I read about putting SeaFoam in a gas tank instead of the crankcase because it takes away the carbon. I also read that is not necessarily a good thing in older vehicles because it will cause older motors to burn oil.
I put SeaFoam in my gas tank and now my truck blows bluish smoke on startup.
I believe that prior to doing this my motor was already burning oil. I also believe it has a rear main seal leak.
- If I chose to get a rebuild kit and rebuild my motor, do you think this will help my oil burning problem even after I removed all of the carbon?
- Do I have to rebuild my motor to fix the puffs of bluish smoke that come out of the exhaust pipe everytime I start my truck?
- Is a rebuild my only option here?
