CHEVY COBALT DEAD MISFIRE / BURNED VALVE / CYLINDER HEAD REPAIR / PART 2

- Hey guys! So, I decided to finally share a video that I filmed and edited over a year ago. I had been sitting on this video debating whether or not I should post it because I did not like the video quality of the introduction. Anyways, I decided that I should finally post it because I think there is a lot of good information here and this video might actually help someone out. This video is Part 2 of 2, of the Chevy Cobalt Misfire Series. In the last video we determined that we had a misfire on cylinder number 2 because of a leaking burned exhaust valve. In today's video we take the engine apart to see if we can find the problem and repair it.
Incase you missed Part 1 here it is! • CHEVY COBALT DEAD MISF...

Impeccable work as usual!!❤❤❤
Enjoyed the video Eric. More, more, more 😀
My mentor showed me to fill ports with solvent and let sit to see if valves leaked. Then roll head over to other ports and fill.
It is nice to see that you are getting your hands dirty again...
great job
Thanks Eric, great video showing your process.
Brother your video is useful a lot of info like it bro keep it up 💪
Great Video
The best master
I finnaly found a shop owner that gives a you know what. It's a lil weird to be honest with you when you are used to the typical owners that don't care about anything except numbers. My boss goes as far as every Wednesday when snapon shows up he sends me on the truck and let's me pick anything the shop needs to make our lives easier. There are very few out there like this I am most definitely not leaving this shop oh and not to mention I am making more money then ever in my automotive career.
Very good job, very good job!
I used the suction cup on the valves many times, my Dad never used the drill. He said he could tell when it was lapped properly, but it's obvious you did it correctly as shown in the seat.
Did you use a calibrated straight edge on both the head and block?
What did you use to clean the head and block surfaces when using the drill?
Thank you for this video.
Except for you and Ivan, all I see today is engine swaps if the problem engine needs repairing. Work like what you've done is a dieing skill.
Yes I did verify the flatness of the head and block using a straight edge and a feeler gauge. Unfortunately, I didn't film it. On the drill I use a simple wire brush. It works great and doesn't tear up the metal. Thanks for watching!
@@ADVANCEDLEVELAUTOcan you please explain....
Why why why???
Today's modern cars eg Toyota Glanza, Toyota Taisor, has 12V and then drops to 7V in the door close signal voltage.
Whereas, it used to be directly 12V when door closed and 0V when opened in old cars.
But today's cars has 12V at door closed, and after 20 seconds, it drops to constant 7V. When opening, it drops to 0V.
Why there's delay in dropping to 7V at door closed??
What's the significance of this 12V to 7V???
Please explain 😊
Is this a long lost video from years gone by? I wondered because I didn't see part one or so I thought. It was from a year ago. I'm not complaining, whatever you release is worth tuning into. Whatever the reason it was well worth the wait.
I left the link to part 1 in the description. Thanks for watching!
The condition the burned valve was, I would have milled the valve seat. Even if the valve does not leak, this does not mean that it is sitting flat across its entire width and dissipating the heat well. You don't have to disassemble the chain tensioner. You can also preload it in its entirety. Testing for valve leaks better use benzine.
Very informative video. Great job !
No video in the description box…. Thank Eric for a great video.
It's likely running lean due to that cracked exhaust manifold. Probably gonna burn another valve unless ya address that.
Somebody was using low octane fuel. I've used a drill to lap valves since the 60s. Some say you have to go back and forth but when the valves and seats are ground it's done turning in one direction, not in a reciprocating motion.
This is why i use an upper cyl. Lubricant ! MMO works great ! Just add 4 ozs for every 10 gals of fuel ! Cant go wrong !
when you dropped the core into the adjuster i half expected it to spring back out triggering the self adjuster with the drop
Thanks for the video.
Thank you for the video great job❤❤
You should check the head and block for warpage with a ruler
It is unnecessary most times if the engine didn't overheat.
@@moshet842 over the years of mini heat cycles, may warp and if the radiator fluid is not changed as the service manual suggests
I did. I just didn't film it. Sorry
Its about time
Time to buy a lottery ticket. All three exhaust bolts without breaking a stud.
Burnt valve. The manufactures run the fuel mapping way to lean to improve their C.A.F.E. rating as really aren't concern with low term reliability. Ford 2.0-2.5L suffer from the same run lean condition.
They’re also using powdered metal valves and seats from FuManChu too.
They all run the same formula
Great great job man😊
Thnk u, clear and elaborate
13:18 - Eric's a sly one. He took that man's skills and daughter. 😆😆😆👍
I sure did 😆
@26:58 you forgot to mention to put a zip-tie to the chain-gear to hold the chain. still we love your work!!! 💪💪💪💪
It's a great trick to keep the chains from moving. Thanks for watching!
@@ADVANCEDLEVELAUTO : Keep up the videos, love watching you!
Nice job
Your level of knowledge is past mine so can you plz tell me how the compressed air works in conjunction with the water. Are we not forcing the valves away from the seat when we are forcing air in that direction?
Hi Eric! Hope u are doing well! Can u show us something about jdm speed limiter removal in japanese cars imported from japan cause in my country alot of toyota cars with 180kmh capped speed!
It would've been nice if u told us about the mileage, Just to correlate with engine condition.
That was a lot of work, I hope it was worth it.
Comprehensively I would change all valves at least all exhaust ones
Hello Mr. Eric, May we know where you learned programming modules, eprom, and key programming?
Multiple sources. I did a lot of my own research and took a few classes.
@@ADVANCEDLEVELAUTO thank you for the response Mr. Eric
@@alexismarcyting5340 Locksmith groups on Facebook are a really great source of information!
Hey boss i was watching a video of yours from about 2 years ago im looking at purchasing this g37 auto but its a crank no start
8:00 by inside out you mean outside in.
i'd never use a metal brush on that, use the rubbery ones please.
Are you talking about the valve seat or the timing cover, or both?
@@MrRightNow both
Nice video - how do you release the cam chain tensioner?
I got some lexus gs300 content if you need, I'm in San Antonio.
hi Eric wat can the fluid You put at part washer
Awesome ❤
Grasias
Isn’t the valve supposed to rotate over time while it opens and closes? It looks like those weren’t.
Remove heads from outside in. Not inside out.
Great stuff! What city are you in? I ned to hire you!
Hi Eric.
Do you know anything about Topdon Technology DS401 diagnostic tool?
I saw it at my local car mechanic, but wasn't really able to find anything useful on the internet about it.
Is it some sort of a clone or what?
Thanks.
Would've been good to test the springs to make sure they're not sagging.
Part 2?
Where is part 1?
Can't you crank a car without starting it by using the clear flood mode?
Some cars yes. Not always though. Thanks for watching!
Where are you located, could really use your help¿
Song?
I used 2 different songs. The first is "Ocean View by Patrick Patrikios" and the second is "Not from Here by Dye O".
I need to hire you. Where are you located?
Not even worth changn a tire on, rejct the request 2 fix, garbage car
SORRY BUT AT 23:15 YOU HAVE BUBBLES IN VALVE 1 OF THE EXAUST 1ST CILINDER!!!!!!!!!!!!!!! 🤪🤪🤪🤪🤪🤪🤪🤪🤪🤪
