Replace oem PCV with krankvent?
Hi everyone. This is my first post here as you can see.
I recently bought a 1998 JDM spec-R and the pcv needs replacing. The local Honda dealer doesn't have any in stock at the moment.
I have a krankvent valve (ET Performance) available ( I bought it for my bike), so I was wondering if I could remove the oem pcv and put the krankvent in its place instead. I know how to install it properly, and will retain the rest of the oem setup.
Is this a good idea?
Thanks!

As long as the check inside the valve works it should be fine until you get a new pcv..just be carefull the check seats in the right way or your crankcase will pressure up a bit and probably push some oil past the rings
Thanks for the replies guys.
The krankvent I have is the "universal" one which can be used in any vehicle with approximately 3/8" breather hoses I suppose...
In theory it should be ok, the only concern I have is that it is very sensitive in its operation. I mean, it responds very quickly to changes in vacuum. I played with it a lot of times
Is this quick response a good thing or a bad one?
The oem pcv is spring loaded so it operates a tad slower than the krankvent. In theory, I guess the spring should provide some sort of negligible resistance before some pre-determined (by Honda) amount of vacuum starts to open it.
Now, this should not be a problem at idle or part throttle because the vacuum in the intake manifold is big enough to hold open any pcv, oem or aftermarket.
Could this be a problem at WOT when the vacuum in the IM is not too much? Is the oem pcv spring rated in a way that it holds the valve closed when only a little vacuum is present in the IM?
If the oem pcv never closes then why is it there? I mean a spring-loaded one-way valve would not be there if it's open all the time anyway... WHEN does the engine need the pcv to be closed??
I hope my question makes sense...
