Alright... I called Mazda (because MAzda has ridiculious prices) and this is what i got...

I am about to do a hose job with silicon, and I read the guide that "Dave" gave on his website.

Replacing what I need to replace would cost me about $500, and I am saying screw that..... here are the prices I was given:

Throttle Body Gasket - $21.13
Throttle Body O-Ring - $23.25
Extension Manifold Gasket - $13.50
Air Control Valve Gasket - 12.25

Small Diameter Check Valve - $44.38
Large Diameter Check Valve - $36.41

Considering you have several green/white pills, replacing them would be off the wall expensive. I figure I may have a few I need to replace... where should I get these from?

Thanks a lot...

Try an autozone, just like the universal O2 sensor.

 

High Temp Red RTV from Autozone: $3.95

As far as the check valves, put up a "want to buy" thread in the forsale section. I'm sure theres plenty of guys with single turbos who have all the stock pieces laying in a box.

His prices will be about half those...

 

Mahjik has it right. Call Malloy. Around half price & free shipping too.

 

You can get some really nice metal check valves from McMaster-Carr for around $8ea. Can't remember the part number off hand though...

 

I read somewhere that those HELP! brand check valves work just fine, and are like $3 each from Autozone. Haven't tried them though.

 

I have to disagree with you here. I destroyed two of them within 5k miles. They work okay as a temporary fix, but they'll eventually die.

 

ive used the HELP! check valves, and they work fine

 

I've got those from auto zone. 2 years still holding.

hmm... cool deal. Glad you guys have some that are holding up. Maybe I just got a couple out of a bad production run or something. Oh well, I upgraded to some high strength metal ones from McMaster. They definately aren't going to break on me anytime soon (course, they are a bit more expensive. But hey, they're still cheaper than the Mazda OEM ones! )

 

What is the size on the large and small check valves?

I know the 4mm hose has to fit around them... so if i go into Autozone or wherever... what do I ask for?

I am going to need a few of them anyway...

 

You can also try Mazdaformance.

 

Or you can go to NAPA and get them to look up a quality check valve that is the same size. I ordered 3 or 4 from them for like $3 a piece, still working fine almost 2 years later.

McMaster-Carr sounds like a good bet, internet and prob a little more durable, you just have to make sure they have the smae closing sensitivty as the stock ones.

Don't use RTV, that stuff sucks. Go spend and extra $8 and get some Hondabond (one of the few things I would buy from them). Waaaay better than any Autozone RTV and just as god as Mazda's at over half the price.

 

My question is.. what is the 'correct size'

Say I just walked in and told them I want a check valve.. I need a size for the large and small...
