This is BY FAR the best explanation of why using a catch can is a good idea. Please watch the whole video.
I installed this can and it collect 2-3 oz about every month or two. Mild throttle and really short distances 4 Days a week. Gonna start tracking the amounts and time between draining now that it’s been on for a while. The stuff that drains is nasty milky oil crud!! It definitely collects a bunch of nastiness that would be going back into the engine!!
Here is pics of draining the can just now!

Definitely humidity, climate, off roading, open cold air intake, not well maintained oil changes or filters, bad fuel, cold starts, and Gen 1 3.5EB didn’t havt dual port injection. So dirty valves.So has anyone figured out why some trucks have a lot of blowby and others do not? Is this simply differences in the piston ring seals? Or is it a sign of premature wear on some trucks?
I think most agree that short trips in cold or humid climates produces the most amount of junk in the CC.

Hey man, I live in NS and I drain mine once every week or two. It really depends on how much blow by your motor allows and how much water condensation you get as well. I don't get much water in my can therefore longer drain intervals. It's mostly oil/gas mix so it doesn't freeze.quick question so i dont have to start a new thread - I remember i looked at catch cans way back when (RX or RXP i think ) and i was about ready to buy but then got worried i would forget to drain and wreck the engine...anyways i am now having fuel in the oil issue, had the TSB reflash of the ecu and its back ... they are going to look at more expensive bits next and i would rather take that money and spend it on a GOOD catch can setup with a HUGE can as i am in Canada and the winter i am told will have me draining daily if i do not buy a big one. Can someone point me to a registered vendor who we trust as theres lots of copys these days. Also do members of the forums ever get discounts, i could use them thanks to our lovely exchange rate and delivery costs
