That you for that tip. No one talks about this! I wish I knew this a year ago! Had my engine out & replaced all the gaskets & less than 100 miles she’s leaking. Running dual breathers & no pcv. Now I know why! Thanks again!
Cool tip. I'm just running a tube over to a can with a flapper. My truck won't run right with just a breather. It's a TBI unit. It gets mad if it can't pull a vacuum. I put a very small notch in the flapper so air can still pull from one side to the other with the PCV. I tried running with just to catch can. But I pull trailers and it would fill the catch can up in just a hundred miles. It seems to like the PCV on one side and flapper catch can on the other. It's not super overbuilt forged crank forged rods hypereutectic Pistons. 388 SBC with 454 TBI cam is 218 212 @50 .51 life on 112° lobe separation. Or 114 I can't remember. I took the swirl out of the swirl Port heads. Smooth and polish the combustion chamber. I still have to run 93 gas I accidentally got 87 once and broke a piston ring that one cylinder is border 80 over. I have no clue what my horsepower is I built it mainly for torque. My truck and trailer with skid steer. Weighs 18,000 lb give or take depending on the job. She sits at 3300 RPM in 4th gear at 65. I'm scared to use 5th gear pulling that heavy. I guess my only complaint is she will not pull below 2000 RPM. It actually seems to have less power below 2500 then when it was a little baby 350. But anything above 2500 and she pulls like a diesel. I can tell you I snapped The hub out of a brand new clutch for a 454. My truck's kind of a mutt. The block is out of a 98 Chevy. transmission from a 93 1 ton 454 and TBI unit. Rear end is from a 2006 F350. Drive shaft from a 95 Chevy 2500 van. Transfer case I don't even remember where it came from. Np205 divorced. Front diff CV axles and hub assemblies. From a 93 k1500 Diesel suburban. Front drive shaft from a 91 Ford IDI. Custom rear leaf springs from rays champion springs. Yep she's the poor boy toe pig. I've had a lot of other trucks. But this one refuses to leave my side. I've had her for 11 years now. And I'm debating on whether or not to do the solid axle swap for the front. But I have to rebuild the front end every year. And it's coming up she's all wore out. My dad's F-250 rides like s*** but we've never had to rebuild the front end and he's off-road just as much as me. So may be sas time.
I just remove the pcv... put in a straight fitting, run a 1/2 inch hose from there to a catch can... then another 1/2 inch hose from the valve cover breathers to another catch can.. now the motor has exit ports to breathe = less restriction on the crank = more hp ...
I have about 300 miles on a brand new 350 crate motor.And it's using about a quart of oil a week.It's not leaking anywhere I swear it's the PVC valve is sucking it out of the engine .There is no smoke coming out of the tailpipe.Or is it just the ring having broken in yet.
@@Watchout1010 yeah didn't have a valve cover breather on one side and had bad valve seals and was blowing gaskets. To much pressure and the oil was running down my valve stems and causing the oil to cover my spark plugs. So I had oil on my plug threads....
Thanks for the tip- My breathers have low mileage, but they're around 20 years old- Should they be replaced periodically, or is there a way I can test their effectiveness?
What about the aftermarket push in pcv valves that look just like this air breather push in? Can you do a video on factory, vs after market pcv valves?
A breather thats meant to only be a breather has a bunch of holes on the underside of it if it doesnt its an actual PCV valve that looks like a push in breather. but youd be hooking that up to manifold vacuum because thats what PCV valves are for. breathers take in fresh air only, whether its an aftermaket one with a 5/8ths tube on it to hook up to your air cleaner to get fresh air or looks like the one in the video where its just getting air and has no tube because maybe your air cleaner doesnt have that provision for a 5/8ths tube hookup from the breather PCV valves vent the engine after that air is taken in. there should NOT be a bunch of holes in the bottom of those types of aftermarket breathers and it will look like this breather with a 3/8s tube on the top of it, not a 5/8s tube.
pcv valve location is on passenger side?? I have mine in front driver side valve cover going into front of Edelbrock carb ... 454 big block out of 86 pace arrrow motor home into a 1971 monte carlo
It doesn't matter which side your PCV valve is as long as you run some type PCV system just more convenient to have mine on the passenger side that way I can get to my oil fill easily
Technically your PCV valve pulls the crank case pressure out the valve cover breather let's air in so the PCV can do its job without a PCV valve yes you will blow gaskets and seals you must run a PCV valve and a valve cover breather
What about the preheater hose? Can you run that with those types of air filters. I’s there any way to reroute it back into the intake system or do you just have to get rid of that
You won't be able to reuse your preheater just remove it if it's the one you're talking about that goes down to the exhaust manifold it's just there to pull warm air up to the air cleaner in the winter time to help with cold start and running
No you need to run a PCV valve. Along with a crankcase breather unless you are running a big high horsepower and high compression engine turning a lot of RPMs then you may want to run a catch can it just depends on the engine and what your PVC system can handle and what the car is designed to do ie street race drag race pro touring xcetera
On newer engines you replace the hose that goes to your intake tube with a breather filter correct? Or is it the side that a hose goes from intake manifold to pcv?
So could get one of these breathers instead of getting a tube from the valve cover to the tube hole on the air filter? It’s hard to fit the tube by the carb so wondering if it’s easier to get one of these instead for a tube for the breather to the air filter
LOL yeah thats what i got on my 302.....just baffled valve covers and i have two breathers. gotta change the oil and run it. proably wont have an issue. i just dont think its a good idea to run non baffled valve covers unless you have a very specific reason to do so..
That you for that tip.
No one talks about this!

