Catch can help!

[Viperrmk]

So I have a UPR catch can installed on my P1SC. It's on the passenger side and the drivers side is capped off. A little while ago I emptied it out and it was full of mucky/ cappuccino looking crap. I cleaned it out and re installed it. Well I checked it out today and this is what I found after 400 miles ( picture below). It smells like fuel, which is understandable cause it's blow by. But it looks like it has a little water in it.... I don't know, does it look normal? I pulled the dip stick and the oil looks clean.

Sometimes you will see water during the winter time. Especially if you take short trips. It's probably nothing to be concerned with.

Ok that's kinda what I was thinking. Just condensation maybe? I live in Miami lol it doesn't get cold down here. I do only drive it on the weekend for maybe 10 miles and that's about it.

That's due to reduced circulation of air through the crankcase, where in clod weather, you'll get condensation inside and it blends with the oil and looks like 'baby shit'.
Remove your oil filler cap and look inside, and you'll probably see some, too.

The solution is to: (1) wait until warmer weather; (2) get more suction on the crankcase to remove more of that lingering moisture.

Of course with f/i this can be a challenge since we are no longer using full engine vacuum to evacuate the crankcase vapors.

The procharger setup really complicates it imo. I ended up running mine with a catch can and extra pcv on the drivers side and had a remote breather on the passenger side. It worked fine. The 3v motor is designed to take air in from the passenger side and expel it through the driver side. The only concern was unmetered air but it was a non concern. The small amount of air coming in through the passenger side was a small percentage compared to the air coming from the throttle body. It worked for me. I monitored fuel trims and a/f to make sure there wasn't any undesireable affects from the setup.

Take it out and drive it for an hour or more. Cruise up to Lauderdale and back. Then check it.

It has been very humid though. A lot of rain. Maybe that contributed to the moisture situation?

I just noticed this a week ago on my kenne bell 3v. Looks milky. Car runs flawless.
