A pre-cat can't leak. Not fluid anyway. What truonghthe was referring to was oil leaking from the front valve cover onto the pre-cat, and likely along the side of the engine.

I mean, it's already pretty bad. Oil can ignite. That pipe is probably reaching temps of 100 degrees or more.

That's one concern.
Another would be loss of oil and could potentially starve the engine of oil.

Fix it sooner than later

Assuming you've already checked from the top where it might be originating from to pin point whether its oil from the timing belt area/covers or elsewhere. On my 07 TLS AT, the PS Pump was leaking from the outer case seal and the low pressure hose enough that itd make its way behind the alternator, by the ac compressor and down the side of oil pan and by the front converter. Looking at it from underneath itd be hard to mistake it for oil until you swiped it with your finger and smelled it.

if its oil then I would fix that ASAP, especially if it power steering fluid. Any veteran member here probably remember consequence PS leak in this video.

BTW looks like Acura paid the owner to have the video removed from youtube.
