Perfect! I’m sure that’s exactly what it is since my axle just started clicking about a week ago. I’ll get right on fixing that. I appreciate and thank you.This is a textbook VTEC solenoid gasket leak. Of course it's just above the oil filter so it masquerades as a "sloppy job changing the oil". Also, it drips onto the right axle and a bearing, both of which may end up failing as a result (the axle did on mine). Anyway, Honda dealers replace the entire module ($300+), but if you do a good job of cleaning it all up, you can replace the gasket and O-rings for about $20 worth of parts. While you're at it, do the front cover gasket as well. Check out my comment on another post about the same thing:
Hi, I have a oil leak that is getting worse and leaking all over my belt which is sending oil all over my passenger side engine bay. It leaks during startup. After about 5 minutes it stops leaking. Please see photos it looks like an easy fix if I was able to remove it. I cannot because there is...www.tsxclub.com
Look up a couple YouTube videos for how to fix this. I found it easiest to just put a blanket/rug on top of the engine block and lay down on the engine to "comfortably" access the part. You have to have a frame of reference, which is why you need to watch the videos. I detached the bracket holding the power steering hose and with that out of the way, you can reach behind the block and remove the part. I only replaced the gasket and the o-ring on the pressure sensor, but there is a second o-ring to replace as well. Then on the front side, you have to detach the PS pump and the belt tensioner to get access to the cover plate. If the tensioner has never been replaced, I would do that at the same time. Mine was chattering/dancing when the compressor kicked on, and now with the new tensioner it's smooth as silk.
