Could This Be My Problem?

[R33_BFT]

I have a really bad misfire (full wrx) that was intermittent but today didnt go away at all (r33 RB25DET), i thought i'd start with spark plugs...so i pulled everything out and saw that my valley and coil packs had a white/yellow build up!

It's now also blowing white smoke, it gets worse and worse as the car warms up then goes away about 15 minutes later.

Get splitfires.

Water in valley at times???

Pull the plugs. They have coolant on them?

You got water leaking into a combustion chamber overnight [or when you leave it parked for a while. Its only a small leak [for now] and when you get going you cant see the vapour, or as it warms up the leak closes up. Probably not all the way but smaller anyway.

Whatever you have its only going to get worse.

Have i blown a head gasket? I cant go in to the engine this week, but the car won't be moving, ill keep you guys informed, thinking about just taking it straight to a garage

Pull a plug. Report back

Inspect for arcing (can I see some soot spots?) then clean it all up. New plugs since you're in there (assuming youre using copper, if iridiums/platinums only replace if they're stuffed). Dielectric grease should help it stop arcing when you reassemble. That worked for me, and costs next to nothing but YMMV.

Im buying splitfires tomorrow hopefully they'll be here by the end of the week, ill get some more pictures when i take it all out again.
I was advised to clean out the valley (leaving the spark plugs in, ofcourse) and to then replace the spark plugs and coil packs. I was told that it might just be oxidation?

Exactly where is it 'blowing white smoke'?

Split fires won't help if its out the exhaust [they are a good product, have them myself], but white exhaust smoke is burning coolant.

If its just out of the valley, then you don't have a problem really. Vented bonnets and washing the engine bay lets water collect on the valley and it steams up as the engine heats up. But you never seem to get rid of it all, usually you have to soak it up with a rag or sponge.

It is blowing white smoke out of the exhaust.
my main concern is putting in my new splitfire's and fouling them with a coolant leak haha
I'm going to take the valley cover off tomorrow after work and clean it all out and replace the spark plugs and coil packs though

Pull a plug and report back

Coolant leak won't foul plugs.
