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.

      Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.

      The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts.

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.

      Multigate electrical problem

      By Another JR · Posted

      The recall is for exactly this issue - those drain holes combined with the limited environmental capability of the tailgate electronics card inside the tailgate were a problem. The “safety issue” was the potential for the tailgate to spontaneously open, but all kinds of tailgate misbehavior can occur from water contamination of that control card.    There is no real fix yet. The initial recall just disabled the tailgate. Later, when parts became available, they would replace bad parts with new parts of the same bad design. My dealer is going nuts because the few times I let them get their hands on my truck, my tailgate is off due to a slide-in camper installation. They really want to cut my tailgate wires, but I won’t give them the chance. I will let them get their dirty hands on it when a real fix (redesign) is available.  My tailgate, which works just fine with sealant plugging the drain holes, will remain safe in a dry storage crate until then.
