View Full Version : Breather filter?

02-05-2005, 05:58 PM
i broke my bypass tube thing that goes from the valve cover to the throttle body or wherever. are those breather filter things a good idea? or should i just wait till monday and get a tube from toyota? if i get a breather filter, do i need a certian kind of one with an oil catch thing or what?

I would just go to an auto parts store and get a length of rubber hose. It won't be molded like the current one, but it really doesn't need to be.

What would a breather fitler do? Would it be any better compared to the hose that's already there.

doubt it.
i just wrapped some electrical tape around the crack for now. the hose i got is bright orange, so im painting it

Doesn't that setup help relieve internal engine pressure (hinders gas flow)? Wouldn't replacing the hose w/ a breather filter hurt the engine (put pressure on internal parts and gaskets)?

I think it does something similar to a pcv valve, recirculating gases back through the intake to be burnt again to keep emissions down. See where the hose goes back in on the t/b housing? I have a breather on all my older cars that have pcv's and it actually helps but I have'nt tried it on this one.

*It is the pcv. The S series engines don't have a valve, just a hose.*

It relieves crankcase pressure, but also lets oil and all the crap in the crankcase into the intake tract, all for emissions.
If you plug it up, it will cause problems, but as long as it can still vent, it will be ok.
Best thing to do is get a catch can, that way the intake will suck out the crap, but all the crap gets caught in the catch can instead of the intake.

One word of warning on the breathers, I put a "autozone special" on mine, and blew a hole in the end after a couple of months....
So be careful where you get it.

Great info, thanks. Tell us how you hook the catch can up and any other details you can think of, like the best place to get one. Seen 'em on eBay for cheap.:)
