Electrolysis has nothing to do with the head gasket failing or engine overheating. If he meant electrolytes, that’s just referring to the ph balance of the coolant in regards to it’s ability to carry a current, or allow metal to react by oxidizing (rust).

Awesome explanation. My 2010 prius has about 350K miles on it. I got the cylinder 1 and 2 misfire. I did the chemical test and it confirmed that I do have a blown head gasket.

Still debating on if I should just do the replacement myself.

I'd just get the head gasket done if you plan on keeping it. I used the thick silver Barr's Leaks and it lasted 10k before needing more. Lost a water pump not too long after the 2nd use but the car had like 220 thousand miles so it may have been going anyway, that's normal time for that type of part. Though after my 3rd sealant use the heater core clogged. Now it sits in the garage needing 4k in work, though still runs fine for short trips, just no heat.

Why are you not mentioning the NEED to check for a bent rod? This is a 13 to 1 compression engine. Doesn't take much coolant to lock it up. Mine had a #1 bent rod, luckily I CHECKED. I replaced with a Gen 4 eng. Much better Piston and ring design with minimal conversion

[@mendelleisk4577]

Maybe clogging EGR system is a big factor too? 3rd gens are the first to have this system, and it appears to be woefully under designed. Cross-sectional area insufficient, and the intake UPSTREAM of the Catalytic converter. The EGR cooler slow-but-sure clogs up with carbon, ditto for the valve, the pipe, and the small EGR passageways in the intake manifold. Proper flowing EGR is paramount for keeping engine temperatures in normal range. As it clogs, the temps go up. Which probably accelerates the carbon build-up, and overly stresses the head gaskets.

[@gasketmasters]

The clogged EGR is a result of temp fluctuations.

[@mendelleisk4577]

@@gasketmasters Well, that's debatable. 3rd gen is first to have this "mark I" EGR, and also the gen where the head gasket are failing in such large numbers, and so early. For 4th gen, they've pretty much DOUBLED the cross-sectional area of the EGR, and revised the intake to be downstream of the CAT.

[@peterasher2609]

@Gasket Masters The whole purpose of having EGR is to lower combustion chamber temperature. The lower temperature reduces NOx emissions. If the EGR is plugged up, the combustion chamber temperature will shoot up making the engine temperature cycling more extreme. And your explanation of the gasket failure by temperature cycling fits the timing of having the gasket fail after the EGR stops working.

[@sklyrovka]

Yeah, I agree. The biggest difference between the two gens (2/3) is the EGR design. I don't buy the explanation in the video as the root cause of all of these failures.

It shouldnt be a frequent occurence if it is then there is something wrong or gaskets installed are very bad. If its designed well it should last for at least 300-350k miles. In Prius main problems are both design (too narrow gaos between cylinders and open deck design) and hybrid system which doesnt let the engine fully heat up and keep the temperature.

[@rondhole]

Gasket Masters, It is a really good explanation and agrees with metallurgy. Toyota should put more money in research and development of head gasket for their Hybrids. Through alloy formulation, layers optimization, and annealing process, optimum gasket properties could be achieved. In Europe 70% Toyota sold as hybrid in all cars (Prius, Corolla, RAV4, Yaris, Camry, Highlander, ES,GS,LS,RX). Do you have enough statistics for reliability on 1.5 L (Prius C), 2.5 L and 3.5 L V6 Hybrids in Toyota?

I would suggest using the Bars head gasket sealer before it starts to leak and leave it in. I posted a comment today about using the Bars on my prius.

[@SayNoToGravity]

Would you say Hybrid cars are not worth buying because this problem?

[@repairvehicle]

Very interesting. Why second gen prius don't have this issue?

[@mylesgray3470]

2 reasons off the top, 3rd gen has an electric water pump and when it suddenly dies, so does your head gasket due to overheating. 2nd, the 3rd gen has an elaborate EGR system prone to clogging leading to excessive cylinder temperature. Both of these are serviceable items. I addressed both on my car as preventative measures at 125k.

[@repairvehicle]

@@mylesgray3470 clogged up egr system has nothing to do with excessive cylinder temperature.

[@mylesgray3470]

@@repairvehicle This is the theory on PriusChat. Nobody has proven it definitively it, however a clogged EGR system has strong correlation with head gasket failure including manny repeat failures when the EGR system was not cleaned when the head gasket was replaced. Could be from temperature, pressure, or both, that’s an ongoing debate but the relationship to head gasket failure is quite certain.

