need some help figuring this out
So all of the sudden driving home from work tonight my truck started acting weird. It started to run a little rough like its not firing on all clyinders. But I don't have any lose in power. It sounds like its not running on all clyinders but I don't hear it missing and at idle when I looked under it there was a slight white or grey smoke I couldn't tell for sure since its dark out. It's doing this on the passenger side. It smelled kinda weird to. But I don't think its a head gasket because it was not running hot and there wasn't crap on the dip stick. Could my choke be causing this? I haven't checked it yet. Or a loose rocker?

It's fixed! Went out and checked the choke it was open went and did a compression check on the first two clyinders and they looked good cranking both were exactly at 118 psi checked the number 3 cylinder and the spark plug was wet so I hooked up the gauge and my compression was 30 psi. Crap! So I pulled the valve cover and low and behold the exhaust valve rocker was loose. Cranked the engine over till that lifter was all the way up then I tighted it down to 23 ft. lbs. went through and checked that whole side I had another one a little loose. Buttoned her up went out romped a bit and she doesn't run good she runs great!
, if you hang in there, there isn't anything you can't fix on these trucks.....without a half million dollars in test equipment to tell you the fuel cap is loose.

Loose rocker was my thought too. Beat me to it. I had the same thing happen a few years ago. Blowing smoke all of the sudden. Popped the valve cover and found the rocker shaft bolt on # 7 cylinder was barely hand tight! Tightened it up and voila! fixed.
Glad you got it squared away.
