Identification of F15 2WD?

[Ganmain Tony]

Started a bit of a brief inspection of the engine. I have the invaluable assistance of one Mr John Mackie.

Started cleaning the engine up.. removed the sump and removed the yoghurt in the bottom. Came up very nicely.

Cleaned the bores and turned the engine over OK so far.

A lot of carbon and gunk in the top of the engine (no suprises). Refitted head gasket and head. Performed compression test (using thumb gauge) weak in centre two plug holes.

Next step - Need to do much better clean to make sure no carbon preventing exhaust valves shutting properly.
