Comes from brown cows, and not Toyotas.
This engine has been sat for several years, it looks like the oil is a fragrant mix of fuel, old oil and something that might be coolant or condensation.
Will have a deeper look inside once I’ve got some more parts storage trays to keep track of all the components. The valve train all looks nice and clean, but who knows what else lurks inside...
Oh and the engine crane decided it wasn’t up to the job, so that’s an added bonus.
