Diff (and other) Breather Extensions

[Fisher23]

I do not see a breather on my starter motor.

I do wonder if there is a breather on the transmission behind the torque converter. My dodge ram diesel had one there that I had to seal up.

Here are a couple pics of a new OEM starter for a 2013 5.7 . Been procrastinating and dragging my feet on the install, hoping to get at least another 15-20k before replacing. It has the drain hose looking thingamajig as mentioned above.

The starter for the diesel which is what VooDoo has has breathers.

Interesting. It also has what appears to be a much larger motor, which makes sense due to compression ratio. I wonder whether the breathers are related to that? Like an air space over a certain volume?

If the breathers here were intended to be more off-road resistant than the drain wouldn't other breathers be different too?

First page of this thread has pictures.

I’m looking at extending some of the breathers. I read above in a post by @VooDoo2 that there is a starter breather. Can someone with a gas engine US spec 200 confirm there is a starter breather? I’ve had my starter replaced, and I bought all the parts. I don’t recall seeing any kind of breather connection on the starter itself. But I did not do the install, so maybe I just missed it.

Diesels have 2 breathers, Petrols have 1 (on the starter)

This is them untouched. (diesel of course)

Anyone got a picture of these on a US spec gas 200? I can not for the life of me find the trans/transfer breathers. My exhaust pipe and manifold is in place and I don't want to remove the heat shield just to find them but is that the only way to get access to them? If I drop my skids will I be able to get to them?

My transmission was replaced in 2018 and now I'm wondering if maybe they could have forgot the breathers?

That picture looks pretty much the same as my US petrol as well. 3 (I think 3) tubes coming up the firewall behind the engine, on the left of the transmission.

Hmm. I see these tubes but I thought they were brake lines.

Are you saying the breathers are up in the engine bay on the fire wall?

Thanks man! Looks like I can get to the from the top. Makes me wonder if they really need extension.

Well, after at my actual truck, I don’t see any way to get to them from the top without removing the intake manifold. I also don’t think you can get to these breathers from the side without removing exhaust pipe.

Has anybody extended these breathers without removing the exhaust our intake?

Had the 200 up on a lift and was an able to at least put my eyes on the tranny and transfer breathers. I do not see any possible way to access them without removing the intake and go in from the top. You might also be able to get there with the exhaust manifold and starter out. Unfortunately, I didn’t think about this when I did the starter.

After seeing where they actually are though I’m not that worried anymore about extending them. They are higher than the shock towers and about at the valve cover gasket level. You’d have to be in water higher than the top of the wheel well and I’m not willing to do that regardless of the breather location.

Also I bought a set of the breather valves because I thought I might want to replace them if extended them. The diff breathers are one way check valves. They only let air out. While it doesn’t hurt to extend them it shouldn’t really matter as they shouldn’t suck any water in. If you raise them AND use the ARB style filter instead of the OEM check valves, that might be better than stock as the ARB filter will allow air to be sucked in preventing the diffs from being at vacuum as you cool them during a water crossing.
