2004 Subaru Forester XT (original turbo w/ 69k miles), 3" catless dp, oem catted up, k&n panel filter , sti catback, cobb ap OTS stg 2, shell rotella T6 (was amsoil XL previously).
Other things to note: Never overheats, needle (when up to temp) is always under half. Gas mileage is great (I came from a lifted truck before this).

I don't notice white smoke upon cold start, usually takes a minute or two for the smoke to make an appearance. I will then only see it at idle (and not all the time either), I don't see any smoke billowing out behind me while the vehicle is moving.
There is no smoke coming up from the oil fill or the dipstick and the oil, which was changed a week ago was not milky at all. The coolant is nice and green, no chunks or anything weird going on there. I haven't noticed any coolant loss but I guess a leak could be so minimal that it just hasn't shown up in the overflow level yet? I just added subaru additive to the tank as the previous owner did not add it at the last fluid change.
I see no signs on the exterior (engine wise) of any leaks and neither did 2 subaru techs (for what that is worth) at 2 different times.

I did notice this small leak:

Turbo looks a little wet on top, not sure if this is normal:

I pulled the TMIC a couple days later, spots where oil was found are circled. It didn't seem like a scary amount, just a little bit. I also found some in the throttle body/tmic coupling, very light film of oil. I noticed nothing in the TB inlet though.

I was about to put it all back together when I took one more close look from the driver side. Looks a bit off to me but what do I know?

Things I have not yet done:
Pulled the plugs, compression test, leakdown test

I pulled a muscle in my lower back on Saturday while helping a friend with his car, put me out of commission this whole week. I need to get the tools to run those tests or find someone that would be willing to help. Would a combustion leak tester be a good idea? I didn't notice bubbles under the tank cap but I am going to try again later when the car has completely cooled down.

I appreciate any and all help/insight before I have to suck it up and take the car to a shop.

Popped off the rad tank cap and started the car (heat on full blast), didn't take very long for it to overflow. No bubbles at that spot but there were lots of them in the overflow tank.
 
Welcome & sorry you're having problems. Can I assume you are LH drive / US based? Pls add your location to your user profile as it helps members help you.

A warm :welcome: to the ORS forum mate :).

I don't know nuttin' about the turbo engines, but it would help others to help you if they have some idea where you live -general area is fine. Put it in your member profile.

There are quite a few people here who should be able to help. The missing item from that square drive hole doesn't look all the healthy to me though ... :(. A few bolts missing too, by the look of it.
 
Thanks for the welcome! Updated my profile, yeah from the states. Florida to be exact.
Which picture are you referring to with missing items? As for the bolts, they are mostly missing from brackets I removed and the tmic.
 
Last piccy DF. Looks like it is either a sensor connector, or a square drive with a missing cap, or cable ... I am certainly not even familiar with the object, just looks as if it is missing something to me.

I assiduously try to avoid even looking under our cars these days! I check oil, water, tyres and all the various reservoirs reasonably regularly and that's it! Loved fiddling with cars when I was 12 to about 55 y.o. These days, I avoid it whenever possible.
 
Only thing missing in the last pic is the heatshield on the turbo.
This is the first time in a long while I have ever had to actually dive into the engine bay of one of my cars, it is both stressful and interesting. Much more stressful than interesting though, lol.
I just want to get my new shocks and minimal lift in, pop some 215/65r16 AT's on it and get back to dirt!!
 
Sorry to alarm you unnecessarily DF :o.

When I looked at it more closely, I can see that it is a trick of the light. What I was looking at was the end of the bolt on a flange clamp, and interpreting the shadow in its centre as something else! DOH!
 
Monsterskulls is down there in FL, he loves to drown his foz and put it back together! He may be of some help to you. I think the last thing i read of his was "my wiper blades won't turn off when my car fills up with water". :lol:
 
G'day domoFOZ & :welcome: to ORS.

Sorry I can't help with the problems you are having with your Forry.
Things in that are are a little beyond my expertise.

I'm sure there will be someone who has a little more knowledge in that area will pop in & be able to help you out though :)

Regards
Mr Turbo

No worries, I don't think I can get anymore alarmed with this car. :lol:
I am already anticipating fried ringlands. I am either wonderfully wrong (bad turbo) or right.

Compression test will tell you one side of the story. A leak down will tell you the other. I'm too having blue smoke issues only when cold in the morning. I'm hoping it's just a PCV valve, but accepted that it could possibly be bigger (rings).
 
haha, sort of like getting your annual physical if you're to the age of doing that.. Never know what they're goin to find! :lol:

Especially when they examine your exhaust! :ebiggrin:

Yeah I need to order a tester, I was looking at this one, any opinions?
[ame="https://www.amazon.com/gp/product/B0030EVL60/ref=ox_sc_sfl_title_1?ie=UTF8&smid=ATVPDKIKX0DER"]OTC 5609 Cylinder Leakage Tester Kit : Amazon.com : Automotive[/ame]

I know I can make one (https://forums.evolutionm.net/evo-h...w-make-your-own-faa-spec-leakdown-tester.html) but if the OTC one from Amazon works, it would be easier than piecing one together.
 
Im not sure which cylinder is which so here goes. Rear is closer to firewall.
This was done cold.

1? PF - 137
3? PR - 138
2? DF - 135
4? DR - 140

Leakdown results (done cold):

PF: 5%
PR: 3%
DF: 3%
DR: 2% (heard slight hiss from oil fill)

Each cylinder was done 3 times. The 2nd time because I forgot to take off rad cap and check for bubbles, 3rd time because I forgot to remove the oil fill cap.

Now you guys, that's hitting below the belt, AND from behind ... :iconwink: :rotfl:.
They hit me from the front in the mouth as well ... ;)

At least mine's over and done with for another year ... hopefully.

That all looks reasonably healthy to me. Are the results within spec?
