This channel is so under rated, you guys do so much for the racing community. I look forward to the day when Motion Raceworks is as big as Summit or Jegs.

These tech tips are dynamite for us guys that are getting back into the performance scene, thanks for the clear explanations.

I have 0% of needing to know this. But, I enjoy learning and hearing Doug talk. 🤣😂🤣😂

When we first started to run Methanol through the big block in our drag car, our crank case ventilation was inadequate. We found out that it can be very dangerous. Driver side valve cover (cast aluminum) exploded sending pieces into the fender and fiberglass hood. Could have been a bad deal had someone been leaning over the fender with the hood up. By the next weekend we had a crank case pump never had a problem after that. This was well before Motion Raceworks came along. But lesson learned is that Doug is right and that crank case ventilation is very important and to make sure you have a good system in place.

Just a couple days ago Cleetus told us to put the catch can vents toward the front of the engine because of the G force during acceleration tends to push oil out the back of the covers. You guys need to get on the same page about this stuff.

I was so interested in the this tech Tuesday and my wife says "is that the guy from guardians of the galaxy". I said who she said "kraglin" from guardians of the galaxy 2. I looked it up and compared your voice to now I can't unhear it. Great tech Tuesday. Ahmad

Vacuum pumps- how they work and how they attach. (I know that's more of a full-on racecar deal, but it would help guys tremendously)

I'm just starting out in no prep. I love how I can watch Doug's videos and then feel confident in what I'm doing. Very good way of explaining things so we can understand. Great job guys!

The air/oil film finding a way out, 100% can confirm. I have a baby 700 hp BBC 540 thats NA and had the PCV vented to the intake. Idling, around town driving nothing and not a big deal. But when giving it the go pedal, oil was pushing out the filler cap then running off the back of the engine and making a mess. I'd also get puffs of white smoke too from it being burned in the engine. First build I've done at this power level, learning as I go, and solving problems as they come up. I ordered one of these cans because the baffling and am excited. My first Motion Raceworks product. Love that you sent an email with how to setup and the video was full of great information. I didn't even think about if you're venting to the intake how it could throw more air in, mess with your AFR and need tuning to adjust the top in. Cheers!

Made one at work about 8 months and did some nice baffling in it. Man the difference in the cleanliness in the intake when I did injector change for my mass air swap. in my 96 351w powered f250 the milky yummyness and my dry filter tells me I did a good job 😁 thank you for another good video.

Can't wait to see you guys on race week 2.0!!

Many people have small oil leaks they cant figure out because they aren't letting their engines properly breathe and have bad crankcase pressure making the oil push out anywhere it can. I have a supercharged Camaro that made 753whp but I had large amounts of oil bubbling and fumes coming out of the little breathers I had for each stock LS3 valve cover. I also had oil coming out of front main seal multiple times. Found out that I needed to allow engine to breathe better by plugging up the little pcv ports on both stock heads and getting bigger breather lines on each valve cover to reduce pressure. My oil leaks were fixed after that and now that I learned that I bought 2 Motion Raceworks breathable oil catch cans with a -12an setup for my new engine.

Just installed your billet catch can and valve covers, high quality parts for sure

[cecilsabourin]

Just fantastic guy. So well explaned and understood. just purchased a catch can system for me '92 chev. 1500. this is exactly what i needed, thanks for this expert info. I, m, now, a subscriber.

[chrisobrien]

Great episode Doug. As I’m now going Turbo LS Is very good to have this type of information. Thanks m8. Support from Australia 🇦🇺

[kygator]

Well after talking to you guys last week about this exact product I guess I'll be ordering soon for my 21 camaro... 😎👍

[stevemacdaddy]

Catch can are good for ALL engines. I’ve had a Ford Performance on my 5.0 F-150 since new in 2018 and a Moroso on my wife’s 2015 Honda Civic since since 2017. There is ALWAYS oil in them when checked. My LSR engine has had a vacuum pump for 25 years and because the engine has close to zero leak down the container has only had water condensate in it.

[katemcswan]

Love the product but just wondering about volume of the tank, in Australia we have to run a 3 litre can for circuit/track applications. Do you have a bigger one? I’m having trouble with my my new LS putting about 2 litre into my can over the course of a weekend.

[jasonstrester]

What happens if you forget to empty your can? Will it damage your engine? Or just leak out the vent or blow a seal?
