@dranobob :
So the engine has been sitting for two years with a blown head gasket?
Did you find coolant in the oil back then?
Did you remove the head, find coolant in the cylinders?
Point is, if coolant has been sitting in a cylinder or two, those cylinders might be corroded/eroded from rust which means at a minimum
the cylinders would need to be bored out (larger). And if you do that you would need new larger pistons, new rings, etc.
And if coolant was left in the oiling system that could also damage the bearings, which also means the engine has to come apart
new bearings, etc, etc.
So you may end up with a money decision, either rebuild the entire engine or buy a new short block and maybe just rebuild the head.
One less painful route may end being to buy a new Toyota short block (
11400-66041) ie: new block with pistons and crankshaft already installed
by Toyota in Japan. If you plan on keeping the vehicle a long time consider replacing the valves and springs and if the head is warped, get a new head also. Some of the above (quality, cost, etc) depends on who's rebuilding the engine/head and their experience level, attention to detail, etc,etc.
You also may want to replace the timing chain slippers, timing chain, timing chain sprockets, oil pump rotor, oil pump bushing, harmonic balancer, rebuild the power steering pump, replace every vacuum hose under the intake, every water hose, clean (hot tank) the intake manifold (inside the runners and EGR port/tunnel) and valve cover, send the fuel injectors off to be cleaned (most of those connectors may crumble), clean the throttle body completely, ---- (and about 47 other items while you're in there).
Expect/plan on more harness connectors to break; most are still available but one other consideration is to buy a complete new main engine harness
while they're still available and while everything is apart. Besides the connectors crumbling the insulation of all the wires eventually develop cracks after 30 years in the hot engine bay.
FWIW
