replace head gasket
The most likely cause is a blown head gasket.

It is behind the timing case cover behind the crankshaft pulley.You have to remove the timing belt to replace the water pump for this repair.
mazda b2000
The engine oil capacity for a 1986 Mazda B2000 is 4.1 quarts.
intake? carb or injected (b2000,b2200 or b2600i) b2000 and b2200 pull the air cleaner and hoses ( watch were the vacuum lines go and unhook the little white 2 wire plug on the front) remove the fuel lines from the fuel pump ( on the pass. back of the head) remove the top and bottom manifold nuts. remove the throttle cable ( try not to loose the spot were it is on the shaft. you might be able to wiggle it out of the holder) you can use a long extension to get to the under side nuts and pull the bypass tube back out of the way. pull the manifold back and clean all of the old gasket off . clean the head and put new gasket in DRY (do not use silicone or gasket compound)
I believe the carburetor is a Mikuni. I have a 1986 B2000 myself.
No, it is carburated. If you remove the air cleaner cover it will have a opening with a flap inside it.
