Common places to leak oil
I am looking at a FD this weekend. It has an oil leak. Where are common spots to check and or be very wary of?
Car has low miles at 35k. seems odd to be leaking oil.

Most common is the oil pan. The factory gasket is useless and the pan should be re sealed with a pan brace using only silicone gasket maker. Next place I would check would be the oil filter pedestal o rings. Best thing to do is wipe everything down and look for fresh oil

Sometimes the clutch line can leak and be viewed as an oil leak. the clutch line is right on the firewall, sometimes it leaks and goes down by the engine mount/oil pan area. Mine was doing this and I thought it was the oil pan.

There will probably be leaks in spots you cannot see without some disassembly.
Often the oil pan is blamed, because the oil runs down the block on to the pan.
I've fixed quite a few oil leaks, at least 10 over time, and it has never been the oil pan.
OMP, Oil injectors, oil level sensor, oil lines, etc.

External leaks are ok (other than making a mess) if they don't leak so much that your engine is starved of oil. It's the internal leaks that would be of concern (engine and/or turbos). Here's more on the subject....

I think it would be faster to list where it DOESN'T leak oil .
Hands down the most common is a seeping oil pan. They're nearly impossible to seal up right even if you do everything right. New they had oil pan leaks too.

I just found an oil leak on mine. I steam cleaned the hell out of the engine and found the oil filter pedestal leaking.
Anyone know the Mazda part number for the o ring, gonna try and get one local.

I've been lucky so far. First leak was from the rear turbo--about a drop a day for the past 15+ years and not worth the trouble to fix it. Next was the oil pan. That was about 14 years ago -- a messy leak that had to be fixed promptly. Finally, this spring the oil filter pedestal o rings gave up. Also messy, so that got fixed too.

My oil laek fix!
I used Permatex Spray Sealant Leak Repair Item#82099 just to see if it would work temporally but its been 3 years and still does not leak.
After I found the leak was from the front cover and the specific area of the front cover I cleaned it up real good with degreaser and then did final clean with alcohol, put about five coats of the spray sealant on, so far so far so good . No more oil running down oil pan, trans and frame etc.!
