After I told the guy at the machine shop that I was using 20over gapless piston rings from Total seal, he told me to some how disconnect the PVC system, or it will end up sucking oil right out of the engine. Or, he said to somehow restrict it so that it doesnt suck so much air (put a thick bolt with a whole drilled into it in the line). Has anybody experienced a problem like this with the PVC system in our cars and with gapless rings?
