Yeah, the catch can won't eliminate oil in the intake, just slows it down...

For 2020 I am considering a new Z71 TailBoss with the 6.2L motor in it, and ordering it with the Callaway 560hp package...  I wonder if they install a catch can?

Oh yes it is. The OP is taking things back several decades to the days of 'road draft tubes'. 40's/50's Pretty sure many on this site believe a PCV system is about 'pressure' when it is actually about

Ok, so nothing will happen with the motor...  Pressure can escape... it just won't be helped by the vacuum created by the intake, right? I know why they do it they way that they do, but if I don'

That makes sense I guess.  So is the consensus that I don't need a catch can?  I can just unplug the hoses from the intake tube(Airaid MIT), plug the tube, and connect the hoses to either a single pod

Can you not see what is included in the package from Callaway?

It doesn't give a lot of details on that particular truck.  I will have to ask my dealer for more info.

A Trailboss with 560hp would be a pretty badass truck though...

I have the 2018 Rocky Ridge Callaway SC560. It is a beast of a truck.

 

It started as a 6.2 8spd Loaded LTZ and then customized by Rocky Ridge and Callaway and retains full factory warranty. I also opted to purchase a 6yr 150K extended warranty.

 

It came with the AFM tuned out (didn't surprise me)

GenThree Triple Cooled Supercharger

Callaway Honker CAI

Callaway tuned stainless exhaust

4" coil over lift

Callaway 9 spoke wheels

Amp side steps

Carbon fiber interior

NO catch can

NO clean side separator

 

I installed a catch can and a clean side separator. I check and empty the can every 1,000 miles and depending how hard I drive the truck, it has about 2 tablespoons of crap in the can.

got that full factory warranty in writing?  Does it say what Factory?  If you have a copy of what they gave you for the warranty could you post it up?

They have some agreement with GM.  My dad just got a 2017 Callaway SC757 Corvette and it's all covered under warranty.  That's the benefit of going the Callaway route... you order it through your dealer, they take care of it, it's all part of the financing and they add their own warranty on top of the factory warranty from Chevy...

If you were to take a new truck and go to some speed shop and toss on a supercharger and stuff, your GM warranty is pretty much toast.  With Callaway, it isn't.

id like to see the warranty.  iv seen in the past were they let you think you have a GM warranty but its really the BS superchargers warranty that only covers so much per component. I find it hard to believe GM would warranty something they didnt design  and test for.  After all for a 3rd of the price you can do the exact same thing Callaway does. If GM will warranty it when Callaway does it why wont they warranty it if someone else does it.  Just contract maybe.

Go to their website, do some research. Same for Rocky Ridge. Both companies perform the work prior to sale of the truck. Both offer 3yr/36K through the dealership.

 

Here: saved you some time,

Callaway - Bottom of their webpage: https://www.callawaycars.com/homepage/cars/supercharging/

Rocky Ridge - middle of the webpage: https://rockyridgetrucks.com/lifted-trucks/lifted-chevrolet-trucks/silverado-1500-2500/black-label/

from calaway An optional 5 year/60,000 mile Limited Powertrain Service Contract which matches the GM powertrain warranty term is also available. The page they supply a link for that explains the standard limited warranty does not exist.  Cool you have to pay extra for the 5/60000 that matches the GM warranty but yes it is offered.  No GM warranty though. 

from rocky ridge  WARRANTY & MAINTENANCE 3 year/ 36,000 Mile Warranty on all Rocky Ridge Components. nothing saying that GM wont deny warranty on stuff like wheel bearings or rear end due to pinion angles.  But dealer would have to be real ass holes not to take care of you.  many dealers are though.

Anyone have the link to the amazon catch can? Or did you just search catch can?

Had you entered "oil catch can" in their search engine it would have returned more results than I cared to see.  Sometimes it is better to try the search before asking someone else to do it for you.

Correct, and thanks for stating the obvious. I wanted to see which brand and which specific catch can was mentioned here. I'm not an idiot, and know how to use a search engine.

 

Maybe ask clarifying questions before being a dick?

