new user to this site and new owner of duramax question is. ive replaced my injectors and now i have a new problem i have oil and fuel coming out of a tube on the front right corner of the block is this a leaking injector or do i have other issues. this tube is somehow connected to the crankcase but with the limited area you cant see where its connected but if you use a blow nozzle and blow air into the tube with the oilcap loose it will blow the cap off. if it is an injector how can i tell which one it is i replaced all 8 of them. in reading all the posts i am impressed with your site and look forward to future visits to help get this truck back to its original reputation.

 

You have a leaking injector, find a scaner than can read injector balance rates, that will tell you which one or ones are leaking, dont drive the truck any farther than you have to, the lack of oil will be hard on bearings etc

 

you have oil leaking into your crankcase, the oil/fuel your seeing is coming out the crank ventilator. check your oil it probably smells like diesel.

fuel can come from all kinds of places, bad injector, broken return line seal or corrosion from the injector/steel line connection.
