But there is a lot of (blow by) white smoke comming out of the breather. I am wondering if it could be because of the vacuum pump leak? I did the oil cap test and there is no air or smoke moving the oil cap. Truck has 240miles and.

I changed my pcv valve and the problem went away. I assume that it was caused by the pcv being clogged. So, the normal crankcase fumes would build up and the gases could only escape through the breather.

Re: Smoking Crankcase breather The smoke is blueish to white and has an oil smell to it, the motor starts very easy and runs good. I ran it with a bush hog for about minutes and it ran great with good power. Hours were 1and it was it’s third oil and filter change. I did notice it was starting to smoke a bit at that time. I drained some liquid from the muffler thought that might have been the problem.

The engine runs now and sound very strong but my problem is that alot of white smoke come out from the valve cover breather on the left side at the right side also from the valve cover plug i also do have a pcv valve and its installed but not the line yet, because i need to drill a hole in my intake manifold first, i run a 15w oil, the guy.
