Intermittent Engine Noise Is In Fact What The Dealer Said It Was! 2015 Toyota Prius

[@sheerwillsurvival2064]

If you use a transmission funnel it makes getting bore scope easy to get into cylinders

[@GlennManchester]

It's that easy huh dammit man why did that idea not come to me ? Lol and it is bore scope ? Not boroscope as it's pronounced by Kenny I have only used one half dozen times but never actually knew the technical name for it I said hey lemme borrow your camera brah ..

May or may not be worth fixing. Good job find the problem Ken. Don't burn yourself out trying to get videos out. Post them when you have interesting stuff at whatever time you feel like. You and your family are top priority.

Fix an engine with well over 300,000 miles, are you nuts?...

[@michaelszczys8316]

Maybe he wants to see if it will make 400,000

[@scottsorgea2567]

Pine Hollow Diagnostics had the same exact thing on a Prius and it was a head gasket that would only leak after the engine was warm. Pressure test when cold did not leak, but leaked after engine was hot. Ivan replaced the head gasket and it fixed the problem.

[@jthonn]

It's like throwing dice.

[@GlennManchester]

Ivan you must fix Toyota vehicle for vodka and cigarettes!!

[@grandcrappy]

​@@GlennManchesteryes. Weektor, where is wodka!

[@jfv65]

I'd say remove the head before pulling the trigger on a different engine. Btw my Lexus ct200h has the same engine. It also popped a HG according to the maintenance records that came with the car.

[@jthonn]

@@jfv65 If you do it yourself, I say yes and agree. If you are paying a mechanic, that is money towards a new engine. Remember that it is a hybrid and batteries are a small fortune. Just too many miles for all of that. How good is the tranny? Also the car has to be in perfect shape to even consider. That is my opinion, but the owner may have deep pockets and feel different.

[@stephenmeeks684]

If the engine gets changed, consider sending the engine core to Eric at “I Do Cars” so he can do an autopsy on KZbin for us.

[@haneyoakie14]

Eric does some great stuff. He is Saturday must see tv at my house.

[@zfunk9]

Why should he do that? If he wants to buy it let him pay for it and the shipping.

[@dentalnovember]

Yes!!! Let Eric tear it down and use old blue.

[@stephenmeeks684]

@ Well yeah, duh. But its only value is scrap value. Of course Eric should pay for it and shipping.

[@dontderockmerizz3211]

Kenny, I second this suggestion!

[@ericsherman4181]

It's almost always #2 and yes the engine temp matters, we probably replace atleast 5 engines this year, and our shop Prius is out back waiting for an engine LOL. Get it hot, pressure test over night and you will most likely see coolant in #2 in the morning. Good video and explanation! Usually high mile so we wont even bother pulling head. Find a used low mile and be done.

[@ToolsSNAPON]

Don’t get used engine, and other gamble. New short block and cylinder head, other 200k no issue!

[@jthonn]

@@ToolsSNAPON LOL, just go long block

[@jthonn]

Glad I read this comment, because I was going to say the same thing. With the mileage on that car, I would not have even spent the money trying to fix it. It's ready for the junk yard. Why? It's amazing it lasted this long, Put a new engine in it, then a cell goes bad in the battery, or the tranny goes. Sometimes it's better to know when to say when.

[@ericsherman4181]

@ it depends on what the customer can afford.

[@ToolsSNAPON]

@@jthonn lol, 2ZR doesn't offer long block!

[@dxxxm231]

Most likely just a head gasket. I work for a Toyota specialty shop and we do these all the time. Typically caused by clogged EGR passages creating high cylinder temperature.

[@lowbudgetbob1155]

Good to see you back, it means you're getting better. Hope Mrs. Wrenching is doing well.

[@WrenchingWithKenny]

I am! Thanks for your kind words. Keep wrenching 🔧 Kenny

[@johnaclark1]

It's a head gasket. Seen that exact symptom before. Very common in the Prius. I think book time is like 19 hours so it may not be worth it with that kind of mileage but it can be done in far less than that.

[@WrenchingWithKenny]

@johnclark the customer said no way to the repair with that many miles. Keep wrenching 🔧 Kenny

[@juliusglorieux8338]

Wow!! You are a great mechanical sleuth. Enjoyed this one alot!!

[@mckinleygoetz9855]

I'm glad the Borescope works for you. They do come in handy.

[@WrenchingWithKenny]

@mckinleygoetz9855 thanks again. I appreciate your gift. Keep wrenching 🔧 Kenny

[@jonjo6886]

Likely to be gasket failure. These things are started by a traction type motor and will bend connecting rod. They need fixing on first signs of a problem otherwise is off to Eric.

[@vipercrazy-9]

Scan car, pull cowl, unbolt and raise overflow bottle, leak down test the cylinder that has the most misfires, watch for air bubbles in the cooling system. If the vehicle has been driven a long period of time with the bad head gasket small chance either the block will be pitted between the cylinders and require decking or a bent rod due to hydro lock -very rare.

[@NSCnate]

My wife had a minivan once that kept dumping coolant into the oil. Pressure checked the cooling system and it held, but 10 minutes of driving and it was overheating. Turned out to be a crack in the head, that expanded when hot but sealed tight when cold.

[@kwgm8578]

Kenny, Amazing. When I worked on these beasts, not even doctors had endoscopes. We had to take the engine apart. It does look sweaty down there. Hope the family is well.

[@dross4129]

great to see you back to work Kenny

[@haneyoakie14]

2:35 good thing it has no sound if I was doing it, it would destroy the family friendly nature of your fine channel

[@robertlacob8831]

I would think that is a great diagnosis, Kenny. With that high mileage, I would only replace the engine with another low-mileage unit, if the rest of the vehicle is good shape.

