    Hello. Hope everyone is having a great weekend i have a 2013 volvo with the d13 engine. I changed the crankcase breather twice and the sensors on it. It leaks oil from the tube almost a gallon every 200 miles the truck did a outrage around 90k miles ago and it has a new turbo what should I check it does need a valve adjustment

    Remove oil cap and see if you have excessive blow by.

    Also make sure oil is not over filled, I’d think that could cause it to leak too.
