Yes, all our Catch Cans come with mounting hardware, connections, and hose.  However, it was recently brought to our attention our current mounting bracket needs to be altered to fit the newer 2019+ engine bay.  We're working to get a bracket modified for these newer trucks.

I have a can!  But I know I am still coking...I just like to look at is all?

Anyone going to clean their valves manually, do a before dyno with 3 runs for a good baseline, then do your cleaning and on the same dyno document the restored power. That's an accurate way to document just what the impact is. No arguing, just facts.  

 

Here is a new Corvette at 20k miles before and after the same day:

 

This is not a marginal amount, it shows gains right from the hit and as RPM's climb, the spread increases showing ANY disruption on the valves shape, finish, and change from the original design has a negative effect on overall efficiency. This has a negative effect on fuel economy and power.  

 

This owner did this himself as well and is an Aerospace Engineer and stated when he decided to conduct this test "I will be amazed if this has lost any power"  "It feels just as strong as ever" and the after was "wow". As the loss is very gradual and the impact of cleaning is immediate this is common.  But I would like to see some members do this at 40-50-60k miles. Take pictures to document the amount of coking. I know, I share plenty, but that is a bias that is eliminated when someone does it themselves. Take before and after pictures of the valves, and the before and after dyno runs.

 

I always like to go back to the BMW tech that started after his 5 series was a year old and did dyno runs on the same local dyno every year at app. the same time and then performed a manual cleaning. Study his dyno graphs:

 

The runs start when his car is app 1 year old and is the light blue. Already a power degradation. Then the red the next year, and green the next, and then the cleaning (never do a solvent based engine running service!!) and the dyno a few weeks after as the cleaning is the dark blue. But of course this is a BMW GDI engine and they know the impact all to well.   

 

So would like to see a few do similar (not taking 4 years of course like this tech, but a before and after dyno session).  This will not convince the more stubborn skeptics,  but most will see this as it is.

 

Cheers!!!!

Any idea when it will be ready to go? Thx

Beautiful truck!  We should have this available in two weeks

Why is your catch can better than just venting it to atmosphere? Other than pollution. Not trying to knock anyone's product but it seems as though all of the coking would stop with a small in line breather on the pcv side and plug the line at the intake side. No draining and 100% effective.

There are many things that make this far superior, but lets start at the beginning of the Automobile in the early 1900's. The internal combustion engine was relatively new technology, and with so little science, all were vented as you are describing. It was simple assumption. All engines have blow-by, and this results in pressure building in the crankcase, so they simply vented. This was done for the next 60 some years as engineers knew no better. The engines improved as did the oils, and eventually reached an industry average of app 40-50,000 miles of life before the engine needed to be totally rebuilt. The wear was substantial enough we could not remove the pistons with out first cutting (machining) the wear ridge from the top of each cylinder before we could remove pistons.  And this was changing oil every 1000-1,200 miles.  Now, much has improved from them in every aspect of the engine, but in the mid 1960's, the Federal Government stepped in and mandated steps to reduce the groundwater pollution caused by the dirty oil dripping from these vents, known as "downdraft tubes". This would wash off with rain and pollute groundwater (just as they used to advise digging a hole and pouring in dirty oil to dispose of it). And they also were beginning to address air pollution as well. 

 

   So enter the PCV system as we know it today. This used the intake manifold vacuum you actually evacuate the crankcase VS venting it, and re-burning some of what it sucked in through the combustion process. BUT, something else unexpected happened. These same engines, using the same oils, now were lasting 100k plus miles and when torn down had a fraction of the wear as before the PCV system. Why was that?  It took a few years of study to determine that most internal wear to the engine was caused by the combustion by-products that are part of the blow-by.  And that by flushing and evacuating them (sucking them out), the engine oil remained far cleaner for longer and the 2400 mile oil change was adopted as well. And this has remained much the same since.

 

Now, how does this apply today? Well intake valve coking used to be an issue back then as well when carburetors were used. Not nearly the severity of today, but it was an issue and resulted in us having to do valve jobs on engines. That went away as the port fuel injection systems were adopted, and the fuel cleaned and cooled the valves. Bit with GDI no fuel touches the back sides of the intake valves so it is the worst it has ever been in the past 50 years. So, your assumption is just as back in the early 1900's. Lets just vent the crankcase and no vapors will bake onto the valves, correct? But, what happens to the contaminants that cause most of the internal wear now? Most would be left in the crankcase to accumulate and overwhelm the oils ability to protect causing greatly accelerated engine wear. You could change oil every 1000 miles again, but the cost and hassle would be no fun.  So, we need to not only retain the evacuation function, but as our Patented design of the E2-X system at app. 95% effectiveness in trapping and containing these substances (vs 15-20% average of most all other catchcan designs (ours being a true air/oil separating crankcase evacuation system, far from a "catchcan") means only scrubbed clean vapors are entering. And then, we go a few steps further. We add a secondary evacuation suction source as intake manifold vacuum is ONLY present at idle, light cruise, and deceleration, (reversion pulses caused by the cam lobe overlap spikes backwards up the intake manifold runners when accelerating or at WOT operation). So we use two sources and a series of special checkvalves to always provide evacuation suction on the crankcase, and a billet cleanside separator (not used on the 2019 and up GM Truck V8 due to design changes) to trap any oil that does enter backwards during the switching of the valves.  So we provide full time, vs part time evacuation and flushing as well as the most effective separation and containment on the market.

 

So just venting DOES prevent up to 85% of intake valve coking just as our can does (some still occurs from backfilling the intake port with burnt gasses to emulate the EGR systems function and a small amount will always get past the valve seals to lubricate the guides and stems.  BUT, your engine goes back to the wear levels and contamination levels of pre PCV system days. And your entire engine is more important than the valves alone.

 

So now, let's examine the oil contamination.  As we provide full time evacuation and flushing out of these wear and damage causing substances, your oil remains cleaner longer. Wear is reduced (by as much as 70% plus) and if you use a full synthetic, they don't wear out and break down like a conventional or a blend does. They simply become overwhelmed with contaminates until reach a "condemned" state meaning it can no longer protect as designed. But, when using our system several other benefits occur aside from intake valve coking prevention. Fuel economy improves by 8-10% on average as we eliminate most knock retard so ignition timing remains at optimum advance more often.  Oil consumption drops and power is gained as piston rings are more stable and seal better with suction present all the time in the crankcase, and oil stays cleaner far longer. This oil analysis shows this. This car is a twin turbo, so subject to more blow-by then a NA engine. Also, this build makes over 20# of boost and is driven hard. He has been testing the impact of our system on oil life and it's ability to remove these contaminants before they have a chance to settle and mix and accumulate. Note the lab techs comments. Next sample is at 20k miles with our system on. Prior to installing our system, he was above these degradation levels by 3-4k miles. 

 

 

So, I know this is long and boring, but it covers all in as understandable terms as possible. Well worth several reads to absorb and understand. The PCV system and its functions are critical to far more than pollution control, and we enhance the function of the standard PCV system substantially while still meeting emissions requirements (except in the planet Kalifornia as we have not pursued CARB certification there yet).

I don’t drive my truck often. 2-3 days a week max. This is over a few months. I’m floored at how much oil I pulled from the can. I mean holy hell
