Hello Ivan, this is Lester from Dorman… we don’t make/offer coil packs, we make the valve cover. Was there something else that failed or a mark on the part to lead you to think it was a Dorman?
Hey Lester! Oh haha must have been another junk aftermarket brand then sorry about throwing Dorman under the bus 😅...I'm just so used to seeing junk Dorman electrical parts causing problems that it's a reflex. However they do make great brake lines and door handles, just not electrical parts or gaskets 🙂👍
@@PineHollowAutoDiagnostics Thank you for the response… I appreciate it! No worries…Dorman and aftermarket suppliers in general have to get better at developing electrical products.
Lester, I am sorry that it is you, but I have needed someone to hurl Dorman insults at someone there for a LONG time now. It is disturbing how the Dorman brand can still stay in business. I recommend going to work for a company that makes an honest living. Or who are the next ones up the ladder there? I would like someone with whom I can practice the Captain Insano eye-poke move on. Edit: one of the many examples was a good latch cable for an old 2000 Honda Civic. The cable works fine UNTIL you have to make that final 180 degree bend like the factory original cable needs to do. It is obvious that whoever produced the cable never actually installed it on the car to test it. I ended up heating up the handle of the Dorman cable, slipping it off, and I installed it in place of the broken handle of the original cable. Dumb design by Honda, but their cable worked fine until the handle broke.
I think Dorman has a great window to step up their brand image. The window is open for a very short period of time as prices and supply are in total chaos. The idea is that Dorman realigns to offer high-quality parts via it's established excellent distribution network. Unlike 10 years ago, today, there are so many inexpensive fakes on-line these days that cheap is no longer a viable competitive strategy. So solid distribution and good reputation are how Dorman competes. We all know a lot of the Dorman parts are excellent quality and the catalog is huge but a small amount are not sourced or QCd properly. The reputation of the whole enterprise suffers from this. Step one is to remove the small number of high failure parts, step two is to find reliable substitutes for those. Step three is to step up QC.
On cars where the drop test is inconvenient to access coil packs or injector connectors (or TBI / carbureted cars!), can also use the temperature of the exhaust manifold near the cylinder head to determine which cylinders are not firing. Engine does need to be at least somewhat cool before doing this, though. The ones that heat up more slowly are the cylinders that are missing…
I have used many “hard” Dorman parts for various repairs, and sadly sometimes the only thing available,but they usually get the job done. But absolutely NO electrical components, and admittedly I learned that by doing it Myself in the past. 👍👍
Similar experience, especially in the last couple of years with shortages. I work on motorhomes, and two common failed parts I encounter that a Dorman ends up getting used on is the vacuum canister that fails on Ford motorhomes ( same with Ford E series vans ) causing the dash air gets stuck in defrost, and the Chevy fuel tank vapor charcoal canister ( same issue on Chevy vans ). I try and use OEM, but sometimes it's the difference between 1-2 days, and 1-2 months. But like you said, stuff like this is my limit on Dorman.
put Dorman exhaust manifolds on a customers 08 F150, Within 3 months both warped and cracked and I had to redo the job for free. Poor quality castings, no QC at dorman at all.
@@darrenfloen2693 I’ve used them on several older GM small blocks and had no problems. You always want to check for perfect flatness on both the manifolds and heads before installing.
Something else you might consider purchasing OEM. I got a broken windshield this week in the Marquis. I contacted my insurance company and they informed me they wouldn't pay for an OEM windshield. I went to my glass man (Whose grandfather, father and him have replaced every windshield I have ever had replaced since I have been driving; which is 40 years) and he REFUSED to replace my windshield with anything but OEM. I told him I would pay for it out of my pocket. When it came in, he compared it to a cheap aftermarket windshield and it wasn't "bent" correctly to fit the car. Now, you wouldn't think someone could screw up a piece of glass, would you? I went back to my agent and demanded to be reimbursed. They did. Great video!
I agree Dorman is sketchy at best. Even factory OEM stuff isn't always reliable now a days. That's what I love about your informational videos, you get down to the real issue and solve it. Thank you....Pete
As a quick alternate test when you have a bad misfire, check each exhaust port against the head with an infrared thermometer (or thermal camera). A dead cylinder will show a very obvious temperature difference, at least soon after starting from cold.
