While checking my Rx 7 2nd Gen, I discovered very slight water dropets in the Oil Filler Cap. What could be the cause? Any of the gasket broken? Engine is running normal, both on idle and high rev. It seem to loose very slight amount of coolant. Any suggestion for cure without engine dismantling?

 

I am burning coolant in my car. Not a lot but an Oz or so every few days. Someone told me I had coolant seals going out internally. As far as I know, there is no cure for this condition other than a rebuild. If there is another option someone please speak up and let us know!

 

Normal. It's condensation.

If you want to check something, test the PCV system as instructed in the FSM.
