Default Need your advice Please!!!

Hello all-

So I just purchased my 1st WRX.

Year:2002
Model: WRX Wagon
Engine:EJ25
Miles on car:73,000 miles
Miles on engine: 10,000 miles
Mods:
ACL race bearings
Wiseco pistons
AccessPORT & Tune
VF39 turbo
STI intercooler
AVO turbo inlet pipe
STI catless up pipe
Turbo XS down pipe
Turbo XS mid pipe w/cat
Turbo XS 3 " Magnaflow Exhaust w/single outlet
APS B.O.V
Perrin injectors
Cobb short ram intake
Walbro 255lph fuel pump
Cobb Lightweight Pulley

My concerns....this is my first turbo car. When I start the engine white
smoke comes out from the exhaust and seems to stay even when the engine is warm. The car has no check engine lights, has good oil pressure and the dip stick level is filled to the middle. It also is not leaking. The seller told me this was due to not have a catalytic converter and from not being driven a lot since he was laid off..he assured me it was normal. Everything on the car is mint condition so im super confused.

Like I said I just bought the car so Im freaking out because when I initially looked at the car/ test drove it I didnt notice the smoke but maybe I was to excited to notice. I plan on giving it a fresh oil change tonight..hoping it helps.

Any ideas what this could be? Or anything I should look for while Im changing the oil?

Also I was told the block is from on 04 STI 2.5.......the block reads EJ25 is this an STI block? Because I thought STI's were EJ255-EJ257

A couple things to check:

--When draining the oil, look for coolant in the oil (headgasket bad)
--When draining the oil, look for metal flakes/metallic-ness in the oil (rod bearing gone/bad things internally)
--A compression test wouldn't hurt anything, and will give you a good idea at how your block is doing
--blackstone oil analysis is great
--White smoke; check the turbo/downpipe connection. See if you see any oil in the downpipe/turbo housing - that can mean a turbo seal is going, in which either rebuild or new turbo.
--EJ25 is an sti motor from my understanding, I have an "EJ20" for an EJ205
--keep an eye on your oil levels, every gas fill up check it out.
--when draining the oil, put it back into the container from the new oil to see how much you burn/lost

I'm relatively new to the Subaru world as well, but I am in the process of tearing down my EJ205 to replace some spun rod bearings / rebuild it stronger. I had white smoke in my downpipe and turbo housing, and that was causing a little white smoke out the back of the car. I also got a severe case of rod knock, meaning a spun bearing.

Words of wisdom:
--LET YOUR CAR WARM UP BEFORE DRIVING IT HARD
Start it up, let it idle for a while (1-2min), f*** with the radio or something, but get oil circulating, then wait for it to warm up before boosting
--always check oil
--take time to learn about your car, In 4 months I learned enough about a WRX to fully rebuild it, the more you know the longer your car will last/easier repairs are - and then you know the limits of the car.
--If its a 5speed, be gentle on the transmission, its not made of glass but doesn't like to be beaten on like the STI tranny.
--check out the BOV thread

If white smoke I'd check your cooling system as mentioned above. Your oil will look more like latte. Also, start your car and pop open the coolant overflow tank (opaque white tank) and see if it starts to bubble.

Unfortunately white smoke is not normal, as I'm sure the seller knew. You have coolant getting into the exhaust somehow. Follow the steps above and hope for the best.

Ok so I did some checking...
1)changed the oil
2) the old oil was dark brown, no signs of any metal shavings

I then took the car for a little drive, until the coolant temp gauge was in the middle.
Check the coolant reservoir..I saw no bubbles.

Pulled over while the engine was warm and saw "NO" smoke at all from the exhaust.

I did notice at a stop light, when I had the windows down a strong smell of warm oil.
When I got home I sat behind the car while it was idling, I again could smell warm oil coming from the exhaust.

I should mention, the owner said the engine was built a little while back by "COBB Tunning in Oregon" and only has 10k miles. Engine is clean I saw no visible signs of oil leaking from the block. The car itself only has 73,000 miles

This is the old oil drained from the WRX...I did not see any metal shavings,,how do I tell if coolant is in the oil?

Is it possible oil is being blown out the turbo causing smoke to come out the exhaust?
I was reading to unbolt the intercooler and check the throttle body...little oil is be expected a lot of oil is bad

If you see a lot of oil it's possibly a turbo seal. Pulling the downpipe will verify. Worth checked the pvc valve which can result in an oily intake track if faulty due to blow by.