I recently repaired a 2015 cruze 1.8. Replaced the coils last year with aftermarket coils.bad this year. I am blaming partial clogged injectors for ruining the new one. Cleaned injectors replaced with durolast lifetime warranty. Customer happy.
These small Ecotec engines (1.8, 1.4 etc.) are super sensitive to coil packs and spark plugs. GM or AC Delco from a RELIABLE seller would be all I would consider. GM put copper plugs in some of the engines so those only last say 30k miles before the gap gets too big; that might stress and kill the coil pack. We changed to iridium plugs to reduce maintenance but there are advantages to the copper used by GM.
Someone brought me a car saying the gears have gone too high (manual car). Anyway, they gave me a ride back to my work area. I could not believe it the car was only running on 2 cylinders and they were revving the engine twice as fast for each gear change only making 3 rd gear on the Motorway. The thing was it sounded moderately normal... It was just a coil pack..
100% agree, I never use any parts on my VW/Audi engines other than the OEM Bosch stuff. I hate those coilpacks with a passion too, the individual coil on plug design is 1000x better than those 4 in one things 🤢
-Dorman- Unknown manufacturer aftermarket coil pack and Autolite plugs, ftw....NOT! Nice diagnosis, and quick. Thanks. Not a fan of that GM coil pack design.
Nice diag Ivan. I've got the same vehicle which had a miss. Ordered a gm oe coil from the parts store. Package was re-sealed. Despite my apprehension,took it home. After opening found no gm label or markings on it. Returned that to the parts store, and an additional coil was provided with gm labeling on it. Car was fixed. Buyer beware.
I liked Dorman up until a few years ago. Admittedly, I never worked on a ton of Euro and was already more prone to go OE when I did. Maybe I was just plain lucky beforehand, but one day half the Dorman parts I put in in the last month started coming back. For example, EVERY Honda VTEC spool valve assembly. I refuse to even use any of their gaskets anymore, as every spool valve gasket has turned to mush and I had two ecotec valve cover gaskets do the same. I'm sure there was more that I tried to forget about, ha. On a side note, has anyone else run into every one of their parts suppliers erroneously listing VTEC components as VVT components? Very annoying. In all honesty, haven't watched the video yet, but couldn't help responding to the comments this morning lol. Thanks for all the great content and learning, Ivan!
The other day I replaced a blower motor and a resistor that a coworker diagnosed. Got it all connected up and still didn’t work. The ground was fine from the resistor connector to the chassis. But when everything plugged in it would not supply ground to the blower motor. Something in the Dorman resistor wasn’t passing the ground on to the blower motor. Got a new non Dorman resistor plugged it in and it worked as it should.
2 things. 1st you must use the proper and updated Delco plugs in GM vehicles. GM updates these (quietly) all the time, so a call to your local Chevy dealer to just ask what plug number they have for your XYZ is worth it! 2ndly, I've tried nearly ALL of the aftermarket partshouse coil assemblies available for this engine series and either they flat out don't work, or fail rather quickly. Sometimes you gotta bite the bullet and buy the OE. As for scan data, 100% agree, scan then verify.
I bought a used car, and I used the parts cannon on it (two problems still there). However, _every part_ I replaced was one that I personally considered reasonable to replace due to it being a 14 year old car. Gaskets, hoses, spark plugs, multi-fuel/oxygen sensor, etc.
I know those chevy cruze all too well. I had quite a few of them with bad turbo's and it's almost always a clogged oil feed tube that does them in. It's so close to the exhaust manifold that it can and will cook the oil inside of it. I can't see it clearly in the video. But it looks like that tube on the top of the turbo is the old one. Ivan, can you reach out to the owner and ask him about it?
Check the head lights. GM usually have at least 1 head light out. Watch next time you drive anywhere. I cannot leave my house without seeing several GM products with a head light out. Ivan let me know if the head lights work.
@@Runco990 Really? In 55 years of owning Ford cars and trucks, I've never had to replace a tail light. But, anything to take a cheap shot at Ford - right?
I drive around a lot for work and the non-working lights I notice most are the outside brake lights on 5th generation Hyundai Sonatas and Elantras. Maybe it's confirmation bias.
Yeah I noticed that. No wonder the turbo blew up, cruising around on 2 cylinders there were probably times when fuel was combusting inside the turbo...
