I just did a complete rebuild on d15b1. Even rebuilt the 4 speed trans. The problem is that's it leaks out the weep hole between block and trans. I pulled the oil pan and resealed it. Still leaked. Pulled trans again, new rear main seal,...still leaks. It leaks about a few tablespoons when i park the car. If I start the car and let it idle it doesn't leak. Only after a drive around the block it will leak then stop. Sort of like the oil drains to the pan and then it stop. I cannot believe the crank needs to be sleeved or was in poor condition so sealing is bad., Upon inspection the crank surface looked fine. Pilling the trans again would suck as I want sell the car (90 civic wagon base model). Any thoughts out there?
