Catch Can!

Sorry for reviving a nearly three year old thread, but this looks to be the big thread for catch cans on 3rd gens.

I installed a JLT can on my 15 limited back in October just prior to a trip from Tucson to Anaheim by way of San Diego. The day before I had also drilled a weep hole that bled about 3-5 tablespoons of oil out, but not sludgey.

Last week I was changing my oil (just hit 100k) and decided to empty the can. I was shocked that in about 6 weeks it was almost full. I measured ~70mL. Again what was collected looked like straight oil. Not sludgey at all.

Is that normal? Should I be checking it monthly?

Did you take a picture of what you collected? How many miles? You gave us a time frame, but not a mileage.

No pic, but it looked like just used oil, no different than what you’d drain when changing it out. Mileage was ~99xxx prior to trip, when I checked the can I was just over 100k.

Edit: Total trip mileage was ~1000 miles.

3oz over 1000 miles, of actual oil should be something to be concerned about. That is a lot. In the winter with idling you will see more, but it will be milky because it will contain more condensation. Get a pic next time.

I’m probably going to grab my current mileage and then check back in a couple of weeks to see what accumulated in that time and check the mileage. We typically don’t do much mileage in our day to day lives, averaging around 12k/year with trips.
