Help Diagnose My Car's Problem - Video Inside

I think its the turbo seal but I need feedback and opinions. I'm the type of person who gets really concerned when something is wrong with my car.

The car has been sitting for over a year, so the gas is bad. The smoke has just gotton worse as time went by. At first I thought maybe it was the valve stems because it would smoke and then go away like bad valve stems, but now maybe I think its the turbo seal? The old gas probably contributes to the problem too I think. I know when I first stored it for the winter when I first got it, and the gas got old, it would smoke in the Spring but as I got new gas into it and started driving more, the smoking dissapeared all together. I did a compression test a year ago and the numbers were fine. I start it up every so often while I stored it.


09/03/2010, 61 degrees F, cold start, driver side door was open from the beginning. Notice that the oil pressure is high during a cold startup due to no balance shafts, it drops down after a few minutes after the car has warmed up. There is an unpluged bung for a wideband on the downpipe. Bad gas, gas is over a year old. Shot with HTC Evo phone.

09/03/2010, 61 degrees F, after 10 minutes of idling, driver side door was closed from the beginning. Notice oil pressure has gone back down. There is an unpluged bung for a wideband on the downpipe. Bad gas, gas is over a year old. Had a hard time reving the engine and holding my phone at the same time. Shot with HTC Evo phone.

i would definitely do another compression test. also check your plugs. you should change your oil. seafoam the car to clean out the crap that has been sitting for so long. that would be where i started and go from there.

Plugs are clean. Oil is already new. I don't see the point of doing another compression test? I havn't been driving it around. Motor is a 2.4L G4CS hybrid with 13,700 miles so I don't think sea foaming is neccessary. It was mainly used as a Summer driver/weekend fun car.

I drove it through one winter and that's when I started having problems. I suspect the turbo seal is going bad because when it's cold out like it does in MN winters, the oil pressure stays high due to no balance shafts and doesn't go down until the car warms up. I know high oil presssure isn't very healthy for your turbo seal, but I want another other people's opinions.
