I'm confused - how can you run multiple cc's on the pcv system?

I have a second on my breather before the filter so the filter doesn't accumulate too much oil, but that is a crankcase vent, not the pcv system,right?

 

Not multiple OCCs on the PCV. But one on the Intake side one on the PCV side.

 

Gotcha' - I thought I was nuts or something. The crankcase vent side can is more to keep the filter clean than anything, though, I rarely empty that one. But the pcv side on mine - just like everyone elses, Orochi, is emptied weekly. There is definitely a lot of oil going through there.

 

His car is the miraculous SRT-4 which doesn't have oil flying every which way in his engine! [>:] Ha ha RIGHT. Thats fine though, if he doesnt want one its all good, not my car. I want one on my car, just because it does a good job at what its supposed to do.

 

well im just curious why everyone is so worried about it. every other turbo car on the planet runs the pcv line to the intake and has a little oil like the srt-4 but no one seems to worry. like i said the 5 pervious cars i had i never ran one and it never bothered me. and beside that little bit of oil in the intercooler wont even make a noticeable differance,honestly do you feel any performace gains or does your car run better with it? is there prof that it is better for your engine? none that ive seen and its always been my understading that you want positive vacum on the pcv for better ring seal. have i been lied to all these years? why does every other car on the planet run there pcv line into the intake track and not have a problem? turbo or non turbo they all do it. why dont i see occ on n/a cars? a little oil in the lines is normal from what i understand. i think the occ is more just to put your mind at ease. i always thought occ where for long enduance track runs where there is constent on/off wot driving for hours on end. people put them on and look after a week or two and see a few cap fulls of oil and are like LOOK its working! but if they didnt have it then it would have just been rerouted into the intake track and like roadrunner said burned up. so i dont think you ever have enough oil in your lines to ever notice a differance. you might have a consent ounce or whatnot in there but like i said not enough to hinder performace or reliability. maybe im wroung on this tho the occ is in no way a bad thing at all but i do think it is WAY over rated. thats all i am saying.

 

Now, obviously a couple of interjections I made are the ones in green.

It seems like you base what you say on a modicum of automotive knowledge. With that knowledge, you should know that there are often better ways of doing things. There is much room for improvement on any engine; we don't have budgets to keep like the engineers designing them. I would assume that a cc would be used if cost weren't an issue, but is it most certainly is an issue when you have to create 150,000 engines on a budget(or even 15,000 like in the case of the srt-4).

The fact that oil is prevented from entering the intake manifold, and after-the combustion chamber, says that there will be some fouling over time as a result of its presence. Ever look at old valves or injectors that are coated in crud? That is generally from contamination and the contamination is generally carbon deposits or caked oil acquired in the combustion process. A product that stops some of this can't have anything but a good result over time.

Maybe you should consider it - who knows, your 125,000mile cars might become 200,000 mile cars.
Besides this is inexpensive(like 25$) to do, and it looks fine in the engine bay.

As an added note - the cans aren't used exclusively for long endurance runs or on turbo cars only. A large # of BMW's on the BMWCCA circuit run them for 5 minute to hour long races. Many Porsches I have been in, on the circuit, have them as well.

I think more to the point - It should be used where wot is frequently used - and for me (and most srt-4 driivers) that's a lot.

Please don't think I am attacking your stance - you are entitled, but you might consider what we are saying here. Whether or not you use one is your choice.

 

im not says its a bad mod to do at all but im just saying that people make way to big a deal of it like its something you have to do when its not. nice yes but not at all necessary for the life of you motor. i plan on running one eventually but you get people like the person who started the post all worked up over something thats not as important as it seems. i was just letting him know that he will be ok even if he holds off. sure after time tho it could foul out your plugs faster ,cause some varinshing of the valves but if you run some marvel or other simular type products and change your spark plugs regularly then youll be fine. all im saying is yes it is a good thing to do and it does help to a degree. but its not a essential thing you need for the life of your engine as some people tend to think. the stock set up doesnt even connect to the intake track anyways only after people put the aftermarket intakes on they connect the line to the intake. thats why i dont get the hype. but post your right i do have a moderate amount of knowlage im by no means a expert on these or any other car i just know from experiance and what ive seen and done in the past. only time will tell on these cars and i havent seen anyone over 80k yet who knows? everyone will just have to wait it out.

 

Theres a few SRT-4s over 80k, some near/at/over 100k also. Just an FYI.

 

holy crap who put 100k on there car? hows it run?

 

Thank you for acknowledging the validity of the product. I agree that it isn't necessary, but I personally feel that it is good. Just as you didn't want people to think that it is absolutely necessary, we just don't want those less knowledgable to think it does nothing.

I highlighted one thing for you. You might be misunderstanding what we are talking about. It is true that the breather on the drivers side of the crankcase only connects to an aftermarket intake. But - the PCV valve is located on the passenger side at the back, and it is routed directly into the intake manifold. This is the one we are saying is important. Check it out some time, I promise you will find that more oil is getting through there than you think. Some of it flows back down into the intercooler through the throttle body, then down the cold side pipe; the rest goes into your engine.



BTW, lilsparkplug, who has 100K - that's very impressive. I want to hear there opinions about our car after that many miles. (and I can't get used to your new name)
