VMP built E85 car, but no catch can?

[Snoopius]

I run JLT's on both banks, but really only need the passenger side. I check/empty it about once every few outings and empty an ounce or two of fluid. Simple. Easy. No tools. Just twist it off (with a rag for grip) and hand tighten it back.

Do you have a rough idea of what "every few outings" translates into miles by chance? The JLT I believe is a 3oz unit, so with my car being a street car I'd imagine it'd fill up fairly quickly. This is honestly a big factor in why I'm assuming the car doesn't have one on it currently. It seems like too big of an oversight for VMP to not install one without a reason like that. But that's a lot of speculation also.

Believe it or not, you don't NEED a catch can. The NA guys circlejerking over them is par for the course.

I have nothing to add to this.

The original JLT reservoir was about 6 FL oz and they make an extension (basically a threaded cylinder that you can add between the upper assembly and the reservoir that doubles it to 12 FL oz if you find that necessary. I change mine often enough so that it's not really a thing. If I go a long time in between checking it'll be half or 3/4 full.

The beauty of the JLT is that it's so easy to check so doing it often isn't a huge burden or pain in the ass. It's about as easy as checking the oil level and I generally do them both at the same time.

6 Fluid ounces is about 20% of a quart.

The only reason to run anything large is if you're going a LONG time in between checking it or you just have really bad blowby.

It doesn't seem like it. I tried to pay attention to that range in a few different gears today and nothing stood out to me at all.

When my feedline was routed to the regulator first I had a bad lean spot. VMP used to sell a kit to reroute it.

Could be an older build from the late teens. Catch cans became really popular in 2019-2020. Now every Mustang has one.

You need to get a vent to atmosphere catch can so you don't pop a ring land. You can guy one that does both valve covers. I have two catch cans, one for each valve cover and both vent to atmosphere. I'm also going to remove my PCV since it's not needed now. I just can't find a dummy male nipple.

Catch cans were popular many many years ago. I had one on my ws6 in 2010 and my cobra in 2013. I think newer people into the car world just found out about them when they started looking at mods for their first muscle car, in 2019-2020.

Every coyote I have pulled the intake manifold has been full of oil. So I use one.

Are you guys really all paying $500 for catch can set ups? Seems kinda insane for what it is

Well can't speak for everybody, but my Ford Performance pass side catch can is doing it job. About a tablespoon every oil change ha-ha. On the plus side the intake is dry and the valves are clean.

Must be non-E85 I'm assuming? That's part of my hesitation for my car, sounds like E85 fills the can up extremely quick.

E30, mostly.

Has little to do with fuel.

Has to do with aeration of the oil and drain back on the passenger side combined with crank case pressure flow. There's other aspects like allowing the motor to engine/brake rev down and conditions that create more crank case pressure (as well as how hard you run the car and for how long) but here is one of the major culprits:

This video explains how the tiny gap between the windage tray and not having a "crank scraper" can cause backup on the passenger side and result in lots of oil suspension that ends up being taken along for the ride when crank case is vented on the passenger side.

6:45 to 9:30

It just seems like guys running E85 (mind you this isn't Coyote specific at all) fill up the cans with clear liquid (alcohol byproduct?) extremely fast from what I've read/seen. As opposed to the usual 1-2 tbsp of oil per oil change in non-E85 cars.

I've been running E85 for almost 5 years and my can is usually full of black espresso.

E85 does cut the oil more, but if you let the car warm fully each outing and you give it the full sauce from time to time and never flog it unless it's at full temps, it evaporates off lightweight contaminants.

I don't think it's as simple as 93 vs E85. Has a lot to do with tune, how the car is used, etc.

I heard Alex from Lund say that a lot. But I think it's for high HP/Boost cars.

Is there's a certain Boost level you need a vent to atmosphere can?
I'm looking in a VMP Gen3r but I plan on just trying to make 700HP on pump 93. Nothing crazy,.
