Interesting after 3.5k miles my oil separator

Has quite the blow by oil inside it.. good thing is I change my oil every 5k-7.5k miles and it looks nearly new out of the bottle in the canister but with that said I definitely wish I would’ve done this before 150k miles now

 

Wow. If you went offroading with that amount, all that might have been dumped back and cause hydrolock . Think steep inclines .

 

So the catch cans are bad if you actually off road? Please correct me on this*

 

Just don't forget to emtybit prior . Theres a member here whose engine hydrolocked while offroading due to that . He posted it here somewhere

 

Liquid is bad.

 

I’ll stop drinking water

On a serious note… I’ll just research this a bunch so I can actually learn the purpose of what the catch can is for!

 

Here. Just don't forget to empty it regularly. I have one again same brand and I just empty it often. https://www.tacomaworld.com/threads/blew-‘er-up-on-the-trail-last-night.765139/

 

I’m pretty sure the JL has a valve that does not allow it to be dumped back in but I could be mistaken.
That fear though is actually why I checked it after 3500 miles

 

Here's mine after approximately 2000 miles

 

Absolutely no problem when that stuff gets re circulated into the intake…

Use the right oil and intervals and all will be good.

 

It’s helpful on DI, or high performance engines. On Tacomas, it’s absolutely useless to be honest.

 

Lol again. And again.

 

But but those 30 mil of blow by is gonna shorten the life span on the 3.5!

 

what is that little gizmo? My 4 banger ain't got one.

 

4 banger don’t need one either

 

Good to know...

 

Carry on sir

 

Good beer

 

It’s the off camber situations off-road that will blow up the 3.5. For example idling for 5-10 minutes and it doesn’t matter catch can or not. In those situations it will blow quicker with a catch can.

 

So, my thinking is, the OP is showing fairly clean oil at 5K miles.
We also know that soot from the detonation is what makes the oil dark. Not dirt. Not metal shavings.
We also know that a bit of condensation gets into the intake, and even tho the heat will cause it to harmlessly evaporate, the catch can gets it while still liquid and adds to the lol bit of oil.
We also know that if there is enough soot in the oil it will turn to sludge and then varnish and all kinds of bad things.
So change the oil filter at some interval to get rid of metal, change the oil at some interval to get rid of the soot. Wait, what did the catch can do? The one that zero OEMs have on a NA engine? My vote is, the purchase of one helped a small business. That's all.
