In this video I'm getting rid of the PCV valve due to the anticipated boost as well as letting the valve cover breath and adding an oil catch can.

thank you
ENJOY!!!
Great mod for a turbo MX, I had constant leaks from all over the shop on my engine, binning it and getting a catch can stopped the leaks! I just wish that i knew this A: before i turbo'd the car, B: before replacing seals endlessly!
awww man tht sucks. glad the catch can solved your issues
I didnt even notice it was powder coat when in the car, maybe I will chrome coat one of mine.
drilling andtapping both sides holes 1/2 inch NPT and using a 1/2"npt to AN fitting works well too if if its a valve cover you cant/dont want to recoat
yeah ive seen a few other people do this but because my valve cover had a deep scratch in it i wanted to re coat it anyways so i thought i may as well weld it
Perfect video for what I needed, thanks pal great work
Glad it helped 😎
heat in the catch can is a good thing as long as the components can handle the heat as well.
it will help keep the oil hot enough to boil off the moisture, more important if you were returning caught oil to the sump, but shouldn't hurt anything to be hot.
now this i didn't realize, thank you
Given what usually ends up in a catch can, I wouldn't want that crap going back into the oil. It's a quick way of contaminating your oil.
Good vid, I noticed at my first drift day in my boosted mx5 Saturday, the car ran fine in general but when it got hot after 3-4min session of drifting that idling afterwards it would smoke for a good 30 seconfd and smelt/looked oily. I think it was because on boost it couldn't get rid of the crankcase pressure then on idle the vacuum was sucking in any puddled oil and vapour that was sat in the rocker cover. Mine is still running stock pcv with the open side breather running to the turbo intake. Interested to see how yours gets on with this set up, I still think the vacuum abilities of the engine below boost and on idle etc are handy so not 100% on venting just to atmosphere but may try it like yourself and see if it makes a difference 👍
As soon as it actually runs ill let you know 🤣. Thanks mate
Loving the catch can,, is exactly the same one as i have, in exactly the same place👍👍
o awesome, do it work well where it is?
@@Project380 hopefully lol. Cars still na atm. Whole cars prepared ready to go. Just mani, downpipe and turbo ready to fit then get ecu mapped.
@@jmpcrx 😯good luck
This build is soo neat! Awesome conent bro, keep it up!
thank you 🥰that means alot
Hey man, good video,
all very clear. I had read the huge thread on turbo miata about catch cans, I was under the impression that you should have a vacuum involved, is it the case that with the forced induction you simply cannot get a vacuum any more?
Yeah in an NA situation a vacuum will help massively. But in forced induction it's not really required
Love the progress mate, keep it up 🔥, I guess you shooting for over 300+ whp with this set up (don't know what turbo you are running), would you say that it would be safe to run a 323 turbo pcv valve on a 200-240 1.6 ?
Thank you i appreciate it. yep im shooting for 380whp, yes the gtx 323 valve would be a great upgrade for your power level
Love the content. Where did you get that catch can?
Thank you 😊. Just eBay then modified it
@@Project380 gotcha. Do you have a link by chance?

Hey mate, I'm looking to do the exact same thing with my engine with more less similar power goals, did this setup work?
good luck to you. hopefully ill let you know in a month or two 😂
My Catch can has an inlet and outlet port + small filter on top, is there any difference which pipe I’m connecting to which port?
unless it has a one way valve it wont matter
hello sir, sorry i'm not a native English speaker so i'm not quiet understand. So basically you're just deleted the PVC, make bigger hole for "breathing" and attached it to the oil catch can right? but how was the intake manifold hole (for the PCV hose)? did you just plug it with something?
hi there. yes that is correct.
im using a skunk2 inlet manifold so i do not have that hole for that pipe, but in the standard intake you can either block it or run a second catch can, so it runs from the cam cover to catch can and then from catch can to intake manifold but make sure there is no breather filter in it or else the car will not idle
@@Project380 does the crankcase fume / blowback gases can get out with that setup? Since there is no vacuum
Least now I kno how todo it properly now lol thanks
happy to help 😎
Hey thanks for the video! Hope things are well. Wondering if this is something I want to consider doing on my supercharged v8?
All good thank you. i think any car with added boost should have some sort of breathing system to stop excess pressure build up in the engine
Is there a way for me to relocate a Rev9 catch can where the windshield wiper fluid is?
im not too sure, i belive rev9 is more of a usa thing. but i cant see why not as long as it can vent ok
Is there a performance reason for expanding the pcv diameter when the car is boosted? I have catch cans on my boosted mx5 but with standards pcv valves.
if you still have the standard pcv valve then there is no benefit, if you increase the hole size but not the pcv diameter then there is still the same restriction.
hopefully the way ive done it then there should be no restrictions and better gas flow
do you know if the na and nb miata valve covers are aluminum and safe to weld on?
Yes they are safe to weld but full of nastyness and porosity. So yes you can weld them but it will always be a little dirty
@@Project380 Ok. Do you have to preheat the valve cover before striking the arc? I would imagine it takes a lot of amps to weld these bungs onto the valve cover since the valve cover is so large it needs heat?
If you don't want to weld it, you can drill and tap the hole for a screw in AN10 fitting either.
@@MrManBuzz I prefer to weld if possible but yes that is always a temporary solution