Imagine what would happen if doorman had legitimate quality control and just quality assurance, they would easily be a leading aftermarket parts manufacturer
When you spend a few hundred on a fancy intake and valve cover but you cheap out on the basics. Separately I would leave more lead on that MAF connector, that looks a bit too tight. I'm worried that with engine vibration and natural movement it might pull the wires out because there isn't much strain relief.
It makes sense why the scan shows as good. It's measuring the pulses to the coils, but if the coil itself is bad, the way Suzuki (?) set the engine up, there's not enough data in other sensors to infer the coil pack is bad. So yes, pull a plug wire (if possible) to do a reality check.
people swap these coils all the time for nothing. I own a cruze - also notice tons of aftermarket kits like air cooler etc. Usually the more significant problem with these are it's weak pcv system including cam cover and the root cause shitty intake manifold with integrated check valve. Also intercooler piping have lots of leaks at the seams and sometimes at the throttlebody.
More likely the PCM wasn't even detecting it to begin with. I'm not inclined to blame the scan tool on this one. Or maybe the defective coils where arcing internally.
Just becouse of your channel i got an 4ch osciloscope - chip chinase crap hanatek but it will do for DIY automotive stuff. Channel count is waht i wanted - now learning how to use it.
87 000 miles and a blown turbo...speaks to how unreliable turbo engines can be. My Sprinter work van needed a turbo at 103 000 kms or 62 000 miles. Turbos are great when they work but when one fails...oh boy. The quality of after market Chinese parts is just awful. I deliberately buy MADE IN JAPAN/USA/CANADA whenever possible. Made in Japan is still hard to beat overall. USA is also real good. You pay people a good wage and generally you get a good product.
Running on 2 cylinders long enough to discolor the manifold I'm sure this turbo was tortured... Probably had combustion occuring in it at times severely overheating it. Turbo failures are not that common at lower mileage, it's usually abuse that takes them out (lack of maintenance, or in this case probably driving the car for a really long time with 2 cylinders down, and who knows what their oil changes are like.
Aftermarket car parts are a minefield. Forget buying name brands from eBay or Amazon, lost count how many counterfeit Bosch or OEM parts I've bought over the years that either don't work or fail prematurely. Stick to main dealer or trusted local suppliers for your parts.
I can see why you would jump to the Dorman/junk conclusion. Those of us that have trusted them more than a few times have been burned. Seems like even though they may make changes to a part in an effort to solve OEM manufacturer issues, they fail in some other way or only last a short time because of their own quality issues. If Dorman wants to improve their image, they need to make a real effort.
It feels smooth due to the 2 good cylinders having their companion cylinders dead, does this engine have a cylinder kill system LOL? I also take this fact into consideration when I want to test a good cylinder for other tests, kill a spark, kill an injector, or test a good in-cylinder waveform, I always TRY to kill the known good opposite the known bad, its companion. This will assist in keeping a smoother idle speed and helps to smooth out the waveform on the scope, try it, you will like it. Thanks for the tip on DONT TRUST your scan data. A scope doesn't lie, a scanner can fool the FOOL.
Interesting vid .. once again crappy non OEM new parts no good. Makes you wonder how it idled so smoothly the correct two cylinders in the firing order must have failed to give a smoother operation The fuel trims must have been pegged lean as well with two none firing cylinders pushing unburned fuel into the exhaust system but still idled ok . Goes to show you things don't always behave as you would expect.
As a gm tech, I cringe every time I see a shiny black ignition coil on these 1.4L engines. The epoxy on the oem ones is tan. The oem ones go bad enough, but I’ve seen these dorman ones go bad right away, and cause weird issues that are hard to diagnose. One vehicle kept dying on the customer and would not restart. He had it towed in several times and every time I looked at it, it ran and drove just fine. Ended up being a dorman coil pack. Since then I always check for oem coil right away.
Saab 2.0 and 2.3 engines were also very picky about ignition casettes, aftermarket junk would only last a month or two and start misfiring. Only option was to go genuine OEM part that lasted for quite a long time.
Yeah those T7 units worked hard in a difficult work environment. If you bought after market, the cash savings were wasted because you had to buy 2 lol. At least Saab were kind enough to give you the tool to change them on the side of the road. I only ever had 1 unit fail on me....as I pulled into my garage after a trip.
A little off subject// I have been using Autel,following you channel I see you use the Thinktool pro, how is it for updates and is it supported in USA or China?
