Well of course, a lot of this is due to my wild procrastination. I haven't had the miata on the road yet this year, because I wanted to do the timing belt before I woke 'er up for the year.
I took it in to get that done yesterday (with a 15 month old child, and my lack of know how, I have neither the time nor ability to do it myself). I knew I had a teensy oil leak somewhere on the block (I thought Oleg had that licked when he did the CAS O-Ring and VC gasket), but it turns out it is far worse than imagined. She's leaking pretty badly.
So, it could be one of a few things.
1. VC Gasket is bad: no big deal.
2. CAS O Ring is bad: also no big deal
3. Rear Main Seal: Engine pulled, won't be back by Friday.
4. Oil Pan: Either the subframe in the front needs to be dropped, or the engine needs to be lifted. Either way, won't be back friday.
5. I don't want to think about what five could be.
