vvtl-i problems

[bagadonutz]

my mass air flow was bad so i replaced it (the dealer wanted 331 dollars to replace it, right! i did it for a hundred) my celica was like the day i bought it. now three weeks later i lost my vvtl boost. at 6000 i feel a sort of engagement but nothing happens it just sound like the engines straining, no growl, no power. could it be the oil sensor that engages the cam? i don't think its the ecu because it seems to do somthing at 6000 rpm.anyone had this problem? thanks in advance

I think there is a Toyota Service Bulletin for the 2ZZ-GE engine; looks like there is a manufacture problem with the bolts that engage the VVTL-i system, they get worn down so much the system fails to engage the "higher profile cam" thus you are not getting the kick in the pants you used to get when the car was new.

I cant remember where I saw this info, it was probably at the Team Celica forum site (www.tcforum.com)

yep, they did a recall on it.....here in canada, they found out about the problem after the engine hitting 100,000km.....
hopefully your's is still under waranty

Its the infamous lift bolt problem. Basically its a bolt that wears out and doesn't allow the motor to hit lift. The shitty running condition is because the ecu thinks the car is in lift and throws in extra fuel and timing.

thanks for the bad news, i guess it time to rip it apart and take a peek, hopefully it just worn and not busted off. how can a car manufacturer make an engine that a bolt breaks in and not stand behind it.

Did you read the threads? Toyota will fix it, call them and take it in for servicing.

i have 62000 hopefully toyota will goodwill the repair. they still will charge me 80 dollars for the diagnostic if toyota doesn't cover the repair, in which case i'll end up doing it myself.
