How can you not appreciate this guy's honesty? Accepting humility like a champ! That is good $hit bro.

It's refreshing to see someone be truthful on YT glad you got to the bottom of what was making the noise nothing to serious or expensive, I tried Lucas a few years ago for a troublesome oil consumption issue didn't help that much if at all, last winter it developed a hard knock on cold starting I ended up using seafoam and MMO oil along with 15w40 fleet oil that worked good, now I use MMO and fleet oil the knock is gone and the oil consumption has gotten a little better great video thanks for sharing your efforts

No problem; You've just protected your engine even though it was a pulley....All is well!

Wow.... not only were you man enough to admit a mistake but you explained the real issue! It would have been easy to edit and claim your additives worked instead but you didn't. Bravo! And I wouldn't look at it like you wasted $40... you used good additives that are no doubt helping your engine out!

Wow ! Thanks for sharing, you just helped a bunch of people save money , and you proved that is always best to locate the problem before just throwing parts or additives into a vehicle....

Thanks for the video . Just fix mine yesterday . Timing belt kit set was the solution.

That is exactly how my engine is knocking and it happened just all of a sudden and I couldn't figure out why so Thank you very much for making this video !!!

Ceratech is an excellent additive that "glasses" over high pressure points in your bearings and valves train. It lasts over 30k miles even between oil changes. Agreed, check pulleys, idler and tensioner gear at first signs of a knock. My only critical point: shake Ceratech like you are trying to break it before pouring it in. It tends to settle in storage with the beneficial, nano-ceramic material laying in the bottom of the bottle. I shake it up for at least three minutes before adding it to a fresh oil change, then add engine oil to the can and shake it up some more...just to get all of the good stuff stirred up and in the crankcase. It will not settle out in your crankcase thereafter if you daily drive it, or at least turn your engine over once a month. ^.^

Nice info good job. I'll remember to take "the" belt off when diagnosing engine noise.

I like your video. I don’t know why people talk bad about it. I think adding the oil additives helped also. I am just glad you got lucky with this car you bought. Good luck fir many miles down the road.

Cheers..was thinking a min or so into video that u did not mention how u arrived at train of thought to use additives..ie diagnosis of problem..good to see u got there in the end..a good learning curve for u..thanks

You can also put a 5/8 fuel line 2 ft long hose to your ear and start with all your drive belts and pullys tensioners etc or put it on your block or a valve cover its amazing whay you will find be carefull with the fan while engine is running Repair what you find and drive it noise is gone ! I also recommend shell t6 synthetic 5w40 and a good filter

WOW! I did NOT expect that! Thank you! I'm going to check this.

i always wondered how someone could possibly believe that they could "fix" a rod knock with ANYTHING other than a rebuild? 👍👍👍 good video ..subbed

That engine sounded like Prince Albert in the can trying to get out.....lol

sounds like a airplane flying by 😂

amazing product from liquimoly CERATEC👍

“GET TO DA CHOOOOPAH!” (Soon as I heard it)

if the bearing is gone then no amount of additives can fix that noise.

it was so clear that there was something wrong knocking, and but the way you can't fix an engine with an additive! for sure it help your engine to run smooth again

Great vid! I’ll check all pulleys first.

I thought it was the pulley band in the 1st place and I'm not near a mechanic. Your car now sounds brand new.

Adds additives to oil, notes how the noise gets less noisy. Says the fix was pulley, which oil doesn't affect. 200 IQ!

chapeau for the honest conclusion!

That was a good one I noticed the rpm drop bigtime after pouring in that Lucas gear lube way too thick.

Excellent video. Thank you.

A story with a twist at the end - Charming

LOL... great video! You're the most honest guy on KZfaq!

We have all done this , you are in good company

What was the pulley with the problem? Is that a v4? Thanks

Whats the stuff in the black and silver bottom...

I hope you drained some of the oil before adding the oil additives ?

did u drain any oil out to make room for the Lucas?

And the liquid Molly did you drain the Lucas out first

Good one, a surprise, sounded serious, new engine noise. Pulley#

I'm sorry, did he just add Lucas and Ceratec together? I'm interested in the engine if it really freeze up or how long did it go before you notice any problem? I've seen the german in a video said not to mix ceratec with other (In this case was the MOS2) as it may cause problem. Did anything happen? just curious

One question left unanswered ... Why did the engine sound quieter after the Ceratec was added? Much quieter than the Lucas additive. When in fact the noise was caused by and external a pully which had nothing to do with internal engine components.

Which Creamic Liqui molly is exactly please? 3721?

did the oil change the color after ceratec???

wow reading the comments alot of people didn't watch till the end

Also its funny how most people are so quick to judge and post their opinion saying what you're doing wrong and what it should be ..turns out almost everyone was wrong ..I can hear a big difference in before and after so apparently it was a good choice you made..then after fearing the worse possible outcome it turns out to be a very simple fix ..I call it a win win any day

Thaks for your honesty

I knew right away the diffrence between the lifter noise and something else thats kind of dump. My friend.

what pulley was it?

