What's inside a 500,000 km Toyota Engine?

Ever wonder what's inside an engine with over 300,000 km?
In this video we teardown a Toyota Prius 1NZ-FXE 4 cylinder engine from a 2004 Toyota Prius. The engine features drive by wire throttle body, cast aluminum intake manifold, aluminum head and block, dual over head cams with variable valve timing on the intake, an accessory belt for the water pump only, and a timing chain powering the two camshafts.
The Prius engine is the detuned version of the 1NZ that makes less power but is more efficient because it runs on the Atkinson cycle.
After removing the oil pan, timing cover and valve cover it is evident that after 17 years and 300,000+ miles the engine is tarnished dark on the inside. The oil control rings are clogged, and carbon buildup is evident on the piston heads. The bottom of the sludge and oil pickup is lined with sludge. The intake system has carbon buildup from the PCV system. In conclusion, while there is no evidence of mechanical wear just due to high mileage, the lesson learned here would be to take care of the oil system in your engine if you want it to last longer than the rest of the car.

It was on the Prius C in the USA from 2012-2018. I have a 2013, bought it last year before car prices went crazy in America. Seeing videos like this makes me wonder why anyone would buy something other then a Toyota, especially a hybrid car.

@@benistingray6097 Hi, same question as before but with Honda? How much difference is there between Toyotas and Hondas? From your experience

[@benistingray6097]

@@MHNK77 Hm their both really good but i would still rate Toyota higher. We had more "non service" work with Honda, mostly small stuff that broke, for example the Honda Jazz always had problems with the EGR systems clocking up. Also i would say Toyota is more servicable. The way the engineers build stuff makes working on them super easy which in return should make repair bills lower just because the work is done faster. But take that with a grain of salt, i havent really worked on Honda in the last few years so things could have changed. Also im only working on Toyota for maybe a year so i dont have the same experience as with Honda. You cant really do wrong with both of them. Best is to do your research on problems with the specific car and engine your interested in and avoid problematic things.

Most if not all workshop mechanics nowadays are called technicians. There's a big difference between a mechanic and a technician. Mechanics can take an old damage part and repair it from scratch. Technicians simply replace damage parts with new ones ie strip and assemble.

[@nerd1000ify]

Modern engine bearings are made in multiple layers. The back is steel, which is covered with a thin layer of either aluminium/tin alloy or copper/lead alloy. If copper/lead is used it will in turn be coated with a very thin layer of either tin/lead alloy or pure tin.

Toyota engines last. Great story: acquaintance had an 80’s Corolla. Drove in it for many years, then the oil pressure light came on. Drove to the dealer upset about the light, “fix it”. Appeared that he had done over 60k Mi (100k km) without ever changing and checking oil. They filled her up and off he went.

I remember almost 30yrs ago older lady came to my friends shop complaining her Tercel died. She drove for 60-80k km without changing oil. When my friend ask her when was the last the oil was changed, she replied: I thought the Toyota is so good and don't oil change. He rebuild the engine and she became his regular costumer.

[@SI0AX]

Not after breaking one of the timing tensioner chains. This vehicle is going to be junked, it was totaled somehow. Maybe the catalytic converter was stolen. The catalytic converter in even the oldest Prius is the #1 sought after thieves because they have the most rare metals out of any other car brand due to Toyota trying to go very low emissions with the Prius. It's so expensive that replacing the catalytic converter costs more than what the vehicle is worth especially with that mileage and many states don't allow aftermarket catalytic converters.

Question for Speedkar99 or anyone. I follow you and used ur video on my timing belt replacement video for my 97 Lexus es300 IMZ 3.0 motor. It’s been about almost 3k since the replacement. My question is I’m getting a almost like a higher pitched noise coming from front cam pulley. Any idea what causes this? It almost sound like the pulley is loose. I did take off the cover and inspected it and everything looked good. I used Asin oem parts from rock auto like you did. Could the belt be too tight ? The idler looked fine that was my first theory and the noise is coming from the front cam pulley and I didn’t change the seals. I have looked on forums nobody seems to know but suggest have it inspected. I don’t have the cash for it lol it’s why I done job me self. Any help be greatly appreciated!

