thought it was cool the boy covered his baby brother's ears and not his own. family is everything.
I don’t know where you came from Hecktor but I’m losing sleep from watching your videos! They’re too good! Can’t stop learning.
After struggling with taking those Honda 2.4 valve covers off, I started unbolting the power steering pump to make things easier. Then a former Acura tech told me just to unbolt the hose from the pump. Goes from a 30 minute struggle to squeeze that cover out to 30 seconds taking a bolt off.
DUDE! I had a 303 misfire, my CRV wouldn't idle - I replaced plugs and coils, no dice - then I saw this video - "I like to take the front cover off too because rodents build nests under there" SURE ENOUGH, a nest and chewed wires on 1 injector that must have started shorting - a little electrical tape, a dryer sheet put in there and I'm back in business baby! Thanks!
Very professional at your craft, makes me proud being a technician.
Really enjoy how in each video you explain what you are doing, even if there is repetition
Manuel Salvatierra repetition is key 😎 thanks for subscribing 👍🏼
Id K if it's just me.. But I get hype when I hear that HECTOOOOOR!! Thanx 4 sharing bro.
Hektor, remember that this engine has mechanical valves. It probably needs a valve lash adjustment.
Absolutely!! These engines can burn valves if valve lash is neglected.
Good job man, diag was good. Funny how you say everything is straight-forward. That's how it is when you've been doing it for long enough. If it was me doing it it'd be sideways and backwards.
Man these are the Realest videos on youtube out of everybody that's actually competent and accurate at diag .
You make it look easy dude! I need to add 4 grommets and a valve cover gasket to my 8th gen si. I have the NGK laser plugs in my car and they work amazing. Gonna paint the valve cover and redo a lot of stuff soon.
Hector, your thought process was right on, need to hook up the scanner to check for codes or pending codes.
Since you found none, you did the next logical thing which was a good visual inspection, right on you
Located the problem! Most guys wish they were as good as you!
Me; 30 year tech, all ase's, ca smog licensed 30 years, dealer and Indy shop expirience.
Hey man. ..you being a guy with about a lifetime worth of experience of the auto industry. I gotta question or two if you don't care, I figure your the guy to ask hehe
What's the best way to go as far as pay, promotions, and longevity and easier to work at , basically provide the best quality of life for the long run. ..independent shops? Dealerships? Or trying to start your own business?
What's your take on all that, especially taking into consideration the direction the industry is going, same direction is been going for a loooong time, more tech, more electric, more hybrid, more different system designs more often. ..
What's way would you go if you, knowing all you know now, were to start off again today. ..?
TheCoatneyadkins -most money I've made was working for dealerships, 90,000 a year for about 4 years in a
Row. Rest of the years 55, 000 to 68,000 avg. yearly. Allowed me to buy my house etc...
If you work for dealership you can get so good that you beat the book times easily.
Same type of cars day in and day out so you get pretty good and fast. I was a tune up/drivability, smog licensed
Tech here in SoCal. Sure you can have slow days especially in winter. But it averages out.
Dealerships also send you to school while paying you to update on the latest technology.
Warranty work doesn't pay that great but again when you do enough warranty work you can get fast
With that also. So basically a new guy would benefit in my opinion from dealership experience because
You can really learn a lot and get your feet wet, then in time venture out to Indy shops or even your own
Business. At least that was my experience, good luck.
@@aros007z thanks for the advice, I've worked at a few different independent shops since I quit driving a truck and started turning wrenches several years ago, so I'm not "brand" new to the industry, but I have never worked at a dealer. ...I've been noticing that alot of these independent shops just simply won't pay a wrench what he's worth, wether he can wrench good and at a good pace AND diag accurately or not. And they don't care if you got all ases or none. ..or even a ged for that matter, and no drug test, some will offer to pay under the table to avoid cold support...I mean literally an unsolicited offer right out of the gate in the hiring process.....all that crap so they don't have to feel bad about not paying you a decent wage for a job that actually requires a high level of skill and knowledge to be good at. I am going to a dealership soon!
The place I work at now opened my eyes up about these independent shops, they can be really greedy.
Great video.
Its fun to watch you diagnos...
Buenísimo! Glad to see you growing & doing well Hector!
Cuba's Automotive 🙏🏼 it’s picking up 🙌🏼
Your an amazing teacher.
Im here in guatemala city.
God bless you and your family!
