I love his videos ... since I own 2 06 Daytona's with hemi's .. one has the infamous "hemi tick" ... been watching for awhile and have learns ALOT about the Hemi

Our 2017 Ram 1500 was running fine until last Sunday. We were on the highway doing about 70mph for around an hour all was well. Once we pulled off the highway and stopped to make a right turn at the light. The truck was shaking so badly and missing, we thought it was going to stall. We drove for about another mile to where I could get out and check under the hood. Oil pressure was normal, water temp was normal. No hot smells around the engine, oil levels were normal. Went to restart the engine and it sounded like we didn't have any oil on the right side of the engine. We had to drive for another 40 minutes on the highway to get home. It never got worse but it sounded bad. The missing and knocking sounds sometimes go away and it sounds normal. I am thinking it might be a bad cam and lifters, but it shouldn't go away and come back. Crazy it was running great until we came to a stop.

What did it end up being

He's got 2 or 3 videos of cam/lifter R&R on this page. And Hemis are all basically the same process. So a cam/lifter R&R in a 5.7 Challenger will be about the same as in a 5.7 truck

Thanks for watching Greg!

right?

i had a misfire on an 02 altima, swapped coils, spark plugs, misfire stayed on the same cylinder. ended up being a fuel injector that lost its o-ring😒

What was it ?

Head gasket.

Vacuum leaks

Mine is doing this did you find out what causes it? I have no codes new plugs checked all coils and injectors

This is true, but unless the lobe is very badly damaged it can be tough to tell if one is not moving as much as the others. 👍

Oh, 2007 Aspen

Got a video for you right here! kzfaq.info/get/bejne/mbJjq7GgsNmddWg.html 👍

It's not usually visibly loose, however you will be able to see that the rocker arm does not push down as far as all the rest of them do.

It's possible but very unlikely unless the vehicle has sat for a very long time, or if you have reason to suspect you got contaminated fuel, but that usually shows up in more than one cylinder. It's a fairly easy test to swap the injector to a different cylinder and see if the misfire follows it. 👍

Same boat. Did you ever get it fixed?

Is it a constant misfire, or does it happen more at idle, or more so under load?

So dielectric grase is not needed for the coil pack boots?

SHIT! I just did my plugs and used dielectric grease on all of them! Wish I had read your comment before. That’s what I get for watching other people’s videos.

@@thomydavidHahaha. Its an easy mistake to make! Dielectric grease is typically used for Vehicles that are prone to get soaked in water such as boats, ATVs and Dirtbikes. On cars, it creates an issue if you put it on your spark plugs or where the coil pack meets the spark plug. It can also create a hell of a time for you to get them back off in the future since the dielectric grease dries up and makes your parts stick together. Ever since i found this out, ive never used it again. Havent had any misfire issues, and if I need to yank my coil packs out, they come out without a single issue. My next thing to wonder is if you can put a small glaze of anti seize on the outside of the coilpack boot, where it sits into its bore. Seems like a logical idea but I havent had an issue removing my coil packs since I got all the Dielectric grease out of there. But yup! it all just dries up and creates gunk into the coil pack boot. There was alot of green gum in there afterwards. I had to buy new boots.

@@BWADaniel thanks for the reply. Right after reading your comment I went and yanked all of my coils/boots out and cleaned them with q-tips and then cleaned all 16 brand new $180 worth of spark plugs. I wanted to eliminate that possibility as potential problem for diagnostic purposes. Turns out I’ve got lifter failure and worn lobe on my camshaft which sucks. But, I did leave some of the dielectric grease on the same spot you just mentioned just to keep any moisture getting in. Thanks for the tip. I really appreciated it.

@@thomydavid What year is your car?? You have the Non-VVT engine or the VVT one?

You've swapped the engine and the PCM and you're still having a misfire on the same cylinder? If so, at that point you've already narrowed it down to the wiring harness. Either the injector wiring or the coil wiring is compromised.

That's the weird thing we've checked that before spending all the money we did. How would you test it just so I can make myself feel better I'd try anything. It's a multiple cylinder misfire but number 6 is the pissed off one. Seems nonsensical. And on this engine only seems to do it on cold start and you try to immediately drive it. And there's a code for wrong viscosity of oil but it's correct and just a break in oil. Bunch of weird things. Sorry but I'm desperate. Any help is appreciated

Yes, there is a difference in the block and crank of the pre and post eagle engines, the oil pans will interchange, but you don't want to try mixing blocks.

