Replaced my PCV valve today. The "old" one had no valve in it at all and the OEM replacement does, obviously.



If it isn't normal, why would someone put in a piece like this and would it cause any damage?

"Old" PCV valve. This was the best way I could show that there was no valve in this piece.


"Old" vs new OEM PCV valve.


Here you can see the Honda valve.



Thanks.

Probably drilled out the valve inside because it stopped working before and there are ppl that just "cant" spend $4 on a pcv because they need to get drunk later and thats their beer money. It will not be detrimental though but definitely replace it.

 

Definitely not drilled. It doesn't look like the valve was been pried out, but that doesn't mean it wasn't

Sometimes when a pcv is clogged it'll make the engine do some funny stuff. For the crankcase to ventilate the intake manifold sucks unburned fuel vapors. My guess is the engine used to run rich ALOT which made the pcv clog more often.

 

Iv seen plenty of different fittings in my life and you can buy one just like that. And that's probably what they did or like m90 said they drilled it out. They probably didn't feel like cleaning it because it is in an awkward place. I cut my hand everytime

 

If you own a VX, there was a rumour - fairly widely repeated but since discredited, AFAIK - that the original PCV from the factory back in 92-95 did not have any internal moving parts.

Replacement updated Honda parts were apparently "wrong" because these now had the moving internal parts. So, the conventional wisdom was then that these internal parts should be removed and the PCV should be installed like you see in your pics. The PO of your car probably did this.

Unless, of course, that IS the original PCV that has never been replaced, in which case I guess the rumours were true. I've never really found any concrete confirmation one way or the other.

Side story: Mechanics would usually wind up replacing these PCVs because the way to test them to see if they're good is to shake them to hear if they make a noise. Noise = good. Naturally, since the original VX one didn't have any internal parts that moved (or, like I said, maybe they did, I don't really know), they were replaced, but the replacement part number was wrong, purportedly, maybe, who knows really.

 

It could be the original. I do have a VX. I have no idea what maintenance the two previous owners did/didn't do. I held on to the PCnoV just in case. I'll run with the new OEM one and see what changes. Other than a VERY small amount of oil the "valve" and the hose to the intake manifold were clean.