Where is that misfire scan data coming from? The ECU is recording that data incorrectly right? The scan tool is probably just displaying what the ECU has stored
I wonder why it's not detecting a misfire on Cyl #1. My understanding is that looks for "contribution" via the crankshaft sensor. Perhaps something is contributing just enough somehow?
I have used a simple resistance measurement of the coil windings to determine a intermittent problem with my V6 wasted spark system. Can the resistances be measured in that coil package ?
It's all a crap shoot these days even with OEM. I replaced the original timing belt on a Kia soul at 110,000 km with a complete Aisin kit. 40,000 later the tensioner pulley bearing siezed and created quite a mess. Seems that Aisin kind of gathers different parts of their kits from different suppliers so not doing that again. The original Kia timing belt and tensioner were clearly marked Gate's. Ivan, I remembered the video you made where the Gates parts you ordered were not up to parr and you called Gate's about it. With that in mind I couldn't bring myself to order a replacement Gate's kit either so I got all Kia OEM parts even though the Kia belt alone cost more than the entire Gate's kit including the water pump. When the Kia OEM belt came it was clearly marked Gate's made in china!!!!! and was visibly of lower quality than the 110,000 km original Gate's belt.
Just because it's doesn't mean it works..I would have got this from you pull and pay...before Dorman..he has that lifetime warranty...just go exchange it and hope it works..
Assume they are all the same so you race to the bottom on your parts, if you walk into the place down the street that may be all they have. People who watch this I suspect go online and get OEM or higher end parts, you watch the parts on this show that don't work out of the box or pass the 5000 mile test.
HI IVAN ,well being from California,i would say that's perfectly NORMAL.It's the NEW laws that went into effect for greenhouse emissions and the governments way of moving you to ELECTRIC cars. EVEN YOU. as one of the best in the industry SAID :it runs smooth" Being that traffic here is usually only25 mph on our freeways,no-one NEEDS more than 2 cylinders anyways.haha They went from 8 to 6 to 4 and soon to come 2.Whatever they use in CHINA,that's the model.haha Your vids lately have really been good,the harder the issue the more we learn from you.,thanks ivan

This will assist in keeping a smoother idle speed and helps to smooth out the waveform on the scope, try it, you will like it. Thanks for the tip on DONT TRUST your scan data. A scope doesn't lie, a scanner can fool the FOOL.
Thanks Ivan!
Interesting vid .. once again crappy non OEM new parts no good. Makes you wonder how it idled so smoothly the correct two cylinders in the firing order must have failed to give a smoother operation The fuel trims must have been pegged lean as well with two none firing cylinders pushing unburned fuel into the exhaust system but still idled ok . Goes to show you things don't always behave as you would expect.
SAAB used a knock detection system that was tied to the plugs but I don't know if that technology was used in this engine.
Short and Good information
50/50 % Dorman;very Good or very bad.. very good diagnostic.
I think it’s the white stick on trim on the dash that interferes with the ECM.
Seriously, how does Dorman stay in business? You would think that by now their reputation would've ruined them
Too big to fail lol
Always oem parts people Always oem...this is the first thing ivan always emphasise.
I’m using the WPS in the exhaust to verify exhaust pulses and see exactly what cylinders are misfiring
As a gm tech, I cringe every time I see a shiny black ignition coil on these 1.4L engines. The epoxy on the oem ones is tan. The oem ones go bad enough, but I’ve seen these dorman ones go bad right away, and cause weird issues that are hard to diagnose. One vehicle kept dying on the customer and would not restart. He had it towed in several times and every time I looked at it, it ran and drove just fine. Ended up being a dorman coil pack. Since then I always check for oem coil right away.
Saab 2.0 and 2.3 engines were also very picky about ignition casettes, aftermarket junk would only last a month or two and start misfiring. Only option was to go genuine OEM part that lasted for quite a long time.
Yeah those T7 units worked hard in a difficult work environment. If you bought after market, the cash savings were wasted because you had to buy 2 lol. At least Saab were kind enough to give you the tool to change them on the side of the road.
I only ever had 1 unit fail on me....as I pulled into my garage after a trip.
Its maybe suffering from cylinder wash causing the crank signal speed to not be picked up as a misfire for no1
I'm surprised they spent the money on the ZZP Intake but not the ACDelco coil pack, haha.
