The smoke definitely looked whitish in color though...maybe blown headgasket? I haven't check compression yet, maybe I'll do that tomorrow when I get the chance. 
SR smoking a little
SR smoking a little
I raced a friend earlier this afternoon and after racing I let my car idle and I noticed that it had some whitish smoke coming out of the tail pipe. I turned the engine off and had it cool off for about an hour or so and then turned it back off hoping it would go away. The smoke is still there, then I turned it off again and let it cool down fully. I checked the oil level and oil level is fine and checked coolant level and it is also fine. I then started up the engine for the third time a bit frustrated and took it for a drive around the block, it feels fine...don't feel any loss of power or and unordinary noises. After the short drive I had the engine turned off and then opened up the oil cap on the valve cover and noticed the same white smoke coming out of there too, just a little though(doesn't sound too good I know). The smoke definitely looked whitish in color though...maybe blown headgasket? I haven't check compression yet, maybe I'll do that tomorrow when I get the chance.

That is backwards, Blue=Oil, White=Water, but yeah black is rich but no engine should be idling so rich that its releasing black smoke.
If the seals are broken there should be two simple indications.1) (The exhaust seal is gone) You are burning oil that is getting into your exhuast gasses, and you will notice a loss of oil.2) (The compressor seal is gone) You will notice a pool of oil INFRONT of the compressor and oil will coat the walls of the hot pipes. Eventually the seal will go so bad that it releases large amounts of oil and it will begin to combust it, this can be checked on the spark plugs. Dont be mistaken there will be a slight amount of oil in the intake tract past the turbo usually, but if their is a large amount you should know easily.3) And of course if both seals are gone then you will notice all these symptoms. Both of which to me and resulted in a costly rebuild.
Also, if I am not mistaken, compression on the SR's should be around 150 or so. Are you sure you measured correctly?

I checked the turbo this morning and noticed a little puddle of oil in front of the compressor wheel. And did notice a lot of oil on the hot pipe side too.
About doing compression correctly though, I'm not sure as all I did was warm up my engine and then just put the compression gauge into each cylinder(spark plug hole) and had the gas pedal to WOT and cranked the motor. I know I may not have done it correctly...did I forget to unplug anything or do another step in doing a correct compression check?

Im sorry my friend but to the best of my knowledge your turbo is a goner and needs rebulding or to be replaced. The smoke is probably white with a bluish hue that is sometimes hard to spot.
As far as compression goes, I just looked it up on an S14 and its supposed to be: standard 156psi, minimum 128. And it sounds like you did it right, perhaps your battery was not fully charged. I dont know.

Thanks guys for your help. I did check for coolant/oil level this morning and everything seems normal and still smokes very little.
One thing I forgot to mention while doing the compression test was that the 4th cylinder spark plug seems to have seen some detonation or something because the tip seemed to have been crushed together. I just regapped it to .028 and now my engine runs very smooth and idles excellent. But yes unfortunately it still smokes white a little.
J-Spec Tuner: No I have not put on an aftermarket exhaust recently.
SR20DET240: Yes when coolant burns it does have a sweet smell to it. And I was thinking about a Big T28 instead of a S15 BB T28. : )
SpeedRacer1: Thanks for your help bro...I'll look more into the turbo issue. And about doing my compression, my battery is pretty new as I replaced it about 6-8 months ago. Maybe messed up compression gauge?
