Is it really beneficial to install an oil catch can, if the car already have like 100k? If so, do you need both passenger and driver side or just passenger side?

At 100K mi / 160K km, I'd say no. It's difficult to see the benefit of one now. The juice is not worth the squeeze.

My initial thought would be to pivot to the MAF sensor and clean that, if not accomplished before. And review the Maintenance Schedule for any major milestones.

If a catch can is considered...

- V-8, non-modded street applications will use one on the passenger side only (LHD cars)
*Driver's side only for RHD cars (UK, AU)

- If racing (track or area with turns), both sides

- In a boosted application, check with the TC or SC maker

I'm ignorant as to the consensus on drag strip use, but I'm hopeful someone with experience will see the thread and comment.

I also attempted to

If you haven't already done so, visit the thread above. :like:. :clap:

Probably not, depending on your modifications and goals however, with more mileage and engine wear is when blow by and increased oil consumption will begin.

Preventative maintenance isn't a bad idea. I would throw one on. You can probably find a used one for a good price.

I don't see why not. They're cheap and lots of used ones out there.
Clean your MAF, Intake tube and Throttle body and throw one on. And you could always go a step further and remove the Manifold and clean the excess oil. Why let more oil accumulate if you don't have to.

Ok don’t listen to most of these comments because they are just opinions backed by what they have seen come out of old engines after 100,000 miles.
1. A 100,000 mile coyote can still look clean inside
2. Without a catch can oil from the pcv system is introduced into the intake system where it mixes with the incoming air and fuel. This will significantly reduce octane. Regardless of how long you have been lowering your octane. Installing a catch can and stopping the octane loss is something you can benefit from at any time.
one more thing, if you want to completely reverse all the build up and have the inside of the intake, combustion chambers, pistons, valves, and a lot more that I’m not thinking of? Install a water/methanol kit. You don’t even need the methanol at all. You can just run water. If you install the kit at 100,000 miles and have it set to run any time you are over 3000rpm and your engine will be clean like new in 20,000 miles.

Unless your engine's rings are shot and you are consuming the same amount of oil as a 2 stroke, this simply isn't the case. On top of that, catch cans aren't 100% effective, plenty of oil vapor makes it through still.

Thank you, I didn't even know water/methanol kit is a thing! I thought you don't want water to get into the engine?

Has anyone ever tested an engine, back to back with and without a catch can, to see much more knock it sees on 93 because of reduced octane from the oil vapors?

A couple tablespoons of oil/water/fuel, over the millions and millions of combustion cycles your engine is going to see in say, 5,000 miles doesn't seem like it would affect much.

people have used water (or trans fluid) to do the "Seafoam treatment" for years

a very small amount of water won't hurt your engine, and can actually cool/clean the intake. People also inject things like methanol, rubbing alcohol, etc.

you just don't want enough water in there to hydrolock the engine. Not going to happen with a fine mist that comes out of a water/meth setup

for the minimal cost of a Catch Can, go for it. Plus its just another "mod" and reason to get under the hood and turn some wrenches on the Coyote....fun little project for the weekend mechanic!!
