Not risking a dealer trying to void my warranty over it. Prob unlikely but def a possibility. Mine stays stock until the warranty is up. I dont think there has been a history of gunked up valves yet either in these cars, and many are run very hard. I think if I'd been reading a bunch of posts saying how their valves were all gunked up then maybe I'd think about it. Havent seen any yet. Personally I dont feel the need.

I would definitely run a passenger side one, upr fender mount is the ticket.
A drivers side one is worthless in my opinion, never had a drop in that one and I am running higher boost....

with the ease of taking these things on and off I'd just pull it before any service...with that being said I've been thinking about this as well....well after much interpersonal debate I've decided I want one as I cannot see the fault of having it installed

With port injection, there is no reason for a catch can. How about that? can it hurt? No. Catch can is only for: VW engines because they were made very wrong. Same with early versions of modern BMW 3 and 4 cylinder turbos. Also wrong. Direct injection only + bad engineering = catch can porn time. Direct injection + mazda MX-5 RF (ND2), i have that and its not needed as the area gets over 400 degrees to burn off buildup. Really, only the worst of the worst german "endless money pits" needed catch cans.

A catch can will ALWAYS catch oil and gunk mist. It does not need to though in a port injection engine.

Now, I did not figure this out on my own. Let it recycle and burn off. And just use like Shell 93 and you have super clean valves. The amount of gasoline this sucker sucks would clean off a NY City sidewalk.

Do you want to know what worse than an Australian...An Australian that attempts to use humor whilst making an "engineering" video about oil catch cans. Sadly I agree with the "A-hole" in the video, save for one part, I don't think they can hurt.

I use mighty mouse catch cans in most of our build. They are a little pricey but work great.

Always used one, it's personal preference really. Everyone will have they're own opinion.

Yeah after reading all this and considering that this motor is port injection and possible warranty issues on a 100k car I’m going to skip the can. Thanks all.

I have one. When I went through inspection at land speed trials last fall the inspector asked "what's that". I explained what it was, he grabbed some of the other guys around and they all thought it was a great idea!

this is where I'm at with it...it certainly will not hurt it. It removes in under 5 mins if any warranty work needs to be done. It cant hurt the engine, it can only help it. I'll put one one, although I think the engine is fine without it. These OEM engineers would have put one on from the factory if the engine truly needed it. These are not first year engines, they have these figured out now and with that being said OEM's are not in the business of recalls

Don't forget that OEM engineers are still under the thumbs of the bean counters. How else do you explain putting 275 AS tires on a 700HP car? Or such a squirly rear suspension that requires aftermarket parts to tighten up? As a regular daily driver, yes, these cars function fine as outfitted from the factory--but that isn't how they were even marketed from the start now is it?

it's 1000x cheaper to get it right the first time, than pay for a recall on anything. With that being said there has to be a line drawn somewhere. Everything and I mean everything on these cars are ran thought a risk assessment evaluation in terms of durability, and dependability. If its cheaper to put into service said item and deal with replacing said items via recall or warranty than so be it, vs just doing it right the first time.

Well, then surely some actuaries need to be fired because how many Demon's popped their differential doing warranty-covered activities?

And how many has it been? 10? 20? Whatever that number is, it's going to wind up cheaper than replacing the diff on all of them under a recall.

in reality the only thing these "bean" counters care about is that the vehicle as built can meet a certain price point and maintain an acceptable profit margin at the cooperate level. That includes risk assessment on possible recall/warranty replacement costs. Beyond that, they don't care what goes into them.
