Chevy SHOULD have recalled this. It's RIDICULOUS that so many people are having to fix their design flaw to prevent replacing the timing chain and all that goes along with it (which is a very expensive repair - ask me how I know) or blowing the entire engine, which has also happened to plenty of people. I'm gonna be salty about this till I die. ANYWAY... Great video with excellent, clear explanations. Wish I had seen it sooner.
we have done this mod for years here in oz,when gmh were silly enough to put the rattletec 3.6 into commodores.mine was the vz sv6,190 kilowatt with 5 speed auto.good vid mate.
A lot of ppl do this mod it seems to work ok but GM also fixed this issue but never told anyone about it they made a new gasket to go on the valve cover on that side of the motor. they recommend it be installed when timing chains get done by mechanics . instead of having the section over the crank case vent open the new gasket has it mostly blocked off with only a few small holes to let the crank case breath into the pcv valve area making it work effectively. i think if you use the new gasket and did this mod you wouldn't need the catch can as the amount of oil is not going to be anywhere near as much with the new gasket set up.
Even then, I would still use a catch can. There would still be dirty vapors containing oil going into the intake valves which would eventually decrease performance and cause you to have to clean them.
As soon as I got my 2012 Camaro I did the pcv valve and catch can right away want my engine to last as long as it can! I went with the elite engineering catch can and the breather for driver side that replaces the oil cap.
@@great4ever845 the pcv valve the holes are too small and the catch can prevents oil from going back into intake that causes carbon buildup on the intake valves as they do not get cleaned by gas since it is a direct injected motor.
@@great4ever845 it's more so the oil that is in the vapor from that side and if the pcv gets clogged from deposits can cause engine issues like timing chain failure I just did the mods as peace of mind. You can just research about it there's allot of info about it.
The point of the PCV modification is to help the PCV system flow correctly and eliminate oil consumption. Low oil level kills timing chains. The original PCV design is too restricted and the oil gets into the intake through the fresh air side. Fresh air side is on the intake duct and orifice is flows to the intake manifold. Difficult to explain but at least tried.
Interestingly ... I have an GM Holden LFX engine from 2015/16 .. and the PCV valve outlet measure at 4mm so has been well updated and is a clean as a whistle ... engine has only done some 24K Kms and is destined for a swap into an Mazda RX8 (with twin turbos' to be added).
By modifying the PCV valve size you in turn changing the air-fuel mixture. The engine computer is tuned to the exact size of that opening, if you make it larger without a tune, the larger amount of unmetered air is flowing into each cylinder will create a lean condition. A better alternative to drilling, would be to remove the PCV once every while and give it a clean.
I disagree. A hole can only flow so much air correct? The more load you put your engine under, the more blowby gases you have in the crankcase that need to be ventilated. Therefore, Chevy would have to make this whole big enough from the start to handle any amount of crankcase pressure the car would have at any point in the powerband. Lets say they made the hole big enough to account for X amount of air at idle, then under load the crankcase would still build pressure at full throttle because of more blowby gases being present and overcoming X amount of air. I'm sure they made the hole big enough to handle excess pressure at all RPM's and gave it some room. My point is, if you have a 3 inch whole that is capable of flowing 300cc's for example and the engine only put out 250cc's through it at MAX. If we made that hole 4 inches, it does not change what the engine puts out because it is bigger. So Chevy made the pcv holes to get rid of a certain amount of excess gases but they would not allow it to max out every single time because this would still cause pressure build up. There has to be a margin of error to allow no pressure and to allow gases to flow freely. This hole being bigger just makes it harder for carbon deposits to build up and clog it. Now lets say you don't agree with what I am saying or don't understand it. This small difference in size would never allow the engine to lean out either way and is recommended across the world including in Australia and there has been no reports of leaning out as far as I have heard. Do what you want to with your car. To each its own.
I have removed my PCV valve and bought a new one and both of them are empty? there is no valve inside its just a piece of metal with two holes at one end and one hole at the other?
I'm pretty sure our cars are both built on the same GM Zeta chassis too. From what I read that 5th Gen Camaro was the only one made on it. All other Zeta platform cars were Commodores. Hmm I wonder how similar all the bits are across the Camaro and Commodore
Hey man will this cause your engine to drink up more oil because I noticed my water pump was leaking and also checked my oil and there was like nothing it was empty and it’s been like 3000 miles since I done the oil change
Hi Mister Manage. Is this mod is for port injection or direct injection motors ? or both ? Do the port injection motors gum up on the RH side due to small PCV, as well ?
I got 2006 cts and it burn oil like crazy It has 60 k on the engine. I did some research and did pcv bigger holes. Do you think it will help with my oil consumption ? Do I need PCV Oil Catch Can?
I personally would get a catch can because it's pretty much preventative maintenance. A bad pcv system could cause oil consumption. The reason why is if the blow by gases keep building up pressure in the crankcase and your valve is clogged or something is not letting the pressure be ventilated, the pressure will find a way out and that is most likely through gaskets and and anywhere else it can get out. That will cause you to have a bad gasket and have a oil leak which leads to oil consumption. Hope that helps.
Pull it out and check it. It is a possibility. If its clogged, then its possible pressure was not able to get out and cause it to leak or blow the seal. But it could also be a million other things. If you have oil coming from the front, it can be the timing chain cover. I don't see your car so I'm not sure. I'm also NOT A MECHANIC. So take this advice as you will.
Bc of that shit I’m pretty sure that why my timing chain stretch. The engine has to breath so make bigger holes like he said and a catch can. Saved yourself 2000$ do this 😑, that would of been spent for some Apex rims and tires 😵
Hi AJS Porsche. I have a 2009 Commodore VE 3.6 V6 but it's port injection. Is that the same as yours ? This guy seems to be saying this mod is only for direct injection motors.
@@scoldedcat mines a 2007 so definitely not SIDI lol I prefer Port injection anyway. The fuel keeps the valve top cleaner. I've installed a catch can and what not on mine also
@@scoldedcat this mod is for the PCV outlet valve. Which should be on the right hand side bank of the engine regardless of whether direct or port injection
@@AJS86 Yes, I pulled mine out. Not blocked yet (only 112000 k's). The holes sure are small though. I thought he was saying that this mod was only for direct injection motors.
@@scoldedcat it'll help having the holes a little more open either way. However it you will likely get more oil blow by & junk into the plenum and intake without a catch can. Obviously the PCV sends oil blow by into the engine to be burnt for emissions but it just makes a mess inside the plenum
I'm not sure on those. I discussed in this video that in 2013 they changed the design to the valve to fix the problem. I believe they started using plastic valves which I do not know how to take out.

