Thread that combines all my car threads

[mk3pete]

the exhaust is in i just havent got a photo will post up soon though

its just a catch can from super cheap
connected with a fire hose lol
i couldnt find anything else at home, i do need to fix this hehe

[mk3pete]

i did some modifying to my catchcan after reading on from this link

http://forums.vwvortex.com/zerothread?id=1940008

heres my abomination i slapped together at home from lots of different things
i bought the can from supercheap

gunk left inside after emptying it

nice and clean

here is the top, it already had 3/8 bspt (tapered thread)threads
although i had to tap it out more with a 3/8 bsp (parallel thread)tap so i could screw a double ended fitting through it
purpose of this was so i didnt have to weld anything

this is the top finished, i joined the hose to the top i screwed in using standard pneumatic fittings
thus extending the inlet to the bottom of the can
for the breather i used an exhaust silencer commonly found on pneumatic machinery

the can with the stainless steel wool inside acting as a filter

finished


in the car hiding next to the intake
i used 3/4 inch steam hose its the only stuff i could find that fitted the hose barb on the car

Forgive me for the n00bity of this question, but which oil catch did you replace?

[mk3pete]

i didnt replace it i modified it the first pic you see is the one i put in about a year ago when my pcv valve broke i didnt post anything about it back then

[peedman]

nice work but im not sure u would really want to put steel wool in there. i know it might be a long shot but you wouldnt want any fibres to be sucked into the motor if u know what i mean. its also gonna lower the capacity to store oil so u have to change it more often. just a thought.

[mk3pete]

i cant say that it would ever enter the engine it wouldn't be possible
the reason iv done it so it lowers the fumes,
before it didn't smell too good
i hardly ever emptied it anyway i think it took 3 months and it only filled about a quarter

I like that idea of extending the screw thread so you can put on a hose fitting on the inside. As for the steel wool, I hear a lot of people do that to act as an oil/air separator, i.e. trapping as much oil vapour as possible. Didn't think about stray metal being sucked up though - there is a chance seeing as the airflow is moving from the catch can towards the intake. Maybe a small baffle (like the ones you see in the more expensive oil funnels you can buy) could be used to fit over the hose that leads to the intake?

[mk3pete]

i cant see how the air flows from the catch can to the intake isnt it opposite
i mean the waste comes from the rocker cover into the catch can

[rayray086]

Yeah that's correct, but what comes in must come out too right? It might be a very slim chance that any piece of metal would get sucked up since the output hose travels from the catch can back to the intake.

Another way to think about it is that the pressure from the crankcase/rocker cover is usually higher than inside the intake tube. We know that anything from a high pressure/density will want to move to a place of lower density, and that's where we get the air/oil flow from the engine to the intake (with the catch can in between).

Wait, is your output from the catch can routed back to the intake or just filtered out into the atmosphere?

[mk3pete]

its just filtered to the atmosphere hence the reason why i put the ss wool in plus the exhaust silencer filter

[rayray086]

Ahh fair enough then! Solves that issue!

[mk3pete]

indeed i thought there might be some sort of vacuum affect something oh well.

[mk3pete]

i washed my car today thought id take some pics
they aren't the best but hey its from my phone