Great camerawork and editing. Love the video :-)
Krille's Garage Thanks, I try my best 👍🏼
That's a damn good tip about the bad diode throwing off other a/c signals. ...
Always good videos bro. I love me some Hondas and Yotas ❤️ Stay up Homie!
You doing great job brother may god give you more Success
Khan Baba appreciate that
Just found your channel and I really enjoy your videos. Keep it up buddy!
Turbopickle thanks, appreciate that 🙏🏼
Sorry to tell you, you probably did not fix the oil leaking in the spark plug tubes, it is usually the bottom of the tube loosened at the head , unscrew & teflon tape and retighten. Oil in the tube will loosen the plug, causing misfires and blow by when the plug loosens. If you check what you did it in a few weeks and you will find oil on the coil pack shaft and down on the spark plug.Also if you pull the power steering brackets that hose can move out of the way and gives you room to gate the valve cover on/off without pulling the big bracket. And yes you should check the valve clearances over 120,000 miles , you’ll normally find the intakes in spec on just a little loose (usually don’t have to adjust those,unless it sounds like a sewing machine) but exhaust valves will be tight and need to adjust.
I also look at things like ect on the freeze frame to see if it's happening when cold. Head gasket was my first thought. When the plugs get loose it will arc against the tube and also you get exhaust heat coming up from the cylinder. That's 2 things that will mess up the rubber on the coil pack and tube seal.
I hate the time change great job happy thanksgiving young man
Danny Hubert Likewise 🤙🏼
Very good detail
Damn bro I enjoy watching ur vids and learning more each time. When is the next a day in the shop video going to come out ?
Maestro Hector un gran saludo. Desde Mesa Arizona, great Job,
Good Video. The gaskets you pushed away, were for the coil packs. Would have double checked valve lash while it was open. Oh and the comment about the alternator, may just be my issue on my Element.
That whine could be the power steering pump cavitation from bad o rings.
Great job love the video
Brought back memories when I was working at stoney
Great crv series i luv these trucks
My partners car just stalled out and wouldn't turn on, every thing we did lead us too a bad fuel pump, my mate told me to spray wd40 in the air intake and if it starts it's definitely the fuel pump. It didn't start, I got new spark plugs put them in and boom she started right up
Pretty sure the spark plug came loose to cause the issue. Burnt up oil all over the plug from the spark plug tube seal. If a plug is left loose or came loose pressure from the combustion made it into the tube and burnt up the tube seal and allowed oil into the spark plug tube taking out the coil. Another possibility is a pcv system issue. Check the air filter for oily residue on the throttle body side of the filter if present the pcv valve could be sticking open intermittently.
Nice work brother. Great video
"O'right! Like that!" Classic bro.
You have a great show I was wondering if you could show more about the scope and meter set up on your Verus
Had the same issue on a 2006 CR-V. Did you check the valve lash clearances? When hot, the valve clearances, especially the exhaust tighten up and could cause the misfire. I performed the valve lash clearance on all intake and exhaust lifters using feeler gauges and drove the car around to get the oil circulating. No more misfire when the engine is at operating temperature. Hope this helps.
Great job my man...helped me do the job right...
Your intro is pretty funny, subscribed
Tony Jung Ha! thanks bro 🤙🏼
Since you had the cover, dale una lmpiadita man.... good video.
hello there, since ur taking off the valve cover, should inspect the valves and see if their within spec. also you for got to put some hondabond on 4 corners of the valve cover gastket...that will cause oil to leak on the side... i hope this helps =-)
My man hektor. Let's go
Always 👍
17:49 The additional rubber rings (seals) are for the coils. Opposite end from where the coil connects to the spark plug, under the top connector....the rubber seal is changeable.
What’s up hektor...new to your channel but love the content bro...just wanted to ask you bro..what’s a good scan tool that you recommend? I mean one that does resets, codes, actuation tests, live data and reads srs, trans, engine and abs? Any suggestions? Thanks and keep up the good work bro!
Dude never use wd40 on rubber it will eat it away never use petroleum based products on rubber. Love your content brother great job
That doesn't make sense. Oil and grease are petroleum.
Hey Hektor, nice work and many blessing. Really enjoy watching your work. I got a question, does a code p2646 cause a p301 to show as well?
It’s awesome how you interpret the data especially at 3:30. I’m currently having a misfire and my long term fuel trim is -.78% and my short term fuel trim is 4.69%. Vehicle speed was 47 mph. Does that point to anything?
