One-way check Valves and where to find them.

[preludeachris]

So on my adventure to try and put a check valve back into my break booster line, I had to "jump" through a few hoops along the way. My first stop were all the big name parts stores, they had check vales but most were the wrong size or they had to special order it. Well call me insecure but I really just don't trust those little after market air valves, I want something that was designed to be in the booster line. So my next stop was the dealer part store, Chrysler couldn't help me and the closest Mitsubishi dealer was 150 miles away...So I called ...yes they knew What i wanted and the fist time I talked to them they said no problem. Next day I get a call and I hear the dreaded words "Part Is Obsolete" apparently after ten years all parts are obsolete(didn't know that)....great just what I wanted to hear. So my Final stop was the Junk yard (which I hate going to because usually I have to deal with over priced parts and A**hole parts dealers) I check ALL of the eclipses they have in the yard and.... nothing most were non turbo or had no motors at all ....but long behold (and not to brag) but Honda comes through again...and I see a check valve in the booster line (pic below) and I grab it ...so then I stared checking all the cars I found 3 more accords and 2 300ZX's with check valve in the booster lines...I don't take chances a take them all. They all look like they fit 3/8 line so I going to buy some more rubber line and hopefully my mystery "humming" noise will disappear. So long story short, My advice to you if your looking for the check valve that goes in your break booster line try your local junk yard first!

ps. don't be afraid to check all the cars

PCV is different, I realize not by much and it would probably work but like i said I don't like taking anymore chances than I have to.

Yeah I checked up on those at the part stores..they were just like those ones that you have but most were to small and I just ... dont trust them? how often do you have to change your out?

Typically you dont need to unless they stop working, and you will know when they stop working. When I first bought my old Talon, If I went from WOT in boost to slamming on the brakes, the pedal was solid as a rock. Someone at some point had replaced the booster line and did not have a check valve in the line. So my booster would get...well....boosted
So I had to scrounge through junkyards until I found an unmolested booster line from a 2g turbo.

ok maybe I was a bit paranoid about the plastic valves but hey....at least someone can know ...plus I think the check valves I have seem to flow better...but hey if it works ...it works... Im just happy I dont have that crazy noise going through my break booster anymore and Im happy I didnt buy a new turbo either
