During the winter I frequently do short trips in -35C weather where I live, but also regularly do 8 hour non stop drives. For that reason I do oil change intervals at 5000 km (3000 miles), and run 0w20 in the winter and 5w30 in the summer when it gets to +30C

You don’t need them on these engines. Port injection keeps the valves clean and there have been companies that refuse to make a catch can because they’re incompatible with the integrated PCV design on the T24A

Sorry to hear that. What’s your build date? Mine is 5/24 and I’m in the VIN range for this TSB, 80k km and no issues thus far…

This is exactly what my maintenance schedule looks like. 30w in the summer can't hurt anything, especially if the truck is being worked hard. 0w20 won't hurt anything either (assuming no fuel dilution), but there is a lower safety margin before it shears or dilutes out of spec. Being a turbo GDI...

I just did an oil change at 75,000km with 5w30 for the summer heat, and wow there is a massive difference in how quiet the engine is at idle. Oil pressure is the same as 0w20 throughout the RPM range once it is up to temperature, but slightly (less than 1/4 of a bar) higher when it is cold. I...

Oil pump on the T24 is driven off the balance shaft directly via metal (polymer coated) gears. It's the large part under the crankshaft that kind of looks like a twin scroll supercharger. Overall a very robust design IMO

I did both diffs, xfer case, and MTF at 50,000 km (30,000 mi), the rear diff magnet had some small shards on it, and the fluid was clearly very worn. MTF, front diff, and xfer case (used very frequently) looked super clean though. The rear diff takes a majority of the beating when daily driving...

I agree, it is very strange that all these companies are trying to sell their aftermarket big turbos but no body is posting the actual performance numbers. This video he states that it is capable of 500hp which I find really hard to believe. I would never drop $5000+ on any of these kits if I...

MT90 every 30k miles (50k km) and you won't go wrong. Use whatever 75w90 is cheapest for the diffs. Transfer case uses Redline MT-LV.

The best air intake for these trucks is the one Toyota put in from the factory. I’m fine sacrificing 15 whp for much better filtration. Years ago I played around with the K&N oiled filter in a Civic Si I drove. It really made no difference in power, and I was constantly cleaning oil off the MAF...

I used Redline MT-LV 70W75 for my transfer case and Redline MT90 for my MTF (GL4 - VERY IMPORTANT) The Redline website lists it as an alternative to Toyota OEM 75W (stupidly overpriced). It is GL4 (MUST HAVE for MTF and Xfer case fluids). For diffs I used Valvoline 75W90 GL5 (GL5 is only fine...

If it's not getting into boost at all under high engine load then the turbo wastegate isn't actuating properly. Is the vacuum line to the wastegate popped off or clogged? It should begin closing the wastegate under load (high vacuum) and sending boost into the motor. Look in your engine bay on...

I wouldn’t want to raise the redline either. The chief engineer has stated crankshaft hammering issues on the 6MT above the stock redline, and I find this motor makes all the torque I’ll ever need below 4000 RPM. I used to have a Civic Si and my days of wringing out the engine to 8000 RPM are...

Hello, I am wondering if there is an option for the OTT tune to only remove the rev hang from the 6MT equipped Tacoma. I don’t want the whole tune for the engine, the only thing I want to change is eliminating the rev hang. I don’t feel the need to overstress my engine and squeeze every last HP...

Fair enough. There is no reason to assume 5w30 would protect any better than what the engineers tested the engine with and approved it for (0w20). I’m just saying if I do both oil analyses and the 5w30 shows less wear materials on the same OCI and driving conditions, that would convince me to...

Someone running 5w30 should post their UOA! If the test shows improved wear performance over 0w20 UOA’s taken at the same OCI and under the same driving conditions, then we will have an answer. I’m planning on switching to 5w30 this summer for one change and getting it tested, and testing the...

Great, thank you. I assume this is what the maintenance manual is referring to when it mentions putting the water control valve in injection mode. I wonder if it is Water Route Switching Valve #1 or #2? It seems like they purposely make this a pain to do DIY...

A little late to the conversation here again, but I am wondering what the special function looks like to actuate the water control valve to injection mode. I am looking at the XTOOL D7S, but I am not sure if the Special Functions change depending on the make and model. It seems like most reviews...

I am looking to buy a XTOOL D7S for this exact purpose. It seems like all the reviews on it show that it has the capability to actuate the "Electric Pump", but I would imagine the special functions on the scan tool are different depending on the make and model. If anyone with an XTOOL scanner...

I am coming up on my first coolant change interval, and I want to do it myself. I am worried that it will be a PITA to do with this new coolant system. I read somewhere that you need a bidirectional scan tool just to change the coolant properly! I really hope that isn't true and these trucks are...
