JLT PCV Pre-Filter is it worth it?

[bawazir]

What do you guys think? is it worth it to get a JLT PCV Pre-Filter? is about $47
Do any one of you guys installed them? :baaa:

You can make your own for a couple dollars with parts from home depot ;)

[bawazir]

Yes, for all the reasons mentioned.

do u have them on your car?:confused:

[RacerX]

I have them, they work great! Easy to clean with carb cleaner etc. every couple of months. Just pull it off and spray it out. I had to modify it a bit so the hood didn't bend it too much.

don't waste your money man, it's the same thing they use for paint sprayer things.. they are a fraction of the price at hardware stores...

Does anyone have a picture of one on their car?

That's good to know if there's a cheaper fix. You don't remember exactly what it's called? I knew $47 was expensive for what you get, but, I was being lazy and didn't see anything allready made that was similar.

I don't quite remember what they are called on the package, I built mine back in 2006 or so. If you go to the section where they sell the stuff for doing spray paint they should be by where they sell the spray gun parts, they are put inline to keep fluid out of the air that is being delivered to the gun.

[Vortech347]

No, any of those little novelty items don't work worth a crap.

Install a breather tank/catch can. Its the only thing thats worked as it should regarding oil control.

The paint sprayer things are designed for a tiny bit of water mist. Not oil.

bawazir, how about using the search function?? If you did you would have found these pictures and be alot less annoying.

Good thing you're a dick about the money you wasted. :D

Seriously, If you don't want ANY oil going into your intake you need to install breather tank that runs from both valve covers. The little novelty stuff works for about a day. (air compressor filters, these filters)

No disrespect....But the pre-filter, in the pic, is on the wrong side...Drivers side allows air to enter the crank case...

Should be on the Pass. side...this is where the air is sucked from the crank case (oil) and into the intake...thus the oil problem...

Unless the PCV system was reversed...

There's vacuum on both sides. At least on stock without SC. Both should have some sort of pre-filter.

[FordNut]

No there isn't. One side in the OEM NA setup is the inlet (driver side, before throttle body), the other side sees vacuum (passenger side, after throttle body).

Commonly that is reversed on the SC setup.

Not that anything is wrong with posting questions but there is a thing called the search function. I usually am the one sticking up for noobs when someone posts a redundant thread and catches slack for it. The thing is most noobs learn to use the search function after about a week or so, then they will search, and if they still have a question go from there. It's not that you say to use it but how you say it. Apparently though some people don't get it or refuse to use it at all. Look at my post count even though I have been here since 2007 I am only in the 500s. I guess you could still call me a noob with that few posts or can see by my post count that I do my research so I don't ask a bunch of silly/already answered questions.

I learned how to use it so I wouldn't waste peoples time and server storage asking questions that have been answered 100 times over. It's one thing to do it here and there but it is another to do it with every thread you start.

All I was saying is the questions he constantly posts could be easily searched for and then he could develop intelligent questions from there and not bring up old stuff every time he has a question. The amount of time it takes to get half the responses he could have found his answer and moved on or formulated a better question. The one thing most so called performance enthusiasts forget to take into account is the amount of research it takes to do things right and to understand why you need/want to do certain things or combination of things.

These are the same guys who will walk into speed shops and get ripped off because they only know what other people told them. They haven't taken the time to do research and develop an understanding of the subject so they are easy prey to the scam artists. That is why you have some many snake oil items on the market that sell great but don't really work.

I myself generally will understand and retain the knowledge better if I spend some time to do the research, gather my data, and then ask an educated question about what I am still curious/unsure of. Just throwing blind questions out gives you a ton a off answers generally based off other peoples opinions and not fact or experience. This then generally leaves one with less insight than if they had just spent a few minutes educating themselves enough to ask an educated question on the subject.

I could swear I took the hose of the driver's side and could feel suction while the engine was idling... Actually, that's where seafoam got sucked into the intake before the TB.

The one in the photo does NOTHING except filter air going into the crank case....it needs to be on the PCV side if it is to do anything at all!!!:rolleyes:

I still don't see any value in these oil separators and have had ZERO problems with my PCV both N/A and Supercharged without one......209K miles and still doin' fine!!!:beer::bows:

Back to the original question......don't waste your money unless you run at constant high RPM's (as in circle track)!!!:shake:

Sorry about the hijack but my point is the oil separator is not needed for street applications...IMHO!!:shake:

[FordNut]

When the inlet hose is disconnected what you will find is that both sides have suction, but the one that goes to the air filter side of the throttle body has very little vacuum. Put your thumb on it and you will find very little pull. The other side connects to the valve cover, then thru the crankcase, then the other valve cover, then the PCV valve, then to intake manifold vacuum on the back side of the throttle body. Put your thumb on this side and it will develop pretty decent suction.

