Hi everyone. I was doing a routine oil change on my 1982 xj6. I’ve done about half a dozen of these previously without any problems, however, this time the helicoil came out of the sump when i removed the plug.
I have another xj6 engine and removed the sump plug of that to compare it and noticed it’s much bigger than my original sump plug. I think the spare engine is of a 84 or 85 xj6.
What do you think the best corse of action should be ? Do you know what size the tap thread should be if i use the bigger sump plug or should I replace the sump from the 1984/85 motor ?
Thanks for your time and assistance.
