Pcv valve install in my honda valve cover

[David wulf]

Yes thats what i did . I have the champion rockers and needed the tall cover , well Tim was out of stock when i got my cam and rockers . So instead of waiting for them to come in or buying the costly spacer , i went with plan B . Which is pull out the guts of the cover then you have enough room for the rockers , but still need the valving that was removed . Bought a 1.99 pcv valve the smallest i could find , couldn't put in the stock hole cause it will hit the rocker . So drilled a hole on the front top center and it fits right between the rockers .

Am I missing something? Doesn't the valve cover breather allow pressure to come in, and out? The PCV is going to restrict it to go one way only.. Or am I missing something? :shrug:

PCV= positive crankcase ventilation.

Crankcase pressure is pulled via a vacuum source.

Well maybe i'am missing something , what i took out was a flap type valve what i thought is the same as a pcv valve . PCV valve are used to vent 4,6,8 cylinder motors this is just 1 . If i have F 'ed up it can be pulled and changed , hopefully will get some more advice from others .

Yep got it now , so unless i run a hose from there to maybe my fitting in the intake it not going to be sucked open right . So i guess just a fitting to a breath filter ?

That's correct

That's correct

Thank you very much :thumbsup:

I'll add I do not think you need an actual PVC valve. Most guys use a barbed nipple and a catch can. However I don't think your method is a bad idea either.

Crankcase pressure will push the PCV open. It is a very light spring that keeps it closed.

After thinking about this, it may build up some pressure in the crankcase as the orifice in the PCV is small. I say run it, but if the crank seals start weeping oil, you need to ditch the PCV valve.

David is right,the stock valve does the same thing.now he has the room he needs and can out it where he wants it.

This is what i have found out while working the bugs out of getting the motor running . At high RPM'S the motor will open the PCV valve , right now the valve is in the cover with no hose . And from a very high idle to big blips of the throttle it spits oil on my plug wire , and this is without any suction from the intake like should be there . So i think my little trick might work , i can still plumb it to the intake and maybe go though a filter or not .

Sounds like you will need a puke tank since there is no baffle to keep the oil from the PCV.
