Or so and now i have it and it smokes. After. I put my foot on the gas at frist its blue. Smoke Blue. Smoke frist then it teuns in to white smoke i need help
Blue smoke is oil burning and white smoke is coolant burning. White smoke usually indicates a blown head gasket.
What does Blue Exhaust Smoke mean?
Blue smoke is created by the vehicles engine oil entering a cylinder and being burned along with the Air/Fuel mixture. A small amount of oil leaking into a cylinder will create blue smoke out the tailpipe. Blue smoke is more often and issue in older or higher mileage vehicles.
Sometimes using a thicker oil can help, but in most cases replacing the failed gaskets and seals is the best way to insure the issue is fixed.
