Tech Tip Tuesday: Oil Catch can on a 1200hp LS. How we set it up! 

Next tech tip could be about proper mounting for external fuel pumps, above, or below a sump, line sizing, fuel pump size etc.

Thanks for the information, I have a built 6.0 turbo and under quite hard acceleration and de acceleration blows a cloud of smoke it mosquitoes for miles, lol, it has a none vented catch but plumbed back into the intake. Thanks ever so much.

Another great video, this needs to be pushed more in the industry, there is so much misinformation surrounding catch cans.

Late to the game, but thank you so much! I have been scratching my head looking at LS oil catch can plumbing diagrams thinking how crazy it is that there are so many ways, and wondering which was best. In my head I am thinking that is has to be easier than that. This video, makes it simple and easy. Thank you again.

Thanks for answering my question. My build should net around 1200whp. I’ll keep my -10an catch can setup!

Thanks for explaining that it really cleared a lot of things up for me I really appreciate it.

I would like to see how catch cans and air pumps relate and how the set up is keep up the good work Doug

We put a ball valve with a short section of 3/8 inch hose on the bottom of the catch can to drain it. With 27 lb of boost it gets no oil out of the catch can just nearly pure ethanol. Catch can is mounted out front on the car where it gets cold air so the alcohol distills out of the vapor.

Super happy to see content on a 🐐 If you ever wanted to sell that turbo kit I’m sure a ton of US would buy them. I’m one for sure.

Love my catch cam from your guys awesome product 💪

On my 68 mustang fuel injected 438windsor high compression e85 motor street strip car i run exact set up, except i use a Moroso baffled breather with internal foam seal in each breather n breather has hose on each one and that hose runs to breather catch can tank. Car makes around 520wheel through a big stalled th400 and will probably run high 9's all motor. Weighs 3k lbs and drives like a new Cadillac on street, but launches like a drag car. Exactly what i wanted. A car that i can drive anywhere anytime and drive to track and rip off some high 9's and drive home. Car is stupid fast from a dig and even teslas have no chance except the Plaid...lol

Dont forget to have your vent lines at the FRONT of the valvecover and not the rear ! .. When you are pulling 2g of the line the back of the valvecover fills up

Doug is there any way you could make a short video covering the rear suspension setup on your Nova? I know you run Caltracs but would like to know more about your setup. Thanks

How about a spark comparison with a distributer vs coil on plug. Detailed info on why one is better than the other.

Ordered mine today

Pros and cons ... About creating negative crankcase pressure? How low is to low (too much scavenger/vacuum pump)?

Thumbs up and new subscriber for just the boxers (good tech video, too).

Yea. I put it back into the intake even though I have an ITB set up. I hate the smell and mine is a road car

Great video. Thank you.

Options for mounting brackets would be nice.

i have been thinking about upgrading my PCV on my turbo LS. i am sold on your catch can and rocker covers. What master is Andy running on the brakes? i want to do a booster delete.

I currently have a standard catch can setup running off the PCV system on my 416 stroker ls3 could I just add this additional breathers on the valve covers and a separate catch can for less crankcase pressure?

What about the crank pcv shouldnt that be vented to a can or vaccum to intake to help oil draining on the turbo?

Can you please make a manual brake setup for 04-06 GTOs. What manual brake setup is on that car and where can I buy it?

is it true that this breather style setup generate a nasty in cabin smell specially under boost?- if yes is there a way around it, such as the exhaust scavenging setup?

Thank you so much!

How to prevent condensation water in the breather can? Just drain it often during rainy season?

At what power level would you add a vacuum system to the crankcase?🕶

On a 1971 Oldsmobile 350 engine if I run one of these ported to each valve cover do I need to have a pcv valve?

Possibly a dumb question, but how do you handle the PVC port near the throttle body? Typical PCV hose goes from valve cover to the intake. If you just run a can from the valve cover, are you just left with an open fitting at the intake?

Great tip👍👍🇨🇱

I got a question buddy so my LS engine under power is spitting oil almost every pass into the catch can how can I prevent this ?

