Body is solid, Very very little rust, it has a few dings, but overall in really good shape.
Can you share. I am actually in the middle of putting a 3VZ back together right now for my 88 4Runner and would love to know what they suggest/ did to help the little motor out.
We replaced the crank and rods with those out of a Toyota 3VZ-FE (came in Camry's, they are forged units rather than the stock cast units). Used after market pistons though to keep everything together.
Before machining, they were able to add in material between the block and the water jacket on the number 1 and number 6 cylinders where the head gasket typically blows out.
When I did my 3.0 I did the machine work, replaced all of the parts with new OEM Toyota where prudent (oil pump, water pump, sensors, hoses etc) and upgraded parts where necessary (like ARP head studs, ARP con rod bolts,cometic copper head gaskets). Had the injectors cleaned by witch hunter performance, replaced 2 of them. Replaced the engine wiring harness and ECU.
Plugs, wires, cap and rotor (all new OEM parts). New oil pan. The list goes on.
Though all that said, if your 4Runner has a manual transmission, I would strongly STRONGLY suggest junking the 3.0 and getting a 3.4. After all of the work I put into that motor, time, effor and money, I could have bought a low mileage 3.4 and the
complete kit from ORS (when they were still in business), and come out with a better setup than what I wound up with.
