Yes, leak down test would have took the guess work out of the equation and given the client a more accurate diagnosis. You don’t always need a machine shop to tell you that your valves are leaking.
Watching your videos, you seem like a great mechanic, slipped a bit on this one. If its an interference engine, dont continue cranking with jumped timing risking further damage. Compression test is unreliable with jumped timing. Leak down test would confirm any valve damage without removing cylinder head. Leakdown tests are a bit of a pain but reliable.
Wow. What you actually did in just diagnosing is just stunning. You disinsect half of the engine, did compression test and also explained them a to z what could be wrong. Speechless. Wish my mobile mech in the area would do half of what are you doing..
It's got two bent valves ,,, you could lap in a couple of valves on your tailgate ....compression is low on the undamaged cylinders because the cams are out of time with each other ....
No point doing a compression test with a loose/jumped chain. Further more, you risk doing further damage by cranking it. The best way to check for leaking valves or piston ring issues is using a cylinder leak down tester👍
Not all motors are the interference type. For those that are, how many times do you think the customer or neighbor has been cranking it before he got there? Furthermore, if the head is pulled, guaranteed the machinist is not going to replace just the bent valves. A compression test for suspected bent valves in situations like these are fine and not going to cause any unnecessary expenses.
@@kellyappel301590% of all new cars are interference FYI. Compression test could do more harm than good assuming they had been cranking engine w bad timing chain. A leak down test would determine the problem without any un do harm here
@@kellyappel3015 The problem here is the timing is off since the chain is loose or skipped. The valves are not closing in time, either too early or too late so the air leaks. The compression test will not give any good readings. No point in doing a compression test if we already know the timing is off.
@@turretop5675 Low or no compression will verify that the tiiming is off, or valves are bent. The main point of my post was that it certainly isn't going to cause more damage.
You will run into the same issue often with a cylinder leak down tester with jumped timing, I personally have. Cylinder leakage testing requires being set to TDC on that cylinder, if timing is off and one cam is holding open valves at TDC, won't work as obviously it will leak out those valves. The only accurate way I know of checking bent valve/rod condition with jumped timing is: 1. Checking for visible failure using borescope (this would show with a valve not sealing at TDC compression stroke on the cylinder being checked; or you could see the cam sprocket failing to rotate with the engine as well, another common Hyundai/Kia failure point.) 2. Rotating engine with something in the spark plug hole and inspecting for one that does not reach the same height at TDC, indicating a bent/shorter connecting rod. However, pretty frequently if you bend a rod it tends to prevent rotation at a certain point when it hits the block/oil pan casting. A personal observation of mine to be taken with a grain of salt: the Hyundai/Kia engines I've seen jump timing have seemed to bend valves like clockwork, and I've seen over 20 instances. But so far, I have yet to see a single case of it taking out the block on the 2010+ Hyundai/Kia engines. Not sure why.
Leak by test. Air up the cylinders. Remove the radiator cap and oil cap. It's how you find cylinder leaks. Out of time? Relieve the cam caps. Bent valve's won't close. Most likely it has an interface engine. Look it up.
Never stick sumthing in the cylinder and crank it over unless it’s by hand. That coulda got bent up inside an coused damage I’ve seen it happen . That was a bad call there .
Many possibilities. How many miles does that car have? I change timing chains on those vehicles every 150000 km / 93206 mi. For me sounds like tensioner did the stuff. (Corrected the km, was 150000, not 15000.)
Interference engines are the worst, when the timing belt/chain snaps it completely destroys the whole engine. I definitely prefer driving cars with non-interference engines, at least when the belt/chain dies the engine just shuts off with no damage.
He might have been doing a compression test to see how bad the timing might have jumped. It's not like he tried to keep going till he got good compression.
I’m still learning how to work on cars but my first thought was do you want to leave the cover off while doing all that? Do you worry about debris coming in? Thx
my kia soul 2016 1.6L has 250,000 Miles on it I was under the impression since its a timing chain I dont have to change it but then this guy was telling me I better change it, what say master mobile mechanic
I wouldn't let this guy swap a battery, he'd screw up the ECU, that test and how it was done means nothing, I've never heard so much BS from a "mechanic" in my life, he's self-employed mobile because no one will employ him and he has no money for a unit,
That's a bunch of crap. This guy does a helluva lot of free work for less fortunate people. At least he's got a heart unlike a lot of keyboard warriors like yourself.

wish they would tell u how much it cost on the car repairs, any ways i aint gonna watch no more! peace!
@@beexiong2171see ya , I’ll keep watching , I like his content
You should have rotated the cams to close the valves on each cylinder did a leak down test. The compression test won’t be accurate with the timing off
Exactly leak down test with valves closed tells you all you need to know

You could check the valve clearance if you don’t have a compressor if the clearance was s excessive then the valve is bent
As soon as I heard what he said, I thought the same thing.

It's got two bent valves ,,, you could lap in a couple of valves on your tailgate ....compression is low on the undamaged cylinders because the cams are out of time with each other ....
Old guy had no clue what was going on.
you could easily scope the cylinders before doing anything and see if theres damage
probably hasn't got a boroscope, he is useless, worse than useless, only these two old duffers know less than him,
You can buy a scope cheap these days too !
you can but you wount see it in full lenght, valve guides can also be also bent you can see dose also
First time I heard you say engine, that’s a Mastertech right there
It looks like timing chain tensioner failed and the timing skipped. You're right, better check the valves for damage.

That’s an expensive motor. Kia has a recall and you can get a new motor for free!!
they gave me a free engine last month! kia sedona 2016
@@crackerbrick1903how is it going with it
There’s no recall for an engine on that specific kia
Not only that the recall does not cover timing or low compression issues it’s specifically crank bearing failure
@@davidh1263 Because Kia/Hyundai have these specific problems i would always try if they would help you.
If it was snapped it wouldn't have audible compression bumps when cranking.

you must put engine to time before any compression test or free the chain after removing cam shafts to ensure all valves are closed
Use Lava Soap for poison ivy. Let it dry on the rash, then wash it off.
Yeah looks par for a KIA. My nephews lasted like 2 days before dealer had to replace engine lol
I don’t understand how they get away with making timings chain and tensioner so weak ,then plastic oil pumps intake manifolds are all trash now
Can you run a cylinder leak down test to check valves? Just curious

Hope there are no damaged pistons.
Telling them that you have to take it to a machine shop and take it out to test it is bs. They call it a leak down test.... Wth?
Go do your own videos and do it your own way and stop whining about how he does things.

Many of the longest lived engines ever made are interference engines.
You can't get an accurate compression reading if the engine is timed out.
No way to do a compression test with cams off
He does not know what he is doing. He wants good compression numbers when the valve timing is off? 🤦🏾♂️
He might have been doing a compression test to see how bad the timing might have jumped. It's not like he tried to keep going till he got good compression.
I’m still learning how to work on cars but my first thought was do you want to leave the cover off while doing all that? Do you worry about debris coming in? Thx
You cannot possibly check the compression properly on an out of timing engine ! Obviously it is not an interference engine huh !?
The biggest problem is. Its a kia...
BS...that engine all covered in varnish and some sludge tell the real story...
It jumped timing the chain is not broke the cam were still turning.
Do you have any videos where you actually fix something?
Their first mistake was buying a KIA.

You don’t change timing chains until they go bad. Thats a lifetime part that may not ever need replacement.
@@ButtmanAtHeart uhh ok, if you wait until they "go bad" yhou might as well kiss your engine good bye
