Hi Guys
I'm new on here I have just bought a scooby it's a 02 plate wrx, I have a intermediate smoking problem, it happens when I am going down hill in gear but no throttle ( overrun ) can anyone tell me what causes this...? Thanks

 

What colour is the smoke?

 

It's a light blue if that helps

 

rings . on over run . stem seals on start up

 

Ok thanks any idea on cost to get repaired..?

 

If your pulling it apart you might ask yourself is it worth changing crank rods and pistons. Couple of grand to do all that. Is it worth changing rings then have the crank go later on?

 

Worth thinking about forged goodies aswell

 

how bad is the smoke ?? if using less than a litre of oil per 1000miles dont bother. saying that you might have fun and games with emmissions next mot . the chhep option and poss half cure is to fit a oil catch can

 

if its blue it can be a number of things it can be turbo seals or the stem seals or piston rings and fitting a oil catch can will do nothing for the smoke or emisions really as the oil is getting in after the intake stage the cheapest option is the turbo and if its not the turbo it will be cheaper to buy a second hand engine from a breaker on here.

 

Thanks guys
