    Just overhauled a d13. Ran good 700 miles and then it started shooting oil out the breather tube. Losing about 3 gallons every 100 miles. No active or inactive codes for high crank case pressure. Only active code is p04db00 which is for ccv disconnected. I’m 99% sure the breather has failed internally and is causing all the oil to leak. Any opinions on that?
