Hello, I have 85 Chevy C10 2wd, 305 motor.
I was starting to have a problem with white smoke comming from the tail pipe. I've been told its the piston rings. I figured the motor can wait to be overhauled till later this year so I went and got a bottle of NoSmoke NoLeak and added it after I changed the oil. I also changed the pcv valve. I followed the directions on the bottle. I drone the truck for about 15 miles and then parked it. I went to drive it yesterday and the white smoke is now pretty much gone but now there is alot of black smoke. Even sitting at idle you can see the black smoke puffing out. I never had black smoke comming out only white.
Anybody have any ideas what could be the problem?
Thanks in advance!

I know what white smoke means. My question is why did the white smoke stop and now the smoke is black?

You've already been told a few times what the white smoke was, the black smoke is usually from running rich, unburned fuel, you might want to try some Engine Restore additive or Marvels Mystery Oil to see if the rings will seal back up a little.

White smoke is often anti-freeze or water vapor, no longer oil. Oil smoke is blue, or has a bluish tinge. Whomever instructed you piston rings isn't the guy to flow to for suggestion. i'm rather advantageous you have a coolant leakage problem. Has the truck run warm? The symptom you describe is in lots of circumstances a blown head gasket. ninety 9% of time it particularly is what white smoke shows. examine your oil- it would desire to be milky white, or open radiator cap- you will locate oil on the rubber. The black smoke is an indicator of an engine working too prosperous, in lots of circumstances a choke out of adjustment. sturdy success.

The white smoke is usually water or coolant in the exhaust. This would indicate a head gasket problem.

you know what the white smoke is, so we won't go there. the additives may have stopped the white smoke problem, only to show you that you have another problem, with rings or valves. at least your car isn't prejudice. a rebuild is probally the only good solution. for now you can try some noblacksmoke additive.

white smoke generally denotes a blown head gasket...are you using small amounts of coolant? sweet smell coming from exhaust? if so it is a head gasket...blue smoke is oil burning..the black smoke is probably from the no smoke cleaning out converter and exhaust pipe...305's are known for cracked heads and blown gaskets...you can drive them for years with either...