[RacerX]

Hey Brian! If there's vacuum on both sides, yes, less on the driver's, so as soon as you attach the hose back on the driver's side, it then pulls air out of the intake because of stronger vacuum on the passenger side. Duh! So you can just put a little PCV filter right in the drivers side and plug up the hole in the intake? Used to do that on my SOHC 4.6!

Not wise to disconnect, then you're drawing unmetered air into the intake via the pcv valve. Best to leave it connected, and if you want to use a trap put it between the valve cover and intake manifold on the passenger's side.

What's even worse is when they used that txt lingo via the corporate email. Do folks not know its a correspondence that can be shared and read by all.

Ok back on topic. Ive never seen the need to purchase this. Because I haven't heard a good argument of what value would it serve?

[FordNut]

I've seen the oil puddling in the bottom of intake manifolds before, the theory is that the filter/trap would prevent this. I hope to never find out 'cause that would mean I've pulled the blower off. Which means something broke.

Not fooling myself, someday the engine will be rebuilt again. One thing I want to change is the pistons, they were custom ordered to VT specs. John at MP said if he was getting new pistons he would have ordered them with offset wrist pins so it doesn't have the slight rattle when cold.

Anyway, I do know the trap I'm using makes a difference even if it doesn't stop all of the oil from getting back into the intake manifold. I have a drain valve on mine and I empty it when I change my oil, there is always some nastiness that drains out of it.

You are 100% correct. No it's not the best but you just need to learn to use it the right way. That is why there is an advanced version that lets you search by keyword, user name, select what forum you want to search in etc...

You might occasionally have to dig through a bunch of crap but most time you can find what you are looking for if you select the correct criteria. You will have to dig through even more in the future if we keep getting dumb threads added all the time. Next one will be what does righty tighty, lefty loosie mean.

I am all for human interaction, why else did I drive over 2 hours each way to help Landy install his headers when I had never met him before except through a few posts on this sight. He didn't ask, I volunteered because I like meeting new people and will always give someone else a hand.

You can look back at all my posts and you will see this is the first person I have ever said to use the search function to.

I wish Ive known about this little tidbit of information and spec'ed out! I have piston slap when cold which goes away when the motor reaches operating temperature. Offset wrist pins are offered by Diamond and Manley....I need to check which pistons were installed. I know they were Manley custom spec MMR pistons -11cc for 10.1cr. No wonder Aluminators use the Mahle 4032 alloy...just as quiet as hyper pistons.

I just wish somebody had told me about Modular Performance before I did my first BB/S build, it would have probably been the first and last. At least I found out about them before the third time. John knows his sheet about modular Fords.

Alloy pistons like the Mahle and hypereutectic ones don't expand like forged ones do so they can be installed with a lot tighter clearances to the cylinder walls. But they are generally more brittle and more prone to break ring lands or skirts. Another trade-off. But the offset wrist pin trick seems to be the accepted cure to quieten down the looser forged pistons.

I dont mind the noobs questions, sometimes they bring up stuff I never would have thought of, and therefore would have never searched for. So thats a help, also it gives us something to do do, search. Which sometimes, can lead you across interesting threads.

[Glockafella]

And my opinion on the Prefilter is, if you want it...get it. It probably doesnt hurt. But I have never seen a factory set up a PCV with a pre-filter. When the German car makers start doing it, I will follow suit...well actually I would follow suit if these were a little cheaper! If these were 20 bucks, I would have 2. But $47 for one is a little rich for my blood.

And my opinion on the Prefilter is, if you want it...get it. It probably doesnt hurt. But I have never seen a factory set up a PCV with a pre-filter. When the German car makers start doing it, I will follow suit...well actually I would follow suit if these were a little cheaper! If these were 20 bucks, I would have 2. But $47 for one is a little rich for my blood.

I'd say if you're going to put one on at least make sure it's going to do the job. I doubt that these really do much, as well as the other little air compressor filter bowls that people like to use. I do believe the one I've got works, but it's expensive... around $250

Mine is as quite as a mouse cold/warm/freezing, doesn't matter (other than the usual head/injector noises)

Old thread alert! A couple of observations on this thread:

1) Noobs should search
2) JLT Oil seperator is better than nothing (I have one)
3) FastblackMercs is on the wrong side - unless he has 2 - I'm guessing not
4) Look inside your upper intake and ask yourself why it's brown and oily. See #2
5) If you've never looked (see #4) then you don't know.

Aren't enumerated responses great? :D:D:rolleyes:
I guess I want this: http://www.maesco.com/products/racor/r_extras/r_new/r_new.html (thanks Brian)

Would http://www.maesco.com/products/racor/r_extras/r_new/r_new.html work Ok for NA?

I believe the 4500 is their smallest. It would be tough to fit anything larger on the MM. Look up my PCV thread for some pics.
