1994 3.4l - slight little Oil and Coolant leak

[Mstg007]

I have had my convertible sitting in the garage for the past few weeks. I noticed a few drops of oil and alittle coolant to the side of the oil. Dumb question is there a sealant I can add to the engine to keep it from leaking?

[Schurkey]

How about actually diagnosing and then FIXING the leaks?

New gaskets dude, there are no short cuts. You`ll have to find out where its coming from and go from there. Many places oil and coolant can seep out of a 3.4.

Let's start a list of the "usual suspects"

 

OIL LEAKS

1. Oil pump drive O-ring

2. Oil pump drive O-ring

3. Oil pump drive O-ring

4. Oil pressure sending unit.

5. ???

 

 

COOLANT LEAK

1. Intake gaskets

2. Upper-to-lower intake manifold O-ring

3. Heater hose quick-coupler near thermostat

4. ???

#4 Happened to me. That tiny hose that has the clamps and is a bitch to get off leaked on me once. It took me a while to figure out.

 

This one is directed to the OP, but if you have a leak, trace it! Don't just look at the puddle, look at the pathline. Leaks usually leave a pathline from where they came from. My lower intake manifold leak did this. I traced it back to the rear bank lower intake manifold.
