150 HPDI oil pump seal

[parker25]

I have a 150 hpdi it's a Z150TXRC . On cold start up it smokes bad like can't see front of boat bad. motor runs great and clears out after a few minutes, Leaking yamalube out the lower unit. No leaks up top air silencer clean, oil tank not leaking, no oil around the out side of power head.I read that the oil seal on the oil pump leaks internally . My question is how do you tell if the seal is bad and is it a seal or a oring. I don't see a seal in the parts listing Do you know the part #. Thanks Tyler
