Engine/Transmission (1998.5 - 2002) blow by breather hose?

[Baron]

Crawling under the '01 rig finding oil spray coming from some rubber hose assembly that ends in a rubber resevoir full of oil. This attaches to the timing cover or gear cover on the front of the engine. What's going on here . How do you clean up this sitch? thanks baron

It's the blowby catch bottle.



Your choices are:

1. Clean the bottle every oil change. Put a paper towel in the bottom of the bottle.

2. Extend the hose to under the transmission and lose the bottle.

3. Extend the hose straight down and relocate the bottle to near the sway bar.



I chose #3 because in the stock location the fan seems to pickup the vapor out of the bottle and blow it around. I made a larger bottle out of an asprin bottle and put a couple of paper towels. Used a 3/4 inch hose union (home depot variety) and some 3/4 inch heater hose to extend the hose, and put a zip tie around the end of the hose to hol on the bottle cap. Just unscrew the bottle, clean it up, and put in a new paper towel. Now the better half lets me park in the driveway again.



By extending the hose back with no bottle (#2), you run the chance of the hose freezing up in colder climates, and also still get oil vapor over anything aft. If that hose ever gets plugged you will be blowing engine seals.



Maybe others have some ideas.

I basically chose #3, but did NOT re-install the bottle. I only have drips after a long trip and it has been this way for over a year. I don't like spots and it has been very clean this way.



Cannot complain and my engine is much cleaner as well. No bottle to continually mess with either. I just added about 18" of heater hose and a male to male connector. Only had to zip-tie it in one place I believe to secure it away from the fan.

There's an option #4 which I chose, but an expensive way to go - it's the Enviroguard system sold by Fleetguard. Cost me around $250. No drips or future maintenance to concern yourself with.

#5,



I ran mine to the sway bar and zip tied the foot part of a sock to it. The oil blowby drips into the sock (a drop or so / week?), but the oil will also wick UP the fibers of the sock. 6 months later about 1" of the sock is dark, probably change the sock 1 / year.



I did not like the oil spots on the driveway

Not sure how it would work for y'all in the northern climates. If the sock froze, the blowby would probably overpressure a seal somewhere. Not a problem in florida.

But it could still freeze on you. It is WINTER Haven afterall

There is a technical service bulletin on this, that I had done to mine which relocates the breather from the front of the motor to the side cover on the motor. This includes a large hose that goes below and behind the motor. The hose does tend to drip a few drops on the driveway when sitting but is not making a big mess on the motor like the original set up did. I could put a bottle on it and solve the drip problem.



The TSB had to do with the motor losing oil when the truck was at an extreme downward angle, like when four-wheeling.

I ran my hose all the way back to frame rail pararllel from the skid plate using heavy duty high temp 3/4 hose. I have talked to guys in cold enviroments and there has never been a problem with it freezing up, just make sure there are no major bends or sages in the hose where it could jam up. i live Conecticut and it gets dam cold up here in the winter. i notice the replys from members talking about it freezing come from warm enviroments. i also got sick of the mess it made in the engine compartment. since i moved it, my engime has stayed much cleaner and i have very few drips on the driveway

I did a solution for my Oil Vent... #6 I guess you'd say.....



The solution is to make a vent on the valve cover like the N-14 Cummins has on the big truck I drive.



First I ground down the rear of the two raised bars to make a flat surface for the grommet.



#ad




Here are the parts I got at Auto Zone. The item on the left is a GM oil filler cap and it has a out tube but is hidden here... has a baffle and sponge that will keep any oil in on splashes. Part Number is #8075 The grommet on the Right is one of the "HELP!" items part # 42306 "oil filler tube grommet"... . and not shown but is in lower pics is 5' of crancase hose



#ad




Then I started drilling. first I drilled a small hole, making it bigger and bigger till I had 1 3/8" opening for the grommet.

#ad




Pic of it installed on the valve cover. I had to remove it to put the cover on the truck.



#ad




After I put the cover on, it was easy to put the grommet on then the breather on. it is right at the padding... just right..... attach a hose, route it down to the side of the engine at the engine mounts. and tied the end to the plate for the axle disconnect wih an angled cut on the hose so wind will draw the fumes out through venturi effect.



#ad




Then I had to block off the original hose so I found a plug and used a piece of the original hose to block off any oil to want to get out.



#ad




Ran the engine and no leaks and it vents just fine. now I can go out and go offroad with no worries.

This is sort of a dinosaur thread - and keeps resurfacing on a regular basis - I guess Eric and I need to do a "file save" on our respective "cures" so we can save re-typing them each time the Vampire again rises from the dead!



My fix is #3 - I drilled lots more holes in the original bottle, covered the outside with an old sock, extended the hose to the front swaybar, and change the sock every oil change.



#ad




No more oil drips ANYWHERE - mot in my garage, not on my driveway, and the COMPLETE underside of my truck looks like THIS:



#ad






Yeah, you CAN spend lotsa $$$, you CAN remove valvecovers and grind holes in them - or buy fancy commercial cures, but why? What ELSE ya gonna do with yer old socks? :-laf :-laf



This 15 minute, 50 cent fix sure works for me... Oo.

I don't want to get rid of my leaks under the truck, they keep salt off in wintertime, lubricates chassis,a nd keeps rust off.



It's Minnesota here, more salt in winter than Salt Lake City everyday... ... . God bless my leaks... . Oo.
