White smoke under acceleration until warm

[BugJEB34]

My 2002 would run rough and blow white smoke on a cold morning, less than 40 degrees. After it warmed up the smoke would quit and it would run fine. It threw a code for Cam Position Sensor. Later on it threw P016. Dealer replaced VP44. Still threw code on cold mornings. I replaced sensor. No more problems. Check for codes. In the shop manual there are specs for the sensors. Yours may have both a Cam Position Sensor and a Crankshaft Position Sensor. You may have to check them both, if you have both.

I will check those as well just to be sure. My only issue is the truck runs perfectly even when its smoking. I'm not getting any missing, no loss of power at any time, just some white smoke and it doesn't seem to have any fuel type of smell. Will be taking a look at it all next weekend and will report my findings.

Still check for codes with a OBDII reader...

Had exactly the same issues a few years ago while I was in Yukon Terr. about 2,500 miles from home hauling my big camper. It would smoke like a train (pure white) until it warmed up then BINGO, back to normal when it warmed up and ran like a champ. Drove it home like that and got info on the VP44 and the codes. Apparently the VP44 went "____ up" causing this. Replaced the pump (ouch) and all has been well...knock real hard on some wood. I had barely 100,000 on the clock and kind of anticipated a failure. I was on my 3rd lift pump in 50,000 miles and put on the FASS. Guess the bad pumps were what took out the VP44 before I got the FASS in place. This was my experience and I hope yours is something much cheaper to repair.

Don't worry I plan to pull any codes before I bother checking anything else!!

Sort of good now that your not having to think about another tear down!

Put an Air Dog Raptor on mine & never looked back!

Haha, actually kind of what I was thinking. Either that or take off, slam ob brakes and jump out and do a chinese fire drill getting back to the smoke to smell it. I just have to find a place to do it so my neighbors don't see me pull my truck out of the shop, take off up the street, jump out and smell the smoke, then back it back into the shop. They'd all be over asking my wife if I had went nuts.

I knew this one was going to come up and I'm an idiot, lift pump is a stock one, I replaced it right when I bought the truck because I knew they crapped out often, so the pump is 2.5 years old and I will check the pressure. At that time I didn't realize I needed to get a nicer one nor did I know of the nicer ones. I have a gauge sitting in the shop to go in, but they have been sitting there for a while now, so I need to get them put on. I will plug into the test port and see what I'm getting.

This thread has me LMAO ! Not that your problem is funny, but I just got a visual of what a guy has to go through just to catch a whiff of smoke... while the wife looks on My wife thinks I can fix anything, but sometimes she gets this look of disbelief like I am just bull shitting her LOL !

Went over the weekend and had the codes checked, and no codes at all. Got my gauges finally installed so they are no longer collecting dust in my shop and I am getting around 12 to 14 psi of fuel pressure. I know it needs changed to one of the upgraded models and I'd prefer it stay above 14, but with the new kid and all as long as it stays above 10 I'm not putting that as a top priority. Now that I have the fuel pressure figured out, not codes, and still getting white smoke until its warm I will be retorquing the head bolts and then continue from there. Still no coolant loss, but I do have some weaping injector lines that I plan to get cleaned up when I retorque. Is there any chance that air getting in the lines could cause me an issue with the smoking?

Glad I could provide some humor, won't hold it against you at all. Heck with some of the stuff I do to keep things as DIY I'm really surprised my neighbors don't think I'm nuts. Most of the folks in my neighborhood think changing oil is a major undertaking and anytime they see me working on my truck they assume its just an old clunker that is always broken. Preventative maintenance to them or talking about it to most of them is like trying to explain nuclear energy.

could there be an injector or two that are sticking until they get hot causing the smoke till warm?

Can you expand more on your weeping injector lines? if they are loose i would say loosen the bars that hold the lines together and then loosen then re torque them to a bit more then snug.

Seems that those weeping lines can be causing the timing knock.

Not sticking injector, i think he answered his own question... timing knock

ahh ok
