Question type: Maintenance & Repair

Ok I've replaced the rear main seal but I still
have a leak it look like it's coming from the
back of the motor by the distributor  or up
some were by the top of the bell housing  I
can't see it also replaced the oil pan gasket

Could be an intake valley seal, or a distributor o ring, most of those leaks are seepage leaks as there is not any pressure behind them, if it is leaking a lot of oil with the engine running then it is a pressure leak and needs repaired quickly. You didn't state an engine so this is kinda general

It's a v6 2.3
