pcv valve..humm hope this is the right forum

[digitaldrifter91]

oki i just bought a pcv valve from honda and it costed me 21 bucks....frams is 2 dollars...but its a little bigger...is there any differnce..?? i havent changed it sine i got the car and i think 12 years actaully 13 years and 155k is really pushing it. i have a helms book and they told me that if the ocv valve is making a ticking sound when you shake it it is still good...are they right, mine is making that ticking sound so i shouldnt change it??? the honda one i bought is the exact same one that i have in my car, but the fram looks a little bit bigger, but wayyy cheaper..

click here

it is number 002 on that page...this is a pic of the breather tube areas around that area..

i appreciate it..=)

edit:fixed long URL line to a short clickable one

I made some comments in this thread that might be relevant. I've read that aftermarket valves may not fit properly and can lead to oil leakage, and if you can see that the Fram is larger, I'd be worried about it.

If yours is clicking, it's probably working fine, but I could believe that there's some sludge in there after that many miles, and maybe it doesn't flow as well as it should.

A PCV valve is just a one way valve that opens when vacuum dictates, if you can hear it "clicking" when you shake it, that means it is NOT all gummed up....means it IS working.
Years ago oil vaporized alot more than it does now and they got gummed up routinely,(often it was dry-baked on oil) they were cheap and were routinely replaced. Usually you can just spray carb cleaner in them, shake a little, let the greasy residue run out, dry and replace...check the rubber grommet that the valve plugs into/make sure it seals well around the valve
Newer oils these days at least do keep the PCV system cleaner than older oils did...

Digital, It looks like the PCV system has long tubes. If they're easy to remove, I would take them off and clean them. Also make sure you don't have any vacuum leaks in the tubing or connections. The TB/intake uses metered air from the PCV, and a vacuum leak in the system will cause poor performance.

Since you've already bought the Honda PCV valve, might as well use it. You're assured it's the same as what was on it, and who knows, maybe it'll go another 155K.....

humm so i can clean the older one hu....well i havent opend my new one so i can return it if i want to. soemtiems when i shake the valve on my car i dont hear nothing..then i have to shake it very hard to actually hear something...seems like there is just oil inside...

even if i change my pcv valve, should i clean the pipe that goes to my throttle body/fuel injection area?? what about the breather tube on the side of the crankcase...should i clean that out as well? (#004 on link)

hehe questin is...change or clean...wont it be the same...ill check for leaks though, i doubt there is any...i get good gas milage 275-330 per tank.

i looked at my pcv valve again. hehe i was thinking since it clicking then its fine...well i guess there is a spring behind a plate inside of it and inside the one i have on my car its broken...the thing thats clicking is the spring hitting the valve on the end of the valve...the plate that is on top of the spring is broken off and is just banging around inside...i hope no parts got into my fuel injection or manafolds or something...hehe worse..my oil. im looking at the new one and i cant see what i saw on my older one. so i guess its damaged and i must replace it...well what damages u think occured with the valve OPEN at all times??

I don't think any damage has occurred, Digital. However, you should have a much better idle quality and throttle response with the new PCV valve.

humm i have been getting abnormal idles...i would adjust it and then later on it would just go back down....should i clean out the lines after the pcv valve?? can i use brake cleaner or carb cleaner? how about the other tube on the other side of the crankcase that goes back near where the throttle body is...should i clean that out to?

btw thanks for replying

Yeah, I'd clean out everything that is easy to get to, with either the brake cleaner or the carb cleaner. Both are good, although the carb cleaner is better for dissolving carbon. If the idle still isn't good with the new PCV, try cleaning the throttle body. You only need to clean it in the area where the butterfly meets the housing. If this dosen't help, then clean the IAC.

Take the steps one at a time, so you know which one it was that improved the poor idle. Good luck.

hey i just changed my pcv valve...i looked inside the tube that geos to my throttle body area and it was clean...the new oen made my engine really quiet andmy idle is not as low ne more. throttle response is better as well....i have yet to clean out the other lines like the breather line that goes on the crankcase and the throttle body..yet i checked the throttle body and its clean as a whistle...humm i will just do it any ways...ne thing else ishould do...thanks
