Truck blowing white smoke on startup and hard rev
Hello
I have a 2001 f150 w/ 70k miles. I changed the oil w/ filter, air filter, and fuel filter about 300 miles ago. I've noticed every morning my truck blows a cloud of white smoke right when I start it up and goes away as soon as it idles. I figured it was condensation but when I got out to smell it smelled like a burning smell. Today it blew out some smoke on startup and it was 90+ degrees out. On the way home I decided to rev it up a little and it blew white smoke plus the tailpipe is now black on the inside. Doesn't smell sweet like antifreeze and doesn't smell like oil. Any suggestions would be helpful.
Also when I was reving it up today it made a squealing sound, maybe that was because I was using my A/C?

Welp. It's probably coolant or oil. You'll need to monitor the consumption of both. I see your in SC, possibly a lower concentration of coolant to water in your system since it doesn't typically get super cold. This would contribute to no sweet smell.
If you haven't changed you pcv recently, I would do so as its about the cheapest possible solution. Other than that, you're looking for a bad intake gasket, head gasket, worn rings, cracked head, cracked piston, etc.

I agree with Tackle. I highly doubt it being a catalytic convertor, as they wouldn't be "heated" at the beginning of an engine start cycle. If you get white, it is more inclined to be from the cooling system, rather than any other part of the engine. Hope that helps.
Good luck.

Thanks. I was actually just discussing the PCV valve with my father, not sure it's function but I will change it ASAP. Another interesting thing I have found is if you start it and turn it off, then start it right away it does not smoke. So I'd assume what ever is burning up is building up when the vehicle sits. Also considered a catalytic converter issue but no codes.

I've owned the truck since I bought it new in 2001 and have changed the oil every 3k. Also, for everyone else, the coolant reservoir is at a perfect level and doesn't show I've lost any. However it is a very dark blue color and smells like rubber. Had a coolant flush maybe 5k ago.

I asked about oil because if you had just bought it and were doing the first oil change on it a previous owner could have covered up problems with Lucas ect... But that is ruled out.
A few things I'm thinking.
Oil control ring problem leaves too much oil on cylinder walls, this oil settles puffs out when first started.
Fuel pressure regulator gone bad.
Minor crack letting water into cylinder that's seals up when running.
Leaking injector that's bleeds into intake.
Just thinking out loud. Has mpg dropped?
