Is the Mishimoto catch can working?

Hyper1SS · 09-10-2016, 01:49 PM

Has anyone checked to see if your Mishimoto catch can is working and preventing coking on the valves after install? I know the can is catching oil like some have shown. I have not had mine installed long enough or have not put very many miles on mine yet.

Mine is catching an insane amount of oil, so much so that Mishimoto asked me to bring my car in for a once over because they think the engine is burning oil or something... so, once I get the chance to bring it in, we will see...

I see you guys went for the 6spd manual like me. Be aware if you do a lot of engine braking (allowing the motor to slow the car resulting in cool popping and crackling in the exhaust!), IOW just the kind of behavior the rev match encourages, you will accumulate a great deal more oil in the catch can.

The positive pressure generated in the crankcase by compression braking pushes more oil out, I believe.

I get a bit too! Motor slowing (and drag racing) explains it. Empty it often.

Mine is working like a champ! Looks good and works.

had mine in for about 1300 miles now, and I checked mine last night, I would say there is just over a tablespoon's worth in it. I've only floored it 3 times since I've had the car either.

You all missed the point of his post....nobody has checked valves no,not one person has yet to have 20-30k miles with and without a catch can to show factual results.I personally don't have a catch can on my car as NOBODY has proven with facts that one is needed on the ss,nobody has proven it's motor oil in the catch cans either,nor has anyone proven the catch can isn't causing a vacuum that actually sucks oil into it,if you were pouring out a 2 ounce catch can every 1k miles like some of these guys claim,in a 5k mile oil change your dipstick wouldn't still be reading full.not saying catch cans don't work but it's not all engine oil in those cans,and until someone without a catch can pulls a head and shows me caked up beyond belief valves,I'll continue not running a can,like 99.999% of consumers who purchase the car won't have.

All that oil that the catch can catches would otherwise be in your throttle body and intake. I really don't get why some think a catch can, especially on a DI engine, doesn't help a lot...they only cost $100 and have been proven to work. Just go look at Corvette Forums, where they have had the same LT1 for years before us.

Take your throttle body off and have a look at the floor of your intake manifold it will be coated with oil. Its your car do what youd like

Prepare to get "slow-er"

1slowssm6 · 09-11-2016, 08:25 PM

I've been on the vette forums,it's still highly debated there aswell,no proof that it's reduced power on any car whatsoever,yeah we all know about how di engines from Audi,vw etc gunked up terribly in 30k miles,got zero proof the lt1 does the same.anyone who claims the car is gonna become inefficient and "slower" is saying so based off of other cars and what catch can companies are telling you. Anyone here got a head pulled off a car without a can on it for 30k miles with gunk up valves? No? Didn't think so.anyone here got a dyno sheet before,pulled the heads walnut cleaned the valves and dyno again and shown big power differences? No? Didn't think so,all of you Tryna talk junk and come down on me for not having one,have ZERO NADA proof that one is factually needed,or that not having one causes power loss.

Look at this picture. Drained my Mishimoto Catch Can after 10000 miles.
I would say this amount is about 2 to 3 fl ounces of oil. All that stuff would have been sucked in the intake manifold. I am glad to have it installed.

samsumon · 12-29-2016, 02:46 PM

Mine works but makes a hiiiissssiiiinngggg sound . you can hear the engine pushing harder through the can (second one on my car). We think it's my engine performing higher than normal. Dealer said it's fine with no leaks or anything.

MGD · 12-29-2016, 03:07 PM

Hissing sounds come normally from a leak. Where is the sound coming from? From the catch Can? Mine does not make a sound at all.
