Spent 2 hours pulling the Miata engine apart to try and track down an oil leak with the help of an oil additive and some UV light. 90% sure it’s the front crankshaft seal.
Gotta order some parts and will probably take me a day to finish the job. I’ll need to pull the timing belt and re-time the engine, so that will be most of the work. Really hoping I won’t have to drain the coolant, but we’ll see.
