Edit: The ZZ engines are shimless, they have differing thickness buckets instead. Think the buckets are alloy too so they're much lighter than steel buckets + shims.
Yeah, high revs can spit them out of the over-bucket system. Happens in early 3SGTEs if you raise the rev limit, they changed to under-bucket halfway through.

I wasted a whole day today trying to do the timing belt. I think either the marks are printed wrong on the belt (which are only for reference anyway), the belt is for a different UZ engine, or the workshop manual is wrong. It tells you to put the crank to about 30 degrees ATDC then install the belt so the cams all line up with their timing marks, then put it all together and spin the crank 720, put it to TDC and see if the cams line up?! Of course they won't, they were set 30 degrees off to start with... stupid ******* toyota manual.

Anyway, the cams are back in, the heads are all back together with new seals all over the place and the belt is half on. Just needs a bit more messing around. I'm going to ignore the manual, and ignore the guide marks on the belt, and just set the crank to TDC and the cams to where they are meant to be, like you would on any other engine.
Good enough :p

I've been using the painted T but I suspect that actually it's the large notch to the left of it, which means the timing was bang on all the times I did it before...
I also dropped the crank pulley and knocked a f**king great chunk out of it so I'll be needing a new one of those now.

My phone conked out so I don't have a photo of it all back together but I got the belt end fully assembled and got the water pipes on too, new spark plugs in etc. Here's just the belt:

I'm confused about timing now. Which do you suppose are the timing marks on the rear belt cover, the large notch or the painted 'T'?

Step 18, however the diagram has a mistake in it - there is no way after a 720 degree turn of the crank that the L-CAM / R-CAM labels on the belt would be back on the cams already. But I can't work out which mark it's meant to be lining up with. The more I look at it, the more I think it's the larger indent which has to match the notch in the cam gear, which is not what I did...
You can see the workshop manual for setting the timing belt, it's at

Uhuh, that's what I think now looking at it in a fresh light. The thing that put me off is that the T and the marks on the cam gears are painted yellow, like they've been matched up that way before.
So I get to refit the timing belt for the 8th time this weekend lol. Might have a go at lunchtime.
