my truck ran fine until I changed the oil... ever since I changed it the truck smokes white like crazy until I start driving. even then it's blowing smoke for a bit... what would changing the oil do that would make it start smoking so bad? weird part is it feels like it has more power now... Idk

WHAT DID U DO???!!! lol iv never heard of that. oil burns blue and clears up after a little while (unless your rings are toast) white smoke is usually coolant due to a faild head gasket and smokes consistantly. but it seems odd that it would decide to go right after an oil change. and even odder that it has more power. normally if u have a blown head gasket (or burning coolant for any reason) it would normally run like ass. i would run it for a little bit and see if u have any coolant in ur oil and vise versa. also if u keep driving it, keep an eye on your temp guage and coolant level. if u loose coolant and cant find out where, see if your oil has coolant in it, if it does, its a head gasket. if it overheats and u let it get too hot u might crack or warp the head and or block so be careful out there and good luck

That's actually a really legit question.
WHAT DID U DO???!!!
lol.
Did you change the oil while the engine was still hot as buggery and then pour really cold oil in and magically crack the head?
Did you pour oil in your coolant and coolant in your oil?
I know you didn't but what grade of oil did you use etc.

lol used catrol 10 40 and a new filter... I've done hundreds of oil changes so I really don't know how I would mess it up lol I checked the oil/coolant and it's all good (right color and level), temp Guage is right were its always been (just past half way) no blue smoke... which is confusing me even more that it's white... and yeah, it feels like I gained at least 10 hp! lmao i have no idea what I did... smokes a comical amount of white smoke when I first start it up in the morning and it idles really high, I start driving down the road and about half mile later there's no more smoke and she's running like a champ... I just passed emissions with flying colors last week, there's no leaks anywhere on the truck, all fluids are good....... what the hell did I do? lmao

Jiffy - I don't think you did anything wrong at all. In the recent cold weather here, mine smokes a lot in the morning when the outside weather is like 40F (it's pretty impressive), doesn't do that on 60F mornings, that's water vapor.

Also, it's possible that there was either straight weight oil in it before, or just that the more-volatile components in the old oil had already burned off, that could compound the observation.

I use straight-weight 40 oil year round here in the B2200.

And it's possible that one oil v. another could smoke more. I think most of the smoking will be gone in a few weeks and as temperatures get back to normal. At least you don't need emissions test again for two more years.

that's what I was thinking. It only smokes when it's cold outside. When it warms up a bit ill see if it's still doing it. runs great otherwise

That's right, don't panic.

I'll look for an outside passenger plastic trim part for yours next time I'm up in Prescott Valley. How do they remove (my Cab Plus doesn't have those).

that would be awesome! all the trucks i find around here are cab plus models... i believe on the inside b plllar there is 3 or 4 bolts you have to use a long deep 10mm socket i believe. if theirs anything else up there you think i could use give me a call while your there, would gladly pay you for your help

There's a '91 B2600i and an '89 B2200 automatic up there, both regular cabs, so likely one will have a decent one. There's supposedly 2 others.

Might be in about 10 days, let me know.

Needs to be stuff not to involved to remove like that side post trim. One "parts grab" took me 1.5 hours, but the guy needed a favor, and it was Christmas, so was OK.

On the upside, if it turns out to be water vapor you'll get to meet me!
As I will have to fly over and slap you for being silly.
Only lightly, and you get a nice dusting of icing sugar afterwards which the girls all love.
