SOHO Catch Can combo

B15specv · 07-14-2025, 08:51 PM

Anyone running a soho catch can combo? I've been running one since November and all it does is blows oil out the filter and never fills up the catch can.

I thought at first I wasn't draining/checking it soon enough but I started checking every day for for last 4 months and nothing in the catch can just oil coming out the filter

Sorry, not sure why it posted twice

Noop, puking coolant out the reservoir, yes. Catch cans should have 10an lines to keep from drawing oil out the engine. Not sure how you have yours plumbed in.

Was hoping someone that actually runs this setup would chime in but I got confirmation from my tuner and he said the samething about soho's catch can combo doesn't catch any oil and just blows it out the filter

I run two RealStreet catch cans these days. They work really well if you have the real estate to mount them. Lines and mounts are custom.

I have the Z1 dual can system and it works great.

I even pulled my intake and sure enough it’s oil free since adding them.
