They make 120 dollar hemi catch cans, and they make just universal catch cans for 20 dollars. My question is will the 20 dollar one work just as well as the 120 dollar one. I can post links if that helps.
Thanks
Just a couple things to read/understand from those that are in the know about catch cans:
From another Jeep forum, a quote from Mike at Diablosport, the tuner manufacturers:
"No, this is where I comment on lost power due to oil contamination in the intake tract/combustion chamber. I will assure you that after having seen as many logs of as many HEMIs as we have here at DiabloSport, not to mention the numerous HEMI vehicles we have had on our dyno for R&D, I can say, without a doubt, that the HEMI's PCV/Oil Vapor control is the worst of anything we deal with. All you have to do is pull your intake manifold to see the puddles of oil collected in there, and realize that it eventually gets in the combustion chamber, and oil don't like to burn, thus, detonation occurs.
There is no gimmick here. HEMI's have KR issues. The KR issues are 99% of the time contributed to by oil contamination in the intake charge, reducing the effective octane in the combustion chamber, and leading to a loss of performance."
Plenty of people have seen solid power gains on even stock vehicles when getting rid of an oil issue by adding a catch can that works properly.
This "Bible" is from Arrington Performance.....Hemi Specialists:
I didnt mean to imply that catch cans werent valuable. I have two on my airplane, but in aviation they are called "Blow-by oil accumulators" and "Catch Cans" are what hangs off the bottom cylinder of a radial engine to catch the drippings that let you know the engine has oil in it. hahaha..... but this aint aviation.
I recognize the value of the catch can on the hemi...based on multiple threads of deplorable oil consumption.
My only question is...assuming that there is a $20 can option...is the $120 can 6-times better at doing the job? Its not about if I CAN spend an extra $100 for a can. its about if the more expensive can is WORTH the extra expenditure...does it do something that the less expensive can does not do. Yeah...its an expensive vehicle...but I didnt get to a point where I can afford the pricey buggy by making emotional or ego driven decisions with my money. I CAN run Perrier Water in the washer fluid to prove I have money....but if it doesnt do a better job, then its just a waste of dinero.
Looking cool has its place...I agree.
But Im not gonna be hanging out at the corner stopping passers-by and saying: "Hey, buddy...wanna see something cool? Come look under my hood." hahahaha
Again...if its worth it...awesome.
However, If it does the same job....I dont buy hype. I dont know whch is the case...and neither does the OP.
Thus the simple question....does anyone have experience with the range of catch cans....and is there a difference in effectiveness.
Its just a question...not a witch hunt.
I dont think the OP and I know that I am certainly not trying to make anyone justify their decision to pay more, when a cheaper option MIGHT be available. We are just wondering why so that each of us can make informed decisions.
I purchased and installed a Moroso catch can some time ago. The reason I chose this one was the ease of emptying it. The extra cost was worth it to me. See attached..........
Hi,
For what it's worth I have used both a cheap ebay type can and a BT. Both cans appeared to scavenge about the same amount of oil. This was not S controlled comparison just looked around the same 10mls per 1000kms. This on the 3.0l Diesel.
For me the BT can is more elegant and easier to mount and empty.
Pete.
I wouldn't go cheap on my truck so i prefer the BT. Yes it fits tight under the hood but still easy to empty. After using other well known brands and BT and the amount of oil that is collected and not going into my intake, i would gladly pay that $125. That is if you plan to keep it, if you will trade within 5 yrs then its a waste.
At the end of the day if your curious, its only $20 so give it a go and if you no likey, then buy the good stuff.
Watch this video and decide which catch can is easier to empty......Moroso or Billet. On the Moroso all you need to do is turn the valve with a cup under it.
What's the capacity of the Moroso can? The Billet is about 4 oz., but the Moroso looks a little smaller?? I have Billet cans on both my Hemi's and I don't have to loosen bolts or turn the can top to empty either one. My LX has it mounted like the video, and the WK's is mounted to the strut support brace. It takes me longer to drain and wipe out the cans than it does to remove/reinstall them. That video showing the bolt loosening and turning the top is BS. I have big hands too. On the Moroso, I'd also be curious how you get all of the "mayonaise" out in the winter. It's pretty gunky and slimmy stuff and does not flow very well. In the summer, it wouldn't be a problem though, unless you're in a real wet climate. I agree to that $20 for the cheapo isn't a big deal, so why not try it and see for yourself. In any case, if you have a Hemi, put something on it for sure. The choice is yours.
Edit: Also, topat46, on the Moroso, how often to you empty it? In the damp winter I'll sometimes empty them as often as every 800 miles (depending on how damp out it is), but in the summer mine will easily go without emptying between 6000 mile oil changes.
It actually handles the mayo very good. I just put a plastic cup under it and let it drain for a while. I think the Moroso may be larger than the billet (not sure of that) but can hold at least 8 ounces according to the attachment here.
OK, here are the approximate differences in dimensions. The Billet unit is about 2.5 X 4.75 in. and the Moroso is 3 X 4 in. Maybe some math whiz can figure out the volume in oz. based on the measurements. It's way beyond my simple mind.
I think the important issue here is that they both work (which I know they do). They are both made to last a lifetime and look sharp under the hood. I purchased the Moroso because of its ease of draining.
I prefer the Billet tech, removing the canister, emptying then spraying the inners with brake clean to get all the mayo and gunk out of the bottom. I empty it a few more times during winter, since condensate fills it more quickly.
In this particular thread is the only information I have on Catch can sludge etc.
But based on everyone's descriptions, this sludge stuff seems to sound a lot like condensate discharge where oil mixes with water.
Again that's pure conjecture and just thinking out loud.
But I am curious if anyone has any thoughts on the wisdom or lack there of of pouring the captured sludge back into the oil filler port; that's where he came from.
Then, it just gets emptied when you change the oil and the filter.
I'm absolutely certain there are probably a number of reasons why that is a horrible idea otherwise everyone would be doing it. So I'm simply inviting comment on how and why.
Putting it back in the crankcase, has to be a hell of a lot better than putting it back into the combustion chamber.
The BT instructions specifically state not to pour the contents back into the crankcase. I empty mine into my oil recycle container (old 5 gallon gear oil bucket).
Sorry for the newbie question, but would this work on any petrol engine? What would the advantages of installing something like this? Thanks for educating me, and maybe others that are looking forward to know!
