Sorry if this has been discussed before. Did a search and found nothing.

 

Has anyone had any issues with warranty work after installing catch can. Was about to order one but wanted to check here before spending money.

 

Thanks

This has been discussed ad nauseam.  Some love them, some hate them.  I am of the opinion that they can only help by trapping the junk circulating through the PCV system.  After all, it is just a "filter" placed inline in the PCV hose.  If/when I have to take my truck in while under warranty, I will remove the can.  The one I have uses quick connects and I can have it installed/uninstalled in a couple minutes.

My philosophy with mods is this: If you're worried it could cause warranty work to be denied, don't do it until warranty expires. If you don't care about the small chance of a warranty claim, then just do it.

 

Here's the latest intelligent catch can conversation from earlier this month:

There has been some instances where it has caused a warranty issue to be denied, not often but it has. Yes, it has been discussed often around here and a search would have easily brought that up; it is also discussed in many of the catch can threads...

If your truck is new or low miles i would get one. Dealer has to prove that the mod caused the warranty needing service to deny it.

For example if you have a catch can and your Head light or something electrical goes, then cant say oh you have a CC so no warranty.

Meh, not sold. Any time a warm air circuit expands into an unheated chamber, you get "rain out" (think of sweat on a cold beer can opposite since warm is inside). Thats the "proof" cc people use to justify the efficacy (murky fluid in the can). I would save the money and buy a walnut blast if you actually do get valve deposits - that way all your issues will get completely resolved...

You nailed it. Catch cans are a joke and people buy them thinking they work. Can sweats with oil residue inside means murky water at the bottom people say Hey it must be working company that sells them say hehehe yeah they work buy another one for your other car.

This is like Republicans debating Democrats.  ?

 

I've seen the "with can" and "without can" results on the inside of an intake manifold and the backside of the valves.  I'm judging the effectiveness of the catch can by how my engine internals look - not simply by the presence (or lack of) material in the can.  I will run one from now on based on my own eyeballs.

 

As for the can "sweating"....that's exactly correct.....that's why there is material with lots of surface area inside them (stainless mesh, perforated baffles, etc)....so the vapor can collect, cool, and condense.  What is the harm in putting a simple "filter"; i.e. catch can, inline in the PCV hose to catch crap?  Is it the money?  I've seen lots of people spend a couple hundred dollars on frivolous things for their trucks and no one bats an eye....but spend it on a catch can and out come the wolves!  ?

I purchased one for my truck, even posted about it here.  There is little to anything in the Can after 5k miles.  My L87 appears to run pretty clean compared to my old 8.1L.  My old Avalanche2500 used to fill the can every 2.5k miles.  But I used to dog the hell out of it, and was at WoT alot.

Heynow, Im all for them.?

 

OP if you want info on the how's and why's of a can check the tuner car boards.

 

That is the only place I found for a real discussion with problems (Oil soaked intercoolers and gunked turbos) and solutions you seek.

 

As far as warranty, there are good dealers and there are shady dealers, but removing it before needing major warranty repairs is simple enough.

I'll be buying a Mighty Mouse can as soon as they release the new bracket for 2019/2020.


Been talking to them about this. I think one of the Duramax brackets will fit on the battery bracket by the AC line and let you mount the can there. I need to order one and try it.

Thanks, please let me know if it works out.  I contacted them a week or two ago, and they said they were working on getting one fabricated... But I hate waiting.  If it works, please post the part #, and I'll be right behind you.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Thanks - I wasn't quite caffeinated this morning. 2:1 makes sense, turning the crankshaft 360 degrees will turn the cam 180 degrees, and had I done that, the cam's dot would be at 6 and the crank's at 12 again.   I went ahead and took the sprocket off anyway, aligned everything dot-to-dot including the balance shaft just for s&g. I'm glad I did because I discovered no Loctite on the timing sprocket bolts. Maybe it's not required, but at only 20 ft-lb torque spec, those bolts aren't in there very tight. Cleaned and reassembled with some thread locker and torqued.   A general observation: Less is more with RTV. If a little doesn't stop a leak, a LOT probably won't, either. RTV is thinly veiled revenge, in a tube...

      The timing marks are ok, that is #1, you can turn it over until they line up and it won't change anything, the crankshaft turns twice for every camshaft revolution, I have always set up SB Chevs as your pic shows using a straight edge

      Someone's been here before.... There is a receipt for a 3-piece timing set, purchased earlier this year.   Is this picture something, or, nothing?   I have the timing cover off and my crank is perfectly TDC and the keyed gear's locating mark is dead on 12 o'clock.   The cam gear locating mark is also at 12 o'clock. Now, I'm not an expert, but all the install guides say the two locating marks should meet and be perfectly aligned when installing a timing set. The mark on the crank should be dead on 12:00 and the cam gear's mark should be dead on 6:00, and both marks should be perfectly vertically aligned.   I believe the timing gear is keyed or has a dowel that ensures it can only be installed on the cam in one position, so I have to believe the cam is out of phase somehow. At the very least, with a triangular bolt pattern, it can only be installed in one of 3 different positions.   Before I pulled the front cover, the truck was running alright, no service engine soon lights except an occasional P0172 / rich condition. Timing -16 timing at idle (should be +16), and total -35% fuel trim, two conditions I haven't been able to figure out.   In related news, my injector tested pretty well, wasn't leaking, but I had it rebuilt anyway, and it's on it's way back to me.         Along with this discovery, the good and bad:   Good: The oil pan seal appears undamaged.   Bad: -The timing cover has been reused, and the positioning dowels have been broken. That could explain some of the leaking. -Some kind of white paste or grease was used to try to seal the oil pan seal and timing cover (since wiped off..). -Then, someone globbed silicone all over the front of the cover and also buried the ckp sensor in it. But, they didn't put any inside the cover or use RTV to try to seal the oil pan seal with the timing cover (good).

      PF63 Oil Filters Going Away?

      By Grumpy Bear · Posted

      The guy that owns K&P filters last I checked in with him has over 300,000 miles on his Dodge base Hemi using his own 35 micron absolute stainless mesh filter from its first oil change.    The GM study I've posted a dozen times shows the relationship in engine life based in multiples of base units, not miles or years. That is the base unit is the number of miles the motor ran using the reference filter efficiency.    The above two paragraphs dismantle anecdotal arguments IF one changes oil often enough to prevent particle formation and the motor is in otherwise good shape. That is not full of silica (no air filter) or suffering a metallurgical issue that is not part of the lubrication discussion. Poor heat treat in example.   Data from UOA's I've reviewed from more than a few engines can show remarkably broad variations in oil cleanliness using the exact same filter over the course of an engines life.     Lastly there is the common sense of it. Wear debris WILL circulate the engine BEFORE it ever sees a filter in route to that filter and WILL harm the pump which NEVER sees filtered oil.    Alpha question then becomes, given the facts, how long do you believe is a reasonable service life from a vehicle you are certain you will not pass down? That is the junk yard will be it's resting place when you're done with it? (the moral issue most don't care about).    Omega question is then how diligent are you prepared to be in general mechanical, air & oil maintenance? Preventing particulates and keeping them sufficiently dilute; preventing the precursors from generation, amalgamation and precipitation.    If I get a good look at the engine bay of a vehicle I have a fair idea of the owners commitment to the inside of the power train. That 30 micron WIX is still more efficient than a sieve.

      By Tyler Gibbs · Posted

      It also depends on what criteria someone is using for “best” when talking filters.  Are we going off best efficiency?   Best quality/QC?  Etc. because the two may not mutually exclusive.
