That's why I'm working building a meth/alky kit in the next few months. I figure it and the catch can will be great with a future tune.

 

For a temporary setup run the hose from your winshield washer to the place you're going to inject it. I'd just put a washer nozzle in the plastic duct in front of the throttle body. Solder or squash the orifice down to about .060 and be done. You can control it with the washer switch. Pull the wiper fuse. Heck, you can shoot the blue juice in there and get good results. It's mostly water and alcohol.

yep, gotta admit the scraper is genius. Probably more reliable than the wife. DEFINITELY less mouthy about the situation.

I just did my truck with seafoam. I can't tell a huge difference yet, but we will see over time. Used my window scraper to keep the rpm around 2000.

Ok, so lately I've been noticing the 6.2 stumbling a bit, hesitating, lower mileage - even more than expected for winter - etc. and began getting more concerned about intake valve buildup. 26k miles

That's definitely simplistic...

 

The good thing is that with the AFE Stage II, is that I will not feel bad about tapping the elbow. I'm guessing that the spare battery tray was put there just for a meth/alky tank. Been looking into Devil's Own kits.

I just did the BG treatment at 16,500 miles. I can honestly say the truck runs smoother, has more power, and the mpgs seem to be up a lil. I'm ordering my catch can next week, and will probably do the BG treatment every 10,000 to 12,000 miles for as long as I own the truck

 

Scheduled a service appointment with my mechanic for tomorrow to do the BG treatment. I'm hoping to get some before and after pictures from his borescope. I will report the findings here if I do. When you did your BG service, did they change your oil afterwards?

Nope, dealer is changing the oil tomorrow though

Ok yeah I didn't plan well for this. I did the dealer free oil change a few weeks ago and you're supposed to change oil after the bg service so now I have to pay to change it again after only 800 miles. Oh well. Next year I'll be able to do them both at the same time since I'll be done with the dealer changes and will be going to my side mechanic by then.

...and effective.

 

We did this on turbocharged engines running 30+ psi and controlled the pump using a oil pressure switch placed in the intake manifold. When the boost came up to 3-4 psi, the switch tripped and water injection started.

 

For just occasionally cleaning an engine, a manually controlled injection system you can engage when under load is all that is needed. If you're trying to solve a detonation issue, that's different.

Yeah, I'm running a devils own water/ meth kit on my 450whp srt4. When we took the motor apart my intake was clean enough to eat off of. Great for detonation when raising the afr, adding more timing and turning the wick up.

I'm hoping that down the road I'll have a reason to have a detonation issue, lol. That's a long long way off though.

The good news: I did the BG induction service yesterday and the truck seems to be running great afterwards, no issues so far *knocks on wood*

 

The bad news: I could not get before and after pictures of the valves. The way the intake is designed on these engines, you can't get the borescope in there because of all the bends and turns. We would have had to remove the intake manifold to see the valves and I wasn't about to do that on an engine with only 15k miles.

 

So the catch can debate will have to rage on. I will say I have not really noticed much of an improvement with the truck as others have reported. It honestly wasn't really running bad before I did the service, I just wanted to get in before 15k miles to take advantage of BG's warranty. So if guys without catch cans are noting an improvement in performance after the service and I'm not noticing much of anything, I'd argue that's evidence in favor of the catch can doing what people say it should be doing....keeping the valves clean. I only had 11,500 miles on the truck when I installed the catch can so there wasn't much time for a lot of build-up to happen and dramatically affect performance, although I don't doubt that some buildup did occur and the service yesterday took care of it.

 

I'm going to post this in the catch can thread as well.

 

 

EDIT: Forgot to add it was about $78 in materials and $117 in labor for the BG service so $195 total. You have to get your oil changed as well afterwards so factor that into the total if you're considering doing this service.

Been really curious about this... I'm installing my catch can this evening and I think I'm going to run up to the auto parts store and buy a can of CRC for good luck. My truck has 18k on it and I'm better off late than never with the can and intake cleaner. I'm going on a 2500 mile trip next week and just bought my oil but I'm going to clean out the intake before I do the oil.

Might be a dumb question but here it goes... Instead of putting the CRC valve cleaner in the front of the intake, can I spray it in the outlet hose coming from the catch can?

I don't quite understand which hose you mean. Can you be more specific? Do you mean squirt it in the PCV valve where it goes into the intake manifold? I would think it would be fine, if you disconnect the PCV valve, seal around the spray can nozzle so you don't have a large vacuum leak. Maybe a small cork with a hole in the middle for the spray nozzle straw.

Exactly. I'm sorry if it might have been confusing.

Quick, dumb newbie related question. Most of the catch can I am seeing are sealed systems that require unscrewing and draining on a regularly basis. Are they designed as a closed system on purpose to prevent vacuum leak issues, or is it possible to have an open system?

