oh yeah got a new rubber seal as well. the old one was full hard and had dried up oil and stuff! looked shocking.
also i didn't change the rubber tube...
what can i use to clean it?
Yeah a Catch can is easy,I got one.I had it in for a year,took it out cause I thought it was hardly catching anything but a couple of months later I put it in again cause it definately catches some oil.I plan on tracking my car soon so I know it will definately be catching oil on the track.Not a necessity but I would rather the blow back oil go into the catchcan than the Intake Manifold.
To hook it up,you use what the PCV hose is connected to at both ends.So one hose runs from the PCV end to the catchcan and the other hose from the Intake Manifold to the catch can.
but i'm wondering how does oil go up to the pcv valve?
does it only happens at high rpm?
what if you drove your car under 3000rpm for a while..could you say your catch can will be close to empty?
so you are saying drive using the bottom half of the rpm range and you will get very little oil going up the pcv valve...stay in the top half rpm range often and your oil catch can will fill up fast?
i did some testing today..
stayed under 3000/3500rpm all the way to work...and same all the way home. 40km total.
from what i could see i didn't leave any blue smoke at all today like i did every other day last week...
i'm gonna do this for a little and see what happens with my oil level
><
No the catch can will catch very little.I've heard in my d-series after a track session you might catch 10-15mm at most.
It's hardly even worth checking for street driving,a little bit might go in there but it's oil so it just sticks to the inside of the catchcan and hoses,it wouldn't even fill up at all on the bottom.
I drive my d-series to redline 6,500rpm all the time and just a dirty catchcan but no oil on the bottom as such.Most people take them out after a year cause they would raher the engine space or it's not doing anything.It does stop that crap from going in your intake manifold but big deal really.I'm just a clean person.The only reason I put it back was cause I'm gonna track it.
hmm
i've read from people that h22as can suck up oil through the pcv valve after hard driving...which after a while will leak oil into the IM and then you will puff a cloud of blue smoke...
but a good pcv valve is meant to reduce oil consumption.?
so i don't get it..
is this just how the h22a engine is?
i don't blow a cloud of blue smoke when starting my car...so does that mean my valve stem seals are okay?
if they are fine how so how exactly am i loosing oil could it have been the pcv valve the past few months?
it has only been 2 days since i got my new pcv valve so i gotta see how i go in the next 1000km.
cheers for your replies again.
BUT...i did puff out blue smoke twice with the new pcv valve...is some oil still stuck in intake manifold or something? i dunno
i will need to do more driving first then see where my oil level is at...
meh i'm really thinking of installing an oil catch can...how hard is it to do lol
anyone have one and can comment on how many ml it catches? like 100 or 200ml of oil every 1000km...?
I have DIY oil catch can with steel wool inside to catch oil fume. It catched about 3 oil's bottle caps of oils after 1 year. I'm daily driver. My car didn't blow any blue smoke before and after install catch can. I didn't need to top up any oils between every 6 months (10,000 Kms) services.
