I've got 207K miles on my '99 4 cyl vtec and have the timing belt off. Replaced the cam, crank and balancer seals. I definitely had cam shaft seal leak with oil dripping down into lower cover. I think the balancer seal was also leaking but it's hard to tell if the oil pump seal is leaking or if its just some sludge from top of engine. Can I just remove the front plate of the pump and replace the seal or is it more involved?
