    Gu patrol problem

    Hey guys looking for some help I’ve got a 1999 rd28td Nissan partol what is breathing lots of oil and air out of motor when cap is off have ran pressure test on
    cylinders and is all within spec have tried fitting catchcan and top end has been completely rebuilt it is still breathing shit loads any ideas what could cause this issue? Car also has possible injector and pump issue blowing lots of black smoke and gets warm when you reach speeds of 120km but sits normal at 100km any ideas what to look at not worried about injector and pump issue just why it is breath so much thanks

    I could be way off the mark here, never having owned an RD28td - but I'd wonder if it has anything to do with driving it at 120kph. @mudnut will know if that's reasonable for this motor, but I'd imagine it'd could be revving it's nuts off. The black smoke may simply have the same cause - heavy throttle foot. As far as I know these revvy motors were no speedsters & it may just be that you are asking a little too much of it???

    I think the crankcase is always under pressure when running, so removing the oil cap simply lets the built-up pressure out, fumes and all. When it comes out the normal crankcase vent, the Provent catches it.
