Thank you
Hi
This little Corsa came to me due to being low on power, and due to smoking quite bad at times...
A quick scan and look through live data, didn't really reveal much, but a few testes, and yes... problem found!
I have not repaired this one, as major work was needed, and the owner was on a rush, but, diagnosed it was!
Hope you enjoy the video.
Any questions or comments put them below.
Like always, thank you for watching! - ยานยนต์และพาหนะ
Superb. I always learn from your channel i am 10 years old and love cars.
☺️
That's great!
Hope you do something great with your passion about cars!
👍👍👍
Top job Luis, quick and dirty, revealing it's clapped out as buggers. It is actually shocking that this thing was offered for sale as a regular used car and not a donor (or at least that's what the potential buyer being that keen on having it suggests to me).
☺️
Indeed...
👍👍👍
Thanks luis another very good diagnosis
Thanks!
👍👍👍
Hey luis , to me when you started de engine , it looked to me that i heard engine noise , because those engines , are great and quiet , well to me swap the engine that one is gone , nicely done , and keep up the good work , all the best regards...
👍👍👍
Thanks Luis keep up with the great work 👌
☺️
Thanks!
👍👍👍
Mmm guessing a auction car or someone sold on a duff car !!! Good diagnosis as always on your side
☺️
Good guess...
👍👍👍
My sisters mini was consuming oil in 240 miles it was going from max to min. in the end my last resort was to do an engine clean and use some stop smoke additive and to my amazement its not consuming oil anymore and its been over 2 weeks now with over 500 miles on the little thing. I'm not saying its fixed it for the long run but for the time being its running 10 times better than it ever was. I never in a million years would think an engine additive would help the car I thought it was all snake oil. only time will tell now, but that Vauxhall sounded rough when you first started sounded like knock, or it was drinking oil causing the engine to knock and ping and go ham in on the walls. that's nuts looks like someone put BB in the intake lol
☺️
I am not a fan of additives, but agree that in some cases it can help...
👍👍👍
@@LMAutoRepairs Neither am I, I got a car from a Dealership years ago that had used Radweld to avoid £85 for a new radiator. The heater matrix blocked up and turned solid, so they ended up replacing that too!
I've seen marks like that on cylinders when those awful aftermarket things incorrectly sold as an "air filter" have been fitted. The types with a tiny surface area that have mesh and oil soaked cotton material or the foam types with oil are completely useless. They are 12 times smaller in surface area compared to a correct paper type and do not stop dirt and dust getting inside the engine to damage it. You also end up with oil on the MAF sensor, no matter how people lie and say you don't.
Something has been scoring the cylinders.
I can actually believe someone will sell that with no faults, hopefully the MOT centre will not fake the result and fail it.
☺️
👍👍👍
perfect explanation, thank you so much
☺️
👍👍👍
Hi thanks for another great video, not a fan of the ecotec or ecorec as known as here.
New engine required which is most common route with these unfortunatley
😅
Ecorec....
Thank you for watching and for your comment!
👍👍👍
Well done 👏
Thanks!
👍👍👍
Sounds like the engine has "Piston Slap" will need a rebore at least
👍👍👍
The sluggishness is probably the cat blocked / melted from running poorly til it was traded in!
Probably...
👍👍👍
I have a much less aggressive ticking noise only on cold start n goes after 1-2 minutes or so after getting a little warm same z14xep engine any ideas?
mirror attachment on borescope might have picked up the cylinder head and valves area .as its alloy would have seen if marked badly as if its had maybe spark plug broken ceramics rolling around
Could have done that... ☺️
Seen enough on the cylinder walls though...🤪
👍👍👍
Looks like pre ignition damage to cylinder wall. Would have liked to see top of piston, probably missing part of the ring land
From high temp ratling
☺️
Thanks!
👍👍👍
Engine sounded off somehow... I'm listening to my Corsa
Agree...
Though sometimes the sound sound a bit different on video, but yes, it didn't sound too healthy...
👍👍👍
good morning luis
👋👍👍👍
Those indentations are not , what you see are oil drops , and some vertical scratches , maybe at some time the engine was overheated , the piston skirt scratched the wall , the oil scraper is damaged or locked and there you have it ....
Possibly...
It definitely doesn't look like oil drops...
