I was board today, so I decided to make a DIY oil catch can. I think it turned out pretty good.

Parts:
Colman Fuel Tank (wal-mart): $8.00
Fram PCV valve (wall-mart): $2.50
3/8" hose barb (Home Depot): $1.55
10' hose (Home Depot): $3.50
steel wool (Home Depot): $3.00
4" hose clamp (Napa): $1.50


Cut loop off off top, then bored a hole in the top (with dremel tool) for the PCV valve.


JB welded PCV valve into bored out hole, then JB welded a 2-3" peice of hose to the botom of the PCV valve.


Bored hole (with dremel tool) in side of tank to accept the 3/8" hose barb fitting.


JB welded barb fitting into side of tank.


Filled tank with steel wool, then screwed top onto tank.


Mounted tank on right shock tower, then ran a hose from the PCV valve to the intake manifold, then another hose form the hose barb fitting to valve cover.


Finished product.



What do you guys think?

 

hmm a++

 

Any functional DIY parts are cool. You get a

Thanks...this setup is only tempory...the main reason I made it was because I was board today, and sick of my fuel rail always being oilly from the APC breather I had on for the last 9 months(since I put that mtor in)...hehe

I will be using a Endyn dual chamber setup on my new motor.

It's a good way to keep the air chamber from getting all greezy. The tank is rather large though. Looks like a mini fire extinguisher.

 

yeah definitely any DIY parts that works gets A++

lol yeah it kinda reminds me of a small fire extinguisher, still cool though

haha, yeah it is rather large...at least I won't have to worry about it filling up every other week though...I was going to put a valve on the bottom of it to empty it, but I forgot to look for one when I was at Home Depot.

 

wow, looks pretty dam good, u should paint it though, gives it a nicer look

 

i would take out the pcv valve and just have the pipe.. since there is no pcv there to begin with.

other than that.. looks good. now make one for the real pcv system

That is actually the only PCV on my motor...its a JDM b20b, and stock the PCV valve goes stright to the valvecover. There is alos no "black box" on the back of my motor.

 

very creative

 

nice job......
got some of my creative gears turning

 

Damn nice job.

 

very good. and color matched to boot!

 

you do realize that steal wool comes apart very easy and you now probably have small pieces of it running through your motor

Can anyone back this up? I put a bit of research into catch cans before I put it together...90% of the stuff I read mentioned putting steel wool into it.

 

on me..

kinda hard to notice it's b20ness.

 

very clean dude.

I understand...I figured it would come up...

its even hared to figure out that its a B20 in person...there is so much dirt, sinders, gress, etc. on the front of the motor that you can not see the engine code at all...

 

I agree. I would use the plastic type Steel wool that has less of chance of breaking up. But other than that you still should be fine..

 

looks good, but you should have another breather on the valve cover somewhere. also maybe cut an inch off the in tank pcv tube. i can fill the can on my b20/vtec in about a week, but i vented the block in the regular b block locations.

i was planning to switch my pcv to valve cover like that and have the vented block run into a high mounted can with an open breather, figuring the baffled valve cover was good for something. but from what you sat i guess i'll also still need to run a catch can too.

 

Looks good. BUT..

Why is it rigged up to pull vapor from the valve cover? That's not good.

Why didn't you drill a hole in the back of the block and put a nipple on it so you can pull crankcase vapors?

 

Go back to Home Depot, and buy the ball chain that is used on basement lights. You know the chain that hangs from the light fixture on the ceiling in your basement. They sell it by the foot, and it won't come apart like th steel wool, which could also rust. I dropped about 15' of the stuff into my home made oil seperator tank, and that baby worked fantastic. If I beat on the car, I could fill the tank in 1 afternoon, but if I drove sanely, and babied the car, I could go a month without the tank being full. LS/Vtec, seeing 9,000 rpm.

 

nice ******* job!! BTW what intake manifold and TB are you using ? if you dont mind me asking =P
thanx

funny you should ask that...its a 1st gen b16 intake manifold, and a 94 LS throttle body. That throttle body isn't really meant to go onto that intake manifold too well...it took a good amount of modification to make it work. It worked fine though un until about a month ago when my idle started rising. Some days it idles at around 2000, but never below 1400...it kind of pisses me off cause I cant find a vacuum lean ANYWHERE!!!
