2018 FA20 Stage 2 Tuned for Speed Density Blue Exhaust Smoke Question

MosesDisciple · 06-29-2022, 10:07 AM

Base model WRX (2018)

I'll get right to the point:

Mods:

Stage 2 Tune for Speed Density
COBB AOS, CAI & Turbo back Exhaust

Oil Used: 5w-30 full synthetic

On cold start after sitting and while idling at stoplights or a long wait a stop sign I will get blue smoke out of the exhaust. I have no oil leaks and I am noticing some oil consumption.

Could people please provide some areas that I should check to see if I can rectify this issue?

Thank you!

If you are losing oil then it is very likely a bad turbo seal.

Also worried it could be that. I'll try this first and say a small subaru prayer considering I have 66k on the car.

That Perrin part fixed the same issue completely on my 2016.

Installed today. So far, so good. Too early to tell for certain though.

Update: I still get the blue smoke sometimes. I recently used Royal Purple 5w-30 and the first 1000 miles I believe I noticed significantly less blue smoke after idle especially. Now above 2000/2500 miles I'm noticing it a little bit more and there is a slight bit of black film on the rear bumper. Nothing major, but I can notice it if I don't wash the car for a bit.
