Ford catch can update. First check on cans

[Roughstock]

Hi Everyone,

I checked my Ford Catch Cans the other day after an oil change. Not entirely sure how many miles I put on before the check since it was between oil changes and I did not note how many miles when I put them in. I thought I reset Trip 1 or 2 but it didn't look like I did. I will recheck tomorrow. I would guess about 2500 miles.

There was nothing in the drivers side can - bone dry. The passenger can has some oil. A very small bit on the on bottom of the can.

You can see here with the tow pics.

I am happy I put them in. I will have a better report at my next oil change. I will be putting engine through its paces before then for sure.

I think your findings of the passenger side canister with some oil collection, while the drivers side has none, is as expected and normal for 2500 street miles. The passenger side canister outlet air tube connects to the intake manifold behind the throttle body, which is post both turbo's therefore maximum boost. The drivers side outlet air tube connects to the drivers side intake tube pre turbo therefore has less vacumn pulling the air/oil mixture through the drivers side separator canister. I'm guessing this may be why the aftermarket single valve units are all separating air/oil from passenger side only. With usage in the higher RPM's the drivers side canister should have oil collection but may still be less than the passenger side. So the passenger side is primarily avoiding oil/carbon collection on the intake valves while the drivers side is preventing oil collection on the drivers side turbo vanes, intercooler and the also the intake valves however it's also a lesser air volume. This is how our engines were engineered/designed as the canisters simply insert into the existing valve cover breather air flow to separate the hot oil evaporating mist from the air.
