Replaced the front crankshaft seal last weekend and took a couple of shots of the valvetrain. This was exactly what I saw without wiping anything down.

I got the car with 120,000 miles on it from the original owner. It has 140,000 now. I don't know what the PO used, but it had a Pennzoil sticker on the windshield. She told me that she had it changed every 3000 miles.

The engine had M1 HM 5w30 in it for the last 5000 miles. This is what the engine looked like at 125,000 when I changed the timing belt.

These are tough engines especially considering it takes only 3.5 quarts of oil during a change.
