Took packs out tonight, the 246 one was replaced with a genuine Bosch one when I done the TB work, however the 135 one, which looked fine, was kept. I noticed tonight there was a slight crack on the plastic where it bonds to the internal metal, perhaps indicating corrosion on the inside on one of the plugs on the 135 coil. The metal looks ok, although not as bright as the new one.
The new 246 coil however does look a bit less shiny on the little springs inside the spark plug sleeves. Not sure if that is damp or what.
This is the slight crack I can see on the middle of the 4 plastic holes where it bonds on the 13 coil.
This is the 246 coil:
Thinking on treating it to a new set of plugs. Would you condemn that coil for that small crack? Any thoughts? I'm going to have them sit on the window sill in the sun for a couple of days to let any moisture out.
Also, the scuttle is not leaking at the passenger side anymore, but is pouring out below the wiper on drivers side, luckily the water is dripping straight down past the steering box to the deck. While this is not hitting the plug area, at least when not driving, I would like to get that fixed. I did put a bit of tape over the wiper hole, as it was leaking through that. The foam seal had seen better days. However initially that looked to have fixed it, but is dripping out again.
Any thoughts on fixing the wiper hole properly without removing it all again. Not that I don't mind removing it, however I had sealed the other end and will break the seal if I remove it again. Thinking I could take wiper arm off, get a square bit of duck tape, small hole in it for wiper spindle, put a dab of grease at hole to stop it sticking to wiper spindle, then place it over the hole.
Cheers
