One owner car – regularly dealer maintained until this past week. Wife took it into dealer to diagnose intermittent creaking noise in front end. Came back with a diagnosis of struts, leaking power steering pump and leaking oil pump seal – which we had been unaware of any leaks – nothing ever on garage floor. Car has been maintained at the same dealer it was purchased new in 2007 and has 204,000 miles. This is the wife’s daily driver. I used to do all the car maintenance and big repairs on the German cars we owned for decades, but have not touched this Honda until this past week to install new front struts and front brakes, and to trouble shoot this oil leak to decide if the car is worth repairing. Plan on doing valve adjustment, spark plugs, timing belt, water pump, and power steering pump if I can find/fix the oil leak. I have removed the timing belt covers, timing belt (which was dry- amazingly no oil on it) and the crank shaft sprocket pulley (Please see video at https://youtu.be/0jzFEun_5wI ). Both old and new oil is on numerous places (could be power steering fluid mixed in with dirt and old oil), but new motor oil also appears to be coming from above the oil pump (please see attached video). Any help would be appreciated.

I make no claim to be a Honda expert but it appears you may be leaking from either the oil pump itself or perhaps the gasket.
It appears from your video to originate from the area marked.
May also be a valve cover gasket.
Seriously though….
Never trust your life under a car with a scissor jack only.Advice: Don’t get under the car with it solely supported on a scissor jack, use jack stands unless you want to get crushed.
Fixing the leaks:
1.) Drain oil & replace seal on leaking oil pump where it mates to the block. While you’re in there check and replace if necessary the cam and crank seals. Don’t forget the timing cover gaskets themselves if they are all covered in crud and leaked oil.
2.) Check the oil pan gasket (those leak over time) and valve cover gasket(s).
3.) P.S. Leaks are a bear to find so what you might have to do on that one is fill it and have your wife or another person turn the wheels lock to lock with the engine running repeatedly until you see the leak. Chances are a new/rebuilt QUALITY pump may be in order.
4.) See Eric’s many strut replacement videos for details on checking for strut wear & damage, etc.Dudes. The scissor jack is not holding up the car. It’s supporting the engine. To pull the timing belt on an Accord, you have to remove an engine mount.
Yes, the s-jack is just to give additional support to the motor since one of the four (4) mounts is removed to gain access to the T-Belt procedure. The car is solidly on floor jacks, with back ups and the back wheels are chocked.
Honda oil pan does not have a gasket, per say, it is sealed only with Honda Bond sealant. If I pull the oil pump the pan comes off first by default, and so any leak that might be there would be fixed by process of reassembly.
But the leak appears to be coming from ABOVE the oil pan seal.
The question is what other areas of the motor and/or o-ring connections to components and/or seals on this particular engine (Honda V6 2007 A/T Trans) can produce the fluid leaks present in the video.
I just returned from a Honda Dealership parts department and one of the techs viewed the same video posted. He said it is both the water pump seal that has failed and the oil pump seal that has failed.
Can other areas of the oil pump (besides the oil pump seal) leak? Is it worth replacing the entire oil pump on a 200K car?
I’m not sure if your car would be covered, but there was a TSB that referenced hairline cracks, or porousness in the valley of the block.
There was one for the Civic 1.7 and another for the V6. Again, can’t recall what models exactly were effected by the V6 TSB.
