Threaded sump plug - nightmare!

alan s4 · 05-03-2021, 01:54 PM

I've changed the oil dozens of times over the years and I'm always careful with the filter and sump plug.......

Changing the oil this afternoon and noticed that the sump plug (changed to a bolt type instead of the original hex type last year) wasn't tightening up. Not over torqued as I hadn't got to that stage yet!

Plug now turning in both directions without tightening or coming out. Clearly threaded.

What are my options?

1. Helicoil feasible?

2. Can the sump be changed without splitting the cases?
