I am having this done today at Toyota and it costs 500$..o7 hatch
in case you need it done... after 07 probably wont have to. mine went at 150K.now has 200K.

severous01 · 12-17-2010, 08:11 PM

ok.....thanks for the info i suppose.

yaris9876 · 12-17-2010, 08:52 PM

the mechanic said it was a nightmare repair requiring 2 techs to finish it.
it took 5 hrs instead of 2. no shit. they finished it 5 minutes before they closed.
When some of you 07 owners get to 150K, you are going to be doing this..
the VVTI was a stupid design idea for a basic no frills car like the older Yaris.

lol stupid design idea? You don't like the best of both worlds...decent power and excellent fuel economy from a 1.5L? If I remember right the job calls for 4-5 hours too.

Why do you think all 2007 owners will need this? Please explain.
Also, "older" Yaris??

They were doing it wrong - or they did not have the right tool for the job.

When we needed the unit replaced on the HP car, and did not have the Toyota SST for the job, we took it to the TMS garage. It took longer for the tech to pull the valve cover than to change the VVTi unit.

Had a 2001 civic.loved it, but would you rather replace a timing belt, water pump and belts for 600.00 every 75,000 miles?

johnny_vitz · 12-20-2010, 12:23 PM

I hear you on that one ^^^ I just had to do my mom's accord (3.0L), even at cost it was $600 and change (discounted labour). Did the wp and the idler/tensioner pulleys while I was in there.

...On my echo (older yaris...?) it calls for 4.2 hrs to change one cam gear. 5 hours isn't that bad considering. The timing cover/chain has to come off.

why? · 12-20-2010, 10:10 PM

um 150k? There's at least 1 member with 400k miles who only had to do oil changes to get there, none of the engine repairs.

How much did you rev the hell out of the car?

yaris9876 · 12-28-2010, 08:09 PM

at least some of the 07s will have the cam gear go bad...the later ones have a different design. There is a service bulletin out on it and that shows a pattern of failure in higher mileage 07 Yaris. Mine is running perfect now and I put in some Bosch Irids too. Its like having a new Yaris again. I hope to get another 100K
and that will make 300K which is phenom for a 11,000$ rig. Mobile 1 and synth gear oil do it.

ibanezjeepguy · 12-28-2010, 10:23 PM

sometimes dealers will work less experienced techs because they dont want to pay their top dollar guys to do a job that should only be done by such a tech in the first place.
your car got to be someones practice unit.
I dont see why a gear should need replacing unless the system was abused or something with the oiling system failed.
VVTI is a great design feature, helps overcome the feature holding back many engines and that is..... horrible power band and fixed valve timing!!!!

ilikerice · 12-29-2010, 05:39 PM

actually i know what he is talking about the TSB. that year they made a design change in the vvti cam gears. i know for a fact the IS 250 and maybe the 350 had an issue with those. customer complains of a loud ticking noise on a cold start and goes away after a couple seconds. something in the cam gear cracks and calls for a new cam gear part number to replace it. there was a VIN number range that it falls under.

but yes, i did this to an IS 250 that i "practiced" on i guess u could say. with those engines, if the chain slips off the crank and screws up your timing, u gotta drop the engine to take the both the oil pan and sub-oil pan off and then u can take the timing chain cover off.. god that was a nightmare the first time i did it.. lesson learned and now im a pro at it.. hahaha

ibanezjeepguy · 12-29-2010, 07:01 PM

ouch that really sucks!
these are the reasons why I wait several years down the road if at all to get a particular new model vehicle

ilikerice · 12-30-2010, 12:31 AM

^^i +1 that^^

yaris9876 · 12-30-2010, 08:14 PM

Rice you sound like a Dealer Tech..yes? Do you put a newly designed replacement part in when you do them?? I mean the new gear is better than the original ,yes..??
My timing was way off too but I didnt hear that they had to drop the motor...
and my original tech was a rookie... the Master had to fix his work... he got in trouble wih his boss..

That wouldn't have helped in this case. They've been making the 1NZ-FE engine and using it in a variety of cars for over ten years.

ilikerice · 12-30-2010, 09:11 PM

@9876,
yes, when we have a TSB (technical service bulletin) on our tech stream its only a quick reference to certain customer comlaints. its not necessary a "recall" because its not life threating, but a mechanic malfuction in the vehicle that happens and can usually only do anything about it if the customer complains about it.

toyota keeps track of all the custom complaints that are recorded and when they have an issue that happens abnormally too often they investigate and usually fix the problem with a new product. before the TSB when people comlain about this they usually call the tech hotline and they will tell u what other techs around the world did to fix the problem. before it was just replacing it with the same part number. then the TSB comes out with a NEW part number. its basicly the same but redisigned.

so yes, you are getting a new part reguardless, but if there is a TSB on that particular issue like the VVTI cam gear, u will get the newest and latest disgned part.

as far as dropping the motor, i worked for Lexus, and the IS250 requires u to drop the engine if you screw up the timing cuz the timing cover is also part of the sub-oilpan which you cannot get off without dropping the motor out from the bottom.
as for the yaris, i have yet needed to pull the covers off or even see how its engineered but im sure you dont have to drop the motor to get the timing chain off.
i think CTscott is a toyota dealership mech and he would be able to help u ALOT more. that guy is a master of his craft for sure
