Good morning I have a NXS C15 acert with over 1 million miles I have excessive blowby and when I'm climbing up the hills It struggles under a load.. It looks like it has some oil leaking from the blowby tube and when I start it I see white smoke coming out of the stack.. my mechanic told me its time for a overhaul I just came here for a second opinion but I'm leaning towards and overhaul as well but if that is the case what is the preferred overhaul kit to get
Possible rebuild?