_FMG_
I bought a ZZP coil pack and I’m now having the same issue as in the video
A little off subject// I have been using Autel,following you channel I see you use the Thinktool pro, how is it for updates and is it supported in USA or China?
Where is that misfire scan data coming from? The ECU is recording that data incorrectly right? The scan tool is probably just displaying what the ECU has stored
Brought to you by... The Moneywaster by Dorman.
I know, its not really a Dorman part but... 😂
People, stop listening to Scotty…… Like Ivan said, buy OE parts.
Question is; which is worth more?
1 Trailer house
2 Chevy pos?
It would have been even more weird if it was the spark plugs that were bad. Like the gap not checked before install so they were shorted.
another brilliant diagnostic. Maybe you should increase your fee?
Thinking you like dorman quality products.
Sometimes the cheap coil fires but not to oem specs
Well, Dorman are shit!!! Never ever works in electrical parts. Great video! Great test on scope and scanner.
Ivan, How about the balance test as a quick check on the cylinders?
I've seen that done with Ford's. Does GM support that function as well?
I wonder why it's not detecting a misfire on Cyl #1. My understanding is that looks for "contribution" via the crankshaft sensor. Perhaps something is contributing just enough somehow?
Great question!
Hi Ivan, I assume that after a new coil pack, the problem was fixed?
I have used a simple resistance measurement of the coil windings to determine a intermittent problem with my V6 wasted spark system. Can the resistances be measured in that coil package ?
Not on this one
It's all a crap shoot these days even with OEM. I replaced the original timing belt on a Kia soul at 110,000 km with a complete Aisin kit. 40,000 later the tensioner pulley bearing siezed and created quite a mess.
Seems that Aisin kind of gathers different parts of their kits from different suppliers so not doing that again. The original Kia timing belt and tensioner were clearly marked Gate's. Ivan, I remembered the video you made where the Gates parts you ordered were not up to parr and you called Gate's about it. With that in mind I couldn't bring myself to order a replacement Gate's kit either so I got all Kia OEM parts even though the Kia belt alone cost more than the entire Gate's kit including the water pump.
When the Kia OEM belt came it was clearly marked Gate's made in china!!!!! and was visibly of lower quality than the 110,000 km original Gate's belt.
Try Continental kit next time 👍
Can’t imagine buying that brand of electronic anything
The DORMAN "Moneywast-R" product line should be on the market for parts that teach the buyer at a reasonable price to buy OEM.
Chevrolet cylinder deactivation system never works well.
Strange, when a high price OEM part fails it's called one bad part, but when an aftermarket part fails like Dorman, it's all junk..........
Thanks
I was Jonesin' for some Bonus Footage
No bonus footage ???
Regardless of whose part it is, the more you buy garbage the more garbage will wash up on our shores.
Hopefully he kept the original coil pack/
That engine looks familiar. LOL BTW The car emailed you about was dropped off. . I will let you know what I found.
Awesome
Thats odd, do those center bolts have to be earthing the coil packs, or is it done via the harness.
I would not trust eather lol.
Probably a waste spark setup, 2 coils. Each running 2 plugs (the other plug is ground).
There's no way that's a misfire the car sounds too smooth I think it might be maybe a clogged exhaust or something boy the noise anyway
Dorman is the same as generic canned foods......some are ok but most are not
👍
Just because it's doesn't mean it works..I would have got this from you pull and pay...before Dorman..he has that lifetime warranty...just go exchange it and hope it works..
Assume they are all the same so you race to the bottom on your parts, if you walk into the place down the street that may be all they have. People who watch this I suspect go online and get OEM or higher end parts, you watch the parts on this show that don't work out of the box or pass the 5000 mile test.
HI IVAN ,well being from California,i would say that's perfectly NORMAL.It's the NEW laws that went into effect for greenhouse emissions and the governments way of moving you to ELECTRIC cars.
EVEN YOU. as one of the best in the industry SAID :it runs smooth" Being that traffic here is usually only25 mph on our freeways,no-one NEEDS more than 2 cylinders anyways.haha They went from 8 to 6 to 4 and soon to come 2.Whatever they use in CHINA,that's the model.haha Your vids lately have really been good,the harder the issue the more we learn from you.,thanks ivan
You and Eric know Dorman's parts are crap Ivan.
Mostly, though they seem to make a few decent parts.
