  • In this video I have a look at a 2004 Hemi Dodge Ram that was dragged in as a no start. Doesn't take long to find the root cause of the problem and the misfiring cylinder and it ends up being a pretty easy fix in the end. -Enjoy!

    I have seen several Hemi's with broken valve springs and rocker arms. When I was Fixed operations manager at a full line Chrysler dealer one of our rookie, fresh out the cap program, techs had one with a misfire code. He swapped the coil and injector and the misfire stayed in the same cylinder. He said he didn't know what was wrong because it checked out electronically. I told him to rev it up, it was popping in the intake so I told him to pull the valve cover. because there was a valve train problem in that cylinder. He pulled the cover and there was a broken rocker arm. He asked how I knew that by listening to it. My reply was remember I was a tech for 30 years before I was a manager, when I started in the business in 1968 there were no computers. You learned a lot by observation of symptoms.

    that make videos on "How to work on cars," but out shine them all, because your ability to diagnose problems when you make a video. Anyone can replace
    parts, and hope for the best, but your ability to explain the procedure and inner working of a car is uncanny. Your are a real Gem, and I don,t say that lightly.
    Your are an honest man with a good heart, and people are lucky to have you work on their car. And no, 99.99% of the people can not do what you do, and even
    if they could, they choose not to do, because, they are not HONEST. I know it is hard on your body working as a tech, but you would make an excellent teacher

      MeVsMe Not sure what warranty has to do with technicians’ ineptitude in diagnosing. Hadn’t really considered it since the last vehicle I had that was under any kind of warranty was in 1995. However, after considering your proposed excuse, I’m pretty sure that whether a vehicle is under warranty or not has nothing to do with the techs’ knowledge or training level. And, since the instance in question was a 2003 Ram with somewhere between 160-170k in 2015, that would make that 12 year old vehicle ineligible for a warranty but very feasibly diagnosed. In fact, I was able to do it in my driveway with a cheap Actron fuel pressure gauge and an ignition key and my brain- no multi-thousand dollar high tech equipment needed. Which brings me back to my point; Eric did a great job of using his noggin instead of a crutch.

    These 5.7 Hemi's are known to have failed roller lifters causing scoring on the cam lobes causing inaccurate valve intakes & exhausts seals thus low cylinder compressions.. The needle bearings of the lifters are falling apart & metal grinding away on the lobe of the cam.. Lucky for this customer just a broken valve spring & not a failed roller lifter a major repair, I traded in my 2011 Challenger R/T for this reason didn't want to deal with this kind of failure if it were to happen lucky for me it didn't happen before I traded it in..The newer 5.7 Hemi's don't seem to have this problem just the older models 2009 thru 2014. just thought I'd share with your viewers..

    Great use of the pressure transducer. I have found that the shape of the waveform from it as well as the max and min values can give valid diagnostic information. The rate of change of pressure on the up and down slopes can say a lot. Storing the profile for all cylinders and comparing them can point to issues more than a simple compression test can. The rate of filling and emptying of the cylinders is very useful data.

    I traded a rusty little Dakota for an 03 Ram with a Hemi just like this and the same misfire that the owner couldn't figure out but it idled fine. He replaced all the plugs, coils, and injectors for a ton of money and gave up on it and I was taking a risk on trading my daily driver for it. I did a compression test and that cylinder was alittle low but it would still built like 60 psi or something. I took the valve cover off and I found one push rod had come out from under the rocker and was diagonal and the top was gently against the valve cover. I pulled the rail off, carefully inspected the rod to make sure it wasn't bent, put it back together without asking any questions and that truck ran mint until I sold it months later and still ran great. No clue how it just came out from under the rocker but it did. I know the 03s and 04s have the valve spring problem and your customer was lucky it didn't blow up the engine.

    • @JW...-oj5iw
      @JW...-oj5iw Před 5 lety +11

      If your compressed air supply is less than the time needed, there is an alternative trick. Lower the piston a bit, feed a piece of thin rope through the plug hole and raise the piston against the wad of rope. Valve is held in place while spring is replaced. When repair is complete, lower piston and pull out the rope. Hopefully, you use a long enough rope that there is plenty on the outside of the engine.

      @@JW...-oj5iw This is exactly what I would do "in the field" when compressed air wasn't available. Pretty old school trick. Always tie off the other end of the rope so you don't lose it inside the cylinder.

    I bought a new 2004 hemi pickup and in ‘06 went on a 5000 mile retirement sojourn around the US. I drove that vehicle in a spirited but conservative manner, well cared for, and near Pierre, South Dakota the #3 intake valve spring broke! Had it fixed under warranty with no problem. When I got home to Tucson I brought my “baby “ to the dealership for routine service and told the service writer that I had a broken valve spring on the sojourn, and he said “it was # 3 intake, wasn’t it?” Apparently not an uncommon occurrence, I figure!

The truck has 230,000 miles and I revved it out at least 5 times a day, glad to see another person get lucky with the draw on the spring breaking near the top and not dropping the valve.

      Exactly what I suspected. Purchasing dept. at the factory was swayed by the lowest bidder. In the purchasers defense, the management incentivizes and grades their purchasers on cost reduction. So you end up with a supplier that has/had no concept of process control. When in doubt, ship it! This is a systemic problem in American manufacturing, which is why I just bought a 1999 Toyota Camry with 266K miles. The kicker is that I benefit directly from this mentality. My father-in-law, retired at 55, gets a $2k per month pension which allows him to live independent of our help. He now suffers from dementia, probably from sucking too many paint fumes in the 70s and 80s.

He was telling me that they had a influx of bad heads on the 5.2 and 5.67 hemi's cause they where being built so cheap. The problem the exhibited was misfire at idle. The verdit that was causing this turned out to be cracked valve seats, in close proximity to the cooling passages. Which would cause weeping of coolant that would leak across the plug at idle.

    Finally drove my s-box truck yesterday! First time in 2 months. No howling or other noises back there, so I won (I'd better shut up - only 5 miles on it so far). Only issue is, OX included every air fitting, except the one to connect the line to the compressor! Looks like I'll be waiting another week for those parts to get here. At least I can drive it now, though. Going to have to run the air line from the diff up into the cab, to keep water and crap out of there in the meantime. Not a huge deal - I can still use 4x4 to get moving when it's raining, lol.

    Well… I didn’t want to think you were right hahaha. My 2007 Chrysler 300c was doing exactly this & also a new friend on Facebook. We both ordered brand new PCMs to no avail. I pulled my valve cover once but wasnt looking for a broken valve so I didn’t see a broken valve haha. I check my pushrods to see if that were all still seated. That was a month ago. Here we are today, i paid attention to which exhaust I was getting Gas & smoke smell from & it turned out to be the same side I had the valve cover open for haha. So I pulled the valve cover back off & Yup… Back intake valve is TOAST. Doesn’t look like the valve dropped, but I’ll be pulling it off tomorrow so we will see what the true damage is. I heard no noises so we may be in good shape. I’m just extremely happy it’s internal damage & I found the problem lol. I’ve been thinking it’s PCM related or wiring related because a rat infestation literally JUST happened & I found shit in my engine bay. I’ve been panicking but all rats are dead. Valve springs toast. All is well in my eyes haha. You did a GREAT diagnosis & I literally ignored you for a month until today.
