on the 89 accord oil pan what is the hose that goes to it called i have one that leaks oil there .Thanks

I assume it is the one one the back side of the oil pan. That is the PCV hose/"grommet". It comes off the oil pan up to the intake, there is a "lip" thatslips into/thru the hole on the intake, the pcv goes in from there. Last one I replaced I had t get from the dealer. Not that bad....but then I have to ask what the actual problem is?