All these companies are is upfitter's, just like motorhomes, ambulances, etc. The upfitter is the warrantor on the modifications, NOT GM.  So if you have such a vehicle and you go to a different dealer than sold you the vehicle, good luck.

 

Local twp FD is fit to be tied with Furd Ambulance diesel they have. Ford says the upfitter is responsible for the dead battery problems, upfitter says it Ford and they should pay, neither will pay. If it was just the harness, it would be several 100 dollars but the labor to track down the problem is in the 1,000's.  TWP is suing the upfitter.  The local Furd dealers did not sell it, it was out on bids, a gov't grant where a big fleet dealer in another state got the low bid, it was 100's of misc emergency vehicles in the special purchase, they waited almost a year to get it..

What I wish there was, was a way to route the crankcase vent to the exhaust manifold... Let that draw the oily air via vacuum and have it bypass the motor entirely...

You can do that on bikes, which normally dump the crankcase vent into the airbox...  they also have a hose off the airbox that goes into the exhaust manifold to help "clean up emissions"...  So you plug the airbox, and route that hose to the exhaust(normally called SAI or PAIR, depending on the make of bike) and connect the crackcase vent to that, and it will pull a slight vacuum on the crankcase...

 

I have a  set up like this actually. 

 

You will need Moroso Part Number 25900, and put the PCV into the exhaust after the O2 sensors like I did.

 

I want to make a video about it on my YouTube channel, also curious to see how mad treehuggers would get

Have you checked your fuel trims after you breather valve cover mods? you might be causing issues  

 

seen this before on racecars, but the vacuum on the engine case is much lower than a stock pcv would draw, so it's not optimum in regards to the benefits of a pcv system, maybe utilize both ideas somehow

 

you could install a super tiny motorcycle turbo dedicated only to crank case vacuum,  run it off of an exhaust primary you only need enough low pressure to keep the cank case in low pressure state and blow it out the muffler

      OCI, not when but why?

      By Chuck FB · Posted

      I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.

      Tranmission stays in Low

      get a good code reader, and find out what problems the truck has noticed by reading codes. cheap ones can only get basic engine codes, you may want to get one that can get codes from all the computers in your truck.

      This is sort of my point, salvage yards aren't overflowing with all these 'poorly' maintained trucks - excellent/good/servicable condition otherwise, salvaged only as a result of a bad engine from poor oil change regiment.    In my area, there are no 2007 to newer gm trucks/suvs in any salvage yards. A few are in the 'recyclers' with very obvious reasons for being there - wrecked.

      Stabilitrak conversion to Z71

      By asilverblazer · Posted

      Stabilitrack was a stability control, traction control system, that functioned independently from the transfer case.   Z-71 has nothing to do with the transfer case or differential.   If it does have an AWD system, my memory recalls this being specific to the Denali trim, converting won't be as simple as swapping out mechanical parts like differentials and transfer cases. It will require reprogramming at a minimum. Long story short, not likely worth it.   Pulling a fuse, may disable the AWD system, it might also prevent any other transfer case functions.   However, the AWD case was generally based on the same transfer case you refer to in the 2006 Suburban. If it still has a 4-High and 4-Low where the transfer case locks and splits power 50-50 front to rear, what are you gaining by changing anything? A true-rear wheel drive only, what good will that serve? Not enough to go through the trouble of changing out all the parts.    Generally, all the factory systems will handle a 33" tire and re-gearing. Probably a 35" tire too, if you aren't driving like a caveman. If 35" tires are in the plan...   If you do plan on driving like a caveman or are fully committed to 35" tires, an entire re-think of the build is probably in order. Starting with square one, an IFS front end isn't going to be the best starting point for 35's and caveman driving.

      Oil Consumption

      By PunchT37 · Posted

      1/2 qt over full ain`t gonna hurt $h!t. Most times, a whole qt won`t either. Most have windage trays now. As long as the crank isn`t slapping itself in the oil, it`s not the end of the world.   We used to overfill 1 qt at the track, at race time. Better to have it over full than having the pan sucked dry at 6500 rpm`s.
