Where is this oil coming from?

2008 EX coupe

So I noticed some oil left on the driveway, and I noticed some spots of fresh oil drips and trails at the passenger rear of the engine near the lower torque strut mount:

Automotive lighting Automotive tire Motor vehicle Bumper Automotive exterior

Motor vehicle Hood Automotive tire Car Vehicle

Automotive tire Motor vehicle Automotive exhaust Sleeve Automotive wheel system

Anyone have any ideas what it could be? I’m going to keep looking for it myself, but any suggestions would be highly appreciated.

^ That would be my guess. Very common (and pretty much only) oil leak on the R18's. About $5 for a new Honda gasket. Fairly easy to replace.

I’m having the same issue but I replaced the gasket and still oil is leaking. It’s around the same spot but is a constant drip while running. Any ideas?

I have a 2007 SI
had a similar issue
replaced the VTEC spool valve gasket
still had a leak. Found oil pressure sensor bad
leaking internally. New sensor installed no more issues. Have 270,000 miles. Not sure an R18 has the sensor in the same location as an SI.

Did you check your O-ring on the crankshaft-position-sensor? It seems to be dripping starting from this sensor; very easy to check, probably 5 minutes to replace.
