![Top 5 Symptoms of a BAD TIMING CHAIN [What to Look Out For]](http://i.ytimg.com/vi/7beQX8cE-18/mqdefault.jpg)
$200 Jeep plus $200 Alternator = years of good service for your Dad. That is awesome. Thanks for the education.
I love these kind of humbling stories.
Thank you ❤️
Yeah humbling to the crappy mechanic that condemns a good engine. 👍 Good vid
Kenny I absolutely love your videos,a real guy doing real car stuff! Thank you for sharing of your wisdom and experience!
My son's 2019 GMC Yukon was making a "motor noise". I could hear it and reached into the front of the motor, while was running and laid my finger on the tensioner bar that keeps the serpentine belt tight, and could feel the plastic tensioner wheel bouncing on each revolution. My son was in a hurry and I told him he either needed a new wheel with better bearings, or to have the existing bearing lubricated. Since it is his daily driver, he took it to the dealer, who suggested valves and lifters, and possibly new cams, and told him it would take 3 weeks to even look at it. He then took it to the local experts in his town, who can literally fix anything from a Maybach to a VW, told them what I had said, and what the dealer suggested, and they spent a minute filling the bearing with grease. End of Problem.
Kenny, you don't just repair mechanical failures, you pass on a great amount of hard earned wisdom to your audience and I enjoy your videos and your southern personality. You are part of the core pillar of America, the honest, intelligent blue collar folks who ARE America.
I have a 2000 Ford E150 with the 2 valve 5.4L. it works great IF I change oil regularly, use 5W-20, (NOT 5W-30 as the manuals says) & keep it topped up. If it gets low on oil, if the filter gets clogged up, if the oil is to heavy, then I get valve noise, rough idle, sluggish performance,etc. Ford put out a service bulletin on the 5 4L engines saying to use 5W-20 oil. The 5.4Lhave a few issues but they work great if you pamper them a bit. The critical thing seems to be oil, if it has oil issues the plastic timing chain tensioners break & you'll be doing major work. Oil is cheap compared to a motor job.
....great tip Kenny on loosening up that belt and then listening to the engine running....awesome....thanks for posting... 🙂
I had a friend put 2 starters and a battery on a pontiac 3.1 v6 back in the nineties. It still would not turn over. He finally noticed the crank bumping over a tiny bit when trying to start. Yes, the alternator was seized and holding the engine by the belt. The first thing in mind isn't always the right thing.
Great video. Thank you. You are proof that there are still some real mechanics left instead of the majority of "techs" that can read a code reader or laptop and throw parts at cars.
My first thought was a bad bearing in the engine. Thank you for teaching me something new!
When I was in 1st year mechanic school our instructor got us all to list as many things as possible that could sound like an engine knock, it was a long list.
Absolutely! That is another reason why it is important to talk to the customer about their concerns regarding their vehicle. Thanks for watching!
Kenny,
I can't decide whether to describe you as amazing, or brilliant. Perhaps both!
Take Care,
Tom K.
At first glance that vehicle looks nice and clean. That should make you enjoy fixing it that much better.
In 2010 I needed a car bad. Went to look at a "dealer special" adv. car. They said nothing was wrong with it but I got the thing for half the adv price. Found out that the car would blow the gas pump relay and the fuse box (under back seat) was melted where the relay plugged in. I removed the fuse and relay, I rewired an external relay and fuse. Cost me like 20.00 bucks total. This is my 2008 lucerne with Buick's best engine - the 3800. I still drive it today - its been 13 years. Always starts always runs. I am very religious though on maintenance though. I have 160k on it now.
The "process of elimination" works wonders for mechanics? Thanks for showing that method in reality, Kenny.
Great video and story, Kenny. By far, the most realistic honest mechanic on RUclips.
Wouldn’t have believed that thanks for a very good video Kenny.
One thing I learned as a younger technician was the three c . The concern the cause and the correction. 1 you have to confirm what the customers complaint is.the concern2) what is the cause of the problem ( back it up with a test ) what is the correction. That was from a U Haul training class. I fixed a lot of cars properly with that information. Never guess always test ….
Dude! Thank you. If i hadn't have seen this, i wouldnt have believed it.
My shopping used cars knowledge has just become stronger.
That's a good story. I have never removed the belt like that. I will now.
That’s crazy!!
I thought for sure there was some timing issue going on with that motor.
Thank you for teaching me something today.
Years ago, I went with a friend to look at a late 90's Lecacy wagon. It had the EJ22 engine with a loud rattle noise. A shop had told the owner it needed an engine. My friend bought it for $700. The water pump was bad. We replaced that along with the thermostat, timing belt and cam seals. He drove that car for years.
Seeing as I drive a 09 F150 with the same engine, that's GREAT to know! Thank you!!!!
Test don't guess is always best, especially when the test is practically free!
Great story, good lesson, thanks.
The jeep story was interesting and also came with some knowledge. Now im going to that every time i hear a knock.
Thanks Kenny! Enjoy your videos.
Usually learn a little something I can use.
With the history of those engines especially when not serviced regularily and finding low oil you would assume the usual stretched timing chain and worn out phasers and guides . Good advice always check the easy stuff first.
Kenny you are the man! see this is what a master technician does u r not a maniac u actually do the right thing your donistic skills are amazing! like u say keep wrenching!
Thank you! I appreciate you watching!!!
Thanks for the video Kenny nicely done 👍. Take care of yourself and family and be Blessed ❤️❤️❤️ it.
Dad always preached the exact same thing to me. You never know, check all options.
Nothing better than experience. Today if scanner doesn’t tell you what to do it’s not fixed
Smart man. Eliminate the easy problem areas first. Not all noises mean a new engine.
Great work Kenny
i have had a water pump sound just like that rumble its worth pulling the belt for any noise KW
My daughter's 3.7 mustang had a funny noise it ended up being the water pump pulley had play. Just a little bit. But anything other than none is bad news and it made a racket especially when cold. Easy fix.
That is a good combo of story time and diagnosis with pulling the serpentine belt to isolate the noise.
Whenever I change the worn out serpentine belt, I'll spin the pulleys by hand to listen and feel for rough bearings, but I never ran an engine with it disconnected
It won't hurt for a short time w no water circulation
Yeah it's not gonna hurt anything,you've got a few minutes actually.
I've ran engines on the floor with no coolant for long enough to make sure they didn't have a rod knock.
Worst thing is if you drive it ,no power steering ,no alternator etc but you'd be ok pulling it in the shop like that.
My first thought was a rod bearing knocking. Great diagnostics.
So what was the problem exactly?
@@bam9138 looked like the a/c clutch was fubar
Excellent diagnosis.. Im sure the owner would be pleased with that news...!!
That's how I bought my current F150. Just clicked when you tried to start it. Previous owner replaced the battery and starter to no avail and decided to sell it. After checking out several things I discovered that the AC compressor was locked up tight. I installed a dummy pulley in its place and the truck runs great.
I just had a 2013 Cadillac SRX that had a locked up PS pump. The guy was driving in a parking lot and the car just stalled, no noises or symptoms but would not turn over. He had it towed home and put a new battery in it and proceeded to try cranking it until the starter smoked and burnt the 300 amp mega fuse.
So, I just bought a 1999 Ford f150 5.4 . I can drive it for two weeks everyday to work and back and errands and it be fine. Then one day I can drive it and it will use about half a gallon of water. There is no visible leak oil looks good. The day it looses water it will continue to lose water that day. Then it will stop and I won't lose any for a few days again then it will just do it again for a day or two then go away again. I have had the white smoke happen when it does lose the coolant. But, never smokes after I drive it just when I start it up. Does have a slight shake to it while idling but the rpms does not move so not sure what's causing that. Had it hooked up allot showed was a misfire in cylinder one changed the plug and coil and nomore misfire. Has a new thermostat new idle control valve. So, not sure what's going on. Sometimes, now when I go to crank it it sounds like it wants to sputter for about a second or two as soon as it starts but it smooths right out.
I bought a 67 Chevy 2 in 1970 it had a one time ticking noise no body could figure out , then one day I pulled the dip stick while it was idling and the ticking stopped , the dip stick was hitting the crank cheek every revolution , end of story .
We have seen this hundreds of times you need to diagnose good job
My old mechanic used hold a piece of hockey stick to each component on the serpentine to find the noise
I sure would have bet a paycheck on a cam phaser. Surprised me good job ❤
I had the same thing happen to me on a 3.8 air compressor seized up.
Had a similar experience with my Caddy. Had a no start one day and at first thought it was the starter because testing told me battery was good. I had seen a seized alternator stop a pickup from starting at a GM Dealership I had worked at once so I loosened the belt off and found it was my AC compressor that was seized ... Like you say .. "you never know". Don't assume; just check all possibilities .. What if??
Nice clear demo.
Tips of the trade. Thanks!
Thank you for the video, Kenny!
Damn! I thkught for sure that was the bottom end. I thought the sound would still be there after the belt was removed. Awesome video
Excellent Tech ya are! :D great advice! great example! Love the videos! :)
I love your vids. I no sooner hit play & I immediately hit the like button because I already know.
My Mustang with 4.6 did that knocking noise too, it was a shield inside the valve cover that broke loose and was riding on the cam lobe.
I am impressed!
Good find Kenny
Nice tip...
Yes hear very clearly clutch clatter on ac compressor so could be just clutch not whole compressor
Common sense mechanics. Thanks for sharing. You had dropped off my notifications for a while. Glad you're back. I gave the 👍 hopefully this will keep em coming.
First thing I do when I suspect a rod knock is pull the dipstick while it’s running, hold it the sunlight and look for metal flake. I am the destroyer of rod bearings and the occasional rod, piston and oil pan. 😂
A Petroleum Engineer came to us after being laid off at Texaco. He had a 70s Plymouth Saturn, Surfer edition. My coworker and I both wanted it and he knew it. Came in one Monday and he had sold it to an other employee for 500 bucks as it need an engine and he wouldn't do that to us! Guy added gas to it and drove to for years with a bad gas gauge!
I’ve had a few mechanical fuel pumps go bad and cause a knocking noise, the good old days
Great video Kenny
I thought it was the engine too. But, I have also been fooled before more than once.
Just think how many cars get hauled off to the boneyard for bad diagnosis. Good catch kenny you the man
Had to haul off my nice 03 330I bmw in 2018. I now am fairly confident it was the spark plugs. Multiple reasons why so I am confident and sad that I had to lose her
Great video. I learned something new. I just bought a Dodge Ram gonna try this, you never know.
Thank for the video
Great catch kenny
Hi, Kenny I’m over in the UK it’s such an amazing information you’ve given me you would call me a old timer diy mechanic I’ve a 2001 MGF sports car , it’s the last British sports car made by MG ROVER your video’s are full of great content you should be proud of yourself and thank you for sharing your experiences.
Excellent tip
Thank s!
just a week ago I encountered the same noice! the mechanic that repairs my BMW E36 changed the belt with a larger one and damaged the tensioner . He was adamant that the noice was there when I took the car to him so its normal, I ended up changing the belt again and the faulty tensioner and the car is back to normal.
I wish I was in your area. I need to find a mechanic that wants to work. I have a 2011 Chevy Caprice PPV Making a high pitch screeching noise coming right from the bell housing in sync with idling. I took it to a shop and he insists it's coming from the oil pan which it is NOT. Loudest point is right from the inspection cap on the 6l80 Transmission. I can't work on it here at home since I rent. No working like that allowed. I did remove 1 coil at a time while idling and no change in the noise at all. Not rod caps coming loose like he said. It would knock not screech.
Great info Kenny
My father and me went to look at a 70 impala in about 1980. It was knocking. I told dad it's knocking?! The owner went inside and dad said look he sprayed wd-40 on the belts no more knock. I bought it for $500. Drove it till fall and put the 300 hp engine and transmission in my Camaro. I never thought the impala would be a good car too.
Car lot up the road from my shop brought me a Chevy Cruze and told me to put a motor in it. Pull motor and trans out bottom and find locked. Up alt and locked up ac compressor. I compression tested engine and set it aside. Next Cruze. That needs a 1.6 I got a good one.
I was told never ASSUME because it makes an ASS out of U and ME
Keep up the great work
Waiting for a follow-up for the cause of the noise...
just great video, really great stuff, always watching from the uk
It sounds like a cavitating pump. Possibly Power steering? But could all be part of the ac compressor.
I have a 2004 Pontiac that was making a noise I thought was inside the engine took the belt off engine was silent. Turned out to be a bad crank pulley.
I have seen on 4 occasions 3.5l Ford v6 engines "locked up" by the alternator. All, the engines were condemned.
Tale off the valve cover and visual inspection of valve train?
Wish you lived in san Antonio tx,so u could look at my navigator.its making the same noise
Just changed the alternator in my Jetta. I thought it was rod knock till I pulled the belt
Water pump here on my 2004 Pontiac Vibe GT
Only 142k in a Toyota engine I was like WTF and sick to my stomache for 3 days (thinkin my payed off car that i banked on lasting 250k miles was fucked lol) until it got into the shop lol
And my Serp belt needed replaced anyways so it killed 2 birds 1 stone, $400 later and belt tensioner and pump were changed and g2g
learn something new everyday
2 things
i suspected it was a pulley from the start
also, your story, why did you cut the belt ?
We had a customer bring tow a Chevy pick up in with a reman engine in the bed that he wanted us to install, the alternator was also locked up. We informed him but he had already purchased the engine and wanted it replaced anyway
From watching your videos' I knew it was the compressor causing both problems.
I am a dum dum… but I must ask: so what was the problem? The compressor or the belt? I am just starting to learn about engines on YT.
Pour some marvel mystery mix in that mug and valvetrain noise will quiet down
Just keep clean oil in those 5.4 engine's and they'll run along time without needing internal engine part's.
Sir whats the issue here. Got the same problem. Whats the fix
I thought for sure a bad main bearing in engine or cracked harmonic balancer hub.
What ended up being the issues
so was it the a/c compressor?
Remember when oil came in round cans and you needed a piercing spout to open them.
HOW DID THAT GO
Sounds like the lower-end is wore out
Kenny "Columbo" gets his man, again
Don't know ford, but what is the compressor for?
