Blue Smoke on Startup - GRF A-line


Recommended Posts

So a while back my 2010 sti a-line started puffing a little bit of blue Smoke from the exhaust on cold start

 

It went away for a while and recently started doing it again, it is quite a cloud on start up but will only do it on a cold start and goes away after a few seconds

 

Any ideas? Car has just clicked over 120,000kms and religiously change the oil every 5000kms

If it's the valve seals it will also smoke when you come off throttle as as engine vacuum sucks oil past the seals.

If there isn't any smoke, then either it's not the seals, or not enough of a problem to worry about it.

 

When my turbo seals were going, there was visible oil in the rear housing, but thinking about it, it smoked continuously

not just on start up.

 

Also, it might just be nothing... the engine is horizontal so maybe oil is running off the sides of the cylinders and pooling

at the bottom... and just gets burned off when you start it up.

 

Probably best not to worry about it if it's not using a lot of oil and you don't have to top up all the time.

Yeah I figured it may be nothing but it's alarming when u see a huge cloud of smoke out the back like that, but yeah it definitely only is for like 2 seconds on Startup, car runs fine too and doesn't seem to use hardly any oil

 

Just had a thought I had it serviced by sas on the 29th December so may be it was slightly over full or something?
