So Some of you know the cherry dt's engine locked up shortly after the owner rebuilt it. Well ill let the pictures do the talking. Please note this car never go driven on the road after the rebuild!
Lets see who lists all the problems

I do have to say he did buy all the rebuild kit with a nice metal head gasket! But are these decomp pistons? Im lead to believe so?
Taking the bottom end apart tomorrow to see if they are hdi rods and why she sized solid.

The indentations in the pistons do look a bit shallow so possibly. You say the engine has locked up? Whys everything covered in oil?

Aren't decomp pistons just normal ones with the top shaved off a bit? If so, they do look like that lol!
As for seizing, gotta be lack of oil surely? Lack of lubricant and overheating of something, big end shells or maybe pistons I guess....maybe they forgot to refit the oil squirters?

Actually looking again, cylinder one (cambelt end) looks higher than cylinder 4. And also the bores are like brown. And the valves and the head look like they're caked in oil :/

Well looking at it in person theres oil dripping down the side of the bottom end. water inside the chambers. No way the metal gasket was doing its job! The oil on the pistons and valves I don't no??? The head wasn't cleaned nor the bottom end, So he rebuilt it on a dirty block !

That's a pretty major fail tbh...how long would it take to clean it up ffs! 
And now you mention it, the headgasket does have carbon/soot between the cylinders so looks like it was blowing between them, and obviously where the water got in too. So I'm guessing its bent a rod if there was water in there?
Also, check that the block/head aren't warped at all if you're rebuilding it, as I wouldn't be surprised tbh. If he didn't clean the block I guess he didn't skim the head either?

So it all looks normal when I took the sump off.
[attachment=14093]
[attachment=14092]
Untill I took the shells out, here's what happened.
[attachment=14094]
Three shells looked like this, by the looks of it the chap was working in a very dirty space as the shells was covered in dirt and grit. coursing this damage.
but then I got to the 4th shell. (Fly wheel side) To be greated with a loose bolt on the shell casing :O
Well ill let the pictures do the talking.

What a Tool!!!
A piss poor head change and a loose bolts! Even when I was taking the sump off there was a bolt missing and 3 bolts where loose! Just say away from engines pal.

This is the reason I hate buying 2nd hand cars without history, people like that have been trying to fix them! Did you buy the whole car or just the engine? If its the car I'd be checking everything else as well lol.
