2014+ Toyota Tundra 5.7.

[Mikeeemo]

I change my fluid every 25 - 30k. Fluid is vital. I tow hard with mine, 9-10k pounds when I move the tractor.

Any one else tracking Cummings 6.7 is having RMS failures. It's junk.

Can't speak for the 2014 and newer but between my brothers and I, we owned Tundra Double Cab 5.7 2004 (350k miles), 2005 (300k miles), 2006 (mine 200k miles). There are no plan to replace them anytime soon.
Among the things we have learned:
* The starter is a beotch to replace but only the 2005 one failed because it was flooded.
* I don't care what Toyota says about sealed transmission and to not worry about the fluid. Drain and fill at first 60k and every 20k miles afterward is recommended.
* Toyota says don't change spark plugs until 100k and you can believe that. I changed mine at 150k and they still looked pretty good.
* Change the water pump when you change the timing belt if you want to save yourself some hassle.
* The Tundra got a turning radius of an 18 wheeler! It's always a struggle fitting in a parking spot, most particularly at my local Lowe's hardware store parking lot.
* If you rock back and forth hard between Forward & Reverse to get unstuck you may twist the Universal Joint off your drive shaft. When that happens, don't go to the dealer for a replacement. They want $900 for that precious piece of pipe. Find a machine shop that will weld that thing back and balance it for you. That will save you $700.

Other than that things are all good. Right now my brothers and I are targeting 500k before thinking about replacement. I used to want a diesel because they last a long time. These new gas engines are making me change my mind.

BTW, I'm not at all bashing any other cars or trucks. For all I know they are all good nowadays. The Tundra met my needs and I'm sticking with it.

The 5.7 never used timing belts.

I wont settle for anything but the 5.7.

Does my vehicle have a timing belt or timing chain?

But I agree with you when doing a timing belt, do the water pump.

Unless you are buying dollar store transmission fluid, 20,000 miles is a waste. I do mine every 2 years, which is 50,000 miles with full synthetic. I think i would pay the extra for Toyota atf.

RMS? What is that?

RMS? What is that?

From what I found looking around online, it appears to be rear main seal.

I wouldn't think a rear main seal makes an entire engine junk, especially a Cummins.

Agreed

Cummins are overhyped. They are living off of their name. So many other better engines to chose from that have more torque, bet better mpg and offer better support.

Cummings never had a good reputation for diesels, they were considered at the bottom of the list. CAT, Perkins, Mercedes, Detroit, others were preferred.

Cummings was never a quality engine, but Cummins is a good one.
