For quite a while my "check engine" light has been on and once in a while when i first turn my truck on white smoke comes out of the muffler smells like the fuel isn't being burned properly. i already changed the catalytic converter and the oxygen sensors. it was good for about a week, then smoke came out again and "check engine" came back on. can anyone help me out and maybe know how to fix this problem?

thanx

 

White smoke usually isn't fuel related. My truck blew white smoke with a blown headgasket and was spewing burnt antifreeze out the exhaust.

Run by Autozone and have codes checked.

 

already gone to autozone to check it out but they just keep telling me "oxygen sensors" or "catalytic convertor" but i had asked my dad not to long ago and he said it was the head gasket. any idea on how to replace that? or the price on it?

 

Heads have to come off. If you take it in you could pay maybe 400 and up to get it fixed.

 

damn bro. any idea on the pricing of the gasket? like a more or less?

 

gaskets cheap labor is the pita

 

I'd get all Felpro products which cost about 15ish a head for the gasket plus 20ish for new head bolts.