[@WrenchingWithKenny]

I agree. The customer declined the repair. Keep wrenching 🔧 Kenny

[@ChrisTheBmxGuy]

Thats the way i usually diag head gaskets on engines easy to get to the spark plugs. I work mainly on CDRJ vehicles. I let the engine get up to temp and then turn it off and let it sit. Come back with my 1080p 3 camera bore scope (vevor brand from amazon.. like $40). Ive delt with a lot of headgaskets leaking only when hot. Good call though,

[@jimfiles3307]

Good morning Kenny, Stick with wrenching because you suck as a PROCTOLOGIST. LOL I thought you could use a good laugh.

[@WrenchingWithKenny]

😂 keep wrenching 🔧 Kenny

[@HamiltonSRink]

Remember: the EGR passages in the intake are quite small. The cooled EGR condenses in the EGR passages in the intake until one or more becomes blocked. When that happens, the blocked cylinders get no EGR, and the still open ones get too much EGR. Also due to the fact that the engine periodically shuts down, things cool down, aggravating the condition. The EGR cooler becomes blocked as well. The 2010 to 2015 Prius does this quite a bit. Repair: This only applies when not leaking coolant past head gasket. Clean or replace EGR, (oven cleaner, and/or lye soak overnight), Remove and clean out intake manifold and EGR passages in the intake manifold, new intake gasket and Throttle body gasket, clean head intake port area, reassemble. If your losing coolant, that must be fixed first. Due to the engine shutting off so much, and the resulting temperature swings, the head gaskets suffer on these.

[@WrenchingWithKenny]

Only 1 cylinder if affected. Keep wrenching 🔧 Kenny

[@MarkEye-r5d]

I hope that you are feeling better, can't wait for more videos.

[@curtisroberts9137]

I've never seen coolant leaking into a cylinder where it didn't clean the pistons to almost new condition unless it was cought super early. Looked like fuel to me. Possibly oil. I didn't notice the water drops. good catch. Coolant it is i guess.

[@walterboard-sf6tb]

Great job. I hope that your feeling better along with your wife.

[@WrenchingWithKenny]

Thank you for your kind words. Keep wrenching 🔧 Kenny

[@JeffinTD]

Nice video. Might be a case where an articulating bore scope would be helpful. Someone had a video where you could watch a drop form at the junction of the top of the cylinder and the head. The drop would repeatedly grow and run down the cylinder.

[@williamwelling4872]

Kenny you need a piece of white plastic pipe to feed the scope down it will help line it up easier for you

[@WrenchingWithKenny]

@williamwelling4972 You sir, are brilliant. Thank you for the tech tip! Keep wrenching 🔧 Kenny

[@keithrimmer3]

I hope you are feeling a bit better now Ken, they have a known head gasket problem with that symptom bud

[@billmalec]

Ivan at Pine Hollow said because of more heat and cooling cycles from the engine coming on and going off it is hard on the head gaskets.

[@WrenchingWithKenny]

@billmalec Hi doc! The customer declined the repair. I won't be able to get into it further. I hope you are well. Keep wrenching 🔧 Kenny

[@EvzenKovar-i5p]

[@garrettlindgren4626]

Would a cracked head or cylinder wall be caused by a manufacturer defect, poor preventative maintenance or just bad luck. BTW, glad you are back on your feet.

[@ericr2zz]

tape a straight piece of wood to the end of the boroscope. That will help get it in the plug hole.

One my sons has 2015 Prius 250 thousand miles on it when he bought it he had it about a month when he engine blew up 45 hundred to get it fixed this was 3 years ago so far it still running.

[@EvzenKovar-i5p]

The Car Care Nut, and many other channels, have often commented about Toyota’s Super Long Life coolant, and the implication the name conveys to Toyota owners. Namely, that the coolant never needs to be changed. I have a ‘12 Prius V. Toyota reinforced the whacky notion of a coolant that never needs to be changed by completely omitting a recommendation for service from the Recommended Service log book that they handed out to purchasers. My log book goes out to 120K miles with no mention of transmission or cooling system fluid service. Coolant becomes acidic with age and will eat away at the gummy substance on the HG, eventually causing a leak. A regular coolant tester won’t tell you anything about this. I bet a lot of Prius owners with high mileage have never flushed their coolant.

[@dontderockmerizz3211]

Glad to have you back Kenny. How’s Mrs Wrenching doing?

[@Aussie-Emlyn]

Re the borescope - yes you can get more rigid spiral spring ones (bend to shape) but maybe for yours use a short tube in the spark plug well to guide the camera in. Great tools.

I had a Ford Escort 2 1/2 years ago that had a cracked head on cylinder no. 1 and I bought a bottle of K-Seal and dumped in the radiator and the owner drove the car a couple days and kept an eye on the antifreeze and it sealed up and he has been running it ever since and he has put 5000 miles on the car with no problems, it's worth a try and you can dump it in with the antifreeze, no need to drain it and fill with water!!!!

[@edifyguy]

[@thomasgreene5750]

Fishermen in the Caribbean Islands have some pretty ramshackle boats with very poor engines. A trick they use to fix water-jacket leaks is to add raw egg whites to the coolant when the engine is cold and then run the engine to heat it up. Apparently, the albumen works into the cracks and then cooks in place, sealing them. It seems like a wild idea, but they swear it works.

What sometimes works in a third world country where every penny is pinched out of necessity, and what a garage in a first world country can stand behind as a legitimate repair, are two very different things.