[@repairvehicle]

@@mylesgray3470 , egr has nothing to do with head gasket failure, it's a nonsense from people that don't understand how egr system works.

[@repairvehicle]

@@mylesgray3470 , what I have found. Head gasket fails from to many cycles heat no heat. Metal can take so many cycles before it fails. Head gasket is made from Metal. Egr cooler designed to cool off exhaust gasses before they are routed back for burning inside cylinder. Only partial gasses enter combustion chamber at given times.

Best explanation ever! Is there someone you guys can recommend around Greenville SC?

[@alexpimentel9554]

Thank you for your knowledge.I brought mine to a Toyota dealer and they still didn’t know until the 3rd time it went back and finally said that the coolant was leaking in and that I would need a new engine. Is it to late to get the gasket changed out once you start hear that knocking?

[@kenshoenso3038]

[1:35] You know these guys are about their business the way he took that gasket out 👏 With all you just said, because this wasn’t an overheating issue due to auxiliary parts (water pump, thermostat, etc.), would you still recommend putting all these components in new?? Getting ready to do this for my friend but trying to save them money and just do the essentials (all new gaskets, head bolts, coolant etc.)

[@rodneyispro]

I took my 2010 Prius to a Toyota dealership ( stone mountain Toyota in Georgia ) they said it was my intake manifold, then my coils, so 2 grand later they still didn't know what was wrong with it. They then have to run diagnostics twice for 4 days. which they provided a rental for those days as if that really helped. But then come back and tell me I need a new head gasket (3.5k after taking 2k off for the stuff I already had done) after I spent 2 grand and have no more money they tell me this. So now I think I'm going to get a loan, call gasket masters, and drive 9 hours to Florida. =)

[@angelinaolivas1720]

That why I always pay with a credit card you can dispute that and get your money back but it's probably to late.

[@sueellenmcgoey8708]

Who do you use in Florida. I'm just starting with the 20 second rattle on start up😢

[@steelerchuma4192]

Thanks for the info man you rock 👊. I've been having issues with cold start rattle when the car sits for a few days, despite changing the hg 40k miles ago.

[@ucakpan]

You might be referring to the brief rattle on a cold engine that's present in many Toyotas caused by the intake camshaft timing gear assembly. I'm aware they've issued TSBs for this issue, specifically T-SB-0087-09 for the 2ZR engines for 2009-2010.

[@kens97sto171]

Also check to see if your spark plugs or coils are bad. I know my Prius definitely vibrates a bit more at cold start after sitting overnight. Relatively easy thing to swap and see if it fixes it

[@sueellenmcgoey8708]

​@@ucakpan that's happened twice to me. Should I be concerned? 2012 185k

[@ucakpan]

@@sueellenmcgoey8708, do you mean twice failed head gaskets or twice you heard the cold start rattle? If it's the latter it means it isn't a serious issue (unless it embarrasses you). If indeed you refer to cold start rattle then try this: start up the car when it's cold and listen for the rattle - if you hear it, good. Shut down the engine then start up again immediately. If it's because of the camshaft timing gear issue you won't hear any rattle the second time. And if you've confirmed the above test to be the case, I'll tell you something: many people are driving their cars with it because it's not affecting performance and isn't an urgent problem. I've driven mine like that for about 23,000 km (~14,300 mi). It is not an extremely complicated fix but the OEM part isn't going to be cheapest ( toyotaparts.mcgeorgetoyota.com/oem-parts/toyota-engine-timing-camshaft-sprocket-130500t050?c=cT0xMzA1MC0zNzA2MA%3D%3D) I presume you refer to the 1.8L engine

[@steveolive9991]

Fel-Pro, a gasket company, used to make a Teflon-coated head gasket that allowed the cylinder head to slide on as the cylinder head expands and contracts.

[@grozacompany1989]

So I'm getting all this symptoms, but no coolant loss, and compression is even across the cylinders. 150/155/160. Started with P0300, P0301 P0303. New egr valve, recent PCV valve change. Now intermittent rattling at lower rpms. Cylinder 2 misfire but not enough to throw CEL. 2013 prius 274k miles How do I make sure it's a Headgasket failure without going to the shop???

[@donaldmontgomery9340]

Go to your nearest auto parts store. Rent a “combustion leak tester”. It’s a plastic tube that has a cap with a hole on top to fit a suction cup or rubber hose, and a cone with a small hole in it on the other. Pour a small amount of the included fluid in the tube and cap it off. Remove the reservoir cap and put the cone on it. Have an assistant start the car. (If the car is in ready mode, have the assistant give it just enough gas pedal to kick the car on, or turn the heater on high temp, high fan). Draw a vacuum on the tube and watch the fluid color. If it changes, the head gasket is blown.

