The “TUNE UP” is DEAD! Dual Spark HEMI! (Injecting liquid into the Intake)

How to do a tune up on a HEMI 5.7 in a Ram 1500 4x4. This same engine can be found in several different cars and trucks. We will be removing all sixteen spark plugs from this v8 engine. This is known as a dual spark ignition system. We will replace all of the spark plugs and then manually clean the throttle body. Afterwards a pressure vessel will be filled with an intake, valve and top cylinder cleaner. When the cleaning product is then processed through the engine, the spark plugs will be removed for a second time in order to use borescope to visually inspect the pistons in order to determine the effectiveness of the cleaner on an engine with carbon buildup.

[@1973retrorabbit]

Curious here, have you opened one? I'm wondering how the reverse function works, if it's a "sprag clutch/ bearing", as I only know those from automatic transmissions, to reverse their direction, you'd need to fit them backwards. 🤔 Obviously, there's something designed in to make it reversible.

I have a 2014 version of that same engine, also in the pickup. I struggled similarly to you when I changed my spark plugs. Your experience and efficiency getting through the job actually showed, at least to me. I did use a different spark plug socket, which may have helped me out. It was also pointed out that I could have pulled the fender liners and come in through the bottom, and it likely would have saved time.

I felt my blood pressure rise watching you do the drivers side. I had a Charger with the same 5.7 Hemi for a few years that I gave to my son. I am no longer a fan of Mopar after replacing the engine on that car. Everything was more difficult than it needed to be. There was also a long list of "for this particular engine".

[@scburg66]

Love Ray’s videos!!!Question though. “We do not start threads on spark plugs with the electron ratchet, you may cross thread an aluminum cylinder and that would be bad.” On the driver’s hard side, drop in the plugs, hit them with the electron ratchet. Did the hand start get cut out or did Ray just do what he said should not be done? 😮

Back in the day when dealers started selling fuel system cleaning we invested in a Moto-Vac machine to be able to offer the same service. It was a hard to sell service at first but testimonials from those who had it done increased sales and allowed us to help more people with this valuable service.

[@shadowopsairman1583]

It temporarily helps, I know this because a 2004 tahoe sat 5 years, started, had a p300 code, I pulled all 8 injectors and looked in them each, had what looked like crystalization/stones in the screens so unless if the injectors can be pulled and cleaned by breaking up that trash using a plastic scribe and sprayed out using a cleaner, just hooking up to the fuel system to pump a solution through is not the end all fix.

[@anthonygeiss3708]

Moto Vac does that Vac money from the customers pocket.

[@denniss5512]

Hey Ray, I did this service to my 2010 Jag XKR. The direct injection made the valves all gummed up. Like one of Eric's I do Cars videos. After watching your videos a while back I bought the cleaning setup. Napa had lot's of brands but no BG but I went with a dual product setup like yours. Like this, it took a couple of days but when I went back into it with my endoscope it was dramatically cleaner. I agree, it takes a coule of heat cycles to break the gunk off but you can tell because the exhaust stops smoking. Easy process to do after oil changes. Makes the neighbors wonder tho.

[@scaleautoguysworkbench]

I have a 12 Ram 2500 with the 5.7L. I just did this repair last fall. Not an easy thing to change the plugs on these trucks. The rear plugs on the passenger side are difficult but the drivers side third and fourth plugs are super difficult. You really have to contort your arm and wrist to get the coils off and on as well as change the plugs. With my truck being a heavy duty 4X4, even at factory height, it makes it so that you almost have to lay on the engine partially to get to the driver side plugs. I cuss the entire time and you don't want to know what I think about engineers while I am working on today's vehicles.

[@ken2tou]

I just changed the plugs in my 2013 Ram. On the passenger side, the wiring harness can be moved by detaching it from the firewall. The heater hoses too. It is a lot easier to remove the plugs. The wobbly bit is essential on the drivers side, nearest to the firewall. The the brake vacuum assist can be easily relocated for access. I ordered iridium plugs off Amazon, specified for my engine. Every one of them were gapped improperly at 55, rather than 43. I adjusted them and they’re working great. My concern at this time is, I found out after installing the plugs, Champion is an inferior product. I’m not inclined to change them again. But, watching closely, just in case. My truck just turned 70k and runs great!

[@joeharrison696]

So inconclusive test because if the snake oil have an effect it takes several heat/cold cycles. You should test it on your Interceptor taking photos before, after a go, and after a week.

[@thomasswalley1075]

I bought a magnetic sparkplug socket at O'rielly auto parts. Best investment ever! I never have a problem with the plug falling out of the socket and compressing the gap. There isn't a rubber holder to stay on the plug when you pull the socket off the plug. It's a great invention.

My 2016 ram 5.7 called for .044 and mine also came out the box at .040 and installed them and it runs perfectly.

