I checked my valve clearances today and found that many where out of spec and was wondering if anyone of you knows an online shop to get them as cheap as possible?

Cheers, Mark

Are you aware that IF you measure ALL the clearances and then measure the actual shims they can be rearranged to restore correct clearance on many valves and ONLY the ones you can't correct have to be purchased or procured?

An engine rebuilder may also have used shims which will be suitable ie from blown or totalled, cooked .engines. that source may be cost effective but always check the shim's upper surface for condition.

You still have to know what thickness came out of that spot and can therefore select a shim which restores the clearance for that valve. A micrometer is a handy item there.

Check what's available at Precision Shims Australia. They have shims from 7.5mm to 40mm diam, can't remember what the 1HZ diameter is. Price for some I got a while back (25mm) was OK.

Terrain Tamer (Don Kyatts) have the shims much cheaper than Toyota. From memory they were just over $10 each.

Buy your shims from a reputable outlet as suggested above. Elcheapos may be made from poor material and will change with the hammering they get during use.

When I checked those in my Troopy just after buying it some were noticeably distorted whilst some were ok. I took this to be the difference between original and cheapies. I used Don Kyatt too and they have stayed the distance.

Hi all,
is it hard to check these shims for clearences as I'm assuming you remove the valve cover and they are there to see but from this post it sounds like a relatively easy job, so is this the case as I've been told to "DO" the shims on a 105 Diesel L/C is anywhere from $350 -$500 ?

Hey Johny boy,

I would definitely say, that you can easily check them for clearance yourself if you are halfway mechanically minded.
You only need a feeler gauge and the tools to remove the rocker cover.
However, you would also need a big socket to turn the engine over on the crankshaft. For me (80 series HZJ80) it was 32mm.
Some even just turn the engine on the idler pulleys of the fan or a/c belts...

If you need more info, I could send a scan of my service manual. However, it's still for the 80 series.

Changing shims is a bit trickier, but doable with a self made tool (you only have to cut a piece of metal) and a few screwdrivers. No need to buy that Toyota SST.

Thanks for the infos guys.
I ended up buying five (could change the other ones over) shims at Precision Shims Australia.
Super fast 1 day delivery and $9,90 each.
Definitely no reason to complain^^

Will see in a few thousand k's how the shims perform, but they looked pretty high quality to me.

Cheers, Mark
