The easy way to empty your catch Can

OCC’s with a bottom spigot are handy in this regard. That said, a hypodermic IS handy sometimes; drawing out brake fluid from the brake fluid reservoir is another app.

At the risk of pulling a Paul Hogan, I recently shelled out for one of these, works well. Both as a vacuum pump and for dispensing. Well made, about 350~400 cc capacity. See it ended being around $60 CDN, but I’m sure more reasonable in the States.

 

I had the dipstick version oil catch can on our old 2010.

After some use, the threads on the dipstick wear .

But it gave me a chance to learn for the catch can installed on our 2019 Prime:

Oil Catch Can

What did you do to your Prime today?

The bottom outlet valve is the way to go.

 

Bottom drain for me is handy, since my OCC’s are mounted low. I take off the engine bay under-shield during oil changes and they’re right there. Yeah depends on your setup.

 

Nope:



I thought it would take awhile for the threads on the dipstick to strip, but it only took two years.

On the Gen4 / Prime the only real option is to mount the catch can high, given the redesign of the front where the cross member isn't located below the PCV valve and is much further back.

But if you mount high, draining is easy.

 

There's gotta be a way...

 

Take a look at the engine bay photos here :

It is cramped in there.

 

Don't think there IS a blanking plate; deleted that mention.

 

I didn't remember seeing one when I had the intake off.

But I wasn't going to question the resident librarian.

 

Current one is a Tasan Racing catch can and it works well.

Previous one with a stripped dipstick was a Ruien catch can.

I only removed it with my fingers, but doing that many times had effects in the opening.

The original catch can I put on our Prime had a top threaded opening for a breather vent.

When I tried to get ahold of Sporacing who makes the can they said: couldn't be ours as we don't make that.

I learned something and gave very negative feedback on them.

 

I use thread lock/seal with PTFE to seal the threads on my dipstick threads, so hopefully, they'll serve as a lubricant to help stave off thread wear.

But so far I have only unscrewed the dipstick a few times to put an o-ring on it and to install it.

That syringe and long cannula look promising. Maybe I'll try to rig something up. I work in the laboratory so I have access to syringes.

I find it simple enough to loosen the Moroso bracket holding my OCC to the frame below the air box and twisting the can a few times til it drops and I can empty it and twist it back on! Do it same time as oil change, easy peasy…

 

Found this at half the price, doesn't have flexible tubing between syringe and cannula though:

I got one of these a while back, through Amazon, shipped from the States, It's quite big, capacity about 350 cc. Besides drawing up or dispensing fluid, it's pretty good vacuum source too:
