@@MayoCarsDR You’re so welcome! All the others talk talk talk when all they have to do is just watch your video and learn the smart way to do it quickly and easily & create the most effective tutorial video! Thanks for all the great content!

@@MayoCarsDR I have a very strange thing going on with my 2010 Lexus HS 250 hybrid, 110k miles. I bought it at 103 K miles, did oil change, did another at 108K miles and suddenly at 110k, the check engine light came on with the POO12 code. And engine noise. Not too loud but of course I’m concerned. You hear it when the engine kicks in but it seems to quiet down as you drive, but it’s hard to tell from the inside of the car. We changed out the camshaft position sensor but the noise continued. Then they changed out the oil control valve but the noise continued. Today they are changing the timing chain tensioner and hoping that does it. If not they think will have to go deeper into the engine. One mechanic said he could see tiny metal shavings in the oil & it was dirty before the last oil change. They took the valve cover off and the timing chain looks good and it was tight. They didn’t see any broken chipped or bent pieces on the sprockets. Your thoughts?

@@MayoCarsDR Well it was not just the timing chain tensioner. That sent me back about 400 and they told me they’re gonna have to dig down deeper in the engine and replace everything that has anything to do with the timing chain. That’s where the noise is. And now there’s three distinct noises and it’s worse than it was before. So I’ve spent $1000 so far replacing the camshaft position center, the oil control valve, and the timing chain tensioner. Now everything else is going to be $3000 minimum. The labor alone is $2000. And right now they really can’t tell me if they know what’s causing the problem. Your thoughts?

This way the VVTI and timing chain tensioner can be damaged ,but you send me a video

Same problem with my 2010 Corolla with 100k miles. Did you fix the problem?

Thanks for comment

Thanks for comment,It cost about 800 USA dollar to fix, but if your Corolla has a 1ZZ-FE engine, that's not a problem.

Change air mass sensor and fuel injectors

I don't know anyone there

If you want to change the VVTI, you can change it without taking the engine out, but if you want to change the timing chain etc., you have to take the engine out.

Which vehicle do you have and the sound can come from the front or the back

2003 altis corrola front when I'm breaking

If noise came from the back what does mean?

U need to grease the ends of your brake pads and grease bolts

yes,It is possible but a little difficult

@@MayoCarsDR possible in Lexus es350?

Remove valve cover and check chain sleeper dempr

10w30

Yes, I noticed that too. My 2009 Corolla uses 0w20 full synthetic.

Bad Chain Tensioner

Yes of course it could be a timing chain problem

If it is not changed, these sounds will gradually increase

@@MayoCarsDR Yes, I was told this. I don't care for now. We'll see if I care if it's 15 seconds of it.

Chain tensioner

Thanks for comment, It cost about 800 USA dollar to fix,

Labor 200$

I have a 2010 Lexus HS 250 hybrid and it’s making a noise too, but not this loud. The dealer wanted to charge me 6000 so I walked. I found another guy to diagnose it and I’m hoping it’s just the timing chain tensioner but I’m wondering what the heck happened to it? It’s only got 110 K.

@@weaverdreams it happens after 100k because the tensioner don't hold the oil, this is manufacture fault in this design of tensioner

2010 139981km

Horrible they need to recall and fix all their mistakes.

@@JB.1234LOL 😂😂😂😂 How abour Ford & Chevy.. per vehicle Toyota has the least issues. Work on a few and you’ll see

@nordicpride9708 i dont drive a ford or chevy so i dont know how they are but i do know Toyota and the quality has gone down 80% since the 90s.

After 200.000+ km mine has the same problem too. I'm actually happy, a friend of mine with a bmw had to already change his engines after just 60.000km.

​​@@JB.1234since the 90s? are you high? their 9th gen is one of the BEST generations they've EVER created and this is unanimous across all engineers, technicians and virtually any mechanic. that spans from 03-08. since the 90s? get with reality bro lmao their 98 corollas were trash with horrible oil burning and leak and gasket issues and master toyota mechanics will tell you this all day long.
