I make a cheap catch can out of parts from harbor freight for my 97gt! My Catch Can Review- • Its the Simple Things.... Link to Air water separator-amzn.to/2PMXRXF
Nice new opener man! So I did this same thing a few years back as I too wanted to save some money. I think you are going to find as I did, that it just really does not work well. You can try to add some like scour pad in there for a media to catch the oil and keep it from sucking back out, but the design isnt really adequate for this. The oil for the most part will just flow right through it. Also, great points on the drain nipple because again, most people do not talk about it or address it. I had one with a valve and capped the tip and it still leaked from time to time. I think the design you got is a little better in that regard. Overall great video man. Just work on fixing that cropping man!
Yea.. i figured it was worth a try.. if i catch a spoon full..thats still a spoon full that didnt go into the engine.. we shall see tho. The cropping i dont have a clue on..but i got a lot to work on. On my phone it doesnt look cropped tho..i also gotta work on keeping the camera more steady..
Won an ebay auction for a Chinese copy of a ProVent 200, $19 landed. Has the stainless filter, which is reusable (I just spray it out with degreaser every filter change,) and more importantly it runs the blowby gasses through that filter, which removes a whole lot more oil than just letting some drop out. You've made a good DIY system that's better than nothing, but for the cost, I'd say it's more worth it in the long run to spend an extra $20 and get a can with baffled airflow and a proper filter. It doesn't have to be a name brand, cheap copies are fine, just get one that pushes those gasses through a filter.
That's cool catch can. Does your car have excessive blow by? Hence all the oil. On my xterra when I unhook the pcv hose it has noticeable vapor coming out (smoke) and it's using more oil than it should. I want a catch can to catch that oil.
Mine doesn't have excessive..but any bit I can keep out of the intake the better. Mine usually have about 2 table spoons every 3-4 months when i check it
Hi, Do you have any idea how much exactly this catch can increase the pcv pressure because the filter restricts the ventilation and shoud increase the pressure?
Just curious, did you see any problems when you reduced the flow of the PCV to the intake from 3/8" to 1/4"? It would seem that a 50% reduction in the flow would increase the crankcase pressure by adding an increased restriction in the line?
I've done it before on a V8 and it was like hell, the engine wasn't responding quickly and you can hear the engine struggling to breath and you will hear a high vacuum sounds coming from the hoses and the catch can that if the hoses didn't collapsed on you :) So just don't do it try something with the same hose size
@@M91211 Yeah, I kept the 3/8" all around because I suspected that would happen. But I ran into another problem when I put a catch can on the air intake side going to the valve cover. I made the mistake of placing a check valve between the catch can and the breather tube (to stop oil from being drawn back from the can to the intake) and found that the air goes BOTH ways in that tube (duh) so instead I capped the line coming from the breather to the catch can and plugged in an after market filter on the air side of the can. Now the problem is gone. Moral of the story - don't use a check valve on the air intake side.
For 25$ I’ll just buy a real catch can this looks like a headache and way too much work for just a can that catches oil found one on amazon for 25 ... good deal

Built the same thing 12 years ago. I put BB's in the canister.

You could put a mini 1/4 turn ball valve on the bottom.
Yea..i should mount it and do that..but the way i have it in the groove of my valve cover it wouldnt fit.
The line with no oil is your air in the Pcv line is your air out
There is no "air in" its a vacuum.. the pcv has vacuum on it which leads to the intake
Hi,
Do you have any idea how much exactly this catch can increase the pcv pressure because the filter restricts the ventilation and shoud increase the pressure?
This is a blow thru design. There are not check balls sonit doesnt increase pressure.
Just curious, did you see any problems when you reduced the flow of the PCV to the intake from 3/8" to 1/4"? It would seem that a 50% reduction in the flow would increase the crankcase pressure by adding an increased restriction in the line?

I havent had a single issue. Car is still very responsive especially for 23yrs old.. no noises or struggling.

The material for the plastic is not heat resistant ,that could be a problem
Hasnt been an issue so far but i could see it being an issue eventually.
hype thanks dude! 👊👊
Whenever you broke off the EGR valve hello through an engine code
I didn't break off the egr valve. When it was deleted I never got a code because I had the egr disabled with my sct X4.
Don't forget our engine code
Any idea how to install oil catch for 2007 Honda Odyssey?
It would go between the valve cover tube if it has one and the a line that leads from intake tube.
Replace the valve cover
? What? Nothing wrong with the valve cover
@@TheModAddict if it’s eating oil it’s the pcv port into your intake. Pcv is in your valve cover.
You can change pcv without changing valve covers. My pcv was brand new and still getting bleed by the valve at wide open throttle.
@@TheModAddict in my truck you can’t change the pcv. ☹️it’s just a vacuum air port built in.
Did it work?

Thats always a option.. ill eventually get a bigger better one. But for a quick one this one works great. I appreciate you watching.
$6 is too much of an expenditure for that car.
Probably so..lol

I havent noticed anything
Pneumatic lines are 3/8
