Question about catch can

What's the difference between an oil catch can from like BWoody or BT and an oil accumulator from AGP?

 

Quality and looks. BT and BWoody Catch is MUCH BETTER quality and appreance than the AGP.

Otherwise there is no difference.

 

Function is very important..... and design of how it captures the oil mist. I would "GOOGLE" oil catch cans and become aware that there is alot more to the "function" side than meets the eye. just my 2cs

 

you don't know crap... lol

Steve does bring up a good point though.

 

No need to google. scroll down just a bit for a really nice graphic with callouts. This is a fine can but I'm not saying you should buy it. Any of the quality ones should do as well. It's just that the pic calls out all the major functions. Something to catch droplets, reduced velocity and increased surface area to allow condensation, something to keep traped oil from wicking up the sides or splashing out of the collection area during aggressive driving maneuvers...

Bwoody or BT would be your choices. They both have an internal baffle type system and both work great!

I've owned both pieces and currently have the BT CC, while my wife's SRT-4 has the Bwoody. Can't go wrong with either or.

Oh by the way, our cars need a check valve in place as well as a CC. Bwoody sells the check valve.

 

I guess my question was whether oil accumulator was just a fancy term for oil catch can.

 

lol that would be correct.

 

Bwoody. I like it because its a completely sealed unit looks nice and is small. I am also running the Bwoody check valve.

 

How much do you guys catch with the 4s?

 

When I checked mine at around 3k once when I had the Bwoody one, there was not much in it at all. Sounds like whats left over from a soda can, that's how much was usually in it.

My wife's SRT-4 is running the Bwoody one and her's is the same way barely anything in it. Empty it out about everything other oil change and its not even full.

I just recently, well not too long ago, installed the BT so I will check on that one at the next oil change interval.

 

Are you guys talkking about this BWoody oil catch can?

Weird looking....defiinately different. Why the different shape? Most are round.

 

That is rather strange looking. Any idea what's inside?

 

Actually this is a pretty cool can. The one by Greedy.

I like the ones that have a "sight gauge" (A clear tube on the side of the can so you can see level of oil in can). There is a member that has one built into his BT can, but he had to have BT make a slightly longer can for it too fit. He bought a real nice industrial one with a built-in plug for emptying (If you don't want to unscrew body). It loook real sharp.
I saw a pic somewhere....let me see if I can find.

Here it is.....

 

Yes. But like Sarge said, I wouldn't buy one without knowing what's inside.

 

Sight gauges on CC's are tough.
Depending on the type and amount of nastiness that collects, the gauge can turn brown/black quickly.
The one in my JMB lasted about a month (JMB was cool enough to send me replacement tubing that should last me a good long time).

The McKinney can/design is the best out there. It actually "catches" the crap.
I spoke with them earlier this year about doing a larger one for the Viper engines (approx. 1 qt.). He said it was in the works, along with a viewing window; the polycarbonate they were testing continued to shatter/crack as they ran it around the track.

My recommendation: Drain it each time you fill up the gas tank.
Also, totally clean out the inside (acetone or alcohol or Dawn) every oil change. That will keep the drain valve from clogging and get the gritty stuff that's formed over time.

REALLY nice catch can:

Great price too!

 

I have worked in the industrial industry in a maintenance field for MANY years and I have found plastic of any kind is always a crap idea for a "sight level tube" for almost any type of fluid. It discolors and forms a "fake level" if the fluid is at a certain level most of the time. Glass is BEST.
The one you see in the pic above uses a protected glass tube. They are made by "Oil Rite" and ae usually used on hydraulic tanks.


AMW makes a fairly good can also. Theirs has groves in the inside to keep the oil from "Sliding" up the siide in hard cornering.
BT makes a pretty good can (It think they "reverse engineered" an AMW except they missed the grooves) also but I think there is some room for improvement in the "catch" section.

But you are right the McKinney is best. They let the oil laden air just come right in then they spend more time and material catching the oil on the way out and they trap it well.

 

A quart!?!? You only want to drain it once a year or two? We're catching about 10 ml / 500 miles with the 8's

 

Yes. A quart.

I've had mine 'blow back' during long road trips. Absolute f-ing mess and hours to clean up, in addition to it not being healthy for the engine bay components that get covered in that crap.

The Viper engines produce more 'gunk' than the HEMI engines. Numbers vary, but I'd put it at 2-3x as much on average. Causes range from pulling more air to pushing more fuel.

The pint-sized ones are....okay....but I'd prefer a larger one that can handle long road trips and that I don't have to empty once every fill-up.

 

There's a V shaped baffle inside, almost looks like what companies use for windage trays.
