I have replaced the upper and lower gaskets, but I still have a bit of oil collecting on the wiring.

Is 91319-PAA-A01 the correct o ring that needs to be replaced? That is the last gasket/ring I can think of that would stop this pesky leak.

 

Yes, that is the oil pressure sensor oring which is near the VTEC solenoid module. Your best bet is to clean the oil leak and check in a day or two to determine exactly where the leak is coming from.

What aftermarket VTEC oring did you go with? Kraken or Ballade or something else?

 

everything has been cleaned up and it is hard to determine where exactly it is coming from. it looks as if it is slowly running down the wires that are related to the oil pressure sensor. seems like it is running down the wires and pools up at the lowest point forming into a drip.

i replaced the lower with OEM and the upper with my 2nd ballade. if this new upper fails i have a kraken in the glove box ready to go.

looks like i'll need to order 91319-PAA-A01 and everything will be sealed up once again.

 

i found a related DIY fix posted on s2ki after confirming it was the o ring
