OK, so they pulled the engine to inspect the cams, everything is in good shape.
For whatever reason it wasn't apparent until now that the belt was indeed out of time. I checked it myself the first time, it looked fine. The shop checked it, all 3 marks it looked fine I guess. It wasn't off by much, and to be honest my timing marks are a bit ambiguous which could have been the problem.
So that's that.
One thing we talked about was why this happened and how to prevent it in the future. Now this is something I've never heard of but apparently some Subarus with factory-equipped manual transmissions have something called a timing belt guide which is designed to prevent the belt from jumping, seemingly because this is a prevalent issue in manual cars.
He seems to think that if only our oil pump required a single cam sensor instead of two that we could pop in an oil pump from a different car which has the guide mounting holes and this would potentially solve the problem of jumping timing belts, sparing people like me all sorts of grief.
Any ideas on that front?
