volvo D13 oil separator has oil coming out from pipe

If you are trying to keep running this truck till you have cash to do a eng. overhaul you can try adding lucus or any of the oil thickeners to keep the oil in it longer, but a broken or worn out part in motor is starting to show

 

How many miles on the truck? At 450k ish I had to replace the crankcase vent separator assembly. I was losing a lot of oil but once that was replaced I didn't lose much of any between oil changes

Good luck

 

Can the separator unit be drained ????

 

I have a cat c13. My truck was doing the same thing. Took it to cat a month ago. I had a crack head. They did a platinum overhaul. But, before that I was using 4 to 6 gallons of oil between changes. I change my oil every 12k mi. If your fuel mileage is good and it's pulling. I would keep adding oil. It's cheaper, than a overhaul. Just my .02

 

One thought could be that your truck was one of the Volvo engines that had the bad valve guides problem. Usually the ones with the problem show up before 300k mi but you never know....

 

for a temporary fix you can take a 1 inch rubber hose and loop it around from the inlet to the outlet of your crankcase filter then just run a hose from the valve cover down i know its a redneck fix but ive done it to a few with 600,000 + miles and they are still running good. Those crankcase oil separators are like $600-$700
