Quick & Easy way to Diagnose a Rod Knock vs a Lifter Tick on your engine

[@NorthwoodsAmerican]

Old mechanic friend taught me many years ago to use a cut off section of old garden hose to hold up to one ear and move around. A lot cheaper than a stethoscope and works great at isolating sounds

[@Payote88]

Also a screw driver works. Listen through the handle. The old wood ones work the best but they all work!

[@TheRealPOTUSDavidByrd]

Good video. For those curious Lisle makes a mechanic-specific stethoscope kit with two different listening rods to detect either mechanical or air/vacuum type noises. Part # is 52750 and costs a little over 20 bucks.

Hey auto guy diy love the old school methods for sure that’s literally the way I learned I just wanted to add if a guy didn’t have a stethoscope you can always take a long screwdriver and place the flathead (etc) end on the valve cover or oil pan and put your ear on the handle end it also works great to single out what pulley or tensioner has failed along with many other uses just make sure your hoodie strings necklaces etc are not going to get into moving parts such as fans belts etc thanks for your time and videos

Good thing I came to your channel i honestly thought my lifter in my 6.4 hemi was going bad but its the injectors functioning properly. I had my SRT for 11 years now and do my oil change faithfully every 3,000 miles with 161,000 on the dash from day one.

[@FoolintheRainSDMF]

The screwdriver example is straight forward and clear to tell the difference that was a good one to show people who dont know and we should tell these people who dont know that if anyone tries to sell em a car and says,"just needs a rod." Almost like it aint no thing, not to believe its as simple as all that. Rods,bearings,lifters,cranks,cams,head gasket without taking the head off the motor to resurface and check at a machine shop. All that shit is involved and expensive especially if you're not down to do it yourselves.

You can use a mechanic's stethoscope, eg a screwdriver. Place the handle against your ear and the blade against whatever part of the engine you are trying to diagnose.

That’s what I was going to say lol screwdrivers are such a multi purpose tool when ya get done clicking them together to determine the sound which is a GREAT description ya then stick that bad boy up to your ear while touching the top to spots on the motor and see if you hear the familiar tick of the screwdrivers

[@AlphaBobFloridaOverlord]

You're good! I genuinely learned something important today - now thinking that I've got a lifter tick.

[@JimofTheLionKings]

Great video. The screwdrivers perfectly represent those sounds, except I am still stumped. My mother has a 2016 Cadillac ATS 2.0 turbo. I have been cleaning up the car, doing some service work on it, and getting ready to sell. The car only has 67K miles on it, and suddenly, I have the loudest knock I have ever heard. Sitting inside with the windows up and the hood down and locked, it's so loud, like I had the windows down and the hood open. The tone is more like the sound of a rod, yet it sounds like it's coming from the topside. I haven't been underneath it yet, but it may not make much difference in determining where it's coming from because it's so loud. Damn, I need to get rid of this car like yesterday..Ugh!

Just take it easy on it and pay close attention to the knock check your oil atleast once a week. You should get plenty of miles out of it. Never give up hope big dog.

@VictorLSavage02 oil pressure is fine that abiu what my 09 ram runs. If your nit having any issues with the thicker oil stick with it. I always run a 5w30 in the summer and 5w20 which is recommended in the winter months. That seem to work pretty well for me sir

My noise also goes away and isnt there after car is warmed up...I barely hear it at all...now yeah that could be exhaust leak that sealed up when everything got nice and warm but it could also be that the lifters needed time to get lubricated...

I have a 2005 GMC 5.3 pickup truck. Here are the details of my issue: When I first start it in the morning, the oil pressure is fine but after the engine heats heated up and about 10 minutes of driving I hear a heavy rattle in the motor...this only happens upon any type of acceleration from a stop light or even accelerating on the highway, or street, even light acceleration. it is a content issue from that point forward, until the motor is stopped and given time for the time to cool down... Also after the engine heats up, the oil pressure drops somewhat..., also when I first start the cooled engine, I notice a heavy blue smoke from the tail pipe, this only lasts for a few seconds and then no more smoke... It has about 160,000 miles. Thanks for any advice you have to offer.

I have a 2003 Silverado 5.3 L. It set for two months and was running fine. When I finally started it, instantly started knocking. Thought maybe it was the lifters. I removed the valve covers all the spark plugs. Turn the engine over by hand, checked each rocker arm, and they all were tight. I went to pull the dipstick out, and it was stuck. I pried it out with a prybar, and the end of the dipstick was bent and a curve almost 90° at the tip and I could see marks on it to where it had been striking something on the crankshaft.

Check the oil in it, Then look for burn oil or shaving in the oil. If there is sufficient oil and no shaving or excessively burn oil. Then fire it up check for oil pressure. Once everything is done go from there buddy. You will know if something is about to come apart after a few seconds of running sir

@@autoguydiy4244 man I drained the oil, it was black. The oil pan gasket was about in pieces. I put a new oil pan gasket on it took the filter the little tube that comes down off the bottom of the oil pump to get off it had a bunch of gasket pieces all over at mats are cleaned it off checked all the bolts and everything to make sure everything was still right

Sweet . If everything is good fire it up and see what you got sir

I got a sound on my dads race car and he has dementia now so he cant really help anymore but its only on low rpms. Give it some gas and get the rpms up and it goes awat and its at the top side of the engine. Its a 406 sbc with a 6-71 blower. I wish i knew more about cars man i wanna get it running for him

[@autoguydiy4244]

Sounds like a lifter losing pressure

[@JeremyStaszak]

@@autoguydiy4244 thanks for the advice. I'm not sure if it's in the blower or not so a friend suggested I take the belt off the blower and start it to see if the sound is still there or not

Nice video. I have a straight 6 BMW. When it gets to operational temperature it kinda knocks at the oil pan. Knocking gets faster when revving. But. If i restart the engine, knocking is gone for a time, then it starts knocking again. What is even more strange is that if i let it idle for some time, i can hear some valve to operate from the enging bay, hiss huss, knocking is gone. Do you have any idea? Thank you

[@autoguydiy4244]

Thank you

[@autoguydiy4244]

I'm not to sure buddy. I believe the rod knock could be a slightly worn rod bearing. The noise from top put your belt and check some pulleys. They can make terrible noise when going out

i hope god has been blessing you this video is so helpful thank you so much

[@Gersberms]

Thanks! Can a rod knock go away after the engine builds oil pressure? Or does that only happen to lifters? I have a V6 that knocks for 1 minute after it hasn't run for 8 hours. Any sooner than that and it doesn't knock.

[@autoguydiy4244]

It sound like your loosing oil pressure around the rod. There is a very thin line of oil between rod and rod bearing

[@KageKageKage]

Would the rod bearing be something you can feel knocking near the gas pedals or in the drivers area?

[@autoguydiy4244]

Yes sir you would feel o It through the pedal if bad enough

[@KageKageKage]

@@autoguydiy4244 what if it’s above the pedals but below the steering wheel?

[@autoguydiy4244]

That sounds more like a cracked flex plate

I have a 08 ram 1500 and it always starts knocking when the engine has already warmed up.

Piston slap changes everything because it sounds like both?

Good job brother I will be checking in the morning thanks

I got a question. My truck suddenly had no oil in it. It started to I believe knock I put oil in it and the knock went away. How much damage did I potentially do and should I park it permanently until I get the engine pulled

[@autoguydiy4244]

How does the truck run

[@Motomonk420]

@@autoguydiy4244 now that there’s oil back in it, it sounds great. I don’t hear any knocking.

[@autoguydiy4244]

@Motomonk420 If it run good drive it. If there was any significant damage the knock would still be there. Are the truck would run like crap
