Oil catch can install how to on the Boosted Miata 

Artoast thanks man!

+Buda Bunda thanks!

cheezy_popcorn thanks!

cheezy_popcorn thanks!

Josh Foster thanks, I will do that. pretty sure it's empty. I've also got a better place and way to mount it.

Aaron Hurst that's a homemade heatshield from an old smog check sign (irony?) covered in an adhesive heat foil from summit racing. :-)

+Blue B6ZE Yes if you want to be emissions compliant. Otherwise it doesn't matter.

The reason for the 2nd vented oil catch can is because its a turbo car and under boost it is no longer getting vacuum on the intake manifold(where the other can is connected) its actually under pressure so that can is likely having its oil blown back into the valve cover under boost. So you do a 2nd can that can allow blowby air to go to atmosphere. Thats my understanding. Normally the PCV system has 2 hoses to the valve cover. 1 allows filtered air from the factory airbox to enter the crankcase. The other hose has the check valve(CHECK VALVE) on it which pulls blowby gases under engine vacuum into the intake. Ok wait. i just realized that the PCV eill normally prevent or minimize boosted intake air from blowing through oil catch can back into the valve cover. Some guys on youtube say to remove the PCV valve on boosted cars but they forget its there for a reason. Leave the check valve in place if adding an oil catch can.. thats just my 2 cents on this. i never installed one but worked on plenty of cars and understand the theory of operation. It makes sense.

greeenteeee I need to get under the car and check. nothing pouring out like before though

The rad cover is from garage star, they are out of business. You can get a similar one from Goodwin racing: www.good-win-racing.com/Mazda-Performance-Part/61-0150.html?gclid=Cj0KCQiAu62QBhC7ARIsALXijXTkqdxXdBaJ2EtcIVHsfinjrQYrwsKzTEhZuO33z7mf0gXTTIRWgTEaAvAcEALw_wcB The scar on my wrist is from multiple surgeries to repair a severe fracture - complete success btw!

@@Seandoestech Holy heck.

+Tanawat Oonwattana you will lose some under boost. If you are.not boosted, you likely will not have enough pressure to force oil out of the crankcase vent.

Boosted Miata Thanks Shawn for the reply, much appreciated :)

Hey boosted miata, I really enjoy your videos and wanted to give you a good idea to improve your cheepo catch can. Affix a metal straw to the one port so the oil and air vapor is forced to the bottom of the can, then also fill the can with steel wool. tada! now its doing just as good a job as the moroso brand one.

+Buda Bunda 2001, 2350 lbs, 230 hp, haven't timed it, fast though off the line.

+juan visuete see part 2, running it into the air intake.

thnks sr. i do other way but the same way .

MiataMods yeah, it's not so bad as I was first thinking.

Steven Trafford no

Built For Boost - great explanation! 👏👏

Yeah - just be safe. I have a roll bar, so it gives my family more peace of mind.
