The coolant leaking creates a 'steam cleaning' effect, creating clean spots in the piston and especially the exhaust port area in the exhaust header point.
always get the head tested for valve leaks, i just did one recently and 12/16 valves were leaking bad. my machinist said these heads normally cannot be skimmed without some kind of special heating machine or something, but my head did not require any skimming from warpage

This job is turning out great. You did a great job filming. Using the abrasive pad cleans things right up. I like the way you used that old piece. It's broke in. I used Scotch Brite pad for years working on commercial aircraft. Trying to figure out how the head gasket failed. The owned should use quality fuel to keep that carbon from building up.

Thanks Peter. I had never considered the heat/cool cycles these engines go through. The plugins are probably the largest heat cycling with the larger battery packs increasing the engine off time between starts.
In my own experience 80s 90s era Toyota cars were probably the the most reliable cars because engines can be restore so many times placing only rings new in the New era engines the whole bunch of engine is replaced

Perhaps the problem with Prius engines is the fact they are off till you need to pick up speed suddenly and so the engine has to go from being shut off to high rpm in mere seconds. I've always been told that first you start the engine, give it a few seconds for the oil to move up and then you drive off at moderate speeds till it warms up. A hybrid engine does not have that luxury.
I’ve been driving prius for over 10 years now and currently have the current Gen.4 model and always wondered this, but I think oil pressure is established before the computer injects fuel and produces a spark?
This electric motor in the Prius has the ability to spin the motor before the ignition is activate Therefore there is no need to wait for oil pressure before going into high RPM like you might do with a conventional motor. The motor is already spinning from the electric motor and building oil pressure before the spark plugs even begin firing. The ECU is smart enough to know when the motor is in the right position and condition to begin the ignition system to start making power. This in part is why you don’t feel a sudden shock when requesting engine power with the skinny pedal
Have you ever looked at an original head gasket versus the replacement Toyota came up with? The original was terribly designed. That little thin strip of black sealer around the passage areas is too weak. The replacement gasket has one continuous layer of sealant across entire gasket. No ridges and valleys. Edit… he shows the revised gasket in the vid
I have a question about Toyota corolla xrs belt tensioner, my ex husband bought a belt tensioner for my car a long time ago never put it on, well my brother put it on the other day for me. The pulley is a bit bigger than the other one , how to know what size belt to buy
I was also under the impression though...that even in the Chilton and other manuals it says that Toyota recommends not to take anything off the head no matter what. They recommend that if it's bad enough and you can't just put a new gasket on it as well as to make sure its flat withtin spec that you should get another head...is that just rumor or something? Because others I've seen that do this repair have stated the same as you to always always always send it to the shop just to always make sure it's good don't take chances
I have an 2008 Prius the engine starting rattling noise then the white smoke 💨 came out of the Exauce pipe I found oil cylinder 2 and 4 also spark plug the tip of the head had oil on 2 and 4 any idea 💡 what might happen or how to fix it
Hi Peter, maybee you can help me too? We have a Rav4 2001 with 1 AZ-FE. It has ~90.000miles on it. I have a issue withe the vvt-i. OBD says P1349. Ah yeah the OCV... i changed it 3 tirmes with different new (o.k. not stock ones). After ereasing failure it´s comming back, but later not right after start, after several miles/days. Motor is running smooth nothing loud or anything. So opend valv cover and checked timing - also fine. Changed Chain tensioner (was leaky) nothing better. Did the activation test on the ocv when idling, motor stalls, so vvti system o.k. Puh what else can cause the (somtimes intermittend) P1349 error? Oil changs we did, it´s not perfect but not dirty. Changed camshaft sensor - same. is there a chance to log data with techstream to see when and maybee why it happens? Thanks Thorsten - Germany
While it has nothing to do with this video, I'm unable to get into programming for a 2014 Corolla. I have a Autopropad and connection fails everytime. It also won't go into onboard programming either. Help???
I'm just beginning to have an issue with my 2010 at 145K. My question is, what is the long-term success rate of the replacement head gasket? I don't really have a mechanic locally I'd trust to do it, and I don't want to get it done only to have the same issue in a year or two. My Prius is otherwise pretty much bullet-proof. I'd get it fixed if I knew I'd get another 100K out of the thing.
So it looks like the gasket is rubber coated aluminum, and the rubber broke down and started leaking. So why don’t they make the gasket out of aluminum or copper or a high temp gasket like hydraulic cylinders use, some thing that’s not going to deteriorate and start leaking??

