Left bank plugs were not loose, and
while I was in found that my coilpacks are cracked, so there's that.. Ordered me 6 new ones.. I hope they are the right ones or come with the new bolts.
The one near the cat was the worst, but they all had cracked housings, and I was on borrowed time with these.
Got a borescope in the plughole, pistons looked good, not much carbon.
it's one of them 5 bucks Aliexpress scopes from china.. so not all that great, could not pan the head around to see the cyllinder walls.
Buttoned her back up with left side plugs done, i'll do the rest when the coilpacks arrive, so i don't have to redo 2 sides later on.
