LOL, my tablet freezes from time to time and reboots watching KZbin videos. Thought that's what was happening.

[@tacocin]

As an experienced hydraulics tech I was yelling at the screen watching you test that solenoid. I knew too well that just because it clicks doesn't mean it's working properly. And then when it didn't click I was thinking mechanical failure, like a jammed plunger. I was so glad and relieved when you found that foreign object in there! What a crappy, cheapo design to use flimsy plastic parts in a critical system. ugh! I hate it when bean counters run anything!!!

[@TheRetiredtech]

But always blaming aftermarket, if oem was so good there wouldn't be such a need for aftermarket

[@TheOnespeedbiker]

@@TheRetiredtech Of course many times the parts canon isn't even necessary and then a real mechanic has to chase down the the problems cause by the AM parts. I'm seeing more and more where the parts canon has been fired, mechanics reinstalling the OEM parts just to get the vehicle back to a state were diagnostics are even possible.

[@PineHollowAutoDiagnostics]

@@TheRetiredtech in this case the OEM is also garbage 😝

[@ferrumignis]

@@TheRetiredtech OEM most always has a price premium and people continue to value price over quality. Unfortunately some OEM parts are junk too, but the chances of poor quality dramatically increases in the aftermarket.

The fix here is simple: remove existing engine, install 4.0L, never have a problem again.

[@hightttech]

If Gary Larson were to weigh in on what we just watched, perhaps he would draw a team of Jeep engineers standing around sweating and looking very nervous. All their lab coats display old, "Cadillac" embroidery crudely covered up with red Sharpie, and "JEEP VVT/VVL TEAM" handwritten underneath. The caption reads: "Bob and his team remember the '4-6-8', and the unemployment line." 😆

[@gaad7938]

I got a good laugh from your comment. My boss (many, many years ago - I'm retired now) had one of those Caddy's when they first came out. Needless to say it ran well for a (very) short time. Then he came to his senses and ditched it.

I had a car in a while back that had a gummed up solenoid as well. Turned out that there was a little piece of aluminum foil that was stuck to the mesh. I scratched my head until I did my next oil change which involved opening the oil jug removing .. the tin foil top... Aha! I made a mental note to always cut open these types of containers with my knife (before I just used to puncture with my thumb) to avoid any shards of aluminum going into the oil pan. I was a bit surprised that the oil filter didn't pick this piece up but... who knows

Do you recall what DTC you had? I currently have P0303. I confirmed it's not the coil. I also replaced both cams, lifters and rockers on that bank. I'm hoping this is my issue.

Thank you for the video!! I had a P0302 intermittent misfire, cylinder #2, 2017 Grand Cherokee. It was driving me nuts. I watched your video about a week prior. The misfire went away for about a week and came back. I pulled that solenoid today and sure enough there was a small piece of plastic in the same place. The local Chrysler dealer had 3 in stock. They wanted $188.62 but came down to $139.00. We needed the car and couldn't wait 2 or 3 days. I can't thank you enough for your video!!🙂

How hard was it to pull the solenoid ? How long did it take?

[@daverson1508]

@@cinepost Once you take off the air filter housing and air plenum (10 minutes). Solenoid is in front of spark plug #2. It takes about 30 seconds to pull the solenoid. It's bolted in with a 10mm. It took a bit to figure out the electrical connector tho. Easy peezy.

Very interesting, and very, very well done Ivan. I thought the VVL valve clicked alright in Part1 . Which of course doesn't mean it works. Again, exceptionally well done. Thanks for all you do to provide these videos. Omegaman

[@111-c7x2t]

yes it clicked just fine in part 1 and then he broke it and created a new problem

[@TheOmegaman69]

@@111-c7x2t No, I do not think he broke anything. The problem was there before he did anything. When he tested it on the bench in Part 1, it both clicked and moved and seemed to work fine. But, back on the car it failed again. I suspect the explanation is pretty simple, and also explains why the problem was intermittent. That little piece of plastic Ivan found most likely moves around a little bit, sometimes prevent the VVL from going into High Lift Mode, and sometimes (like on the bench in Part 1), it does not block/prevent the VVL from going into High Lift Mode. This explanation makes perfect sense, and could (very likely does) explain all that was going on with this VVL Valve, the misfiring Cylinder 2, and the intermittence. One other thing I thought of is that the entire time Ivan tested it on the bench it was horizontal. In the vehicle it is almost vertical, at least mostly vertical. With a good VVL Solenoid this would not matter, but with that piece of plastic bouncing around in there, this could make a difference. It could have moved such that it did not prevent the VVL Valve from working right on the bench, and then nearly vertically in the vehicle, not to mention the oil and the associated pressure, the piece of plastic could have moved to where it did prevent the VVL Valve from working right. After all, that was part of the complaint, vehicle ran good sometimes and missed other times. This is just a possibility, off the top of my head, and I am not saying this is what happened, but it is a possibility. Omegaman

Well under heat or pressure it might act differently. Something internal not acting correctly.

