extended breather lines

[SW86]

has anybody extended any of their breather lines??? i like to play in a lot of deep water and I'm tired of having to change out oil all the damn time.

yeah i figured it was but its still slightly raining here and its just sh*tty outside. i wanted to get a head start on it if i could so when i go to do it there won't be any issues. ive been browsing the net checking some stuff out :thumbsup:

I'm assuming this is for the '88 with the AW4?

 

The trans line is connected to a small bracket on the upper bell housing bolt with a slight turn down. You can connect a hose straight to the end of that and bring it up to where ever you would like. The transfer case line is fairly easy to get to but it's on the top of the transfer case. If you're having issues getting to it, you can remove the transfer case shifter and it's real easy to reach in and get. You can either find the end and extend it or just run a whole new line, it's just on a little L shaped piece of metal coming out of the top of the transfer case. The front diff is real easy, I'd replace the whole line if I were you as hose is cheap and yours is probably deteriorating. Those three can be run to the hood or you can run them to the air box if you have a snorkel to make them really water tight.

 

The rear axle is a little tricky to find a place to run it to. I ended up running it into the frame rail and didn't have too much of an issue with it since I couldn't find a place to run it up higher (this was on my old Cherokee and haven't had a chance to run one on the Comanche yet so you might be able to find a better spot).

 

If you really want to go into deep water, invest in a snorkel (home made or pre-made, just something that is water tight). You will also want to seal up the engine then. Make sure all the vacuum lines are sealed tight and seal all the electrical connections. Make sure you have no leaks from the gaskets (a leak going out will allow water to leak in) and you will want to seal up the distributor (I never had an issue with the distributor in my Cherokee but have had friends seal it up with permatex, drill a hole in the top, put in a hose connection and run the vent line to the air box). You will need to vent the brake master, power steering pump and need to seal up and vent the alternator.

 

If you really want to get extreme, you will want to seal up the holes in the firewall and put thicker weatherstripping on the doors so they seal tighter. You will need to seal up all the holes around the shifters with sealant as well as the e-brake line going out the back of the cab and fuel wiring going out the floor right behind the drivers seat. You will also want to swap out the factory drain plugs with rubber plugs that are a tight fit, that way if you do take in water, you can pull it and reuse it (the factory ones are metal tin can top looking ones that never seal right after being pulled once).

 

I think I got them all...Not sure how extreme you're going but that's most (if not all) of what you need to worry about.

Thanks for this ill be saving it to my book marks. I know that Ive already extended my rear end vent hose into the bed up by my tool box and this was going to be my next project. Thanks for the info

Would it be okay to connect a couple of the breathers together into a bigger hose? That way I won't have four separate breathers running up the fire wall When I extend mine.

 

Thanks

It shouldn't be an issue. Just keep an eye on it every now and then (maybe a few times a year) just to make sure that no fluids are being kicked up the tubes.
