Oil catch can?

bladz1454 · March 9, 2015

The only thing I didn't like about the Saikou Michi is that it is a completely sealed can...I'm one for taking things apart and cleaning. My biggest concern with a sealed can is winter...I swabbed out jello from my jegs unit, and was lucky enough that in unscrewed. That stuff would not have drained from a petcock.

I've pretty much set upon the CP can, and maybe even the aluminum body...still like to see what's going on in there. I guess my reasoning is that I have the Jegs, I see how it works and how well it works, and the CP is a very similar design (just larger).

No worries, I always drain after the trucks been driving at full operating temp for a while to avoid anything like that.

I could see that...

Did you buy a stock can with the 1/2" barbs or did you have the custom make one with 3/8"?

3/8" can(s) designed for our truck's:

I like that!

I sent saikou-michi an email about availability. I have until June to install a replacement for the Jegs.

My biggest issue with ANY catch can option right now is space. The hydroboost prevents using the master cylinder, and I have a spare battery in the second tray. I'm limited to either a custom bracket floating it between the engine and battery, or drilling and bolting to the alternator bracket.

Yea, I think the final model is complete. He just drafted up an adjustable leg for the bottom support on the can last week so I think after I toss that on, update the product overview - it's good to go.

Maybe there is something wrong with your truck?

I don't think so because of the ratio of oil versus water. I'm getting approximately 2 oz of oil and and 4 oz of water. It's hard to tell the exact difference because of the moisture content but that's close enough. So based on the oil quantity, I don't think there's anything wrong. Being that it's mostly moisture in the drained fluid, that's pretty typical for an engine in the winter time to have a lot of moisture like that. It should settle back down to just oil in the summer. If it doesn't settle back down or if it were more than 2 oz of oil, I would definitely be concerned though.

I plan on getting an inline check valve. What's the value of having baffles in the can?

It's a necessity. It gives the oil vapor something to condense and adhere too. Without the baffles, it's just an empty can that does not do a sufficient job of filtering out all the oil.

I too have gotten a lot of water / oil from my RX can during this past winter. As stated in a previous post, I got nearly 10.5 oz of 50% water vs oil after 1000 miles. I completely agree with your findings. In fact yesterday, I was able to wash the truck and I drained the cc again after about 250 miles. I got about 2 ounces of 50 / 50 water to oil mix.

During the summer, I collected nothing but oil. It is weather dependent in my opinion. I think your engine is fine, it's just the extreme cold we've experienced that has added to the gunk we've collected.

Yeah it's definitely the colder weather. I also drain after driving the truck for a while to make sure all of the oil and water is warm so it flows and isn't frozen or coagulated in any way.

And just to clarify again for anyone that may have misunderstood me, my original point a few posts back wasn't to knock any particular brand of catch can. I was merely trying to state that I don't see any way you could ever go 5,000 miles between drains in a cold weather climate.

Well, pulled the trigger on the Conceptual Polymer can, with the aluminum body and HE filter...I really wanted the glass body, but the aluminum version just removes the potential for me to drop and break the glass body. The aluminum version also provides about double the capacity of the glass version, something like 5 ounces or so.

Because I have the second battery and hydroboost, I need to build a bracket from the fender to the engine compartment, with a knee brace from the second battery tray. Should take an hour or so to build, since it will need bending, welding, and drilling. But I need to wait for the CP to arrive so I can make my measurements...probably install next week.

One thing I was thinking the other night is our use of high grade synthetics...in my previous trucks (colder running diesel), you could literally run synthetic through the combustion process (some guys ran their drain oil through the fuel system) and catch it dripping out the tailpipe because it has such a high temperature tolerance. I'm sure synthetics in the gasser get smoked in the cat, but at what cost?

I also took note last night that someone indicated their tailpipe wasn't nearly as black as it was prior to the installation of the catch can, I looked today and mine isn't as sooty as it was previously either...maybe? If it was from un-burnt fuel, should be worse since we are running the rich cycle longer due to the cold weather?

I think I bought the same CC as pictured where did u mount it can't really tell how and where u mounted it also which hose went where? Thanks

ill take better pics tomorrow. But the top line goes to the bottom fitting by the throttle body and the center one goes to the rear fitting on the manifold.

The Catch Can hoses should be routed in this manner.
