2TR-FE Reliability

There is no down side .The 3RZ FE is derived from the 2RZ FE (witch is more dependable and reliable than a 22re),and its the same design but the 3rz is a 2.7l vs a 2.4l in the 2rzfe. Nonetheless, the 2TR FE is derived from the 3rz except nearly identical design except it is has a VVTI HEAD. Reliable on proven technology,My 2rz fe tacoma has 380,00 regular maintenance, nothin wrong with the engine.

 

I have a 2005 4 cylinder which is the 2TR-FE motor. Not sure if any of you guys have this old of a truck,but there's two things I've notice if you don't take of it, it'll cost you a lot more later to fix. Exhaust gas recirculation pump when it goes out exhaust gases backflow overheating rubber and plastic parts causing a fire! Plastic bypass heater tube will self destruct over time and leak out all of your antifreeze! Temperature gauge won't see it overheating cause the sensor is located top part of the engine block, it only senses water!

 

Just FYI the 2005 is a 2TR-FE

 

That happened to my 2006 and thought it was because I mixed Prestone OAT antifreeze with Zerex HOAT antifreeze.

 

Hopefully you caught it in time!

 

Thanks for the heads up. I will change coolant at 100k mi and every 50k mi theteafter, using genuine Toyota super long life, strictly per Toyota maintenance instructions.

 

242,000 yesterday.had to change the valve cover gasket and the plugs 2 times.burns no oil still.

 

Caught what in time?

 

Zerex "Asian" Hoat is fine to use, you just don't want to mix OAT with HOAT antifreeze.

 

Well knock on wood.... My 2TR has had light Rod Knock... my own doing.. and with some heavier oil, some of the knock has gone away... but its still there. It's been 5,000 miles and my motor hasn't blown...

 

You didn't change the oil? Or did it rev like a honda?

 

While on the subject of where things are made, scroll to the U. S. map and click on a state of your choosing to see what Toyota is doing there:

Nah, I change my oil with the factory weighted synthetic oil every 5K miles and yes, I've rev this motor out pretty hard on my way to vegas on the 15 plenty of times...shit went down when I removed by fender liners to accommodate the tires and went into a mud pit much deeper than I anticipated.... the stock snorkel system became a massive straw and took in the mud all the way past my throttle body.

Needless to say, I must have blown my valve seals or burnt my valves with debris on top of frying my bearings - since I only have 130ish psi compression in the cylinders and it now ticks. I haven't done a leak down but at this point... don't really care about that...


Here's what happened at the mud pit....

 

Ru Roh! Looks like you fucked it good.

 

Looking at the picture you are lucky that it is even running at all.

 

Ever heard of motor hydrolock?

 

Yeah, I call it being lucky!!! When I went through, I had the CEL and the motor was stumbling, barely keeping idle. Once I opened the hood, it was like...WTF... took care of the CEL by cleaning the MAFS with water and a pick to get all the pebbles out and got it towed. Once at my shop, flushed the oil 4 times - in doing so, found silt contaminated in the oil. In between the oil changes, I was experiencing the low oil pressure light upon the engine stumbling.

Fast forward to now... changed the plugs, 2 more oil changes now, new air filter, cleaned the MAFS with the PROPER cleaner - and BAM, excellent idle and still runs! Yeah, the truck doesn't pull anymore from 3500 RPM but the 35s and the armored bumpers don't help either. I was planning on driving this until the engine creates a window...

 

A better shot - just shows how tough the 2TR-FE is all about!!!!!!!!
