Hello, I just bought my 2000 Xterra SE 4x4 5 speed, about a month ago. I bought it with 245,900 miles for $300. The previous owner said it had a blown head gasket. I decided to take on the project and bought it, after I inspected it I found that it was only a leaking heater hose. So far I've performed a tune up, changed all the coolant hoses, timing belt kit, water pump,replaced a broken passenger exhaust manifold, relocated the knock sensor and replaced a left rear broken leaf spring. I had to gut the interior and pressure wash the seats since the previous owner was a smoker and messy coffee spiller. Eventually i plan to do a PML and 2 inch body lift and 33s. Thanks for all the great info.
