My spark plug seals have become loose and floppy and don't press against the openings. They just slide away on the wires.
Does anyone have any suggestions on what would improve the seal? Are there some seals that work better than others?
It would be so much easier if the opening in the tin was in a flat plane like it was on a single port head.
I have some Toyota FJ tie rod boots that are approximately the right diameter and they have a lip to grab the edge of the opening but I don't think they would conform to the "bent" opening.
