The Jet - New beginnings
Posted: 04 Nov 2025, 17:40
The Jet wasn't really on song at Narrandera so some investigation was needed.
So far it looks like minor head gasket failure, and the exhaust valves hitting the pistons. Head gasket issues aren't a surprise here, but the valves hitting pistons is a development. None are bent, and the piston heights are ok, so I need to have a look at the adjustable cam sprocket as I think it may have slipped i.e. cam timing is too far retarded.
