  1. Ever since I had my gearbox done (bearings and synchros), ive noticed a slight vibration, that gets more noticeable with higher revs.

    At around 2-3k revs, its barely there.

    But once you start revving the engine a bit harder (4k and above), and change gear, the pedals (even the brake when down shifting) and gear knob tend to vibrate with the engine...

    Anyone else find this to occur?

  2. i only have a 1zz and i constantly shift at or above 4.5k, the car was built for revs, ive just had the 40k service and was told that it was the cleanest and most well maintained, drivetrain, rolla they had seen for a while.

    They asked what i was doing to keep it that smooth

    You're exactly right

    The engines (1zz and 2zz) were built for high revving

  3. I know its late notice, but is anybody interested in coming to the VDRC Drag day tomorrow at Heathcoat?

    Gates open at 8am, Qualifying is at 11am and racing starts at 3pm.

    Entry is $20 for adults, and i think $35 for families...

    It would be great to see heaps of people from the TOCA there, to show all those V8 heads what a 1.8L can do!

    Anyway. Hope to see you all there

  4. I've found from past experiences that the whining noise is the Syncro's.

    However the tapping or rattling you've described was apparent in my car too. And it would stop when ever the clutch was fully disengaged (pedal down). It also disappears once the car is going faster than walking pace.

    Brought this to the attention of the Toyota crew who put it down to the gear box being a little more heavy duty and 'helical" than the stock 5-Speed. I don't totally buy this explanation, but what you going to make them do?

    Toyota have already said they are going to replace all the parts

    And its not going to cost me either. Seeing as the car is still under warranty (for another 5,000k's)

    that's your clutch fork/throwout bearing if the noise goes away with the pedal down.

    ps, helical cut gears are quiet. Straight cut gears like reverse are noisy.

    The gears in the 6-speed are no stronger than those in the stock 5-speed.

    Yeah, the noise goes after the clutch has been depressed.

    True about the 6-speed and 5-speed

    Ive heard they are both pretty strong

    Not in this case though ey?

    Do you know what usually causes this problem at such an early stage?

  5. Im not sure if many of you will remember my earlier post about having a 'tapping' noise in the engine.

    After waiting a while, and taking the car to Toyota twice, the problem has now been solved.

    THE GEARBOX!

    Yep, its either gonna be the bearings that get replaced, or the sychro's. (my guess, the latter. between 1st and 2nd)

    The rattle of damaged/worn bearings was echoing up through the engine bay.

    And i didnt even say anything about the gearbox

    Toyota found the problem themselves!

    Not bad, i must say

    But now they are going to have to keep my car for at least a week :(

    Or did they break it whilst on a test drive??? Not the first time I have heard of this happening.......

    Nah dude. I had noticed a weird noise every time i put the car into 1st.

    And on the downshift from 4th-3rd and 3rd-2nd, the gearbox produced a loud whinning noise

    But never reported it to Toyota

    I was more concerned about the tapping noise coming from the engine

  7. Northy, going through the service manual (that you uploaded)

    Where can i find a parts catelouge?

    If there is one, does it have a diagram of the part that i want?

    (in this case, chain tensioner)

    (ps. im still not 100% percent convinced that it is the timing chain tensioner. why would that make a tapping noise?)

  8. The chain tensioner is in the case that i have taken off the engine, but it puts pressure on the little black plate where the arrow in the pic is.

    Dude thanks heaps for the pic. Great help

    Can i just ask though, does the tensioner mount to the left of that little black plate? Or is it mounted 'on top' of it?

  9. Ive got the car booked in for tomorrow.

    I'll be sure to let you all know how it goes

    Thanks for all the help once again!

    (ps. if anybody has a technical diagram so i can see exactly where the chain tensioner is, that would be a great help!)

    It's in the downloadable service manual.

    Where is that available from?

    The AUS Toyota website? Or this forum??
