot’ radiators

Re: Carbon deposits(?) in cooling system
Just thought I would update you all on the progress. I bought some WD40 specialist penetrating oil, one of their new product lines. Using this is helping by the feel of things, the entire head is now loose from the block although at the moment it is still being held down by the seized stud which I think has rusted itself to the head. I've let it sit overnight to do its work so I am going to carry on attempting to free it in a sec, hopefully it will have released or weakend the bond. I still have an alternator to fit, switching out the dynamo setup so theres plenty to do in the mean time!

Re: Carbon deposits(?) in cooling system
Just thought I would give an update on the progress of GRO, the engine is back together now, and it is looking much smarter than before. I am just getting over the trouble of getting it started now, we have a spark, compression but for some reason no fuel, the carb is really giving some trouble. I removed it today and blew through the fuel line and a lot of crap came out but it made no difference. The most I have had from it is a little wobble as it spluttered a tiny bit but other than that it is as dead as anything! Nothing is ever simple with this one but I'm sure we will soon get there, if anything I'll see if there is an exhange service and fit a recon carb. Here's a photo just to show the results, may not be running yet but at least it looks much more pretty!

Re: Carbon deposits(?) in cooling system
The head sounded like a right nightmare to deal with! Perseverance pays off
Have you checked the pipe under the carb? It has a spring around it to stop it from getting kinked but sometimes the pipe becomes weak and pinches up anyway. It was the reason I couldn't figure out for weeks why my car wouldn't start.

Re: Carbon deposits(?) in cooling system
It all looks very smart have you had the top dashpot off the carb and blown back trough the jet into the float chamber making sure the pipe Morris refers to is clear. When you put the dashpot back on make sure you can lift the piston smoothly and freely to the top with ought the dashpot damper in it should drop back onto the bridge at the bottom in under two seconds with a sharp clunk.

Re: Carbon deposits(?) in cooling system
Thanks for the tips, perseverence was the key to success on this one, it was a real nightmare and it has had a lot of work done which, now, stepping back and looking at it I'm very pleased with. I've not looked at that pipe in full but I will, there may be a chance that has happened as it was placed in a shed on a bucket of mole traps whilst we did the head. I did notice when I partially stripped it that the fuel would flow through at some angles but not others strangely. Then a load of black sediment ran out of it and it seemed to clear it up although it was blocking the air flow every now and then, a kinked pipe may be likely.
I've not blown back through the opposite way but I will give that a go too, the carb looks pretty original, it's only had a new needle whilst I've had it but I'm not too sure if it has been rebuit in the past certianly needs doing if so. I will see if I can get it going and probably swap it for a recon when I'm not as skint! P.S Dave, the ignition lights are working fine, thanks for all your help with the alternator conversion!
Cheers
