What pcv valve brand/part number are you guys using on your catch cans? Ive got a 12.1 to 1 compression b20vtec. The catch can im using is a moroso catch can. I modified it so that it has 2 inlets from the back of the block into my can. Now, ive been using a fram fv294 or purolator pv140 or deutsch pcv214. But ive found that my catch can has always filled up pretty quick. Im thinking that possibly my pcv is too weak. Any suggestions or thoughts on this??

Ive got it mounted on the fire wall, about an inch from hitting the hood. My lines coming from the back of the block, go just about straight up, and go up thru the intake manifold runners, then over to my catch can. So im pretty sure ive got it all hooked up as efficient as possible. oh yeah, the can is straight up and down too. so thats not it.

How often do you guys empty yours?

Thanks for any and all help!!

dunno man, maybe it is sucking more than the oil vapours...

how full is your oil level?

t..

ps. PCV valve is only to stop vacuum leakage (i think!)

 

I had the same problem. When I was driving uphill, the can was filling up rapidly!
It was sucking oil all the time.
Now I don’t use the endyn system anymore.
I made a bigger catchcan and connected it to the valve cover. I made a much bigger tube on the valve cover to make the block breath better.

I will make some pictures so you can see for yourself. This method is used in race engines and is working very wel!

I was looking at the endyn system for my B20, but want to hear/see some viable alternatives

 

doesnt the endyn modified setup just drain back into the crankcase? i believe it does so the oil would just drain back into the crankcase, so why would you have a problem with it filling up quick.

 

well, im running the same setup that endyn now sells, but i pieced it together myself. I am not currently running a drain for it to feed back into the crankcase. I tried this last nite, and i found that within 1.5miles of normal driving, i had a full catchcan, and i was blowing some major smoke, had to unhook the can to get back home. I teed the drain from the bottom into one of the 1/2" feed lines like endyn does, from what i understand. Maybe i hooked it into the wrong place? Does anyone know why it filled up much quicker this way? THat is the only thing that i changed for it to start filling up even quicker. thanks

gaskleppie please post some pics and more info on your system.

I have the same setup and tried using endyns recomended pcv valve, no luck it would fill the can in 100 miles now I just use the filter that came with the can screw pcv

again, i am going to say this. i just bought the endyn setup and judging from the pics and instructions it should drain back into the crankcase. the pcv must be lower than the intake manifold and the bottom of the cans drains back into the crankcase.

 

First off, my oil level is normal. Right around 4.2 quarts.

Big B, how often does your catch can fill up with that filter that you are running? Do you have 2 inlets into your can from the back of the block? Does yours drain back into the crank case, or do you have to empty it? What pcv exactly does endyn recommend?

Gsr98vtec, So you are thinking that i just had my pcv mounted up to high for it to drain back into the crankcase(maybe thats why mine filled up within like 2 miles after trying it endyns way)? Where/what height does endyn specify to mount the pcv/can? Also, from the bottom of the can, how does it get back into the crankcase, what does it splice into and where?

What exactly is the purpose of the pcv system? Are there any drawbacks besides emissions by running the filter instead of the pcv that you guys can think of? Will using the filter hurt the cans abilty to catch the oil?

ok, when i get on my lunch break i am going to post a diagram from endyn how this thing works. look for it later today.

 

The top inlet on the can goes to the left nipple on the block. The lower inlet on the can is connected to the drain(90deg through fitting on bottom of can) via a tee and the other side to the nipple on the right side of the block. The base of the can has to be higher than the right nipple in order for it to drain back.

 

where is the intake mani in this equation. i mean, where do you get the vaccum to open and close the pcv?

 

You connect the pcv on top of the can to the intake manifold.

 

well, thats exactly how i had mine setup, as far as routing the hoses correctly. The base of the can was about 3 inches higher than the right nipple too. But mine filled up in less than 2 miles, and sucked oil straight into the intake manifold.

here are a few questions for ya:

1. What size line is used for the return from the bottom of the can?

2. What model/make pcv valve is recomended with this setup?

3. Where does the pcv have to be height wise relative to the intake manifold?

Can anyone think of any reasons why mine filled up so quickly?

I used 1/2" fuel line for the return.

I used a fram fv294 pcv valve.

I had the pcv vavle mounted about an inch from hitting the hood on the firewall.

This problem may stem from using the wrong PCV valve.
I don't catch thatt much oil in mine, but it doesn't drain back into the block (yet).

You have to hollow out the PCV that is in the original location (so it does not function), then install a replacement PCV on top of the Moroso catch can, run a tube form here into the Intake manifold plenum.

Five star:

 

WOTTEG: thanks for the compliments, much appreciated. Girl is hot isnt she.

next up, here is the pic i am talking about. guys i have this installed on my car and it works perfectly. i have no problems with it draining and it does catch oil because my intake manifold is spotless on the inside. actually it looks brand new. here are some pics so you get the right idea.

Who sells this? Where can I find one?

 

This is the PCV that Mike K. said to use Its an Acur # but you can order it from any Honda dealer 17130-pm6-g01

I also run the Endyn kit and It works great.

 

thanks man!

 

Empty less than 1 cup every oil change.

 

you mean there is less than 1 cup of oil built up in your catch can every 3k-5k mi?
so you dont have it setup to drain back into the block?
