toyota 1HZ engine noise

Jack.
Welcome to the club!! I have a 92 troopie fitted with the 1HZ motor. I bought the rig in 1993 with 42,000 km on the clock, that still meant that I had 12 month warranty on the body and 2 years on the drive train.
Now the ticking, yes it was there. Toyota replaced my pressure plate, spigot bearing and bush, but the noise still persisted. They could not solve it. I was told not to worry as I still had plenty of warranty left. As I had 42,000 km already on the clock and the motor was still working OK then why worry? If I still had concerns then I should wait until I was close to the expiration of the warranty and represent the Troopie and they would look at it again.......So be it and so I did.......YES, was the answer, this time, We now know what the problem is. Some on the crankshafts when they were ground had an undersized journal at the rear main bearing which they would now fix. I asked if they intended to put an oversized bearing to off set this, NO, that was not the way of Toyota, a new crankshaft it had to be.....:) said I!
I picked it up a couple of days later, and low and be hold......THE CLICKING WAS STILL THERE!. Now I was told, don't worry about it, you now have done 80.000 KM and it was still working and to boot you have a new crankshaft, why worry, the noise is only engine harmonics and is not a problem. My fears have been recorded with Toyota Australia for future reference, if something did happen then they would re-visit my file and decide as to what if any action they would take..........I have now done 130,000 km with that motor and have also fitted an after-market Inter Turbo and that has traveled 30,000 KM (and some times very hard kilometer as I am in a 4WD club) and the motor is still working as good as the day I picked it up,......and YES, the clicking is still there!......I hope this has been enlightening for you as it was and still is for me.
Regards

My late 92 with the 1HZ has had a ticking noise in it, on and off, since almost new. You guessed it, the dealer could not find it or was very interested in doing anything about it. It was very intermettent at the time and only occured when you have the foot off of the acceleratorat around 40 kph. Now wth 116k on the clock it seems to be there most of the time when you de accelerate anywhere from 80kph and 20kph. The noise seems to come from the area of the clutch? I thought it may be a loose baffle in one of the mufflers.

I would not go back to the Toyota dealer because I don't wish to take out a loan to pay for the work and previous experiences of grease on floor mats and the cap being left off of the brake resivior on two ocassions has soured my relationship with them.. I am convinced dealers just treat your vehicle as a source of income and their business as a sausage machine. Push it in one end and hope it comes out the other end as expectedwithout any care of what happens in the middle. Would be interested to know if this clicking with the foot off is tha same as others are experiencing. The vehicle is performing well.

Yes MR TOYOTA service doesn't achieve much credibility.my 97gxl 80 had numerous visits during warranty, it av 3 visits per repair. I also had a very rare intermitint ticking at 105 k at idle & thought "what now"
10 000k later head gasket leaking This time I fix, upon dismantling the rhs head studs were ALOT easier to undo than the lhs as was the cam drive gear upon viewing gasket blow by was everdent at no5 but was also there with 2,3 & 4. and all on the rhs of gasket. On checking shim clearences and rotating the cam i noticed wear on the taper from the cam drive, after completeing job, noise gone and oil consumtion gone.
For the oil usage was from the flaps on breather baffle plate being at 48 degrees where it should've been 30. Mr YOYOTA said it was running in.
(1.5 lt / 5000ks from new)???? why we don't have faith.
whether this may help ? just a thought.

yes my 2001 78 series started making the same noise at around 20000 kms took into dealer and they had another vehicle with the same problem which the experts from japan had just taken apart and replaced the crankshaft the told me it was number 5 main which is where the thrusts are located my dealer offered to replace crankshaft but they couldnt garantee that the noise wouldnt come back so i didnt bother i have since done 50000 kms with no problem it is a lot more common than people realise that is untill you buy one that starts ticking
