Just thought I should share....




***Just a tip: For best efficiency use a long hose for the feed from the valve cover to the can, and let it loop around a cooler section of the engine bay. This will increase the amount of condensation before the can.

PUDDING UPDATE!
Total after 3,000 miles, about half a gallon:

 

Can you explain these mod.'s to a n00b?

 

This reroutes crankcase vapors through a can, where it condenses. It reduces carbon buildup in the intake, notably the valves.

 

Good job on the eBay catch can. Paying $150 for a metal can is retarded.

 

ebay catch can huh....hmmmm. i think its worth the 50 bucks

 

Theres a company selling off amazing polished cans right now, in their "going out of business" sale....

check it!

 

Where are these amazing cans located?

 

Was this one of the $9 cans I see all over eBay? I think it's going to be the first mod to my new car.

 

Sweet to see it fits in there pretty good, I just ordered mine, $17 Dollars Shipped.

 

Cool, I'll be ordering one this week.

 

You get what you pay for.

 

Your joking right? This is like when people pay over a hundred bucks for an intercooler muffler delete when you can get an 8 inch x 2 inch pipe for 5 bucks at your local Pep Boys. I would have made my own catch can if the one I ordered wasnt so damn cheap.

 

And you are probably an Alta fan too right??

Do what you want its your car.

 

I'm not exactly sure what that means.

I just can't justify paying a hundred dollars for a little cup that collects oil.

 

onefish isn't exactly an ALTA fan.

 

I guess it would help if people explained why the eBay catch cans are usually junk. A lot of them are empty, just an aluminum can with an inlet and outlet. This setup does not have any internals to help catch the oil vapor, so will catch less than a baffled can.

A can with internal baffles like the BSH or 42DD give the oil vapor additional surface to collect, so you will catch a lot more.

Now if you got a decent catch can from eBay that has good internal baffling, well, good job!

 

No it's not baffled, but baffles are a gimmick anyway. As stated in my original post, run a long line from the valve cover to the can through a cooler area of the engine bay. The critical factor in condensation is temperature, not the amount of baffles there are. If you can get a good temperature drop you will catch a good amount. I just emptied mine out last night after 750 miles and am letting it settle in a bottle. I'll take a photo later.

 

I can see how a non-baffled OCC can still catch vapor, but I would hardly think a good baffling system was just a gimmick. I would think that slowing/disrupting the flow and giving the oil/crud droplets something to collect on would still be more effective.

That being said, I would love to be able to run both styles and be able to compare. I happen to have an eBay OCC that I picked up for my previous car but never mounted, and plan on putting it in the MCS until I get a baffled OCC. I figured it is better than nothing! So hopefully will have some #s to compare in a few months.

 

As I stated, a temperature drop is the key. Plenty of surface area is provided by a long hose. The "catching" happens in the hose, the "collecting" happens in the can. I think this is something that's overlooked even with expensive kits.

The proof is is in the pudding. Results after 750 miles:



At this rate I would need to empty it out every 1,500 miles or so.

Obviously the best solution would be a long hose AND a baffled can, but I'm letting you guys know what the budget-friendly solution is.

 

...and last time I checked Alta didn't have anything to do with this thread.

Tintman: Good to see your getting good results, I'll make sure to run a good length of tubing before mine when I install it

 

AGREED! Ebay cans are hollow....if you want cheap use a pepsi can....thats what your buying on ebay!

42DD is quality and baffled!

 

Sweet, this just arrived in the mail....

My impressions are: It looks to be made from quarter inch aluminum, it's actually pretty heavy and substantial to the touch. Came with a whole bunch of mounting harware but it looks like I'm going to have to get my own tubing.

Has a drain on the bottom w/ O-ring to empty it, however there are no baffles inside. Not too worried about because as tintman718 said, "the proof is in the pudding" lol. I'd highly recommend getting one if you don't mind saving a hundred bucks.

I'll install it tomorrow and follow up in a week to show what it catches.

 

Ehh... with a catch can it can't be too complicated. As long as the welds are good and the user comes up with a solid baffling approach inside the can, the project won't cost a pretty penny.

 

Ok, so it's all done and installed. Went pretty smooth, I ended up spending a total of $25 for the entire install, including hose and fittings I picked up @ Pep Boys. I "baffled" the inside of my can with a bit of steel wool and made sure to run an extra long length of hose on the input side to aid in catching the oil/water condensation.

As you can see in the last picture, I marked with arrows where I had to rotate the can a bit out of the way so that it wouldn't make any contact with my intake elbow while driving. Thanks again to tintman for the idea, I would HIGHLY recommend this as an alternative if you are money conscious.

 

Very clean......
