What Joe P. Has To Say About The PCV Valve!

[MazdaspeedZOOM]

Here you wanna end the debate here is an e-mail from Joe P. himself sent to me when I asked him the never ending question about the PCV Valve in our cars and the benefits of the 323 gtx over our stock valve.

"If the 323 GTX valve is a one way check valve style PCV, it will work better
under high boost situations. If the stock valve leaks pressure through it
under boost, it will allow boost to pressurize the motor and possibly do
things such as push the dipstick out and such. I have not experienced any
of this, but that is what can happen if the info on the valves is true."
-- Joe

There you have it from the man Joe P. Now I'm sure what a lot of this means but I think this should help some people and hopefully give us some answers.

Good info -- always like to get his opinion on things.

Sorry to sound like a noob, but does that mean the new PCV valve is a good idea?? I've got mine sitting on my desk waiting for a free moment for me to install it...

The answer is in there.
Joe said, "I have not experienced any

He is not saying it needs to be replaced. He does not know if the info about it is true or not so he has not made a firm stand.
In essence It sounds like if nothing is wrong, it isn't goingt o go wrong. Keep in mind Joe had his MSP to over 15 PSi and had no issue.

I am not sure what the debate is here over the valve, it doens't say what is wrong with it only that if some info on it is true it ma casue a problem but not one he had encountered.

Well I think he is saying that in theory the 323 gtx valve would be a better one than our stock one, as it's ment to handle more boost and the construction of it being what it is.

In addition to my above post I agree with this post as well. Joe has not experianced any problems with his valve so he really can't say for sure whats going to happen.

I'm running 9.5 - 10.0 psi, and I have no oil leakage whatsoever with the stock PCV. All is fine. How long? About 2 months.

I changed mine because I plan on changing everything Mazda didn't do right. The PCV valve is one of them. I guess if you wanted, you could buy a couple stock valves and keep them around JIC.

What exactly are you "correcting" Dave?

What exactly are you "correcting" Dave?

Kind of what I was thinking. I live by the principle, "If it ain't broke, don't fix it."

Now there may be a guy or two out there that are having problems with their PCV valves. But if it where me, I would take it to the dealership and let them fix it. Let Mazda build a database on problems with the MSP so maybe at some point in time, they will come out with a TSB.

Seems this hole PCV fiasco is much to do about nothing. Or at the most, much to do about very little.

Intercooler? Replaced.
Radiator? Replaced.
Cooling line / Oil line etc.... Hose Clamps? Replaced.
I/C piping? Replaced.
PCV Valve? Replaced.

Sorry guys, My wording should have been different. I'm improving reliabilty. Upgrades that are significant to our ongoing problems.

Yes. You guys are right to say if aint broke don't fix it. As I have never experienced this "hesitation" or "stumble" I'm not really fixing anything. If the OEM part is flawed, or insufficient, I will NOT use it again. As I discover discrepancies in Mazdas design, I will in turn upgrade.


Rather than get into a situation where breakages may occur, I am taking preventative measures to keep this situation from arising.

That's all.

Okay, I see your point. Nothing really wrong with what you are doing. Didn't mean to come across as putting you down for changing parts.

 

[MazdaDryvr]

I was just looking for a list of things he was changing. Add it to my own wish list. I did have the dealer replace all the crappy spring clamps with the screw on type. What do you think I should do next Dave?

 

[MSPDAVE125]

Well we all know that this car suffers from heat soak. In fact anything infront of the fire wall is White hot. So here is my thinking.

A Bigger and better placed intercooler that actually gets air to it will dramatically lower intake temperatures. (We all know that). Now. This car runs hot! Very Hot. You've now ditched the side mount cooler. Pull it out along with the weak & tiny Radiator and get an Aluminium one and 1 bottle of waterwetter. If we drop the water temps, the oil temps will drop too because the MSP oil cooler uses engine coolant. Also the turbo will be MUCH cooler because our Turbo is WET (oil & water cooled) (DRY is oil only), and we have cooled both the oil and the water in this process.

See where I am going?

A very knowledgable memeber also mentioned to me to track down a scraped RX-7, not the last one, the one befor eit like the 89-91 or whatever. Apparently it has a VERY GOOD oil cooler that we can use to dramaticly lower oil temps.

Just thought I'd add that.

 

[MSPDAVE125]

Well if we could incorporate this cooler and re-route the coolant lines away from the stock cooler (jacket), we could inturn lower engine temps because coolant gets hot too right?

A guy I know actually made some power in his Miata by re-routing some of his cooling lines. He keyed on the intake manifold. Keeping the manifold dry was a big difference he said.

I heard that Ion has a FMIC kit that's good and that once you have that installed to put a P5 rad in. Does that make sense?

 

[MSPDAVE125]

I have the Ion kit. And I have the AWR radiator which is the full size 2.oL N/A Radiator.

 

[MazdaDryvr]

How much is Ion selling the FMIC for?

I think there is a thread here somewhere.
