It's a 17H block, with the plastic tensioner, so I think it's definitely a 2495cc.
The filter might have been changed over from a series, as it was in a series motor before I bought it.
Here's another question. I'm fitting a series oil cooler to this, because I have one and it's a lightweight, but, is the TDI 200 oil cooler filter housing better than the series sandwich block? On account of it having a thermostat?
I'll plumb the return direct into the sump.