New subscriber just started watching your videos great on videos. I saw and observed some of your thinking pattern on diagnostics trouble shooting. You might like see South main auto his diagnostics of figuring out that hard to find issue is good. Like your thinking on issues . continue the videos I enjoy and always move forward on learning.
Eric is the homie, tell him I said what’s up when you see him 😎
Plugs and coils prolly..but only experience Ive had with sporadic things on a vehicle (idle, gagues acting weird, hard starting) was related to computer going bad.
@Homie Hektor Hey, i'm having problem with my car only runs rough when warmed up. If I turn on the heat it will run rough rpm's will drop a little and go back same if I turn the wheel or do windows up or down yesterday it was really bad for a second i was sitting in a parking lot reading a text had interior lights on the car ran really rough and lights went out for a second like it wanted to stall. When I drive it runs great only happens when in park or at a light in drive. Here is a list of things I changed on the car: alternator, spark plugs, coils, battery, got the timing chain and timing done, cleaned the 02 sensors, cleaned the throttle body, new MAF sensor, new crankshaft and camshaft sensors, new valve gasket, checked all the wiring and grounds that i know of, changed the oil and filter, changed cabin and air filter, no codes are showing at all, changed PCV valve, checked for vacuum leaks. I think that's all I did. Been trying to find this problem for months no luck. If you can help would be great. Thanks (2 codes came up under ABS right now not sure if this can be my problem u140e and c2202) it's a Dodge Caliber 2009
What was the MAP sensor reading at idle (operating temp). should be .9, if not might want to try a valve adjustment. Also this year is known for piston ring failure...
Low compression in couple cylinders can cause that. Alot of people dont ever change the oil and causes compression issues over 100k
I have a 1998 chevy s10 v6 that misfires alot in the morning when its warmed up and the engine light started to flsah what could be the problem?
Recommend shocks and struts cmon bro the Firestone way😂 just playing I work for them also
Good Job. Because spark plug #4 was loose, hot combustion gases were leaking into the spark tube, this caused the spark plug tube seal to crack and leak, also all the damage to the ignition coil. At the end of the day the car is fixed.
I like to see your kids in the vids. Makes it real.
I noticed my 2017 civic si has the same issue but it only happens during open loop too. It happened with the stock plugs and wrong model plugs.
I'm a line tech at Honda. We see this all the time. From blow by. Needs piston rings or it will just happen again.
What it sounds like to me
Josh Kuchinski we’ll keep an eye on it, thanks for watching 👍🏼
At around what mileage do see this ring issue?
@@autoxpert5231 around 100k but honestly it can happen whenever. Usually not under that though
intermid faults are usually a pain i usually find that vibration and heat causes them
Leaking engine oil on the slark plug tube is bad for honda, it gaves many misfire codes, like mine it gave me P1339 with flashing check engine light, but the car was running fine no misfire symtomps, even that i went quickly to find a parkjng and next day i start inspecting ignition system.starting with distributor, and then removing spark plug and i find the cylinder number two spark plug covered with oil, i changed the valve cover gasket and tubes seals, and i crank the engine witj no spark plug inside to mak sure no engine oil leaking inside the spark plug tubes and then inatall new spark plugs even the old ones were new like one month old, and no more flashing check engine light.
You have the verus. Why don't you use the ocillscope to check the Ac diodes on the alternator. I think its under the main screen. Go to guide component test and I think under in one of the menu it should have something to check the ac diodes on the alternator
You're lucky, I wish I had kid's.
I pull the coils out. see if there is oil seal leaking...As I get cars all the time. Where the valve cover seals leak into the plug well.. And it gives you random misfires...
Great video I was curious how much was put towards parts
Watching this video 10 months later but hope you see my message, to check if the winning noise just disconnected the alternator connector and if noise goes away you found your problem if not it's going to be more then likely your power steering pump idk what else it would be after that besides just another pully
That’s right 👍🏼 I have a video on that too
👉🏼 ruclips.net/video/SlGJsT4DB2A/видео.html
@@HomieHektor 😂😂ok bet I'll watch it later I need sleep, quarantine got my sleep schedule messed up, love your vidz brother your a natural
Can you diagnose a p1009 even though the oil control valve has been replaced it still getting that cold on a 2004 Honda Accord 2.4 l
Aye homie hektor what kind of snap on scan tool do you have?
insaneivan100 Snap-On Verus
Run the SUV full WOT and you will get the misfire. It's most likely the sparks or coils. Same problem I had on my Honda. Mine turned out to be the coils not the spark plugs. I know it's an old video but oh well.
