So today I decided to get the Rx7 on some jackstands in order to reduce the negative camber on the front wheels.

Since it was already up I decided to take a look at what was causing this very small puddle that my dad saw.

Here is a picture of the puddle. You can see that its near the oil pan area, but I don't think its oil.


I took some pictures of the suspect areas.



Any idea where the leak could be coming from? Its no that much, but a leak is a leak and I want to fix it. It seems that green fluid is coming from between the corner of where the transmission bolts to the engine in the 2nd photo of suspect areas. I'm not sure if that is where the leak is coming from, but it is accumulating there before dripping. If its green I was thinking it would be coolant right? I really hope not. Any ideas of what could be leaking in that area.

Also another thing REALLY bothering me. Shouldn't that hole seen in the 2nd suspect picture be covered by a drain plug or something.
Here's another picture


I'm pretty sure a drain plug is supposed to go there..... This means I was right to suspect that my transmission had low oil. Or no oil.... Hopefully there isn't significant damage as it shifts pretty smooth still. Any idea if there is supposed to be a plug there? If there is does anyone know where I can buy a plug?

 

Yes, green would be coolant. Probably not the best idea but if you get a little on your finger and taste it, if it has a sweet taste it's anti-freeze( that's why animals drink it ). That hole should have a plug but no liquids should come out. I think is just an inspection hole for the clutch/flywheel. In acouple of the pictures you can see the teeth of the flywheel. Under the oil filter is a coolant hose for the heater. I'd start there.

 

It looks like a coolant leak from somewhere above. The rear iron to TB water line, or either of the heater connections could get that area wet.

There probably could be a plug there on the bottom of the bell housing, but what you're seeing is just the flywheel. There's not supposed to be oil in there. The clutch wouldn't work too well if submerged in oil. There's a flywheel inspection cover on the top/rear of the engine that can be removed to look down into the same area.

 

Okay, glad that the hole is just a inspection hole for the clutch/flywheel. Should of realized it because it makes sense when you think about its location.

I'll try tasting the leaking stuff and start searching for leaks once this rain/hail lets up. Stupid norcal weather doesn't think its summer yet.
