Thanks John...your invoice arrived,along with Paypal confirmation.

Inpuressa,
Sounds like there isn't much of a seal there. Generaly you will see blowby signs on both piston and sleeve liner surfaces at exhaust side. Take an eye loope or mag glass and note the residue above window. After removing the pisto + sleeve set and looking the surfaces over for yourself, ship it. Be sure you look the bearings crank pin + conrod over real good.any questions call text or email me.
Kind regards,
Ray
