Hello. Yea, I know it's another exhaust smoke thread. I've been trying to look into it as much as I can but I've been short of time lately.
It started several weeks back after a driving home from work (a good 25 to 30 minute drive) in cold weather. I got home and noticed a bit of smoke coming from the exhaust. I immediately jumped to conclusions and assumed it was a blown head gasket. I don't recall it ever overheating the 1+ year I've had it but who knows.
So, I kept a watch on it and borrowed another vehicle to go back and forth to work. I can swear that throughout the time while I checked on it there was either: no smoke at all, smoke pretty much only out the driver side bank, or equally between both exhaust sides.
I couldn't see anything physically wrong in the engine bay (some oil along the valve cover gaskets (not a big amount but something I might have overseen earlier; I'm gonna replace them asap). I then did a block test (little tube thing with the reactive blue liquid) to check for exhaust gases in the coolant. I did it from a cold start and up to where its warm. I got nothing. This was a day where it decided to not smoke at all, mind you.
Just recently I had some time to work on it again and I decided to do a compression test. The results:
4 - 160 ; 8 - 155
3 - n/a ; 7 - 155
2 - 160 ; 6 - 158
1 - 160 ; 5 - 155
I couldn't get the adapter and hose to fit in Cylinder #3 bacause the header runs right by it and there wasn't enough space.
The results basically came back all 150 to 160 on everything (The gauge didn't really have precise numbering 130 - 140 - 150, etc.).
The car still runs basically as fine as it always has. It doesn't struggle or idle very rough or even surge, as far as I can tell.
I even took a quick video one day when there was some smoke and after I took a short drive to warm it up. Sorry about the small and bad quality. I only had my phone on me at the time.

I was wondering lately if it could have something to do with the lower intake (or is it the intake manifold). I had to take it to a shop to get the bottom bolt of the thermostat housing removed and re-drilled when I broke it off. They had to remove it to send it to a shop and I was wondering it they did a crappy job putting it back on.