The updated valve cover gasket actually restricts air flow below the PVC valve. I don't believe this mod is needed after that update.

Yes 2011 would have this issue as well.

Thanks , i just done mine , holden ve 3.0
The PCV Valve should be a check valve?
Hi Mister Manage.
Is this mod is for port injection or direct injection motors ? or both ?
Do the port injection motors gum up on the RH side due to small PCV, as well ?
I go over that in the video.
Sorry bro I have a question what’s re expefic name of that valve? And that’s the one for 2014 Camaro rs v6
I got 2006 cts and it burn oil like crazy It has 60 k on the engine. I did some research and did pcv bigger holes. Do you think it will help with my oil consumption ? Do I need PCV Oil Catch Can?

That will cause you to have a bad gasket and have a oil leak which leads to oil consumption. Hope that helps.
Do you recommend doing this for a v8?
As far as I know, the V8 doesn't have this issue nor do we have the same valve.
I wish I knew this shit when I got my car now I’m in for a new timing chain
Yeah that sucks man. Is it a 2010 or 11?
Same gd thing happened to me at 130K this past April. I have a 2011 LS. I feel your pain.
My 2013 camaro oil keeps burning n making my car run hot do I need a pcv valve?
my motors spitting oil out looks like it’s from the front of the engine. the car only had 91k miles on it do you think this is why?
Pull it out and check it. It is a possibility. If its clogged, then its possible pressure was not able to get out and cause it to leak or blow the seal. But it could also be a million other things. If you have oil coming from the front, it can be the timing chain cover. I don't see your car so I'm not sure. I'm also NOT A MECHANIC. So take this advice as you will.
Your link says it does not fit the 2013. Do u know if this is true
I explain that in the video. They changed the pcv valve in 2013 after they realized the issues.
Is the valve supposed to be 1 way?
It flows one way but it is not a one way check valve.
It flows one way but it is not a one way check valve.
Is this an issue on a 2014 LS? Would this be applicable?
They fixed it in late 2013. So you should have a plastic one which is bigger. Dont be afraid to check it out.
Can I do that to my 09 Cadillac CTS ?
If you have the same motor, yes. But it depends on what your PCV system looks like.
do i need to do this to a 2014 v6?
The problem was corrected by that year, as said in the video.
do they sale coil covers for the camaro?
If you mean coil overs, Yes.
What if ya dont have 7/64 drill bit?
@@great4ever845 Buy one. $3.99 drill bit is better than a new engine or timing chain repair.
im gonna go ahead and guess this voids the warranty? if you buy brand new with one of these V6s
I don't think so. They won't know you did this. What are they gana do, measure the holes?
That is a BFO strut brace!
Bc of that shit I’m pretty sure that why my timing chain stretch. The engine has to breath so make bigger holes like he said and a catch can. Saved yourself 2000$ do this 😑, that would of been spent for some Apex rims and tires 😵
I did this on my VE SV6 Commodore several years ago.
I have 310,000km on the car now.
I sometimes forget to empty my catch can 😂

I cant get mine out any help its stuck ??
Use pliers
I tried that, it wasn't moving at all
Maybe vice grips. I know its tough but just have to keep trying.
