Hey guys
So I just noticed today my r33 turbo started to spit this black sooty stuff. It was out in the rain last night and I've never really seen it do this before, I changed the oil in it last week to penrite 10w50 synthetic, not sure if that could cause it? Any other ideas?
There is a little carbon build up inside the tip of the exhaust is it just the water mixing with the carbon?
Seems to run fine except for the black stuff
Any advice is appreciated:)
