1HZ Tappet Adjustment

Anyone happen to know the inlet / exhaust valve clearances, cold for the 1HZ Cruiser motor in inches and milimeters

Two large flat tip screwdrivers (or similar) to push down the bucket while the wife uses a magnet to pick up the shim. Can be done by yourself like this but difficult without 3 hands.

Just had my Troopy Valves reset plus gasket $429.00 No shims needed , Prosser Toyota at Gosnells WA

Yeh Thanks Doug, Toyo Mandurah wont $20 a shim, Rockingham $20 a shim, Mellivle $16 a shim, would your no shims needed mean $429 to remove rocker cover and check clearances only - no adjustment necessary ?

Yes that is correct ,

Some workshops do not replace the shims. They machine them down to obtain the correct clearance.

Agree. Don't want it to sheet itself west of the ponderosa somwhere.

Starting to get the same sort of feelings Reggy, could be the way to go ?

yes it can be done with to screw drivers shims are about twenty dollars each. easy to check hard to change.

We did the same in our local 4wd club, cost $20 each for the tool, then it got passed around, any spare shims went in the box, very rare that anyone had to buy shims after the first go round as there were spares in the box.
Interestingly most were done within 30 -40k of new and all were found to have a lot especially exhaust valves way out, usually tight. Setting them correctly resulted in much smoother running engines and better response from throttle inputs.
We also found that once they were done initially they rarely needed redoing until very high k's. You can check them every 100k but they usuallyonly need redoing around the 150 - 200k mark.
Regular 5k oil changes and good quality oil actually made a difference to shim wear and having to reset them when compared between the engines. Those that only did 10k oil changes and weren't fussy on oil (used anything!) found that they needed doing at about 60 -70k intervals.
We also did a comparison on air cleaner elements, some used oiled foam and others used washable Tojo ones, by 100k the foam users burned more oil on long runs, interesting!

Thats pretty well exactly what my mechanic told me. They tighten up from new and dont need doing again for 100000 or more.

He also charged me a hellava lot less than some of the above figures

Thats probably why I got charged a $100 instead of $400+

Ross sounds like you have an honest mechanic too. Would have been very easy for him to charge the $400 odd and you'd be none the wiser that it never required any adjusting.
