Best thing for those push to connect fittings - boil a pan of hot water, dunk the hose end in the water for a minute or so, then slam them on the fittings. Works well and leaves no residue that can cause the hose to blow off later.

[@intheshoptv]

I used to do that. I find that the BEST way is to use new hose. But a slight film of silicone grease never hurt

Hi thanks for your advice, i am considering mounting one of those on my pick up, but I have noticed that on my crank case I have 2 pipes that release pressure/fumes. 1 goes from crankcase inside the air admissions manifold(between filter and throttle body)...the second pipe goes from the crankcase inside the inlet (between throttle body, map sensor) my doubts is, where should I place the oil catch canister?or should I place 2? both gets dirty with oil😅

[@intheshoptv]

@@powergym1984 I dont know what kind if engine you have, but for a vented catch can application, you’d run a line off each (assuming v8) valve cover to the catch can. Then you’d cap off the inlets to the throttle body and intake manifold.

[@BillyP-49Chevy]

Glad I stumbled upon this channel my friend. I'm building a 6.0 in a 49 Chevy. Of course the same intake as yourself. I could not get injectors in the intake. Long story short I had to ream the holes out in order to get my Holly injectors to fit the intake. As for the catch can I'm glad I saw that video as well. I will be running boost and it's good to know I need to go with the double inlets on the catch can. It's my first time ever building LS motors so a lot of this stuff is new to me. Great great explanations on your videos. Thank you.

[@intheshoptv]

Hey! Thank you! So I just went through making the injectors fit properly. There are several different o-rings. You need to find the ones that fit your intake/rails. Here’s the intake video about it: Fabricated Sheet Metal Intake Manifolds - Should YOU Get One? kzbin.info/www/bejne/oaCamYx4f9l-h9k

@@ashleykolbuss6932 thanks man. I did another catch can video not long ago too.

[@kevinoneill41]

My reason for the vented can is simple. It's Clean cold air fuel ratio. Keeping my cold air intake as clean as possible and polished for air movement also offers the best and cleanest combustion for the best HP and MPG and the most pollution-free exhaust per MPG

[@intheshoptv]

I’m with you - the cleaner the air, (and intake) the better👍

[@DWGarageProject]

I plan to run a dual sealed catch can setup from Racetronix. One will be inline from a valve cover to the air filter base, and the other will be inline from another valve cover to the throttle base PCV port. The twist on my setup will be this adjustable billet PCV valve from Wagner Performance on the outlet of the 2nd catch can, which will keep it cleaner than it being on the valve cover passing the contamination to the catch can. Im sure some people will think what they will about my first catch can being plumbed to the air cleaner base, but the factory engineers were clever! There is more negative pressure between the air cleaner and the throttle, where the engine bay will be at atmosphere, or even pressurized slightly. Under load, your crank case will fare better if the breather line was being scavenged over being vented.

[@intheshoptv]

Sounds inventive and elaborate. I like it

[@sloeryd]

DW I totally agree with you.

[@sloeryd]

@@intheshoptvnegative pressure in the crankcase is the best scenario. That is why the sealed can is better. The crankcase is always pressurized in order for the vented system to work. This is a less than ideal scenario.

[@truthseeker9026]

Okay, so I have a questions. I’ve watched many oil catch cans now. I’ve noticed that most of, if not nearly all the videos, run the oil catch cans from the valve cover/s. That’s fine but what about the main pcv that exists off of the block instead… I’ve seen very few run the can off of that. Ig my question is many; is running the oil catch cans off the valve cover enough? Or is it better to put the can to use off of the “block” pcv? Is it possible to run a duel setup that feeds both systems? The reason is ask is because if it’s just off of the valve covers, that usually just recirculates back-before the throttle body. The pcv off the block, runs back into the manifold itself. So if you doing it just off the valve covers; aren’t you missing that vapor being sent to the manifold? This is assuming both are still needed. Now I’m researching this for maintenance purposes on my daily, which is a K-series Honda. So Ik you said that’s an LS but I’m still assuming it still has a block pcv too. So I’m confused ig. Not to mention. If it’s from the block, can it be vented. Would that just be a “leak”? Or since “air” from the block goes back into the manifold, would replacing it be fresh air be the same? I’m tempted to just buy two catch cans. One for valve cover, one for block. Run both vented, I’m curious as to if that’s too much and will make it a “air leak” to due unmetered fresh air-after the maf. Thus triggering a code. If so, go sealed for the block; keeping vented for the valve cover. I am curious because I have not seen that done. I’ve looked all over…can’t find anything like that. So idk if that will work, both vented. What does the internet think?

[@intheshoptv]

Like me you suffer from over thinker’s disease lol… pcv or “ positive crankcase ventilation” is pcv no matter where you take it from. Taking it from two different locations is pointless. Yes, if you take pcv from the valve covers and vent to atmosphere, you are missing it being recirculated back into the manifold… but thats kind of the whole point. You don’t HAVE to send it back through to be reburnt. In fact, if you run high horsepower or boost ect, you dont WANT to send it back to the manifold. On a street car, its really just a matter of preference.

