Not observed any differences in the blocks myself. Wiki is not always authoritative.
The coated pistons on the later engines do make holing a piston less likely. And injector servicing also reduces the likelihood of that happening.

Ive seen 19j's with every piston cracked and still going strong, I doubt changes in the block would have been obvious, but it was obviously needed to prevent them from cracking and splitting.

So have I, and sometimes with a blown HG as well. :D

Sorry, still not convinced about the blocks, they all look the same to me.

They will do, the changes were probably minimal, might have just been the main bearing seats that were different.
 
Here are some pics

Yep. So minimal they were non existent.:)

Two part numbers are listed, RTC5031 and ERR479 , RTC6795 is superceded from RTC5031, ERR479 is from serial number 19J27515C so my guess is they did something other than change the part number..

Note the breather pipe is much longer than usual
 
Won’t the engine blow up with all the extra Oil in the engine though if I plug the feed and return pipes

What feed and return pipes? The pipes I am talking about are diesel and air pipes, going to the boost unit on the fuel pump.
The oil feed to the turbo is just an oil gallery, the oil will go somewhere else if you block it. A 2.5 NA doesn't even have the drilling for the oil, and they don't blow up.

Yes the oil pipes changed the turbo now won’t bloody start now turns over really slow knew the engine was too good to be true for a 100quid
