upper timing cover

[James1975 2]

what size are the bolts that are on the bottom half of the upper timing cover that sits next to the engine mount?

 

Think i'm missing 2 of them

Assuming that you're talking about the top most part of the timing cover covering the cam pulley on an XU 8v engine, then it's a M8 x 1.25 and M6 x 1.0, both 20mm long according to Servicebox (70 and 73 on the diagram)
