Ok, i have a friend who has just bought a 95% complete westfield with a C20XE engine in it. He needs to know (For the SVA test) what the engine number is, and if you can identify the year of manufacture from it. The following numbers have been found:
R90 400 015 - near the dip stick.
20 XE 14 129679 - on the side wall of the engine, exhaust side, right next to the bell housing of the gearbox.
Also found: 46935 and 47015 stamped into the end of the head.