RIP brother you will be missed
So Helpful as I do some repairs on my late father’s 69 Chevelle Malibu. Thank you!🙏🏻
Good advise ! that's how i always ran my breathes on my race engines..Nice video well made !
Thanks for the knowledge. I knew it was wisdom when I heard Black Magic Woman in the background 🎸🎹🎙🎶
That's exactly the info I was looking for! Thank you for taking the time to make this!
Thanks for this. Was wondering what this was on my valve covers
Thanks Chris that is exactly what I needed explained!
simple but it work's thanks for the trick will try it out
Thank u 18 rn building my C10 u help me alot
Great old school tip bud...

Aluminium baffled valve covers on the net-no baffle will always leak or use oil..
Thanks, just what I needed.
Marshall Malone Your welcome happy to pass along my tips and tricks after 35 + years of building cars
Just what I needed! Have a new sub 👍🏻
Thank you Sir👍

Do you have a picture of how this looks?
@@vinihidalgo96 yes

Thanks man !! Awesome advice.
Good background music
Thanks help I just did that and put pvc valve pass back valve cover
Thank you for video ✌️
Its the little things. great tip
hell yeah Thanks
This was a life saver. Could this be the reason my plug threads are getting oil on them??
Threads with oil? Plugs are sealed into the cylinder with a taper or a gasket?valvecover cover the plug holes,gaskets,seals..
@@Watchout1010 yeah didn't have a valve cover breather on one side and had bad valve seals and was blowing gaskets. To much pressure and the oil was running down my valve stems and causing the oil to cover my spark plugs. So I had oil on my plug threads....

PCV valves vent the engine after that air is taken in. there should NOT be a bunch of holes in the bottom of those types of aftermarket breathers and it will look like this breather with a 3/8s tube on the top of it, not a 5/8s tube.
Where did u get that grommet?
Thanks in advance
Buy them at just about any auto parts store
Thanks! Great trick!
thanks good help.
Cool idea boss
pcv valve location is on passenger side?? I have mine in front driver side valve cover going into front of Edelbrock carb ... 454 big block out of 86 pace arrrow motor home into a 1971 monte carlo
It doesn't matter which side your PCV valve is as long as you run some type PCV system just more convenient to have mine on the passenger side that way I can get to my oil fill easily
I thought positive pressure blows out gaskets and the intake is sucking it out to lessen it?
Technically your PCV valve pulls the crank case pressure out the valve cover breather let's air
in so the PCV can do its job without a PCV valve yes you will blow gaskets and seals you must run a PCV valve and a valve cover breather
Does the breather tube cover the hole tho? Looks like it would
What about the preheater hose? Can you run that with those types of air filters. I’s there any way to reroute it back into the intake system or do you just have to get rid of that
You won't be able to reuse your preheater just remove it if it's the one you're talking about that goes down to the exhaust manifold it's just there to pull warm air up to the air cleaner in the winter time to help with cold start and running
Thanks so much !
Is a baffled breather filter enough to prevent leaking? I'm trying to decide if I need that or a catch can.
No you need to run a PCV valve. Along with a crankcase breather unless you are running a big high horsepower and high compression engine turning a lot of RPMs then you may want to run a catch can it just depends on the engine and what your PVC system can handle and what the car is designed to do ie street race drag race pro touring xcetera
On newer engines you replace the hose that goes to your intake tube with a breather filter correct? Or is it the side that a hose goes from intake manifold to pcv?
You definitely want to run a PCV valve. And then run a crankcase filter on the opposite about cover
where'd you find that grommet cant even find it at napa
You're just dealing with idiots LOL you can find them at most part stores look in there aftermarket breather section or go online to Jegs or Summit
What if I was to drill 1/8" holes around the bottom side of the grommet? Maybe five holes?
That can work also and if you need to put oil in just pop your grommet out put back in after your oil change
So could get one of these breathers instead of getting a tube from the valve cover to the tube hole on the air filter? It’s hard to fit the tube by the carb so wondering if it’s easier to get one of these instead for a tube for the breather to the air filter
Put oil on tube
Doing this mod tomorrow 02 1500 GMC serria 4.3 vortec 403000 miles
Are you running stock valve covers?? And yes it could be rings haven't broken in yet What oil are you using??
Can't find the solid breather grommet. Where did you get yours?
Did the covers come with the holes or did you put them in?
No the valve covers already had the holes in them for the breathers
Still chingo de pollo va salir that's to big probably won't work
👏
Thx
Moroso Breather Grommets with Integral Baffles 68775
Ya know what I found that works better is a good baffled valvecover,tried all that and more-baffles baffle people
LOL yeah thats what i got on my 302.....just baffled valve covers and i have two breathers. gotta change the oil and run it. proably wont have an issue. i just dont think its a good idea to run non baffled valve covers unless you have a very specific reason to do so..
Wrong again! All you "experts" use "worn out" engines with too much blow by!
Genius!
