PCV Valve: clean or replace?

[Dober89]

Why do people say to replace it with an OEM unit? I just went and got a FRAM one because I didnt feel like ordering one from a dealership in the USA. Its just a simple piece of plastic how could OEM be any better than aftermarket?

Also mine was original when I replaced it, one day I checked it and it wasnt rattling so I went and bought one and when I pulled the old one out it had started moving again. Couldnt be bothered to return the 7 dollar part though so I just installed the new one anyways.

I think the older rodeos use the elbow type.

yea, yours is a little different from ours. The newest model Rodeo had a different valve. Better I think. That year didn't have the oil burning issue like the 98 -???

My original must have been broken. I got a new Purolator PCV valve from Advance for less than $4. It clearly blocks reverse flow. It was a 10 second changeout, and the grommet is intact! I can't imagine that anything is going to change with the new one...

[rod2004]

I think it makes a big difference with the new one.

Save yourself from a blown gasket and oil consumption.

If there was air flow both ways, I can't see blowing seals out. My Rodeo consumes very little oil. I just added about 1/4 qt. between the last changes. I'm curious to see what happens, though. I think it would make a difference is an engine which doesn't see otherwise good maintenance.

Maybe the 98+ Rodeo's are using a different PCV valve, I don't know, but I used a fram one for about 500 miles before I could tell that it didn't have a good seal - in fact, it popped out very easily on my '97 Rodeo.

I never changed my original one until about 2.5yrs ago - probably didn't need changing, but did it anyway, honestly never thought of it prior to that.

My truck has never used more then 1/8 qt of oil as the norm, with hauling a heavy boat the most I ever had to add was 1/4qt in 3k miles - but this engine has been superbly maintained with all new filters once every year, sometimes the air filter will get changed twice in one year, or twice in 6 mnths even, depends on how dusty the roads get that we travel on.

The pcv valve nor the EGR valve ever crossed my mind till I came to this board, in which, changing out the PCV and cleaning the EGR are very standard requirements, primarily for the 98+ engines, but felt mine, then at 7yrs of age, could use it too.

These are primarily the sources to clean if you have oil burning issues - I just always figured, after coming here, that by keeping them extra clean will prevent oil burning issues in the future.

I am VERY determined to see just how far I can get this Isuzu engine to go - as long as other drivers will understand my goal and keep their bearings (vehicles) away from mine

Rod2004 - Curious, what's with the head-banging symbal on the Aisian 4-spd auto versus wishing you had purchased the 5-spd manual??

Is that auto tranny a nightmare to service, like our 4L30-E's or what??

[rod2004]

hehehe

The head banging is because I wish it has a filler plug instead of the dipstick. It's gona be a pain to drop the pan down.

And I rather drive a 5-spd cuz auto sucks.

Did I just hear an argument FOR the 4L-30E?!

I believe we just did, Surfer !

That's the 1st!

Rod2004 - is it possible, when you drop the pan, to put in a drain bolt for future drain/refills?

5-spds are fun; driving one this week - giving my Mom's car a work-out this week since it hasn't been/and doesn't get driven enough. Much different going from a high-stance SUV to a 2-door sit-way-down low some-what sports car.

Have it worked out that I could drive the car at least 2-3 days a week, allowing at least 200 less miles on the Rodeo a week - as long as too many tools are not needed at work.

I could just see the back of this car dragging and the entertainment provided to on-lookers when they see an 11' ladder on the top of a tiny car opcorn:

But, spares the Rodeo from the city type driving that we seem to be doing a lot of this year. And, after driving this 5-spd for 4 days now, I'm quickly reminded just how many shifts an auto goes through.

Though I have to say, I HATE holding that clutch in during heavy traffic, specially when other drivers have forgotten that people DO still drive stick-shifts!

Its real easy to get a small funnel and pour the trans. fluid down the dip-stick tube. Andie

[rod2004]

just replaced my pcv valve today. felt good.

yeah Andie is right. It's real simple to pour the trans fluid into the dipstick tube.

[rod2004]

I've also been thinking . . .

if you put it in PARK and let the fluid flow out the cooler line without pouring in fluid at the same rate, would your Trans get crapped out?

I don't mean to leave it running until it's all dried. Say, if you stop every 2-4 gallons and refill and then start again . . .

I haven't done it but just curious . . .

I don't know Rod, I've honestly never had the guts to try.
