2005 EX civic D17a2, P2646 w severe driver side oil leak
Did a oil change with Mobil -1 5w20 then added a full quart of lucas oil stabalizer. Have done this before and worked better than ever. But this time around, i noticed 2 pools of oil and a fat line of it leaving to the street. I guessed this happened while i warmed up my car then came back home for somethin. Oil pressure light was flicking on and off like a $%&*, and 6k rpm was just not havin it. I am going to replace the Vtec soli and the oil pressure switch with a proper flush and new oil filter. But my biggest concern is the leak coming from the driver side. Please help a dumb fool out :c
Driver side leak where it begins

So, you filled with fresh oil (~3.7 Q) and then added another quart of oil stabilizer? So you are a quart overfilled (~4.7 Q)? That is not good, take a quart out and try again. I don't care how many times you've done this before, you should never be a quart over filled.
Had to stare at that picture for a good 10 minutes before I could finally make out what it is, top down view of the back of the engine. I honestly would get the oil level correct before worrying about that leak.

Ok, good. You had me concerned
If the oil pressure light is flickering you should have a massive oil leak. I'm not convinced it's coming from the area in your picture. Maybe put the front on jack stands then start the engine and look for the leak?
A friend of mine has a severe leak from the oil pump O ring that seals it to the block. I call it severe because they couldn't drive more than a few hundred miles before losing a quart, yours seems worse than that.

You should have left the VTEC solenoid alone until finding the leak. You're likely only getting that code because oil pressure is too low (hence the flickering warning light). I would cut that connector off a harness in the junkyard (leaving enough wire to work with) then solder it to your engine harness. For the time being just bolt he solenoid back on and figure out the low oil pressure issue.
Check the oil level, make sure it's in-between the dots. Start the car and look for a leak, should be noticeable.
