1989-94 non VVTI 1UZFE were all non interference.
I have a 92 SC400 hardtop, have had it for 20yrs. The engine has 303,000 miles, has never been opened, totally stock, as is the whole drivetrain. Drive the hell out of it, no oil consumption to speak of. On my 3rd timing belt as well as windshield. May be the best production car ever, is the most fun to drive___"Long distances at Hi-Speeds"
👍🏻👍🏻
Im stuffing one in a Scion TC Premium here we come baby
*laughs in S.A.R.D MC8*😈
Would you have to chop into the body for it to fit? Engine mounting?
They are only interference engines from 1995 and up. Great video! I am swapping one into my AE86.
ae86... my dream car
I was gonna say, I don't think the later ones are interference. Sounds like a sick ride you've got! I've been thinking about swapping one into my 280zx.
What ecu?
@@slowyota_rolla The OEM engine ECU has an immobilizer that is tricky to defeat. You need to either keep the OEM keys, or reset the Immobilizer and insert new chipped keys to bind them. Videos can be found on that process.
Does every version of it need periodic valve adjustments?
Only thing to dislike is how on VVTi models, to change the cam seal is a cam removal required job. It is a lot more complicated, more labor, and more opportunity to make an error going back together. The 2JZ engine with VVTi does not require intake cam removal for the seal replacement. They did the design better on it for service.
Great video buddy,Are you open to any LED lighting review? We just emailed you about that.hopefully hear back from you soon
90K for timing belt replacement.
I pushed mine out to 100,000 miles. When I changed it on my 99 GS, it was 24 years old with 103,000 miles. The belt was worn a little on the edges, and the timing marks and the Toyota writing on the actual belt were still visible.
@@gabrielsf70how was the replacement? I watched the video of 1uz timing belt replacement and it was quite frustrating.
@@NazIriz It's doable, however I found it difficult to seal the water inlet at the top. There's an o-ring, and then you use FIPG (silicone) to seal the square mouth joint. The water inlet is very difficult to re-install, and must be moved all the way back (hard to tell if it's "home"). Any mistakes, and coolant will leak down onto your new timing belt on engine start up.
You also have to get the belt and cam timing correct. There are videos on this (CartunesNZ), and the procedure is documented in the service manual. Replace the timing belt idlers, tensioner, and water pump while you're at it.
@@drrock5356 damn 😭 why they use a belt instead of chain tho..
@@NazIriz A timing chain has 1,000's of moving parts and degrees of freedom that can fail, along with more mass and metal-to-metal contact. A belt is lightweight, flexible, on single part, and has softer contact (less wear) than a chain.
Most of all, chains are louder than belts, which is probably the main reason Toyota spec'd a belt in this Lexus motor.
Timing belt on drive camshaft
Not thing else
Why would a vvti all of a sudden be high in oil pressure, have done oil sample allgood, have replaced oil pump with 3uz oil pump. Still high.
Normal OP with defective sensor?
@wholeNwon was confirmed with second sensor.
Have replaced oil pump, still high, guessing relief was faulty, now allgood
