Vijith555 's post May 3 2018 makes plenty of sense, explaining that the VVTi controller & locking pin vitally depend on correct oil pressure & that oil viscosity is crucial for this system to work properly, even worse if there's oil sludge. I'm currently looking to purchase a 50 series Aurion only 3 years old with 30K kms, services by the book with Toyota which states the use of 10W30 on first 3 services & last one done a few months ago using 5W/30 weight oil. The other day on cold start the VVTi rattle occurred for 1-2 second's 2 seconds after start/running. What I also noticed on RO Service receipts was that the 10W30 was "VVTi specific - Genuine Toyota Oil" & the 5W30 to be generic type oil ! Either this is one helluva picky system that favours one oil over another or the controller is still a reliability issue on these cars.

Don't let this happen to you ! VVTi Controller failure from a 2ZZ-GE motor. The bolts work their way loose & rattle noise begins, the controller cover starts to rattle, then the bolts break & cause damage, potentially catastrophic, especially when chains are involved. Lucky for me the missing bolts sheared off in bits & landed away from the chain drive & didn't get stuck anywhere. It punched a hole in the rocker/cam cover & that's it ! This high revving engine had done approx 250K kms when the controller failed. ps: note how clean the engine is :))

Rocketbunny Celica :) What's under the bonnet ?

"Guest" ? Toyota have gone mad, we're not guests, we're customers that make them lots of $$$$ . . . This is the problem with oil coolers, if you get a leak & then low oil pressure, you may as well kiss your engine goodbye. I wonder if this applies to all 2GR-FE motors or only those early model ones ?

2013 car ? How many kms done ?

The Aurion is already quite the fire cracker so I'd be inclined not to touch it either 😉

A detailers brush & a vacuum cleaner 😉

Odd, I would throw in 0.5-1L of Metho in tank say every 6 months. This will not only 'swallow' up all the water that might get accumulated in there but also give the fuel system a good clean. ps: get your fuel from another reputable station, preferably Premium 95, we're all heading towards it anyhow, might as well get used to it.

Wow !

A good mechanic is sometimes worth his weight in gold - almost. Well done.

Great that you persevered with this, odd that Techstream can't see the ABS module. Pretty sure my m8 mechanics scanner can see the whole enchilada on my MCV20R Camry (gen4) including Airbags yada yada. Where is that module located ? Great also that Techstream works on WINX - which version TS ? Cheers 😉

Strut top mounts or sway links ?

That's dumb, all cars should have safety as standard esp blind spot monitoring. Heads up could also be considered a safety feature really, the ventilated seats with memory are a luxury. I'll tell you what - I recently drove a Kia Cerato & all I can say is that I was pleasantly surprised just how good a car it is. Suspension is extremely well sorted - first class really, brakes were great, engine ability/smoothness & economy were good. Interior was average as it was a base model but hey - it's cheap plus that 7 year warranty. Well worth a look. Toyota is no longer alone, this from a life long Toyota fan & owner.

SX V6 would be the most entertaining & smoothest but also easiest to lose your license on 😕 What extra safety features does the SL have over the SX? Would have thought exactly the same.

@thisguy how do you find it ? Any concerns ? Where could Toyota improve it ? Cheers
