Hi folks not been on here for some time now but im hoping use can help, ive noticed if my03 wrx has been sitting for a few days on start up i get a puff off smoke out of the exhaust, im pretty certain its not condensation, and after the initial puff on start up it clear, any ideas whats causing this, and more inportantly is there somthing i should be fixing just now to stop costlier problems, its got all the usual mods and is running 340bhp

 

its condensation , dont panic

 

What colour is it?

 

Im pretty sure its smoke, ive had the car 5 years and this is pretty recent, when its condensation it continues for a few minutes at least, this is just one big puff of smoke on start up, thats why im baffled by it

 

White/grey

 

Maybe you just need to change the spark plugs - un burnt fuel. Battery slightly under voltage perhaps.

Just take it out, drive it like Bonnie and Clyde stole it.

 

It fecked, get it scrapped. Better still I'll have it from you for £500

On a serious note, is there any smoke under load, or when it's been run for longer than 15 minutes? Is it using any oil? Obvious checks have been done, no contamination issues?

 

What??? Bottom Ends gone surely

 

Battery flat = smoke.... ?