@@ReignitedAuto ok perfect, that's all I needed to know. Thank you 👍😃

That's correct, switch both plugs at the same time to another cylinder.

@@ReignitedAuto thank you for the reply .. hasn't acted up since but don't want to chance it

If it's that intermittent then I think it's probably just fine.

2012 ram 1500 5.7

I'm not going to say no, but it would be extraordinarily rare.

You could, but really the difference in the results generally ends up being fairly minor. And truthfully the actual number isn't that critical, it's more checking whether it's consistent with the other cylinders. Or if it's below 100psi overall. Also, if you do this you'd better make sure the engine doesn't somehow fire up, it'll go full throttle 😄

Could’ve been numerous things. Even a failing Crank or Cam position sensor, would’ve caused those symptoms. The symptoms are almost never the same, some are bad, some are very bad lol. Sucks that you sold it, but you never know, maybe the car would’ve ended up with thousands of dollars of work needing to be done like mine lol. I’ve got the 07 300c as well, and I just became a master mechanic working on my shit hahaha. Rebuilt the engine and replaced a few things on the inside of the trans. They are good cars when they run lol.

You could’ve even had a failing fuel pump that starts to sputter as it gets hot. It’s rare that it’ll do that instead of failing, but everything’s been seen lol.

Yea I wish I wouldn't have sold it either but I've got 2 05s a dodge magnum an a 300c. I had just kinda gave up hope on the other one after I crossed that invisible line as far as money suck into it. Thanks for the info though. Any information I can add to the data bank is good with me. 🤘

@@BWADaniel I just had a chance to get that car back my buddy who bought it didn't attempt to do anything with so I figured I'd make him an offer. I've got a new crank sensor an a cam sensor for it. Not installed yet. I just keep thinking about one thing. Could failing lifters cause that issue. Imma get the car back regardless. I was just curious on someone elses input. Thanks in advance.

@@BWADaniel okay not a mechanic and also a female first of all lol but my car 07 300c 5.7 just started this, plugs r good. Had a misfire on cyl 7 but switched the pack with another and no misfire code any more so I was like okay but now its running the same and pulling P1417 is cant find anything much on it that is current...2 different mechanic friends said to try the cam shaft sensor...will that work?

Is it code 3449? If so, first place I would be looking is at the wiring harness going to the MDS solenoids under the intake manifold. If you've got faulty wiring or a stuck MDS solenoid it could be misfiring due to that. It's someplace to look anyway. 👍

@@ReignitedAuto it showing the p3439 cylinder 5 exhaust valve control low. I changed the vvt solenoid. Thank so much for IL try that next.

Definitely watch this video first 👍 kzfaq.info/get/bejne/oLOqnLCivLixm2Q.html

Thank you brother for answering my question

Hey for you info the map sensor wire connection not tight will throw the code for the lightning bolts between the ()

I was miss informed about the torque I did mine at 9 lbs

05 heads will fit on a 03 block, basically the cylinder head design is the same from 03-08 however, there could be minor differences in the heads themselves depending on what application they were used for. What I mean is, if you try to put truck heads on a car block, the heads will not be drilled and tapped for mounting the power steering pump. The bosses are there if you want to drill and tap them yourself, but just something to look out for.

@@ReignitedAuto thank you so much that’s what I was thinking and I think you said it before it a video but wanted to be 100% I couldn’t find it it’s very unclear online when you’re buying them if it says it’s for a 03 it seems like it cost way more I gotta 03 dodge 1500 5.7 no Cadillac converter 175 thermostat 04 radiator and rebuilt it with help from you after I get heads I have long tub headers and a full 04 SRT exhaust do you think a carb intake will fit nicely or have you seen one on a truck I’d really like a carb and cam then boost

I just finished tonight and can’t use it

This is just one thing, but on vehicles that have had a misfire for a long time, the fuel trim can be way off. Essentially it's flooding that bank with fuel it doesn't need. To correct this you'll either need to go to a dealer or a shop with an expensive scan tool and they can reset the fuel trims back to stock. This might help anyway. 👍
