Valve adjustment

The 1HDE-FTE valve arrangement in the diesel toyota was a real surprise to see once I had spent the best part of an hour just removing all the gear to get to it. Wow!! Now I have some experience from a couple of decades ago with very simple, perhaps traditional set ups, but this level of engineering was a very different kettle of fish. I have finished the job, all back together and running quite nicely. Having done this however I have a few reflections to share:

1. I now understand why my local Yota bloke described this as a "buggar of a job" and tend not to do them if they can avoid it.
2. The Yota service manual suggests a feeler gauage be inserted first to check clearances. THIS IS IMPOSSIBLE given the design of the rocker and the nature of the cap that sits between it and the bridge sitting across the top of the two valves.
3. The Yota service manual is a little confusing and requires a couple of re-reads to make sure you fully understand the sequence of adjustments on each rocker.
4. Whilst I'll do them again at 80K (40K this time) I don't expect there'll be much change in tollerances.
5. I was surprised at the amount of soot that lies coated within the inlet manifold, compliments of the EGR system.
6. This stuff is so over engineered (rollers everywhere) it should be bullet proof. I will not be reserved in applying RPM in future, and
7. finally, as a desk jockey, I have the satisfaction of having done the task and learn't a little bit more about why I should get others to do this work for me!!