[@The415Sco]

If this were 100% true wouldn't second generation Priuses also be prone to headgasket failure? The consensus in the Prius community has shown that head gasket failure is almost endemic to the third generation 2010-2015, but even less so for years 2013-2015 due to numerous revisions in 2013 including EGR/Intake Manifold design changes. What are some of the differences between second generation (2004-2009) and third generation Priuses you ask, well most importantly the second generation has no EGR system that is prone to clogging or failure which has been witnessed very commonly in the third generation leading to changes in internal temperatures.

[@paulgoudfrooij6561]

The 1st and 2nd generation have a different engine which seems to be less sensitive to the leaking of coolant into the cylinders when the head gasket starts wearing

[@selvaspk2324]

How do I prevent Failure? Replace it before it fails?

Hey gasket masters, I just bought 2012 Lexus CT 200h. After putting 3k miles I started getting rough cold starts and p0302 cel. Replaced spark plugs and check engine return and went away. How would I test a bad head gasket in a hybrid. I don't get milky oil, I don't lose coolant. If it's head gasket do I need to shave the head? Mechanics say I don't need it if it's even.

The high temp is the engine killer, hybrids have a most problems with a bad head gasket is due to poor/ faulty electric coolant pump...

Yep. Replace it and coolant every 100k miles with a new OEM unit and this shouldn’t be an issue. I did mine at 125k. They seem to fail between 100 and 175k apparently.

[@bbracing3925]

This issue seems to be prevalent in the 2AR-FE as well. My mother's 2015 Camry (Very well maintained & not beat on) without warning, it blew the head gasket at 38k mi. The only DTC's were P0302 & 303. (Important for her case study). The Local Toyota dealership ran their diagnostics and maintenance history, and pushed back trying to deny the manufacturer warranty claim for the "H.G" due to in her maint. history, she had got her oil changed a few weeks before (Late June) by an "express" style oil change franchise, and they used 5w-20syn. Toyota tried to deny the claim because on the oil fill cap it says 0w-20syn. 😂 Too bad it states in her camrys owners manual, that during spring/summer months, it's 100% safe and suitable for the 2AR-Fe. I stepped in on her behalf, as a certified Auto mechanic, my first question for the head tech of the warranty & service department was, "were there any VVT, cam/crank correlation, EOP DTC's current or stored?" - No. "Was there any coolant temp. related DTC's?" - No.........😬 "So just the 302 - 303 misfire's?" - Yes.......😳 Umm you might want to contact your superiors at Toyota global warranty center. 🤔 - 20mins later he came back saying, "Her claim was approved finding her clear of any cause of failure & set her up with a free loaner car until her Camry was repaired. Nobody is going to rip my mom off on vehicle repairs, damn sure not the dealership! 80k since the repair and it's been ok. Now just yesterday it set a P0420 🥴 fml😅

[@noseefood1943]

I always wondered why block and head can’t be a single piece. The pressure, heat and gas plus the stress on bolts are all because of the two pieces bolted together.

Which generation of Prius have less chance of head gasket failure?

[@piperpilot26]

It all depends on the type of driving. There is a current 2019 Prius prime owner that uses his vehicle for medical deliveries. He has just over 500,000 miles on the car and hasn't had any issues. The reason? 90% of his driving is in the highway where the engine stays running the majority of the time So there are less heat cycles.

[@ChuckStewart]

I have 04 Prius with over 300,000, never had to do a head gasket, also a 2010 with over 200,000. Also no head gasket problems. Biggest problem for 3rd gen is the EGR system. I just cut a piece of metal and blocked it off

The head gasket I used was Ultra-power from Rock Auto and the head bolts were from them as well. They were Apex. Any ideas?

[@rondhole]

Use only genuine Felpro. It works great on my 2002 Altima and last 70k miles or more since * sold it at 130k. Nissan head gasket Also inferior than Felpro. Toyota also revised it in 2013 Prius but not as much cushions as Felpro on the hole lips.

[@gasketmasters]

We only use Felpro. However. Your problem might have been an initial overheating issue. Many times people change head gaskets without addressing what may have caused the initial problem. Radiator, water pump, thermostat, could all cause the engine to overheat; there by, causing even a brand new head gasket to fail due to heat and compression of the thin metal.
