You say seats are bad. Normally the valves burn out before the seats. Do you have photos of seats and valves? I assume exhaust valves were worst, right? Have you identified the cause for bad seats? This should not happen with hydraulic tappets.

I think I can now explain your intermittent start problem. The engine had low compression on number one cylinder. I think engine had difficulty synchronizing. These engine do not have any cam shaft position sensor. Cam shaft position is therefore sensed by the increase in resistance at compression stroke. This method only works on a single and three cylinder engine. Having low compression on number one cylinder will make it harder for ECU to feel its compression stroke and engine may fail to synchronize.
So what can be done?
1) Restore compression on number one cylinder - possible but takes time, effort and parts. Re-bore and new pistons will be required if one cylinder is worn.
2) Fool ECU to synchronize on a good cylinder. Will require lengthening of the leads to injectors. Will it work? I don't know but there sure is a way to find out - try!

TK. I have responded to your post on Vainiacs.
Good piece of detective work!

This has to come with a warning.
Under no circumstance put any part of your body near the injector tip (or vice versa). At the elevated pressures involved you will experience what is termed ''hydraulic injection'' where the Diesel will be blasted straight through your skin into your flesh. The resulting poisoning requires amputation to remedy.
Take great care not to allow this to happen.

And the nozzles are so fine you can block them just by touching the ends, even if they're not in use... Take care when refitting.

But if it has to have 4 wheels, make it the best in the world at what it does.
Think you can drive? Prove it. Then learn to tell the difference between handling and grip.

Perhaps easier said than done. TDC sensor probably will have to be moved 120 degrees for above to work.

problem solved with general rebuild engine. compression is low.
BUT; NOW I HAVE NEW PROBLEM. WHEN I TURN KEY FOR STARTING, I CAN ONLY HEAR CLICK. After 5-7 attempt engine start ok. Sometimes engine turn over very slowly but rare and wont start. No any signal light warning.

Sounds like you need to clean the starter motor and the connections to it.
The connections are not the best available!