👍🏼
I wonder if #4 plug was loose letting hot gas bake the tube area and boot.
Homie since the plug was loose it looks like cylinder carbon leaking past the spark plug threads
Enjoy your channel vato 😎🤠
Mike Abasolo thats called a Corona stain, google bro
Hey hektor estan chingones tus videos en que parte de USA bibes tengo 2 carros que nesesitan mantenimiento 😎😎
Eduardo Morales estoy en California
🌴🌤
Is it just me or is that power steering reservoir way over filled! :-) Good video!
Hector mys throw code at cold start up only !! and throw misfire Cycle 5 code but if I shut it off and restart it same moment code goes away and idle perfect .. car has new plugs and coils n vavle cover gasket all parts oEm dealer parts replacement .
So, this is the best video I've seen by far. I need to know what it would be in my case, I have the misfires p0300, p0301, p0303 even after changing plugs and coils. I have a 2004 Honda like this one. It has 198, and change miles on it. I need to know what this is.
Laura you might have a valve adjustment issue, the good thing is that no parts are needed to fix that, it’s all labor 👍🏼
@@HomieHektor So, dumb it down for me. What do I need to tell someone working on this for me? What do I need them to do? This is my only car and with two kids I need it to work til I get a new one, ya know?
Laura ask for a Valve Adjustment, your valve cover will have to be removed and all the valves will be checked and adjusted if needed. You may need a new valve cover gasket also to prevent leaks in the future.
@@HomieHektor I will have to see who can do this, thank you. I have also located a valve cover gasket set.
Laura Awesome, let me know how it goes 👍🏼
Hey bro I got a p303 went ahead and changed the plugs and rearranged the coils cleared the code ran the car and still have a missfire and the p0303 came back. Do you have any pointers? Thanks bro
Hector do you do mobile work at San Pedro? I. Have a 2012 dodge grand caravan with misfire p0019,
I was born in Pomona!
Che Kelley 🙌🏼
TOOL BOX TOUR!?
Looks like cyl 4 plug was left loose or started to back out for another reason and killed the tube seal and coil
A la d*,> compayito ha ha ha good video i had the same problem with my wife 2010 Malibu a family member on her side washed the motor and misfired happen it had water in the plugs holes it cost me new plugs and coils I told her ya ves 🤦♂️🤬🤬🤬🤬
I have a Honda CR-V 2000 it was ok , after cleaning the throttle body now turns but no start. I wonder If you can help me with this car maybe you can send me a link. Thank you.
You might need an idle learn reset procedure
Compa, tengo una 2003 con el mismo codigo p0300 pero las bujias y bobinas se ven bien, una idea que pueda ser
Tal ves necesitas un Ajuste de Valvulas…
I subbed
I would guess somebody left that plug loose and that is what attacked everything. I have defiantly seen this happen before when a plug is not tight as it should be.
Air filter needs to be changed pretty soon
cainpaul08 yeah like yesterday.
Should've used the special tool to properly put the seals in correctly to make sure it sealed all the way around evenly.
I got 2004 Honda CRV , Error Code is: P0301 , I need to know which Cylinder ? and your recommendations Thank you
Nice video but don't use wd-40 on rubber parts, use grease instead or dish soap.
I have always used good old wd 40...what's bad about it?
@@angeldelacruz7254 Most chemicals, especially penetrating oils damage rubber.
In applications where rubber is exposed to certain fluids (brake fluid, trans oil, etc.) a special rubber is used to avoid damage. Haven't you ever seen a hose or rubber part (bushing) get destroyed from engine oil for example, that had been leaking on it? 😉
Hey bro..are you working any where near? Let me know I'm in Ontario, my 05 Accord has similar problem, and the dealer is a rip off
Angel De la Cruz I’m in Pomona. DM me on Instagram: Homie.Hektor
new subscriber here good videos im tryna watch all and catch up
Does the random misfire come back?
All chingaderas were installed 👍
Hello I like your video, pls my Honda CRC 2008 had miss fire cylinder 4,2 an random
Bro what kind of silicon did you use?
ghost regular gasket maker
Hey do you have to own you're own tools to work there?
WiredClutch Always own your own tools 🧰 🛠
So, any codes thrown AFTERWARDS?
Weeeoooo weeeooo I think maybe the vaaroom is broken
So el wd40 no le afecta con el oil or the plastic del los grooms
How much for the plugs and coil?
