Hi,
I pulled plugs the other day and a thread insert came out with #3 plug. I haven't tried to separate them yet but afraid the insert is rusted to the plug and will be damaged when I try to get if off. I have a couple of questions and am hoping maybe the answers from the community will be a PSA to other new guys who face this issue.
1) Assuming I either get the insert off or buy a new one how do I keep this from happening again? Is there a specific type of thread locker that I should be using?
2) IF I can replace the insert how do I measure to ensure I get the right one? Is it just the OD of the threads? I've seen a 14mm insert set on CIP1 - do I need to worry about thread rate or is this a fairly standard part?
3) Any best-practice general advice on dealing with inserts and heads?
Thanks very much for your advice,
Rich G.
