Coyote 3 Oil Catch Can

[Fastfwd]

Is there anything in particular that you need to take into account when choosing an oil catch can? Any particular feature that might make one brand and/or model better or worse than another? Or will any of them do just fine?
The JLT ones seem to be held in high regard, but unfortunately they don't ship internationally for the time being, due to covid. Steeda also offers one, which I would prefer simply because of the convenience of having it delivered from a European location. Does any of you have any experience with it? Is it as good as the JLT (and if not, then what exactly makes the JLT better)?
The only thing that draws my attention is that the products of other manufacturers, including JLT, are specifically made either for the driver's or for the passenger's side, while Steeda's catch can is generic. They say it can be installed on either side. Should I be concerned about this? I mean, there must be a reason why others choose to go through the trouble of designing, manufacturing and selling two different products for the same car, mustn't it? So what's the catch?
Any hints and tips would be appreciated, as I know next to nothing about these things.

This dude on Youtube compares the Ford Performance oil separator to the JLT and some other option. It looks like the Ford Performance has superior filtering and overall design, but I'm sure that is debatable. That's why I went with the Ford Performance option.

Best are the UPR and Bob's Auto reliably.

JLT are all over and often put up for sale. I know they went through several recent iterations b/c the ver1 and 2 did not perform up to UPR and Bob's standards. I do not know about JLT ver 3. In serial testing, the JLT id not catch as much but that was with prior to ver 3. Could be they finally got it right in ver 3. Do not know.

That said, placement is everything and size is important. the cans rely on being in a colder place to catch more. Place it over the exhaust manifold or a hot spot and they cannot precipitate the vapors. Simple physics. Cool conditions help precipitation. Larger can seem to also help.

Some will comment having a stopcock on the bottom instead of unscrewing are easier to empty but that is dependent on having access to the bottom and again placement affects that.

The best mount would be in front of the radiator or along side where cold air comes in but that can make emptying difficult.

Ford Performance for me :

At this moment in time I want to keep with the OE look

isn't the FP can a plastic can mounted right behind the hot radiator or is it under the hood vents?

 

[WD Pro]

It’s kind of almost under a vent, but I’m not really sure how much of a difference the vent would make ... ?

If I need to install one, I'd also like to go with the Ford Performance one... but it's a different one than on that video, at least for the Bullitt (but probably for any 2018+ V8), which installs differently. The guy on the video also didn't seem to realize the maximum oil level is below the lower output, which is quite low into the can, so the volume is actually quite limited. I think it's also like 1.5-oz (like the old JLT). Curious if somebody has measured it, but I'm sure Ford has to list its capacity somewhere, no?

I might install one, even though my car doesn't seem to be burning any oil at the moment.

Thanks, guys. I will take a closer look at the Ford Performance one. That looks like an attractive option.
I understand that a catch can is only really needed on the R/H side of the engine (i.e. passenger's side in LHD vehicles). Why is that? How come no oil vapours are collected on the other side?

How come no oil vapours are collected on the other side?

I don't know why, but I've seen a couple of youtubers who took of their seperators after around 1000 miles and there was noticable difference in the catch cans where there was more in the right side.

I will take a look in mine in a week or 2 when the odometer hits 1000km on my car and probably measure the amount of oil.

When I picked up the car I installed the right side at the dealer and took a look when arriving home after 150km where it was just moist with oil inside - I figure there might be a small amount in the can itself now

Thanks, I've ordered a Ford Performance one.
Apparently Ford Performance only makes a R/H side catch can. Try as I might, I couldn't find one for the L/H side - not for the 2018+ GT anyway.
I'm still curious as to why the driver's side doesn't seem to need one. Surely the pressure inside the crankcase can't be higher on one side than on the other, can it? Why are there next to no oil vapours on that side?

The passenger side is hooked to manifold vacuum. It gets crankcase air sucked through it all the time. The driver side gets filtered air from the intake tube.

The only time the driver side see's crankcase air is under WOT conditions.

I see. I thought both hoses were connected directly to the intake manifold, one on each side. But actually only one is connected to the manifold, and the other to the air inlet tube, right? That would explain the difference.
But then, next question: if most of the oil vapours are sucked in through the passenger's side hose, while the other hose gets next to nothing, then couldn't we just remove the driver's side hose, plug both holes, and forget about it? Would that break anything? Would the pressure in the crankcase increase dangerously at WOT?

 

[K4fxd]

Yes, pressure would build until it blew out the oil seals.

An update from Denmark!
I hit 1000km in my car and took out the catch cans.

This is a picture of the amount of oil that was in the R/H side

It is a very little amount but just thinking of this would have been enden up caking in the engine over time makes me happy that I installed the catch can!

The L/H side is not worth mentioning... it was dry - as in BONE. FREAKIN'. DRY. I even wiped my finger in it but it was as clean as when I installed it.

And for good meassures - I have the JLT 3.0 catch cans on both sides
