Removed my zspeed undertray today, and there's a leak somewhere but I can't find it , the undertray had an accumulation of oil/dirt. Anyone have any suggestions on what I can to find the source of the problem and how I can fix it ? Thanks.

 

looks pretty substantial.

clean it up as best as you can and then crank it up. see if you can see the fresh oil pouring out.

 

Definitely clean it up as much as possible, then you can get some dry powder spray deodorant and spray it under all that or at least in the area you suspect the leak to be coming from. When it starts to leak it will discolor the deodorant giving you exactly where its coming from.

 

That's an interesting trick - never heard that one before. OP, are you sure it's not just a leaking oil filter? After you get it clean, even if you don't change the engine oil, spin a new one on there are see what happens. I can't really see any oil above the filter area.

 

Clean the engine. Use a UV dye kit. You'll find the leak in a day or two.
