Question about Cars & Trucks
Every once in awhile i would smell oil burning, under carriage soaked in oil. went and got oil change done seemed fine then took for a drive stopped at corner store and smoke was coming out from under hood close to windshield was oil smell no fire just burnt oil, a guy asked me if everything was ok, it was dark out so he didnt see anything out of ordinary, said it sounded like crankshaft or case breather tube, just wondering if that is what the problem is or if is pcv valve and crank case breather and how expensive it would be to fix, can i fix it myself and what parts would cost
Pcv valves allow oil fumes to be burnt through the motor so the smoke would unlikely to coming out from under the hood.. To get you problem there has to be raw oil moving onto a hot surface such as an exhaust pipe. Check all obvious oil leak points such as front crank shaft seal behind harmonic balancer. check transmission oil cooler lines if fitted. check rocker cover gaskets as they can leak small amounts of oil directly onto the exhaust manifold mostly from the rear of the head. check for oil leaks at the rear main seal at the mounting cover. finally if the pcv valve is faulty then excess ive crancase pressure would have pushed the sump gasket9 or both front and rear seals) out of place and the oil again would be getting to the exhaust pipe.You say you have just had an oil change done check to see that the sump is not over full

Did you put Valve seals in the head???
Other than that the PCV is a good start...
But it sounds like the oil rings on the pistons to me.
