I hae a d16y8 with a oil leak running down the block where the engine code is. I have replaced the distributor o ring and the vtec selonoid gasket. The upper gasket not leaking either. Any ideas I'm unsure it's the valve cover gasket cuz that would be the only spot it's leaking

 

It would not be unusual for the valve cover gasket to be leaking in only one spot..

Try to find the highest place that the oil covers and that will lead you to where it originates. You may need to clean the front of your block abit and run it for a day to see clearly where the oil is coming from.

 

If I wipe down the block and everything there will be new oil on the bottom of the vtec solenoid and dizzy then seems to go down the block
