UPR oil catch can drain mod project

[dnt1010]

Looks like UPR has has an option for a drain plug but it is like a 30 dollar add. I just ordered one without the drain knowing that I can easily drill / tap and add a valve if needed. Will depend upon the frequency of having to empty it if Ido that or not. Old 6.0 at 264k has a lot of piston blow-by and makes some hefty gnat smoke at times plus she will foul a spark plug occasionally LOL. Just want to make her last a few more years if possible.

Would there be any downside to leaving the drain open all the time?

Yes you will have a vacuum leak in the system and your vehicle will idle weird trying to compensate for it. Also you will be pulling in unfiltered air into the system through the catch can.

Great discussion, as always. Thank you TYForum members.

Took a quick look at provided eliteengineering.com link from post#10 and came across the "New GM Truck E2000 Catch Can."

My ext. warranty is up in about 13k miles; oil catch can is probably the first thing I will add-on once it expires...

Safe Travels!

I put the valve on the end of the drain line. It can be accessed through the driver’s side fender well.