 

As an extreme example, would it be possible to have a catch can system with a bottom drain that just remained open all of the time. And if so would it require one way valves on the intake and outlet lines? (I'm in no way advocating polluting by letting oil drip onto the road, I'm just trying to be simplistic for the sake of my question and understanding.

That would be called a vacuum leak.

      2023 DRW Wheel Liners

      Did have to make 1 modification because of the WeatherTech rear mud flaps and that was needing 3 longer screws than what came with the install package. 😄

      Picked up the liners yesterday. Installed passenger side WITHOUT any modifications. All mounting holes lined up perfectly. Rain is interfering today with drivers side. Very Happy! Will add pics when finished

      As a matter of amusement I’ll leave this conversation with this. Do you beat the government average fuel estimate? Statistics are a guide to me. Not a rule. Someone once said I have to have the last word. If true and possible may be. I’ll blame that on working in a family business.

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

      By bluev8 · Posted

      That is a fair point, and I agree that trying to log “everything in the truck” would be the wrong direction.   There are a lot of modules and a lot of traffic. If the product became a full-truck datalogger, the amount of data would get huge very quickly, and most owners would never use it.   I think the first useful version would need to be narrow: - powertrain-side event evidence - selected high-value parameters - communication / voltage / reset events - pre/post event window - short report first, raw log only as backup   One distinction I should make is between active OBD/PID polling and passive bus capture. If you are polling PIDs through OBD, then yes: the more parameters you request, the lower the effective sample rate becomes, and you are adding diagnostic traffic to a vehicle that is already busy running itself. With passive CAN capture, the recorder is not asking all the modules for data. It is listening to traffic that is already on the bus. So it does not consume vehicle bus bandwidth in the same way that a scan tool polling hundreds of PIDs would. But your point still applies in a different way.   Even if passive capture does not add bus traffic, the recorder still has limits: - processing rate - storage rate - timestamp accuracy - decoder workload - event filtering - report size - user attention span   So the answer cannot be “log everything and let the user figure it out.” The product would need to store enough raw evidence to be useful, but only decode, graph, and present the important parts around the event.   A practical report should probably show: - what triggered the capture - how much pre/post data was preserved - which selected parameters changed - how those values compared to baseline - whether the same pattern happened before - whether any voltage, reset, bus-off, lost-message, or communication fault occurred - selected graphs around the event - raw data only as supporting evidence   So I agree with you. More data is not automatically better. The real product is the reduction from raw data into a useful event report.

      By bluev8 · Posted

      That makes sense, and I agree with most of that.   I think the product would need both: 1. a default powertrain template, so it is useful out of the box; 2. user-selected priority parameters, so the owner or shop can choose what they want to see first.   Different users are going to care about different things. One owner may care about oil pressure and voltage. Another may care about misfire trend, AFM/DFM behavior, or U-codes. A shop may want communication events and repeatability first. Your baseline point is probably the most important one. Raw data is not very useful unless the report can show what normal looked like for that vehicle under similar conditions.   The way I would think about it is: - start with a basic known-good baseline - learn normal behavior for that specific vehicle over time - allow the event to be overlaid against baseline - show whether the event was a one-time spike or a repeatable pattern - provide a simple severity level, but with clear limits on what that severity means   For example, early severity could be something like: - Info: event captured, no obvious abnormal pattern - Watch: value moved outside baseline, but not repeated - Warning: repeatable abnormal pattern under similar conditions - Critical: communication loss, voltage drop, bus-off, reset, or severe repeated event   I would not want the first version to say “replace this part.” That would be overclaiming unless there is repair-confirmed data behind it. It would be more honest to say “this pattern deserves inspection.”   On the OBD port question, I think OBD absolutely has a role. OBD is probably the right place for: - DTCs - freeze frame - VIN - calibration information - normal scan-tool parameters - Mode 6 / enhanced diagnostic data if available The reason I am still looking at an ECM-side recorder is that the failure may happen before anyone connects a scan tool. If the owner plugs in a scanner after the event, the pre-event evidence may already be gone unless the ECU happened to save it. So I do not see this as “OBD versus ECM-side.” I see it more like: - ECM-side recorder: always armed, rolling buffer, event evidence - OBD/DLC companion: DTCs, freeze frame, VIN, calibration, normal scan data - phone/cloud: status, notes, upload, report generation, notifications   I agree that phone connection and push notifications would be useful. I just would not want the phone or cloud connection to be required for capture. The recorder should save the event locally even if the phone is not connected. The phone should help with event marking, download, notes, upload, alerts, and report viewing.   For a default GM V8 event report, would this list make sense? - RPM - calculated load / MAP - throttle position - vehicle speed - gear / torque converter state if available - coolant temperature - oil pressure - oil temperature if available - battery voltage - commanded AFM/DFM state if available - actual AFM/DFM state if available - misfire counters / roughness by cylinder if available - fuel trims - relevant U-codes / communication events - bus-off / lost periodic message / module reset / voltage drop events Which of those would you remove, and what would you add?
