Discovery 200TDI Pistons

so my block is ready to start measuring pistons and rings



Upon stripping I noticed I have two piston types;
3 x TX ERR1387:




and 1 x TY ERR1388



limited or no info is available that I can find on the two types, I can't even find ERR1388 mentioned anywhere.

Any piston experts able to shed some light for me please?

said Pistons:

Just honed or bored?
Island 4x4 have different makes and sizes listed, discovery section engine parts
ERR1390, ERR1390R, ERR1390G
Rumour has it that a certain very well known engine recon company is using britpart pistons with no issues.

Thanks Lynall,
I just glaze busted them at home myself,
I haven't started measuring yet but would prefer not to buy Pistons if I don't have too

can you find any reference to the numbers I pictured at all?

muchos for the reply

original piston did come in 2 grades (size) numbers are irrelevant now as new numbers were used for replacement pistons, though you should have only one grade per block

Looks a tidy job hence why I asked.
Sorry no knowledge of the numbers but like most things Im sure they have been superceded many times.
I quoted Island 4x4 as use them myself and decent gear, if something may cause trouble they tell me and I get the better one, sales ploy maybe? but so far I like them.

Pic hopefully might explain what James was saying above.

I'll get measuring then,
got a single standard ring coming so I can put it in bore top middle and bottom to measure gaps, hopefully all standard if not I'll be looking at a poss rebore,

the bores were quite glazed, hence my reason for honing:



The Pistons that came out had no friction material/skirt like a 300 piston-that normal? never opened a 200tdi before.

just sold my series 3 that I was rebuilding this engine for so only rebuilding to sell now.
