crankcase vent problem

[F350plusjd]

This summer I installed a crankcase vent kit. I used all of the 16 foot hose that was suppllied with the kit, which reached back to the rear axle. Worked great until December 14th. I live in Minnesota and the moisture and oil sludge in the hose froze causing back pressure in the engine. I drove about 10 miles before I noticed the smokey exhaust coming out of the truck. Shut it down and determined the problem. The result is oil on the firewall behind the turbo and down the back of the motor and under the truck. I cut the hose so it is much shorter and started the truck and let it idle until it warmed up. The crankcase is venting out the hose as it should. The truck seems to run fine and the exhaust was clear. The turbo has boost. I have not driven it down the road yet. I need to clean the oil off and then top off the oil in the crankcase.

My concern is did I damage the seals in the turbo? Will it continue to slowly leak? I was thinking I would clean it up and put it back in service and keep a close eye on it. Any opinions?

welcome to the .org also did you find where exactly the oil was coming from this happened to my buddie and all the oil came out his dipstick tube. everything else was fine and he has not had a prob since he fixed it.

No oil came out the dipstick hole. All the oil came out around the turbo. Some aroung the flange of the exhaust pipe connection into the turbo. Some around connection of up pipe to turbo.

my opinion is that this mod does absolutly nothing to improve engine performance or longevity and just presents potential for problems. I would like to see you hook it back up to stock.

You are correct this mod does nothing for performance. I thought it made sense to keep the oil vapor and heat from the crankcase from going into the turbo and intercooler. Right now I wish I would have left it stock...

Well, I would just change it back.

this mod makes sense if you are constantly blowing off intercooler hoses. i haven't had a 6.0 without it that hasn't blown the intercooler hose off, usually when i'm pulling a trailer in traffic. when that happens to you a couple times then the ccv mod makes perfect sense. i've replaced hoses and clamps and they still blow off. the sound alone scares the sh_t out of you. and losing all power. plus gumming up the intercooler and lines with oil. i can't see upgrading an intercooler if you are just going to fill it up with oil. all the fords i have ever had and fords that a couple of my friends have had do it. i use the racor filter but on some of my other trucks i've ran it over the brake booster and to the ground. i live in wyoming and have never had any issues running it straight to the ground. with the mod done i have never blown any hoses either. that's just my reasoning for the mod.

While it may not provide any performance gains it does clean up your intake. Maybe you like to see your oil soaked boots collecting dirt and looking all nasty, but I don't ! The problem is the type of CCV mod you performed allows for to many low spots for oil to collect. Did you route the line over the brake booster first? This is critical to allow the the solid oil vapors to drain back into the crankcase. I have researched this CCV problem for over 3 years now and I manufacturer what I feel is the very best CCV mod out there with not one complaint. Our trucks are very sensitive to backpressure and many of the DIY and junk sold on Ebay cause way to much restriction on the block. Your seal may seal itself back or may not, clean the area and keep an eye on it. If you want more info on my CCV mod just let me know.
