2020 R Oil Separator

[proeagles]

New GT500 comes with one.

I thought this was a GT350R, different engine, different requirements. One could certainly assume they figured something out after all these years but why not start putting one on the R now? I just come from a if it ain't broke don't fix it mentality. Lord knows I've wasted ton's of money in the old days hot rodding everything I bought. These new fangled cars are hard to improve on. Sure the manufacturer's leave a little on the plate for warranty purposes but now days the gains you get from the aftermarket aren't really all that significant, at least for my money anymore. My GT350 is the best hot rod I've ever owned just like it is.

The GT350/GT350R Owner's Supplement for 2019 says, in the Track Use section: "Note: For track day use by a highly skilled driver, we recommend that you add aftermarket sealed oil separators (catch cans) to the PCV lines on both banks of the engine."

Pretty clear, really. I think every model year since 2015 has had this message, but I can't find it in the Supplement - there was a separate card with the car that talked about track setup, and I expect that's where that message was.

So, for everyday driving, there's nothing wrong with adding one, but the penalty is that you have to maintain it - unlike the 2020 GT500 unit, you have to drain it from time to time. The GT500 unit drains itself.

The debate about port vs. direct injection is irrelevant to this discussion, by the way. It's about the question of "will oil mist in the PCV system create carbon build-up on the back of the intake valves?". DI engines have this problem, PI engines don't. The situation with the GT350 and other high-end performance variants is about carbon build-up in the cylinders causing pre-ignition or knocking which can destroy the engine.

Only with track package Ford include oil separator. It's in the trunk, dealer will install it if buyer desire so.

Yup, was just saying ford made them for a reason.

Well there you go, I knew someone would finally read the manual/supplement and get a answer. Makes perfect sense if you track the car regularly.

I don't track mine often but I got them the same week I picked up my car. The passenger side catches quite a bit of oil vs the drivers side. You don't want that stuff in your combustion chamber effectively bringing down your octane rating. I have always gotten some sort of catch can on my last 5 vehicles including my truck and they have all functioned as intended.

Build up from what ? from the infinitesimal amount of oil vapor that is inhaled by the engine when you run it pretty high up in the rev range? It is also the moment when the highest debit (volume / second) of fuel is spraying in the intake, and the dilution ratio is way way more than a trillion to one ... Me and a friend had calculated that considering the amount I captured in 3000 miles of driving ... After that mileage which included 2 track days I barely had less than 1/4 of the catch can in it (passenger side, driver side was completely empty and clean. I removed it and never installed on my R since).

My opinion is that they are a waste of money and time. I do run one as I am a tweaker and I like to play with things. I think the only reason I like to have it is to keep an eye on the PCV system health.... None of the high performance engines from brands like BMW, Porsche, VW or Mercedes run catch cans from factory...

Just my 2 cents.

So don’t even get 1 passenger side one?

I did get a passenger side one... still have it from my previous track pack. I empty it every year before dropping the car for storage in winter; but I don't clock more than 2000 miles / year on it.. I doesn't hurt I suppose. It's like a massage for a wooden leg

Yea I’ll be doing less than you per year. Just was wondering if you think it’s worth it for the longevity of the car and the protection it gives.

 

[pilotgore]

What is the procedure to drain the passenger side Ford performance one? It looks like the JLT you just unscrew the canister at the bottom is that correct ? ( it just does not look original under the hood with the black polymer though) ?

1:55 of this video from ford performance shows how to empty their catch can:

It’s a pretty decent little video that explains its purpose.

I like the girl in Ford Performance video. She hypnotized me buying third oil separator.

I installed a passenger side FP separator today. I was curious is the OEM line to the crankcase had any residue in it. No oil or liquid was apparent. I swabbed the inside and the swab was clean. Mind you I just hit 2K miles in 11 months of ownership and street driving only (and occasionally spirited north of 7K rpms). No sign of any oil consumption at this point.

 

[RJay]

I can tell you they work.

Left = 2000 after oil change
Center = 4000 after oil change
Right = 6000 after oil change

 

[lenFeb]

I have FP oil separator passenger side installed since I purchased the car and had some oil in it. I was checking the driver side hose and it was dry. When I checked yesterday I noticed some oil inside drivers side hose. Just purchased driver's side as well, will install when the oil separator be here. I drive spiritually on back roads mostly between 3-5K RPM, occasionally reving to 7-8K.