[@garyfowler3393]

I like your comment about relative ease of tune up. I had my Honda CRV in at the dealer for a diagnosis of a strange engine noise ,a rather low rattle like noise at 1500-2500 rpm that then disappears at higher rpm. They couldnt find the cause of the noise and only suggested a "tune up" which entailed cleaning the throttle body and changing the spark plugs for the paltry sum of $600 plus tax (and shop consumable) of course. They charged me $175 for the pleasure of looking at my car for an hour and I declined to give them another $600 and instead bought a set of plugs and some throttle body cleaner and did the work myself. The car only had 50K mileage and when I removed the plugs, they looked just like the new ones and the "carboned up throttle body" was perfectly clean just as I suspected. I did replace the plugs, sprayed a $10 can of cleaner into the throttle body and intake and test drove it. The noise is still there which was no surprise. I guess I will follow the dealer suggestion and just drive it till it throws a code that can be checked out.

Just a couple days ago I replaced both exhaust manifolds on a Dodge very similar to that one. Doth manifolds were very very rusty and each side had multiple broken bolts. Extracted the broken bolts with a welder. Also replaced all the plugs and coils. Ignition coils were all getting green corrosion on them.

[@jdesaavedra0432]

It's interesting that all this contamination of throttle bodies and intake valves are the result of the PCV running crankcase blowby through the intake. One would think there would be a more efficient method of preventing blowby from entering the atmosphere without shortening the life of the engine.

[@Bowhunters6go8xz6x]

The Walnut air blasting kit is (hands down) the absolute best way to clean the valve stems and intake runners inside the cylinder heads on Direct Injection engines (it cleans them to new condition). The BG cleaner you used can do a good job on the piston and valve tops, what would probably help is to also add BG 44K fuel system cleaner to the gas tank and take it on a long highway drive so that any loosened carbon will be blown out over a 1 to 2 hour drive at highway speeds.

[@jdesaavedra0432]

Two aspects of maintenance that made the most difference in operation was cleaning the throttle body and using BG EPR which removed carbonized oil from the oil rings. This was done around 180,000 miles. Spark plugs, filters, and PCV service at different intervals made no difference. BG EPR is the only snake oil product I have tried and found to be effective.

In many cases of direct injected engines, the valves get so carbon encrusted, you have to use walnut shell media to blast it away. A catch can for the PCV system helps keep the intake cleaner.

[@Alberta_Redneck]

what did wonders for my ram and hemi was a catch can. kept the pistons very clean.

[@astrangeparrot]

I've done the same with a cup of h2o sucked into the intake through the brake booster vacuum line. Pin the throttle at about 2,000 or have a friend do so. Smokes like a blown head gasket while you're doing it, shines the pistons up like nobodies business though. The cleaners do work better, they just have a cost for the speed/convenience. No judgement to Ray for using it, winds up being the same or less cost wise because of the billable time needed with plain water.

It stopped minor oil consumption and improved smoothness on the 4 cyl 2006 Highlander at 180,000 miles, and it stopped smoking on startup in the 2003 4 cyl Camry with 110,000 miles. I can't imagine any benefit on these port injected engines that are running perfectly.

In the days of old we used to mist water over the top of the carb at 2000 RPM and would do similar things to the carbon in the cylinders. I'm m sure that the atomizer works better than the "Windex" spray nozzle did though.

Ray i love your vids and my wife and I want to take a road trip and visit your shop.

Sone of the Chryslers used NGK's. I always put them back with Champion if I can (if they were also an OEM plug), cause they are cheaper. I found this on some 300's as well.

I've had several Mopar vehicles. It's my understanding that back in the good old days all Chrysler, Dodge, and Plymouth vehicle's came from the factory with Champion plugs. I use the copper plus.

Quick question, you atomized the liquid only for it to pool on the butterfly, so is there any real point in the atomization of the liquid in the first place? (Genuine question not REEEEEE LOL)

[@nicholassammauro4941]

Great question. The atomizer applies the chemistry at the rate that’s effective to saturate the carbon….It’s wet because it’s working. The goal is to scathe clean vs chip away carbon. The cleaning process will continue over the next few days…The chemistry is still working along with the 44K in the fuel tank. This is a great video showing the correct way to apply this Svc. *I am Ray’s “BG GUY” fyi

I was surprised to see those spark plugs on the "hard side" started with the electronic ratchet. Ray is the expert, but as an amateur I would have been very nervous doing that.

Ray reach’s and turns the valve open. Ray says “now I’ll hook up shop air. Ray hooks up shop air and says “oh look, it’s already spraying, the valve is open”. 😂 I think he does that for comic relief.

If you do Honks for Safety merchandise, I'd love to see an angry Canada goose with it 😂🤣

Damn it’s already 80+ degrees. Up north we had around 40. It’s getting warm. lol.

Used to be in the old days, run water through the intake system and bust out all that carbon. Now day's we have Gumout, SeaFoam and many others, which works wonders. Gumout is probably the best on the market. Just need to let it soak for about 24hrs, fill the cylinders, pull the plugs, spin it over and done. Now, what this all means to me is, all this carbon is now going to be hanging out in the cat convertor, one reason why many didn't have cat convertor's or removed them altogether. I've seen you use this method before and I admit it does work but for those of us that don't have such nice fancy machines, as the saying goes, "mechanic in a can" works just as well. Cheers :)
