Excellent. What Ive learned here has expanded my knowledge. I need to demand a raise now that I’m bringing more to the table. I’m putting you down as a contact on my resume.

Header evac systems definitely work! On my Olds 455 street/strip combo the system, at 1100rpm idle, pulls so much vacuum that I can pull a valve cover breather connected to just one side via 5/8 hose will stick to your hand on the plug into grommet breather side and you haven't to wiggle and turn sideways said breather to get it lose from the palm of your hand. I never measured the actual vacuum but for sure it's present and it's more than just a little bit. Yes these systems will put smoke out the exhaust pipes, depending on how well the valve cover is baffled, so that is one downside. As far as helping the rings seat on a 13:1 compression 620hp n/a motor...? Let's just say YES...ring seal is considerably better with that low pressure/vacuum in the crankcase!

I know a lot of the old school tricks, but I actually haven't seen this one before! Definitely makes sense.

I'm a mechanic myself. Both Diesel and Gasoline engines. I wonder why this man doesn't get more views and subscribers. I live in Iran, and I paid dearly to learn all these stuff. Going through inefficient classes, working for bullies half my size, and at the end, getting tired and teaching myself. I think people just don't appreciate a top-notch knowledge when it's given for free. I studied Clinical Psychology and one of our professors always said: Never consult people for free because if they don't pay you they won't appreciate your help...

A lot going on in there. The carburetor's carbin', the crankshaft's crankin', and the pistons .... well, their workin' too! Great vid and very informative as well. Thanks!!!

Great breakdown 👍🏾👍🏾👍🏾

Not only does it give that little bit extra power, I bet it helps keep it all clean inside too.

Loved this bro!!

Good stuff 👍

I have that Mr Gasket kit, never been used, bought it from Giant Auto about 25-30 years ago

Will definetely do it this way oned day Most efficient way to vent the crankcase! Nitro loves windage to cushion the harmonics haha. They work in a world of their own.

The old school v8's would have a PCV valve on one valve cover going to the intake manifold, and another vent on the other valve cover with a hose going into the air filter housing. The air filter housing had a foam filter on the hose inlet to prevent oil from gunking the carburetor. Thus both valve covers were vented. I preferred to simply run valve cover breathers on both sides venting to fresh air, however if your windows were open you would end up catching a fair bit of exhaust odor coming from the engine compartment.

"Recipicating...Recipenticate...reciprocate...Moving up and Down!"😂😂🤣 Love the info. I really had no idea about this. 🤘

Ive been looking all over for one of these because im trying to water proof my 350 in my truck without useing a pcv or catch can and have the snorkel but just breathers on top of valve covers yeah I kno im not building a submarine but want the best i can get and because its a 73 its emmision exempt lol awesome video

I use it in all my mud bog trucks

You could run a pcv on one side and a crankcase evacuation on the other side.

Ok, so which of these two systems is the better option allows you to gain better horsepower?

Hello o just did it on my 327 and the question is do i need a breather on the engine ? Like the old intakes? I have the airgap and now Both sides of the valve covers go to the headders so i dont know if i got it right thanks

what’s your take on the classic old “302 500 hp block split”? what’s some things you’re going to do to prevent that from happening on that engine in the video? i’m trying to build up a 302 for my truck and the block split issue is the one thing that’s concerning me about it

My son's early 65 mustang had a draft tube that comes off the back of the intake and drops down past the exhaust and just dumps into open air. Ford could have added the nipple to the right bank exhaust pipe and made this system easily.

Also supercharged engines need this? If yes is it the same method?

Have you seen BoogieTech channel? He talks about these and proves the power adding on a dyno.

You sound like norm McDonald trying to imitate the vice grip garage

How much horse power does it increase

But can you make a PCV out of PVC? Also is this how they made the oil slick getaway devise in the James Bond movie cars?

Let's say you have a centrifugal supercharged setup. What if I setup an oil catch can coming off the intake manifold going into the intake pipe of the supercharger. That way ur using the supercharger to pull crankcase pressure out

Hey you’re vice grip garage guy but with a berd

think I'll just stick with a PCV system

Ok, that is what the car wants you to believe, but in fact, that is a Crack pipe for the engine... Its why it finds your inputs more interesting and seemingly has more power/responds better with it... Just ask any cra(n)ck-case and you will get a honest answer... Machinery likes to hide its vices, but not junkies... :P p.s. all jokes aside, that is a brilliant system, but quite severely incompatible with modern cars... All the nonsense added onto the exhaust that does not like oil and shit like that... The catalyst, the dpf in case of a diesel and such systems dont really fare too well with oil contamination... I dont hate those, dont get me wrong, i love the catalyst and dpf on diesels, for they really do make the car much less offensive to the nose, but they force you to place this weld pipe much further down the exhaust, after both the turbo(90%of modern cars) and the filters like the cat and dpf, which can place it over a full meter(over 3 feet) away, making you rely on much longer hoses to connect to the covers... And longer hose reduces pressure by itself, or negative pressure, rendering the system less efficient(even less so, as its much further away from the manifold, where the venturi effect would be the strongest) and at risk of catching fire if not well assembled to make sure your hose cant touch the hot exhaust in the first 3 feet after the manifold... Sure, there are solutions to it, but this is really a cherry atop the cake for essentially pre 1970`s or even pre `60`s cars with their much less complicated systems... Which i know the channel is all about, but i cant help myself from lamenting the apparent flaws of complexity with modern cars... By modern, i mean from 1990s to 2012... 2012 and after arent cars anymore, its just overpriced junk designed to fall apart in less than a decade... Looks amazing and drives amazing, but its junk...

Thats fine and all but why would you have a tv and pictures and stuff inside your house and not more engine? weird

Super high compression motors at full throttle would blow oil out on the track. This was developed to stop that. Some one is always making up crap to explain something.

Can we communicate on discord or email, quite an interesting subject
