Oil Separator Necessity??

[badass03ragtop]

Don't flame me if this has been addressed before. I looked and couldn't find an answer.

Is there a valid reason to put this on a stock car? I mean, is the Coyote that bad?? I didn't ever worry about this before adding forced induction to my cars. There, the pressures developed warranted it. I just don't see it with a stock engine, with low compression, etc. Maybe on an EB because of turbo, but that's it.

Someone please educate me if I'm missing something here.

my 2011 wrx that was making over 100 more hp than it was stock didn't need one. a lot of guys ran them though. i thought of it as a fad. but i see guys here running it on their NA GTs. i have no idea why.

Exactly my point.. I've modified a lot of engines over the years, and until adding forced induction to me '03, never used one. Those builds include other FI applications as well as high compression motors.

The Coyote is really not a low compression factory motor. At least I don't think it is.

I can't answer your question other then the fact when looking at the amount of oil collected after 1500 miles of driving, seems worth it to me.

 

[badass03ragtop]

I've had zero oil loss over 1000 miles.

I've only considered 12:1 and higher to be high compression, so the Coyote's 11:1 is just about there, but not quite...

Just pulled the intake manifold from my 2011 Coyote and looking at the intake ports and valves they are spotless after 33,000 miles. I don't think a catch can is necessary.

Great to hear!!

I never put catch cans in my cars, no matter what. Just more clutter for the engine bay. They are popular because they are an inexpensive and easy modification.

People get a sense of gratification when they see the oil that has accumulated over time. But the math says that divided up among the 10's of millions of combustion cycles that have taken place over this time, the amount of oil going into the chamber with air/fuel would probably be measured on the molecular level. no supporting data here, just guesstimating.

Here is a photo for anyone who's curious. Sorry I forgot my good camera, best I could get with my phone.

We need to help you clean that engine...LOL!!

Thanks for posting pictures. Good to see. Looks like I just saved myself $200 bucks .

its only a prob on DI engines as the gas addatives and cleaners will never reach the valves and passages i had one on the camaro

Thanks for the pics. Not going to spend the money.

BTW, jusdging from your pics, I see you live where sand is a problem also.... Hate that shtuff... Gets into everything.

Agreed, it's a waste of money. Switched to a Boss IM on my 2013 GT at about 56,000, and the stock IM was totally clean. OCCs aren't necessary for these cars at all when they're NA at least.

 

[Budwise]

It depends on the conditions in my opinion. For every person who has pulled their intake and found it squeaky clean there's another who found an oil film on everything.

We caught 5-6oz of oil in our catch can after only driving the car for 3000miles.

This is what we ran on our car N/A.

We now run the Procharger Specific kit with a different can since installing the Procharger.
