It is a popular topic, read some threads about it.

 

What you think is a must is where others will say it's a waste. I've owned a DI trucks for over 3 years, never installed one and never will. I've even had my intake manifold off at over 100k miles and it showed me no cause for alarm with my intake valves.

I'm actually surprised that the catch can is not very popular on this forums, I will definitely  be installing  on my new truck, I will have one at home b4 I pick up the truck and install it as soon as I get delivery of my truck.

Just do a little search. They do have some popularity. Plenty of wars been fought over them just like choice of oil, oil filters, throttle body spacers etc................

 

It's just quiet for now

  Show us your before and after oil analysis, crankcase vent calculations, fuel economy, oil usage and might as well get a good ASTM D86 distillation of that residue in the catch can to show us what you are actually catching.

I just installed the J&L Oil Separator. It's a very easy install. The instructions say to move the air box out of the way, but I didn't find that necessary.

 

It'll be interesting to see how much oil collects in there and what it looks like. It can't be a good idea to send that dirty oil back into the intake.

UPR products by far has the best quality in my opinion. Massive can with multiple sections that solidify the vapors. 1 in and 2 outs. 1 for idle and low rpm the other for higher and WOT. Barely have any vacuum in intake plenum at WOT. Also have a separator for the clean side for backflow.

Not sold on the idea of an oil catch can. I do know of people who have had giant vacuum leaks and poor performance on V 8s caused by leaky or defective catch can vacuum hoses and connection's. I was a Fleet Manager for a big city in the Midwest for 25 years and we never used catch cans on our Di engines in our fleet.

      Trading 7.3 (Godzilla) for G.M.C gas

      By James Beyer · Posted

      Congratulations Isttype, on your gmc. Really like my 2024 2500hd sle doublecab now with 85,500 miles.  I checked the oil today at 4800 miles since last oil change and barely reading on the stick.  I don't care if GM says it's Acceptable adding a quart every 2000 miles because that is 100% BS, It is not a 1966 Harley Shovelhead! Sounds like it's setting up a future failure like I had with my 1500 6.2l. Other than oil consumption problems, I really like the 6.6l gas and 10 speed is really nice.  Towed a light 4000 pound trailer last week and averaged 14 mpg.  I was pretty impressive that a 7300 pound gas truck did 14mpg towing, Later-

      Long Term Cold Cycle Limited Testing   Back to the 1990's and XOM's million mile test. Since then there have been others and there will be more. Schaeffer's, AMSOIL to name two. Of these Schaeffer's is the stand alone which I will explain in a bit later.    http://papers.sae.org/600190/:   http://papers.sae.org/850215/:   Up to 75% of  engine wear occurs on cold starts. These two links (above) provide the technical reasons for engine wear. In a nut shell, and by a large margin, cylinder wear is what takes out most motors and even with a pre-oiling system that part of the engine is dry enough on cold starts and cold warm up to pierce Stribeck.   So when you put a motor, or a car, on a dyno for a million miles stopping only for oil changes, (yes fuel is uninterrupted) or break down maintenance, you are depriving the test of the most important part of it's wear cycle. Yes a million is then a pretty easy walk even for a mineral oil under those conditions.    How about cleanliness during the long test cycles? Same thing. Varnishes that stick rings and insulate parts are laid down by repetitive 'heat cycles'. It's the cool down the precipitates the varnishes. These long runs also hinder acidic attack caused by cold start richness and less than optimal cold start ring sealing. They hinder water formation and enhance breathing of the crankcase; the petri dish of acid formation, the first step in sludge formation, amalgamation and precipitation. These motors are also monitored and controlled for water and oil temperatures to within the "normal operating range".      https://www.swri.org/sites/default/files/sequence-iiih-test.pdf Note the test sequence in some boutique oils literature for testing, API IIIH, is not the standard used for the ILSAC G7 testing. Does that mean it is irrelevant? No, not as used. As used as a 'visual guide' it makes it's point. The G7 weighted piston deposit minimum is lower.      Back to Schaeffer's. That was a cyclical test of an engine in fleet service and not a dyno mule and if you saw the video it was not mirror clean but wear was low.    There are oils like BioSyn and other 'Renewable" source oils that taught cleanliness and have proven themselves in fleet testing. Havoline an other example.    The newest ILSAC G-7 test prioritize cleanliness, LSPI mitigation and fuel economy OVER WEAR. In comparison Porsche C30 Specification Verses ILSAC G-7 Specification below:      Some will balk that this graph isn't apples to apples and I will challenge that in that this graph represent the SPECIFICATION and not the any One Oil Performance.   It is absolutely possible to minimize wear, maximize cleanliness and mitigate LSPI etc., It just isn't cheap and currently I see none that are not walking toward profit over performance.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I don't think you will need a split, separate product, etc., the OBD port should be able to deliver everything you need. Since your device would be plugged into it all the time, it wouldn't miss anything.    Hardware in this case will be the easiest part of your project - ELM 327 devices will already deliver all the data you need. Reporting/software is where your advantage/marketability is.

      It has happened to me a few times. I carry a jumpstart-tire inflator with me.
