HelloCustomer Do you know what kind of fluid is leaking and the approximate area that you are seeing the puddles?
Your JA Expert,
It is under neath the distributor or ignition system mostly in drivers side
Is it black or brown like oil or green like antifreeze?
its green antifreeze
There are a few possibilities. If it goes all the way to the top of the engine, it could be an intake manifold gasket. If it goes inside the the transmission bellhousing bottom cover between the engine and the transmission, it will be a freezeout plug, but you will not see any leakage above that point. If you can trace it up the side of the engine, it could be a freezeout plug on the side of the engine.
can I just fix that my self and where can I buy that plug?
If it's a freezeout plug, its not so easy. These are metal plugs that are pressed into the engine block. Sometimes the are visible, other times they are behind the starter. If it's between the engine and transmission, you have to remove the transmission to get to it. Before you assume it's a freeze out. Get a good light and look in the back of the engine from up top. Look back by the distributor and see if you see coolant. Especially in the pockets at the corners of the intake manifold. Look for any signs of coolant. I'm thinking, you have an issue that is more like an intake manifold gasket than a freezeout plug.
