I have been informed that Volvo no longer offers the OS1 piston for the B5254T engine. I learned this .020MM OS piston isn't available after having my block bored, which is a pain in the wallet. This is Volvo part number 272242.
The OS2 .040MM OS pistons can still be ordered, or so I've been told, until I have them in my hands I'm dubious.
If anyone can source a .020MM OS piston for the B5254T engine, I'd love to be proven wrong.
B5254T Rebuilt Warning for pistons.
