I did install a new front balance shaft seal retainer though. the oil filter shows no sign of leaking either. where is the oil pressure sending unit?

 

The oil pressure sending unit is above the oil filter on the firewall side of the engine. On my 95 it was way above the oil filter and had a one wire connector going to it with a rubber boot around the connection that was very brittle and filled with oil due to age.

 

here are a few pics to go by F22a6

 

thanks for that. I will pull my upper timing cover and valve cover again and snap some pic from there and underneath tomorrow

 

just an update, I have not been able to get under the car yet because it started raining and hasn't stopped yet.
