Has anyone had any luck keeping water out of the coils/coil connectors? I've got a h20a v6 and the coils hate any amount of water, a little splash and I've got a hell of a miss.
It seems the water is getting in the 2pin connectors and shorting out there. I've been using a CRC spray, not the usual one but a blue one for electrics but it doesn't help much.
Thinking of trying dielectric grease.

Yeah Grease or Silicon is OK,on our rally cars back in the 1970's the Coil & Dizzy leads were Araldited in so the downsize is you have to replace Coil,leads & Dizzy cap together but upside is no problem with water crossings or leads falling out.On our cars the Dizzy cap is sealed to the Dizzy with Silicon.

I can almost guarantee the problem isn't the 2 pin connectors. They operate at 12V, which isn't high enough voltage to cause much of a short if damp or wet. The proof is you can wet your fingers and hold 12V terminals and you won't feel a thing.

The issue will be the HT side. Dielectric grease will be your friend.

I'm with Steve on this - and whilst I'm about it, have you ever changed the "plug leads" - that rubber probe that connects between the coil and the plug - they are available individually and like old plug leads they will cause misfires.

Does your car still have the plastic covers that hide the coil packs?
Not a seal against water as such, but they should protect against the odd splash.
If the rocker cover o rings are leaking & it's damp with oil down the tubes, it can play up - might be exacerbated by a bit of water in the area?
PITA to change the o rings though, as intake manifold has to come off to get the rocker covers off.
I think there is / was a rubber seal in the end of the plug, as it connects to the coil pack - these might be broken / missing, but as has been said, this area is not high voltage.
Good luck, Michael

Thanks guys, cleaned everything up and used dielectric grease on the back of the connectors and also between the body of the coil and the round rubber ring/cap at the top of the stalk, and so far so good.
I think the spark must have been escaping along the top of those rubber caps when wet, they were also covered in sand. As you said gwagensteve it was HT side
Went out on Sunday and had a fair bit of water to deal with some quite deep and all worked a treat, no missing!