Too consistent across all cylinders... and no reflection... which would do if was oil... ah, and no running oil down the walls...
Not convinced they were oil drops... but who knows...
👍👍👍
I've seen this sort of pitting on cylinder walls before, in my case the petrol fuel was contaminated with diesel fuel. The diesel caused the pitting.
Interesting...
👍👍👍
Rust been cleared and present like this
☺️
The compression on this engine should be 14-16 bar, check the manual 😉
Probably... anything above 180psi and these engines run pretty smoothly...
The 160 on this was however low regardless...
Thank you for watching and for your comment!
👍👍👍
@@LMAutoRepairs 180 psi is also low, the engine may run smoothly but the pistion rings are a bit worn in this case. 16 Bar or 230 psi in each cylinder is the value which these engines have just from the factory :) What about this engine? Did you rebuild it? Usually crankshaft bearings sound like on the video on these engines. Cylinder wall damage is terrible... Poor Corsa 😔
@corsik737
Indeed poor corsa...
No I didn't do anything to it...
My guesses are that either another used engine has been put in there, or it has been scrapped...
@LMAutoRepairs that's really sad... The engine is still fixable, and it's not that hard to rebuild this one actually
But yeah, the owner might be greedy and probably don't want to cure their injured babe 😔
@corsik737
😅
👍👍👍
Which you decide swap engine from graweyard or renew allready broken one or buying a new motor
Economically, probably a know good engine replacement is the most sensible option...
In my opinion...
👍👍👍
Sabes me dizer qual a abertura do elétrodo das velas do corsa D 2007 1.2 80cv se e 0.9 1.1 ou mais e parabéns pelo espetáculo de mecânica e suspense.
Olá!
0.8mm
Mas 0.9mm também dá...🤪
👍👍👍
OBRIGADO@@LMAutoRepairs
Maybe incorrect piston ring installation... It would explain the loss of oil etc.
Could have been...
👍👍👍
Bit of a taping issue there too . Can I ask how to you identify what engine is in a car
Hi
Either the scan tool detects it, from the ecu information, or I look for the code stamped on the engine block...
👍👍👍
Looks like the top of a spark plug size?, maybe dropped in.
Possibly...
👍👍👍
👍👍👍
Thanks!

Thanks!
👍👍👍
Hi, Where are you based, mate?
I am not a mechanic, but I think the borescope images look like oil droplets on the cylinder walls. That engine is too rattly and needs a major attention! The guy selling the car must be Arthur Daley. Well this car is going to bite him, unless he got it very cheaply. At least you done your bit.
☺️
Indeed...
👍👍👍
That would be a scrapyard for me, maybe that's why there stopping putting dipsticks in engines because you have dipsticks driving them and not checking the oil.
☺️
The mechanic doing the head gasket should have stopped the job when he saw such cylinder bores. The question is did he saw them. They did not diagnose the problem the first time. Burning Engine oil because of headgasket is very rare problem.
Agree... with the head out it takes no time to look and inspect the bores...
👍👍👍
Send it back to the 'block'
😅
Done!
👍👍👍
Sounds like a diesel 😂
😅
👍👍👍
Typical Corsa engine
They initially took it to the wrong Mechanic, they did not know what they were doing...! Even in Africa, they could have made a better diagnosis and repair...! They should have checked For Sideways Movement on the Pistons when they had the Cylinder Head, Off..! This would have indicated to them, the piston rings were Worn (Lack Of compression)..! Replacing the Piston Rings, might solve the Problem or in extreme cases new cylinder liners/ cylinder Block might be needed...! It might just be best to change the Engine on this Car, for a Known /Tested Correctly working Engine...! 🤔🤔😇😇
☺️
👍👍
Your ment to have the throttle fully open when testing compression.
Sorry, but why?
Yeah but usually it won’t make a big difference
You will need air to come in,because it acts as an airpump!@@hermannmuller8961
Considering the general state of the engine, I think it's unwise to start Rev the engine really high.throttle fully open when testing compression ??? Who told you that lol
A pressure transducer is nice for this diagnosis ( DITEX or pico )
These engines are bad once head warped,usually just replace engine with a good one
☺️
👍👍👍
only 81k , that poor engine is done for, had a bad life
😅
Looks like...
