I've benefitted from your videos, I like your style. Got me started on repairing cars. Saved me a dump trunk of ones.
My BMW 1994 525i inline 6 has a spark plug ejecting out of the third cylinder from the firewall. Swapped coil packs, put a new wire because the old was obliterated. Same thing. It's stripped out the threads to an uneven oval on the head. What are your thoughts of identification?
I plan to get helixcoils to fix the head, but about the pressure? I have a good amount of tools, this is not even the backup to my dd. I like hands on learning.
