tom.mattin Posted April 25, 2018 Share Posted April 25, 2018 I have a impreza wrx blobeye 2003, decat straight to a (tiny) box with twin exits. On idle at say traffic lights they smoke up like !Removed! and you can smell what seems like oil and fuel but smoke colour is white. I assumed this was because of the decat. I know on idle it does 0.6% co2 and rev 1.5%+. Only does it now and again whilst in motion, usually after boosted. It also uses a bit of oil every so often but coolant levels are spot on and no junk on oil cap so don't think it's head gasket but haven't done a compression test or anything. Am I being paranoid or is it just because I have next to nout stopping my lovely jap fumes Sent from my iphone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Marshffs Posted April 28, 2018 Share Posted April 28, 2018 Have you had it remapped after you took cats off? Will be running very rich i would imagine. Quote Link to comment Share on other sites More sharing options...

I did have, but it does drink tons of fuel. Don't want to have to get it remapped AGAIN. It's not cheap :( Quote Link to comment Share on other sites More sharing options...
Marshffs Posted April 28, 2018 Share Posted April 28, 2018 No its not but if its drinking gallons your best off getting it looked at to see if it is rich/lean. Think of the fuel money if its drinking it. Could be nothing wrong with it and maybe the outside temp doing it. Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted May 16, 2018 Share Posted May 16, 2018 Sorry I'm late to the party. My classic started running extremely rich. It bore washed and the oil was very thin. Fortunately I did go for a Dyno when noticing something untoward. The afr was so rich it was off the scale. Turned out to be the MAF. I switched that and had it mapped again. All good since. For the cost of a Dyno, I'd say go get it checked atleast. Keep an eye on your oil and if it's smoking, I wonder if your oil is already thinned and seeping past seals. The end result is a lot more costly than a diagnostic Dyno and possible remap. 2 Quote Link to comment Share on other sites More sharing options...
