Feature of 4M40)))QD32 does not have a chain or belt, just gears + no dampers, everything is as simple as possible)Your photos are like a scientific dissertation))))The most reliable way is to remove the valve covers and look at the valve lifter cams))You are now more than half way down the Rabbit Hole.
I could not use the marks from the bottom pulley wheel against the marks on the casing to determine number 1 at TDC as the pulley wheel is known to slip on the harmonic deadener, so the marks were unreliable.
I had to go down the long route to time it up changing the chain whilst i was there.

With the 4M40 pump being mechanical any deviation from the bible means - do it again.
Thank you). I've already thought about this. I found a used part at a reasonable price.. And what to plug it in.. Drilling something means I need to dismantle it so that the chips don’t get into the oil. In any case, dismantle.. I read this is the oil heat exchanger, that is, it is necessary to drain the antifreeze from the system..Remember the thread for the oil pressure sensor is UNF fine.
MAYBE consider taping and plugging original hole with standard thread and bolt, then take your oil pressure reading from something like this, also easy option to add oil pressure gauge for safety from one of many outlets.

About the diesel engine QD32. This is an incredibly reliable engine and with low mileage over the course of a year, I can confidently say that it will last a very long time... just like its brothers TD42, TD27, SD33...Just going through your thread and had an idea of buying diesel e50, I could do it and would be happy to work on that big diesel, but then checked the prices and hot import from Japan is £10k/2001. Ooofffft! I guess I’ll be looking at different diesels then
Thanks for sharing your journey with us.
The QD32 has a very simple EGR system. There is a valve for supplying exhaust gases to the intake manifold, and a valve that shuts off the air supply proportionally.BUT I deleted this case) No electronics, everything is controlled by vacuum.Curious about the engine, is there an EGR valve if so, do you have it blanked?
Fuel quality)That’s why I like older diesels.
newer ones/ after 2010 are all have sensors around EGR and coolant/oil lines connected.
Absolute pigs to work on.
Below is a 2015 Diesel with 60k miles on the clock.
Edit: and that’s only intake elbow past the ‘throttle’, I can only imagine how the intake and valves look like. That’s why I’m getting water/methanol to clean this sh|t.
True, I’m old enough to remember how proper diesel smelled like. What we have now is mixes, refined and full of all sorts of detergents, that might clean your fuel rail but shouldn’t be burned, also low sulphur so there’s no good lubrication on piston/rings/cylinder wall.
DPF itself is good enough and with adblue/DEF it’s cleaner than most petrol engines.
EGR as mentioned (cooling/ efficiency(lower burned volume) can be replaced with water methanol injection , which will have same effect (less NOx) .
I would never touch the DPF as it does the job of keeping my backside clean and smelling good
Do you add two stroke oil to your diesel? I would suggest to do it, your piston rings will thank you. Would not do it on modern diesels but older ones have no issue with it.
