Hello im am new to this site and looking for opinions about my issue. ill just start from the begining. About two weeks ago i changed my oil and put on my new intake. then drove from texas to missouri everything was working fine and dandy. i went mudding in missouri and notice a power loss, so i cleaned my air filter. on the drive back to texas i could still notice the power loss as well as my mpg has gone down. the last two months here in texas it has been 100 degrees plus and the last few days it has cooled down to the low 90s high 80s thats when i noticed the white smoke. it's not just at idle, i excelerate and i cant see the cars behind me due to all the white smoke it was bad yesturday morning but not so bad in the afternoon. the coolant level is fine,the oil level is where it needs to be, i didnt see or smell any diesel in the oil, but the exhaust smells a little like diesel. what can i be looking at here? headgasket, pistons, injectors? I aprecitate everyones input. thank you in advance.
