Oil Catch Can. Yes or No?

[HeavyDuty]

Wouldn't this void the manufacturer Warranty?

At 29,000 miles now and I am getting NOTHING in my catch can. I run 5W4O synthetic, change it often, and run an E50 tune. No noticable oil dilution either. This started at around 25K miles and has continued.

Yea it’s a no from me..

My experience to date. When it’s warm outside the CC is mainly oil dribble. However, when the temperature starts to drop below 50 there is this fun fuel water mixture added. Mason jar was empty on 6/15/22.

I find that interesting and wonder why you would get none now. Is it the fuel or the number of miles? Some part of the tune? Low/no humidity?

I'd say a combination, but I would think the miles has a lot to do with it as it should be fully broken in by now.

My opinion is humidity and temperature. I’m at 12k miles and so far it seems to be temperature dependent.

I thought so too, but I am seeing it in all weather.

Yummy. Here is 6 months worth of crud. Looks like a layered cake.

No catch can for me. I prefer clear liquor.

Anyone know where I can find replacement o-rings cheaper than the UPR site?

I saw some post a reply regarding the CC after a tune not catching much. Figured I’d throw my Pennies in it. So 82k miles and into alcohol bottle #2.
back in Nov of 22, I bit the bullet and bought a tuner (bully dog 91 oct). Since then the build up in my can had significantly dropped. I still get the condensation and some carbon but no where near what it was.
For those who are on the fence, go watch the vids of Walnut blasting valves or just the numerous vids mechanics have posted of Ford DI engines and their valves. Worth every penny

Anyone willing want to prove their catch can is working with a little test? Looking for a catch can owner near 30-40k miles willing to take off their intake manifold and peek into the intake valves? This is what 36k miles with no catch can looks like. I want to have some additional data for comparisons. I want to answer the long question of, "HOW effective is a catch can in reality and is it worth the effort?"
