hi micwin1437, what if my savvy's engine only has one hole from the crankcase and then the PCV hose branched into 2 hose through a T-joint into the intake manifold and air breather hose..is it safe to block the hole in the intake manifold? would it choke the engine? dun dare to do that I just did 2 OCT each for the intake manifold and breather hose.

Nice DIY! love that plastic water filter but doubt it would fit into my engine bay..

For proton savvy owners just an idea how to make a simple OCT using Iswara fuel filter hose..

After early one month..oil collected, not much - but it's thick and flowing slowly..