Opinion: have 2013 Prius with 180,000 miles. I change oil every 5000 miles, changed fluids as recommended. Want to get another 100,000 miles out of car. I been thinking of replacing head gasket soon before it blows out, within next 10,000 miles. Going on a 2500 mile vacation soon. What do you think, good or bad idea?
Do you service your systems on time according to schedule? Sounds like you do. Especially coolant. Most people don't and let the system go low or become corrosive and eat itself out. Why do something you don't need? Unless you were going to drive through the Sahara without anyone around to tow you to a shop, I wouldn't. Unless you've overheated the engine, save your money. Follow the maintenance schedule as instructed. If it makes you feep better you can do two things. One pressure test the cooling system to see if it leaks or loses pressure. That can mean impending failure. Next time you have the heads exposed like in a valve cover job, have them retorque the head bolts. And three, if you have bad luck, research where some GOOD mechanics are on your route.. and not the stealersaop
Sell it before the head gasket blows. Toyota wants $3800 minimum. There are good shops out there that specialize in Prius head gaskets and they are around $2000-$2500. This is not a maintenance issue. This cannot be prevented.
@@Herlongian Thanks for reply. I would sell the car if I could purchase another car at a fair market value. Regards to cost, I am a shade tree mechanic and I can change head gasket, replace water pump and clean egr system for around $300 in a day.

Mine blew at 168,000. Car never overheated, maintained to Toyota specs, yet the head gasket failed. The shop does one 3rd Gen Prius head gasket job after another. There were 3 in the shop ahead of mine. $2200 repair that Toyota should pay for.
How come 2nd gens don’t blow their gaskets? 3rd gens also suffer inverter failures. My 2013 Prius V, well maintained, has had both fail. How is this reliable? Toyota is covering inverter repairs on ALL Prius V 2012-2017. That’s everyone built.
Not a whole lot, old age catches up with everything. But most people don't change their coolant at regular intervals, so there's that. And also avoid engine overheating at all costs - it can warp the head and/or 'cook' the gasket.

@@davidfalgout7304 agreement with what Matt said but also if you ever overheat, you have a secondary radiator in your car with a powerful fan. You might have guessed already by the time you read this. But it's your heater core. Not only are you sucking more hot air from your system by putting on max heat and turning on the fan to high, the two fans on the actual radiator kick on as well by default if they're not on already. People don't watch their temp gages like race drivers do. And they don't have to as much as they do but do it more than most do especially on a third gen Prius. Yes the inside of your car will get hot and fast. But you have windows that roll down and also you don't have to aim the vents at your face. They point other places too. Like away from your body.
This problem cannot be prevented. This is either a design and/or a manufacturing error. Toyota should pay unless their cool with their engines blowing head gaskets at 160,000 miles. Were talking engines that have never overheated, no warped head. Some say stretched head bolts from on/off heat cycles occurring so often. One mechanic said when he removed the head bolts they squeak making him wonder if the threads were lubed. If they threads are not lubed, an incorrect torque could happen. Some say the gasket itself wears out from the heat cycles. Mine blew at number 2.
Bad design and manufacturing of Toyota. My Chevy Volt hybrid has 262,000 miles and the head gasket is just fine. It’s mainly been run on gas and not plugged in. Hopefully 5th gen Prius fixed this head gasket issue. I know 4th gen is already starting to have failures too.
Why is this happening to thousands of early 3rd gens? Mine , a 2013 Prius V, blew at 168,000 despite never having an overheat issue and all maintenance performed as scheduled.
It’s because, with being a hybrid, it turns on and off all the time so the engine heats up and cools over and over, so 200k on a hybrid is like 400k on a regular engine. It’s just an issue from the gasket expansion and contraction so many times.
Wow this guy seems like a rookie. This seems to be the first time he has witnessed the effects of a blown head gasket and yet he is teaching auto mechanics. WOW
Yeah just ignore the years and tens of thousands of hours of work and hundreds of head gasket jobs. He's also not teaching any auto mechanics. He's showing DIY people how to get their repairs right. This is just his way of demonstration and adding dramatism to his videos. It's his filming style. Hardly a rookie. He's worked on diesels, Corvettes, Mercedes, Subarus.
