Drip Drip Drip

While rolling around under the Miata Friday morning doing a visual inspection, I decided that the oil leak from the CAS O-ring was not the only leak. There was a drop of oil on the front of the oil pan. (I cleaned up the oil pan while I was working on the clutch last week.) So it appears either the pan seal or the front main seal.

I thought I had replaced the front seal last year when I did the timing belt, but after reviewing last years write up, it appears I skipped it. I guess I didn't want to loosen the oil pan at the time for fear of creating an oil leak. Doh! Here's to hoping this is the only leak. I am currently debating whether I want to fix this one any time soon. The parts cost will be negligible but time wise it could kill a day.

I also had a drop of anti-freeze on the radiator drain valve. I had noticed this before also. I think the drain plug just needs to be replaced. This can wait until I replace the front seal, assuming I do, as the radiator needs to be removed during that procedure.

I keep asking myself why I am so obsessed with the car leaking. Why can't I be satisfied just sliding a pan under the car? Myself never answers.

About the time I was finishing up the inspection of my car, David arrived and we replaced the o-ring on his '91 Miata also. Having done the replacement on both a 1.6 and 1.8 liter engine, I believe the 1.6 is a slightly easier task. (It is actually possible to get the CAS out from between the engine and firewall.)
