Coolant leaking from rear of engine where the passenger side head and intake meet the block.The engine seems to run fine. is there anything under the intake that could be damaged or do you think its a head gasket

There are three plugs on each side of the block under the exhaust manifold and two in the rear of the block between the engine and transmission. If the rear freeze plug is leaking, it can be seen by antifreeze leaking out of the bottom of the transmission bell housing.

There are none. The Transmission does not use water to cool it.

On the block ( the bottom part of the motor ) below the intake manifold

Hello, there is a coolant transfer pipe under the intake manifold, it connects to the front of the block under the manifold and exits at the rear between the heads where two hoses are attached for the heater and one for the throttle body, one of these may be leaking, in some cases the transfer pipe is rusted and starts to leak filling up the chamber between the heads until it leaks out at the back.

Head gaskets never give a problem on a 3800 engine it's always the upper intake that is the problem. You may check your lower intake gasket where is meets the head. They will leak there too. Check the hoses , plastic elbows, freeze plugs etc. I usually find the leak with a flashlight after the engine is hot , then you will see the steam from the leaking coolant. Get the car on a lift etc.

The first thing is to locate the coolant leak, you will need to pressurize the cooling system to locate the leak. these cars are famous for intake leaks, coolant and oil so take a good look at the intake where it meets the head, if theres coolant getting into the cylinder that may be the cause of the misfire. good day.

It is more likely a leaking intake manifold gasket. This is a common problem, they are made of plastic.

Have a look for a heater control valve that may be leaking in area near firewall on passenger side, just follow your heater hoses.

might be a freeze plug leaking, or heater hose. there are three freeze plugs on each side of engine and two in back of engine. most likely if any of them are leaking, it will be the one behind the starter on the far right rear of engine block. they have also been known to leak around the front and rear of intake, where intake, head, and block meet.

head gaskets can\will leak between the head and block. I would also check where the intake meets the heads. But normally if its leaking there itll get into the oil.check for puddles where the intake meets the block in all four corners of the intake. At the beginning of the cold weather did you have good coolant in it? you may have a freeze plug partially popped out.that,normally that will be caused by weak coolant but they can pop out by age.A freeze plug is a much easier fix than head or intake gaskets.
keep me posted thx.......