[@EvzenKovar-i5p]

My Toyota PCV is slung low on the block and slurps engine oil. I ran a sealed unit in the line last spring. No engine lights(I’m sure it would throw a vacuum code if it wasn’t sealed). It’s been catching a mix of oil and water. I’m sure it’s not catching everything, but otherwise the air intake is a disaster and that oil vapor mixes with the EGR gases at the top of the manifold and forms a sludge that eventually blocks the EGR ports. So I’ll take what I can get. Make sure you run a high quality hose, mine was like $10/foot from Napa, otherwise it’ll likely collapse with the heat and vacuum it’s under. I’ve seen a lot of videos where the creator has that happen.

[@SlowpokePNW]

[@AdventuresofAwesomeJoe]

My boxer engine has three vacuum lines: two for each valve cover that go to the intake before throttle body and the third is from the crankcase to the PVC valve intake manifold. The crankcase to manifold has all of the oil residue, but the valve cover tubes are clean with 180k miles. So, I think I only need the catch can for the crankcase, correct?

[@intheshoptv]

If you want to keep the same recirculating configuration (not venting to atmosphere), then yes, thats exactly correct!

[@ijmodified]

You're right and on boxer engines like Porsche you shouldn't ever need a catch cans between heads and intake because they have scavenger pumps in the heads forcing the oil out of the heads to the crank case if you ever get oil in those line then the pumps in the heads are bad

The only thing I have thought of is maybe there should be some sort of relief between the PCV and the vacuum line in case it freezes up in cold weather because 1/2 the stuff in the can will be water and over pressuring the crankcase would be bad news, especially with plastic valve covers, just a thought

[@jets8991]

Does a catch can hold vacuum? Like could I run my brake booster AND my pcv valve off of a catch can rather than just the pcv? Would a sealed can be better for my application?Trying to do a vacuum pump delete on my silverado. And not trying to crimp off my pcv valve

[@intheshoptv]

Think of it this way, 1- a sealed catch can is nothing more than a container in line with your PCV plumbing. It can NOT be ventilated if it’s in-between your PCV plumbing because it would introduce a vacuum leak. 2- a vented catch can acts as your crankcase vent, without any lines returning to the intake. Think: breathers on valve covers during the carburetor days. Same thing, only with a can to catch any vapors containing oil/particulates Hope that paints a more clear picture

[@oilburner8548]

[@intheshoptv]

@@oilburner8548 glad it was helpful. Thank you for watching!

[@josephcharnowski5578]

Does it matter to have that catch can mounted that close to your air intake? Won't your air intake suck up that Steam and Vapors? also, I'm guessing I would need the vented type? because I'm running about 850whp currently.

[@intheshoptv]

I love getting great questions like this! No, in my case, that intake tube’s filter will poke through the inner fender and not be in the engine bay anyway. Although, even if it was, the can’s “smoke” wouldn’t matter, as all the oil has already been separated. In a sealed/non vented application, its supposed to return to the intake anyway (granted not through the throttle body) but its not a big concern. In your case, especially if you’re running boost or a power adder, yes, you’d benefit from a vented system. Thanks for watching and for the great comment!

So let me explain so I understand it myself. So non-vented would be coming from the vc to the IN port and the OUT port goes to the intake manifold. Now vented you just reverse your hoses at the catch can? Is this right?

[@intheshoptv]

Depends on the can you’re using. With a can like the motion raceworks that’s designed to be vented to atmosphere, You simply run a line off each VC to the dual inputs of the can. In a sealed can, you would run the output of the can to the intake, correct.

[@jasoncollins9081]

​@@intheshoptv Hmm? Both VC? My system from the factory is not set up with a PVC on both VC. I have a 2013 Chevrolet Silverado 1500 LTZ. My system have the PVC only on the left VC which connects to the top of the intake manifold. I know this cause I had to upgrade the valve cover to the updated design my GM. The oil catch can is like the first one in your video the Evil Energy. I think my options are very limited here with my particular setup from the factory. Thanks again!

[@Jonny9547]

If I wanted to block off the port on the manifold and my intake on the car and run the catch can inline between the 2 valve covers on my car does it need to be vented or can I do that with a seal can as well? For reference v6 NA motor making maybe 320whp

Some food for thought, venting to air keeps the crankcase at atmosphere. Venting back to the intake would keep the crankcase in a slight vacuum(in my mind is better). Like you i dont like the idea of oily air going back into the intake, so why not connect to your ehaust?

[@intheshoptv]

I was actually discussing doing that with someone on the LS forums a few weeks ago.

[@luke-e1t]

100% ... with that set up, long thin lines with no vacuum, id guess a higher crank case pressure than the original set up. Another way is use a 12v secondary air pump (smog pump) pulling from the catch can

[@79_Trucker]

Mike that would be called “blow by” thanks for the rundown.

Oil vapers have been going back into our engines for many years, we didn't see it in manifolds because it went in before the carb, in the air filter, and then was "washed" away by the air/fuel mixture.

No engine blow by. Think of it as sewage. Going back to mixing the filtered cold air with sticky sewage then polluting the air-fuel ratio giving a much poorer combustion losing HP and MPG. With each combustion revolution the cold air intake reduces in size slowly choking off the air to the engine. Sticking to the backs valves and highly machined and balanced turbo parts and injectors then turning into very hard-to-clean carbon again closing down and choking the air to combustion chambers. As well as reducing the quality of the best and cleanest combustion ie. pollution. That gets worse with each combustion. That is just poor engineering and quality controle. The Vented catch can is the best with the least all around trade-offs.