[@christopherbieniekbaseball3059]

Good morning Ivan Thanks for the most helpful video post yet for my 2016 Jeep Grand Cherokee. I experienced rough idle this past Sunday, and then check engine light came on. Code read P0302 misfire #2 cylinder. My first thought was ignition coil or spark plug since the truck has 78k on it. I changed those and was kicking myself for not watching your video sooner. After changing the VVT Solenoid front #2 everything was resolved another $140 later from the dealer since they only had the part in stocks. This morning, I decided to submit a vehicle complaint submitted to the National Highway Traffic Safety Administration (NHTSA). It's time these vehicle manufacturers start designing critical engine parts the right way. I think if more consumers submitted complaints, we could get more recalls added by the manufacturer. Thanks again for your help!

when I was watching your video about intermitant misfire in a 2008 Pontiac, that really didn't come to a firm diagnosis. Pretty sure I remember replacing this solinoid in my 2009 Pontac for similar problems. I trouble shot down to a couple of solinoids and a coupleof other possibilities but nothing really firm. I went and asked the dealership parts department " which one do you sell most often "It ws the valve posution solinoid you were just showing us . Replaced solinoid in my 2009 G5 and I haven't had the problem since. Troubleshooting by sales records!!!

[@boomer9900]

So when I lived in Oregon, my house outside hose would randomly loose pressure. Made for washing your truck not fun. At first I blamed the wife for running water in the house like the washing machine or something. I mean sometime full pressure, sometimes 3/4 sometimes 1/3 and random. What the heck. I got a pressure transducer (water pressure meter from target) and I was right. I hired a plumber to replace the faucet, and make him give me the old one. I used my grinder cut it open. The little screw that held in the rubber washer worked its way out and was randomizing its orientation and blocking the flow. Bonus Footage No what really takes the cake is that the screw was in the washer when I looked at it. So somebody before me who owned the house the screw fell out and they just put in another new screw in the washer and left the old one dangling around in the valve. Your video reminded me of that damn hose.

[@ccmoos]

You are so good at creating videos with serious issues!, The engine must end up with wrong mixture in the cylinder 2, and hence misfire. This type of engine will be full of problems as the mileage goes up

[@calholli]

That piece has to be from inside the solenoid, because it definitely didn't pass through that screen.

[@Sandmansa]

I must be lucky to not have had a failed VVL come through my shop yet. But if I get one, I'll know what to look for.

But anyway, good stuff Ivan.

Very clever approach to test the valve in place and, bye bye mystery! Really odd failure of a miniature plastic retainer (wonder if this was a first, or if it happened before in other cars). Modesty appart, my doubt about the solenoid valve testing OK in the bench and still failing under pressure, was somehow correct :-) Great that only the solenoid valve was required.

You may have already determined this, the plastic debris you found is part of the ball retainer. It sits between the ball and the screen.

As I see it, there are only two possibilities of where the debris could come from. 1. It is a part of the internals of the solenoid assembly 2. It is a manufacturing contamination, during assembly, possibly from the machine/robot that performs the assembly operation. That whole process is probably automated, and quality checks on a certified process would be made only on samples of the work in progress.. 3. I should have watched to the end of the video. ;)

This is what was seen in a 2003 Honda CRV. Chain had been done because it was misdiagnosed. I saw a mesh piece missing from the timing solenoid and though that maybe the solenoid was partially stuck open allowing oil pressure bypass as the time was advanced as a soon as the car was started. New solenoid fixed the problem, the other tech said he did see something inside that was stuck but I didn't see that myself.

I did not mention on my comment on the first video , about 3 weeks ago I had one in a Durango went to get a dealer solenoid and it’s on galactic back order, used a Napa one and fingers crossed it has not come back. At least it’s not like the Hemis wiping out the camshafts.

This was an AWESOME video for sure!! Thanks Ivan!!

BRILLIANT analysis & diagnosis Ivan! I was wondering where the hell that weird little yellow plastic pos came from, but you worked that out when you got to see a new solenoid! What is the actual shape of these plastic parts when they're intact?

Bruv... I like the way you think. You sound like me when I'm troubleshooting IT problems... logical and methodical diagnosis. If you and I were stuck on a deserted island I'm sure the end result would be we both survive and said island being transformed into a tropical resort. We'd get STUFF done. 😂 Great video... This was the same problem I had with my 2016-17 Jeep Grand Cherokee.

I think that little bit of plastic jammed up your video at 19.00😄 Great fix Ivan 👍

Ivan, out of curiosity, to test the solenoid could you have swapped it with one of the other ones to see if the misfire changed cylinders? Much like swapping coils, chasin a misfire.

I believe the other solenoids are quite a lot more work to get to.

YOUR VIDEO IS AWESOME, THANK YOU FOR SHARING. HELPED ME OUT TREMENDOUSLY

Imagine the amount of waste (coil packs, spark plugs, CAM/CRK sensors, Motor oil, coolant, may be the cylinder head or even worst an Engine) that could have ended up in a local dump if this Jeep didn't go to Ivan! Ivan is not just saving the customer's money, he is even saving the Environment! Thanks Ivan!

Until you figured out where the plastic piece came from I was thinking disgruntled worker at the solenoid assembly plant put it in there as a form of protest.
