Corner of oil pan leaking slightly
Gents,
Happy New Year to All, and best wishes for a safe and prosperous 2020.
The driver's side front corner of the oil pan is weeping a bit of oil. I'm positive it's not the front main seal--the oil is localized. Should I just tighten the bolts in that corner, or should I remove, clean, and put new sealant on before tightening?
Thanks,

You don’t need to put sealant on the bolts, or at least you shouldn’t have to. You can just tighten the bolts, but there isn’t really a gasket to squish, just improperly installed RTV, which will still be improperly installed. It’s worth a shot but most likely you’ll want to pull the motor and reseal the pan.

This engine is a low mileage part-out and has about 80k on it now. I plan to run it into the ground. I suspect with proper care I can get another season out of her. I have a rebuilt engine waiting in the garage, forged pistons and rods, ARP, Volvo valve springs, etc., but I have decided not to remove the current engine as long as it's still making good power.
The seeping isn't bad. Although it is visibly noticeable, she doesn't eat a lot of oil.

I had the same problem and found the above solution in an MT build thread about ~2011 or 2012...

One question... Did this engine previously have AC? If so, when the cast AC compressor bracket was removed from the block there were 5 bolts, 4 from the side of the block and 1 that passed through the AC bracket, the Oil Pump then into the front of the block casting (this bolt runs parallel to the crank). When the AC compressor bracket is removed, you need to insert a new (shorter) bolt to fasten the Oil Pump onto the front of the block. If you do not, then oil will seep out between the oil pump housing and the front of the block.

If you search miata.net you can find the exact size you need bolt you need. I have found them at Ace hardware several times without issue. It had just been a few years since I last replaced mine, so I am not sure on the size.

Thanks to 99Racer for this insight.
I just pulled the AC on mine, and did not think about that bolt needing to go back in. I might have caught it when I put the oil pan back on, but maybe not.
And thanks for the thread we were linked to, it mentioned one of the bolts pulled was already the right length, and indeed it was.
