Another oil catch can thread
#142
Instead of a catch can, I plan to add scrubbers in the cam cover:

I also plan to enlrage the tiny 1/4" valve cover hole in the baffling, through which all the blowby gases are forced to flow.

I will say it looks like the VVT cam cover looks as though it is set up a little better. I’m using a 94-97 valve cover on a 99 head and the opening for the baffle in the cover is further in the back corner and it is just above the raised hole in the head to the lower portion of the block designed as the main path for blow by gas to get from the lower to the upper crank case. My theory is in a hard right left turn with a lot of acceleration the oil in the top of the head all goes to that corner and blowby gas ends up pushing liquid oil into the baffle rather than just vaporized oil particles.

I bored my breather out to 1/4" NPT, and used 1/2" hose:

I think numerous people who have flogged the crap out of there cars on the track have experienced the dip stick popping up and a bit of oil spray into the engine compartment by the dip stick. Seen it happen many times.
The owners usually freak out when it happens wondering what they screwed up then they put the dip stick back in and it doesn’t do it again. It is kind of an intermittent thing.
It can also happen very often on a boosted car with a bad PCV valve though and might happen more if you are low on oil.

Solution: eliminated the vent on the intake side that was the stock PCV port and problem dissapeard. I’m just using the valve cover vent that comes out on the exhaust side which is baffled to the center of the valve cover. I also have a vent hose going into the side of the block by the alternator same location as some 1.6l blocks have a capped off port. I also found a PCV valve that fit perfectly to work as a check valve in my return hose to the very bottom of the pan.
What I learned is the baffleing for the PCV port in the valve cover dosn't work. oil must pool up in the back right corner of the valve train where the stock baffling has its inlet on that side.
