Positive Crankcase Ventilation (PCV)

Positive Crankcase Ventilation (PCV)
Kaya pala dumudumi ang throttle body and map sensor kahit na may air filter dahil pala dito sa pcv.. Return line ito para maibalik yung blow-by gasses and dirty oil sa combustion chamber for a cleaner burning engine.

One solution is to install an oil catch can to filter the blow-by gasses of unwanted used oil para pagbalik sa combustion chamber at walang residue na maiiwan.

My question po, is it possible to install an oil catch can and not mess up the operation of the pcv? Thank you.

RE: Positive Crankcase Ventilation (PCV)
unless you're running turbo or direct injected engine, oil catch can will not do much for a Naturally aspirated, Multi port injected engine. Hence, the stock PCV valve will suffice. The only thing you have to watch out for is your PCV getting stuck up (may take 5years or more for a new car). The 3A92 mirage engine is a smart engine in itself, It doesnt even have an EGR system to maintain!

^Pero di ba sir yang recirculating blow by gas na yan ang nagpapadumi sa throttle body and map sensor natin?

Nope. Blowby gasses goes back straight into the air intake / intake valves. It doesnt pass the MAP sensor anymore. Even if it does - the air filter will take care of it. 4

RE: Positive Crankcase Ventilation (PCV)
can we ask sir @enk to tell us where the location of the PCV is. I have a guess only .. I can't comment till I get hold of the service manual..

Yes sir arjee got to trace the rubber line kung san connected and nakita ko nga din na directly sa air intake na sya which is nice.

ah .. ok, this tube goes to the inlet manifold. I found also there's another PCV tube (after the air filter).

RE: Positive Crankcase Ventilation (PCV)
You are right.. it's a breather tube.. the excess pressure flowing back through the breather hose to the air cleaner tube is sucked back into the engine and burned. But then this is not clean air.

I think, this satisfies your statement why the MAP sensor gets dirty.