Can you use stock LS valve cover with an fittings on both sides ?

I have a catch can with a -10 going to each valve cover on my son's naturally aspirated 5.3 and it keeps pushing the knock sensor plugs out so I'm assuming it's too much crankcase pressure but everything I've read says it should be vented plenty for a 300 hp engine 🤷🏼‍♂️

On gen V engines 3rd pcv line going to intake manifold. Should I add catch can to it?

Hi, what about the genuine PCV, did you remove that or blank it, please? Thanks.

Great product 👍 Mine is awesome 👌

What size dose a methanol motor like Garrett is using in Toast the Camaro need.

So, then an actual PCV valve is pointless then, correct? I have a dual port VTA setup like this and the OEM PCV valve is still present. LMK. Thanks. Great vid.

You don't need to any vacum to the intake while out of boost?

what would you recommend for a 99 silverado stock

Will this work for single turbo set up ??

Condensation in my catch can. Can this be normal? Thanks!

Great tutorial! i have a c7 lt1 can i use a vent catch can on it as you demonstrated? Thank you

How you deal with the catch can smell?

what about the M18 battery setup for a fuelpump :)

How to nitrous on a dead head fuel 4.6?

Doug. We’ve got a bbc only making less than 600 hp. We are pretty new to drag racing. Only a couple years in. So we’ve got an N/A bbc 468, on a Holley 850 E85 set up. Cast heads, electric water pump, fuel, fans. Nothing too fancy. I just changed our venting this last winter. I went to a breather on the valve covers, previously had a rubber hose down to the collector. But want to use those for bungs for O2 sensors. Should I do away with vents on valve covers and go to a catch can, or go back to collectors with rubber hoses from valve cover? Just wanting to protect her every way possible. Thanks for the content. I’m amazed at how much I don’t know by watching this kind of stuff. Not that I am a smart guy, but I’ve known my way around an engine from a young age. Shade tree mechanic at best!

What about a stock application like a 2017 Tacoma 6 cylinder direct injected ?? Lots of common stuff seems to focus on just separating the oil ?

Does it matter what hose goes to what inlet? Is there a dirty side or clean side?

Catch can? For decades I have used a 5litre oil bottle with two 3/4" pipes from the engine to the catch can. Half a dozen 1/8" holes in the top to vent the pressure. This on various n/a race engines. I do NOT get any oil in the can, if you do you do not have an engine. In road racing you need at least a 3 litre catch can though IF you are getting more than 10% of that your engine is junk or breathers not venting the engine. Most engines will vent to the top naturally. But with bad oiling and pan they sometime pressurise the engine and not allow it to actually breathe the engine. So look hard at your drain backs, lower the oil level in a wet sump to fix the windage which in turn improves oiling and power. On some engines a breather, 3/4", between the side of the pan to the rocker cover helps. Left side of the engine is best. All of these mega power engines should be properly dry sumped. Wet sump is for the towcar. And if you are still building pressure fix the ring seal!! It seems these hairdryer engines all fume like blazes,,, maybe do something with the ring seal. Watch the Casey Jones cloud out of the bootlid as they leave.

What would you recommend for helping out the oil smell with venting esp with e85? I have no pcv and the car reeks at stop lights. Thanks

Tech tip next week.... how to clean intake that has been oiled from pcv without dismantling

Can't find that pass through bulkhead fitting for an air to water. Whats it called?

Tech tip: steam vents!!!

Is there any need to vent the Valley cover ??

What would cause the catch can too smoke under boost?

How is the oil in catch can contaminated?? 🤔

That was the most non informative video ever. Having it actually setup and plumbed and speaking on it that was is alot more helpful.

HOW ABOUT A TECH TIP ON CHARGING SYSTEM

Can you talk about coolant catch cans next?

Thats called a Breath Not a crankplate intake catchcan that will cause the oilpan too leak the breather Wont but dosent really catch much oil

That's A damn breather can not a catch can dude.
