Just wondering how many people have done Mikes crankcase vent. I knew about the vent problem and his inexpensive repair but put it off until my radiator looked like this;

So I cleaned my radiator, intercooler, engine...and added Mikes upgrade and haven't had a problem since. Also, my truck doesn't smell like oil after an oil change like it used to.

Regardless, my trans would never pull a trailer up a 16% grade. 9 is a pita as is is lol!Sent from my SPH-L710 using Tapatalk 2

I never tried a 16% with the trailer. 8 is maybe the most I have ever seen towing.

16% grade = 16' of rise in 100' feet of road.

Thanks for completely ruining my over explanation, lmao. Sent from my DROID BIONIC using Tapatalk 2

We work on 1.5 to 2 acre lots. 100 foot increments is about all we use. Keeps it simple. Funny thing is I dont remember seeing your explanation when I replied.

Man I have not read this thread for a long long time, I can't belive how elaborate you guys get and then add all that extra piping in the already busiest spot on the engine would drive me nuts to work around yuk yuk yuk.:2cents:The guy who bought the Walker airsep I had on my 02 loves it and I still like my garden hose approach dumping it out behind the engine., I even rerouted the one on my 05 as it dripped on the front diff housing right above the pinion by the yoke and made it look like I have a leaky pinion seal so I added hose to it and did the same as my 02 and ran it through the frame towards the back and out the next hole.

Bill, Would you happen to have a picture of the routing you took for the garden house? Curious to see exactly where you ran it. Up over the engine? Off to the side? Thanks

off to the driver side through the closest opening in the frame rail and out the opening just in front of the fuel tank and just let it hang out a few inches.

Be careful of the garden hose idea. I've had one report of a heater hose mod that kinked closed over time and blew the tappet cover gasket out and losing large amount of oil when it did blow out. Truck required to be towed for repairs..

Yes I plan on doing this. For now both trucks have a straight down pipe, but it messes up everything under there that you normally grab to help your creeper  move around,

Heater hose and probably garden hose to well get all oil soaked and a terrible greasy mess.

i converted to plastic PVC pipe 1/2" schedule 40

 

I dont care for routing over the top, I dont drive at 20 or 22 degree down hill slopes

Hi everyone, Newbie question here.

 

I have a 98.5 24v which has a cap on the front cover and a 12" hose coming down the tappet cover. The thing is i live in a association that is very picky about my driveway being stained. So with that being said i can't have any leaks on my truck, so has anyone tried installing a catch can at the end of the tapper cover hose? If someone has done can you provide the link or maybe pictures.

 

I recently installed an Airdog 150 and thought of maybe installing a catch can right next to it and route the hose all the way there to make it accessible when emptying it out.

 

 I was looking into this one, and having it mounted next to the Airdog under the cabin. Keep in mind i live in Florida and i don't go muding or anything like that, so i should have any problem with debris or the hose freezing shut.

I just added more hose and went to the ground

 

Be aware panic stop and steep slopes can and will push quart or more out yet. Makes to check you oil often if either condition occurs.

 

Vent pipe prevents these two conditions from happening. The worse case I lost a full gallon. Be aware...

before i did my mod, i was rock crawling in colorado and unknowingly dumped a gallon out the front vent because i was going downhill so steep, the oil light came on.

 

after the complete mod, ive had zero issues since, even in -17deg weather

I done the same thing and dumped over a gallon trying to get out of the forest with a load of firewood on my truck. Then another time I dumped over half gallon panic stopping on a grade to avoid hitting a deer. The fan slung oil all over the engine and everything in both cases. 

 

My design is from snowmobiles. You can roll the truck upside down and not leak at all. Being the end of the tube is higher than the level of oil upside-down. If tip it nose down steep the end of the pipe is still higher than the level of oil.