[@speedkar99]

Use the stethoscope or screwdriver to pinpoint the noise while it's running. Could also be your accessories as well

[@markkauffman6184]

If the belt tension is too tight, it can whine like a supercharger belt. Go find a video about a Dodge Hellcat, inevitability they will be driving it hard and you can see if that is what your timing belt sounds like.

[@MTMabowels]

Thoroughly enjoyed watching this. Was the engine rebuilt afterwards?

[@matthewbowen5841]

As far as the sludge, these maintenance reminders from the mid 2000s caused Toyota lots of issues. They were still on conventional 5W30 and many of them on factory settings only called for LOFs every 7500 or 8000 miles. IIRC Toyota did an update to lots of cars from this era to shorten the intervals. Possibly related to the 2AZ oil burning.

[@putraadriansyah8082]

That's a really nice engine. What are you planning to do to the engine after video? Rebuild or use it for another video? Love the video btw

[@MegaHugro]

How does the hybrid factor into the mileage doesn't that allow the IC engine to not run as often and run off the battery or am I missing something here. Or put another way to the hybrid factor of the Prius skew the mileage high when the mileage really isn't that high on the IC engine?

[@speedkar99]

I mentioned at the end of the video. You have to outweigh the time spent running vs the wear of how many times it's been started and stopped

[@rkgsd]

In my experience, almost any engine approaching 300k will be burning a little oil no matter how well its been maintained. I'm referring to valve seats and piston rings. I've got a 1mz-fe with 260k. Synthetic its whole life and changed every 6k. It needs about a half quart a month if driven hard and over 80 mph. The valve cover gaskets are famous for eventually leaking on that engine too. They were just replaced and no leaks for now. A few seconds of blue smoke if started a few hours after an aggressive drive.

[@nerd1000ify]

Valve stem seals will often go before rings or seats. Then oil will be sucked down the valve guides by manifold vacuum, even if your rings are perfect.

[@TheNigaHigaFan4Ever]

you are absolutly right, we owned a corrola verso for 15 years, it was still driving good but we needed the oil just as often as you fill up with gasoline

I'm still better off economically paying $1500 for a battery install versus driving a non hybrid.

@@Toyeboy89 One thing to remember is that the engine of the Prius C is a modified version of the gen 2 Prius, and the C has proven to be more reliable than both gen 2 and gen 3 Prius. I would still use the engine oil the manual says, would not recommend using a different one. But indeed, it is better to change the oil every 7,000 miles instead of 10,000 miles, though it depends in the driving conditions. It is better economically to pay $1,500 for a new hybrid battery every 10 / 12 years, than it is to drive a conventional ICE and waste more money on fuel, and maintenance.

[@markkauffman6184]

What really surprised me is the camshaft area had no sludge at all, just some discoloration from the oil but down in the oil pan there was a lot of sludge and the oil pickup screen was basically clogged. It would be interesting to find out what kind of oil (conventional or synthetic) and how often they changed the oil.

This engine had a lot of start stop cycles, thus more wear then running same temperature all the time. So i dont dont agree on the comments it hasnt run the mileage, it has run even more like short distance city traffic!

Yes and no, the start stop is hard, but it runs more at higher speed than stop and go in traffic when hybrid kicks in.

It looks a lot better than a direct injection would with 1/5 the mileage.

[@speedkar99]

[@beaconbus]

Excellent video! Not sure I agree about the hybrid engines not having as much wear because they don't run all the time. My Prius engine runs 90-95% of the time and does alot of on/off cycles that I think might cause more wear than an engine run at constant rpm's. I believe we don't see much wear because Toyota makes well-designed and built engines.