My engine is 1AZ it has a knocking sound on the left hand side. At times when you shift to drive the knock ceases, and at times it will not cease.But always when l drive for 500metres or more the knock will stop until when l start the engine again.

How did you not hear it when you were buying it?

144-46 "Ok Lucas is in the house..." 💨🔥🚬 😎 🤣🐐

pull the belt anytime you hear a noise. That will eliminate everything except the engine and transmission. Same thing with a locked up engine. I seen alternators lock up and the belt was holding tight enough that the engine would not turn over. Know a couple guys that replaced engines and then found the alternator was simply locked up.

So good man..

Thanks for being honest.

Pulley? sounded like a worn rod bearing.

had me fooled haha that's awesome good for you

woah! thats bad. I think you need more than an oil additive. I was concerned when I heard mine and its just a clicking. It was at the end of oil service and was getting low. Oil change fixed it. How much did you add? I would think you can add too much. What was the oil level when you started and could that have been part of the problem?

Do you really think it is good to mix two oil treatments together?? we don`t.. bad idea

the ceratec did good job the noise of the engine became much quite

Yeah watch till end good info,still its not a waste to put addt oil bcoz its can protect engine...

This additive it is indeed GREAT it does what says without a maybe!

DAMN!!! THIS THING WORKS!

BA HAHAHAAHA OH MAAAN THIS GUY...! One of the funniest video's i've stumble upon...!

Bars copper+ coolant sealer will fill up those bearing clearances nicely, until you hammer down real hard on it again.

Lucas is in the house!

Lol well if the engine is high mileage I'm sure the additive didn't hurt anything

Is it a 2 stroke

Lmfao I didnt think the 2nd coming of Christ could help that vehicle... then the end of the video😁👍

Wouldn’t it be an over fill issue now?

You got lucky bro😊

There are two things going on. Valve knock and I think you got small hole in exhaust

funny video bro! Too bad everyone didnt watch it til the end.

Thanks 👍

Hi Ed, next time when the sound return, could you test it with Nano GLAY (from korea) in your next video? Its graphene based and will work miracles. Its not a branded product but it works well for old and high mileage engines.

I did the same with a car just bought it has a lifter knock i use two lucas and two synthetic oil ahnd the noise its gone next time when the oil change came just use synthetic that will fix the lifter temporay it can last as far as you keep that car using synthetic ..mine still runing good after 2 years..

"Lucas is in the House" engine- wirrrrrrrrrrrrrrrrrrr

Good video non the less.

So what happened next ??

You try to use meguin super performance according to your vehicle recommended viscosity

Sounds like bearing in the motor like a conecting rod bearing or somthing

Both additives may be a bit much. Liqui Moly writes "It is not possible to use our MoS2 10W-40 in combination with Cera Tec, because the amount of solid lubricants in the oil would be too high." Though luckily the Lucas seems pretty ineffective.

This just happened to me sounded so bad thought it was piston slap took off the drive belts and it went away

Lol mine was the top engine mount slapping around. Thought I blew the engine

Brian, how is the Sonata now? Can you post a follow-up video for this?

It sounds like Arnold Schwarzenegger could be found in the background screaming "Get to the chopper!".

well I'll rather spend $40 and it's a pulley any day lol. now the oil additives won't hurt lol. but yeah sometimes the cheaper fixes are what the car needs lol. how much was that pulley? $25?

COOL THANKS

Did all that crap overfill your crankcase? That could be a bad thing.

You can fix it by yourself all you have to do is buy the bearings the upper and lower bearings and lift your car in the front and take your oil pan off and hand feel which bearing is loose and change it out and make sure you lube it up before you tighten the bearing and put it all together add oil and it's done no more knock.

Ceratec should be added alone and then run. You also need to vigorously shake the can. You need a few hundred miles for it to work.

what pulley was it please tell me im having same problem

Sounded like tensioner

As soon as you started it it sounded like a pulley lol man that sucks lol

Timing belt tensioner?

Good Ending I was going give a bad comment until I watched to the end. Good lad.

🤣 well at least your engine was lubed up good

Better and less expensive use higher viscosity oil. In older cars, try 15w50

you got to do oil change with a whole bottle of lucas

sounds like a helicopter flying over

Maaaate..... the only way you’ll fix that noise is turning the key off 😂😂👌🏾

Let me share my mechanic wisdom. No chemical or additive will ever fix severely worn or damaged engine component. Thickening the oil just dampen the sound but it will still wear down until it eventually falls apart.

You can't replace a pully?

also a bad tensioner can be heard chirpping or a idler pulley
