Hi all,
On 17 May I posted a query (33988) about adjusting the valve clearances on my 1HZ engine. I have just finished the job. I had to buy a micrometer and a magnet pickup. I started on Saturday by doing all the measurements and working out what shims I needed. I bought them off the shelf this morning from Toyota ($15 each) and fitted them in. The gregorys workshop manual was pretty good with the procedure. I didn't buy the SST, instead I made up one of my own out of 1" flat steel to hold the bucket down while changing shims. (Nil cost). Five valves needed changing. I bought three new shims and re-used two for other valves. To those who gave useful answers to my original post ( Peter, Topcat, Off Track and Andrew Rodeo) thank you all.
By the way, the 100 series is a big lump of a truck to work on the engine, I am not getting any younger either. I used a wheel step for the side access and a step ladder for the front and my legs are killing me!!!

Did all the effort make a difference?

Good question!

Buying a second hand vehicle, I like to know as much about it as possible. My particular 105 was a police camera car so it has been sitting idling on the roadside for many hours (for the aircond and power), the low kms aren't a true indicator of its engine condition. Now I am confident that it is OK although I can't feel any difference when driving it.

Hi Andrew,
Yes it is quieter, I could hear one ticking before which got me onto the job in the first place. That ticking has gone so I am happy.
