Oct 6, 2016. yes it can cause smoke if the gasket is bad it will leak oil, the oil will run down the side of head & onto exhaust manifold where the heat of manifold will burn oil causeing it to smoke, if its smoking out the exhaust pipe you have something else wrong if valve cover is leaking the smoke will be coming from under hood while the motor is running unplug the upstream o2 and see if power increases. 2. in park at idle, revving the engine through the rpm range will show roughly a 10% discrepancy between the desired and actual fuel pressures, the actual being lower. Sorry I had to do an egr core. as you describe though, lack of power and heavy smoke is a cause of a few things, plugged air filter, very dirty mass air flow sensor, exhaust gas recirc valve failing allowing uncommanded exhaust to enter intake, under boost, this open egr will also dump boost pressure to the exhaust, hense loss of power and more black smoke. Stalling: If you are experiencing the stalling of your 6.0 (usually at low engine speed or idle) this is likely because your EGR Valve is stuck in the wide-open position, allowing exhaust gases to constantly flow into the intake.
