yeah i hear the tapping aswell although mine is on idle. i know the 2zz are known to make loud tapping noises but my tapping on idle just seems to be really loud. i can hear it clearly from like 10 metres away. am i getting worked up over nothing? or shouldnt i be worried.

i think i have the same problem as you do. The noise is coming from the timing belt tensioner. I already booked in to get it done under warranty next week. Will let you know whether this will fix my problem.

I would start with the basics first.

I had once over-oiled my airfilter which in turn soiled my MAF and caused my engine to ping/knock at about 3000rpm when accelerating under load such as going up a hill or full of passengers.

I cleaned the filter again, cleaned the MAF with spray on electrical contact cleaner (JAYCAR green can) and it's all gone.

So give your MAF a clean, and fill up with 98 at a different Petrol station than your usual and see if this makes the problem go away. Hopefully it's as simple as this.

just clean the maf... checkd the oil.. and then... there was very little oil in the system... could be the problem atm..

was going to suggest oil but thought you might have already checked that weekly with the charger.

Are you running a catch can to see how much is being blown into the intake?

If it's burning oil I'd run the 15W

Lucky 1ZZ long motors are cheap ;)

went to the mechanic... emptied out the oil.. 1l as left... oil level really ultra low. topped up with elf oil... added the nulon lifter thingy... could be a lifter stuck... noise still there.. if this continues.. stage 2 will start in 5000 ks....

Mate steer clear of that Nulon stuff. It will cause more drama's than it will fix. It's full of suspended solids like moly's teflon's and graphites etc that like to clog up oil pick ups and the like. They do not do what they claim.

As for the ticking noise my guess could be broken piston rings. You did say it is low on oil so maybe that is the reason why.

if the noise is getting worse I'd be hesitant to drive the car. Will most likely do a lot more damage. Wouldn't suprise me if the engine lets go completely before 5000km is completed.

Take it to a mechanic that knows what they're doing and they should be able to pinpoint the source.

hope this will help. I just got my car back this afternoon from toyota. They replaced a new timing belt tensioner and the tapping noise that i had before all gone. Noise does travel from one side to another especially there are lots of metal parts in the surrounding area

The sounds get really loud when the engine is getting hot. But with the new part, all gone. I am happy with that. They also told me that they re-adjusted some of the metal air-cond pipes.
