I'm thinking of getting the blowlamp on the plugs on my 606 before undoing them. Any thoughts?
I would have thought that would make them expand and therefore tighter.
I wonder if getting the engine hot them using freezer spray on the glow plugs would free them up?
I have a freezer spray which will with sufficient application go down to -50'. This is from a very small nozzle same as a WD40 straw so I beg to differ. I have used it for thermal shock to break the seal on rusted bolts.I think it would be hard to focus the effects of freezing to just one part. Since they are in contact with each other the head would also experience a drop in temp. Thus giving no benefit - a waste of time! I agree that a little tug clockwise would break the plug free allowing you to unscrew it more easily.
