When you say lines, do you mean the HT leads?

F'kin spell check, LINERS as in barrels.

Good idea, the problem is two rebuilds. Not cheap. I have another set of barrels I can use but they will require a rebore. This time I need to find the"smoking gun" before I do anything. I thought I had last time as the Cruzinimage head gasket had defo gone, but wasn't to be. If I do find a cracked liner I can always rob a sleeve out of the other set and just have one pot rebored. That's probably the cheapest option. But I do need to find the problem this time.

Then when we start welding as soon as heat is introduced the crack opens right up. Maybe yours does not show until heat is involved. It seems like you hav already thrown a shit load of money at it. Good luck with it.
You will need the full kit.

That looks interesting. What's the procedure for using it.

Very simple but very effective. Give everything a good clean with the spray cleaner and dry, then spray on the penetrant which is usually a red dye that works its way into the fault leave a while then clean again, then spray on the developer which is a white powder. If there are any cracks or faults the powder draws out the red penetrant from the crack showing the problem area. Quick and simple to use. I don't envy you, frustingto say the least.
Nurse Julie:
Helping you clutch at straws here Roy. Is the valve stem seal intact, a good fit, not cracked or ripped. Easy one to check and costs nothing 😀😀😀
Is the valve stem the correct size, ie, the same as the other valves?
