I just bought a 1971 Kayot Motorhome, 26ft with 318 v8 and dont have any specs for it. Odometer states 60054mi.. I just drove it 120mi home 7 days ago from ohio to Indiana and it drove fine, although it had low oil pressure and the rear main seal was leaking bad. I went ahead and replaced the rear main seal, the oil pump, and the oil sending unit and everything is well. Now, the water pump is dripping/leaking at the seal. I am unsure what kind I should purchase for it. Is it the same as a regular 1971 318 v8 truck/van engine? It looks to be original. Any ideas would be greatly appreciated
