here's how a PCV valve works:
http://www.stealth316.com/images/pcv-operation.gif even though boost it acutally pushing the plunger closed....somehow a lot of valves still leak...Get a factory part...I had to buy 3 NAPA valves to get one that I couldn't blow through myself. |
well you learn something new every day! and here i was thinking my engine was safe with its little bit of boost. guess i better look into this a bit more. do we have these pcv thingos on our aussie engines? i've never heard it mentioned before.
|
do you have emissions there?
|
yeah we do.
i just had a look, it's there. it has "bp05" written on it. |
How much metal was taken off of the cam? The material used to make cams turns into a nice powder that is just perfect for clogging oil passages and spinning bearings...
|
No metal removed, just a nice scratch. I'll go for a drive as soon as I get home and pass the word on how it goes. I'm assuming it's not gonna smoke anymore.
Additionally, I didn't find any of the plastic body of the PCV valve. I guess it probably got chewed up a little and made it's way down into the oil pan. I'll check the oil real careful next time I change it. I'm not worried about it. |
Damn one more reason to not run a PCV boys and Girls. :gay:
|
Well thats better then a blown Trubo :)
|
What do you do to lose it?

OK, guess I'll go to PepBoys and pick this up. And some colder plugs.

^If you just block off the port, usually the vacuum from the breather line going to the intake on the opposite side of the valve cover is sufficient to keep good flow... but I'm confident the new 323GTX turbo-specific valve will not fail.
|
wow that's nuts, i'm glad i've got the metal gtx pcv in there
|
Can't we put breathers on both?
|
I suppose you could, but then there's nothing helping oil drain from the turbo. I don't know of anybody who will tell you there's anything to gain from removing the PCV valve except that now you don't have worry about it breaking. Quite a few guys put a filter on the intake breather line, but other than aesthetics or not having to plumb the intake for it, there's no reason.
Running the breather ensures the valve area and crankcase are always under vacuum and you have good oil drain from the turbo. |
dang...add that one to the parts list....
Where did you get your PCV at? A dealer? |
totally dealer.
look up a 1988 323 "Turbo" PCV Valve. i dont know if it has a p/n. |
should be: E301-13-890A
|
It's made by Purolator. I got it at Advance Auto Parts... lots of other Mazda's seem to use the same piece. Something weird was that 90-91 and 93 Miata's use the same part number. 92 uses something different, and 94+ use yet another part number. The 323GTX one was like PV-1014 or something and didn't share with any year of the Miata. I'm sure you can find them at any auto parts store.
|
I decided never to buy pcv valves from napa or autozone anymore...took me (3) to get one I couldnt blow through.
I'm still going to be trying a brass check valve in-line with my pcv valve... |
How the hell did it the guts make it through the baffles in the valve cover?
Wacky stuff. +1 for getting the PCV valve from the dealer. |
