yup.. that's bad..

can u show a pic of where u put that OCT?

and i think ur exhaust doesn't blow white smoke because ur piston ring is ok.. it's just ur engine head that's problem..

u got lot of oil on ur air filter or throttle body b4 u put this OCT?

Hi D7zul,

Sorry for the late reply. Was on a sick leave.

Here's the pictures. The color coded ones are Blue(1) - PCV to Blue(2) Inlet OCT to Yellow(3) Outlet OCT to Yellow(4) Inlet Intake Manifold.

Yeah, I think previously intake manifold was oily black. I haven't check since I put in the OCT. Probably need to get two 3bond engine cleaner soon. Besides lesser engine oil and the need to top it up, what are things that I need to be wary of?

Let me know of your thoughts.

Thanks.

the Blue(1) doesn't have any kind of valve at the hole?

my 20v silvertop got a valve there & it only open when the engine head got high pressure..

i think this valve prevent ur oil to get out of d engine..

what engine is that? sorry, i didn't recognize it

Hi bro zul. Actually what I have discovered are differ from yours.
PCV valve will always open when there is vacuum from intake manifold, not open only if got high pressure.

I've confirm this, when I unplug PCV valve from cam cover (with vacuum hose attached and engine running) I can heard whistling sound came from PCV valve. Which mean PCV valve operate without any pressure.

Please correct if I'm wrong

I don't know exactly how it works. Mayb its a 1way valve

Anyhow, i think caarzee should check that valve 1st. Mayb its not working

hi D7zul,

Here's the layout and the sample image of the PCV. It has a valve but I don't know if it operates when there is high pressure inside the crankcase or whenever there's a vacuum pull from the intake manifold or both. Engine is Nissan QR20DE for 2.0cc or QR25DE for 2.5cc. Car models - XTrail and Sentra year 2004-2007.

Here are some self test, provided the valve is on the hose.

the difference is only the design.. nothing else

I got a friend which DIY and put a stainless steel bottle which they always use for bicycle drinking bottle make 2 hole one for engine piping goes in and for for return back to engine. At the top ofDdrinking bottle he put a mini airfilter for breathing. All the used oil will goes into the bottle and extra air goes back to the engine. No idea if this will increase the hp or hurt the engine or not. Sifu give some clues

It will do nothing except catch the oil vapour. No increase anything and no hurt anything

Bro Izso, the pic showing your myvi oil catch tanks seems not right...the inlet should be the bottom and the outlet should be top. There's an arrow on top that indicates the flow direction. Doesn't really do any harm I suppose...just wana highlight. Awesome DIY btw. Thumbs up
