While I had the valve cover off, I replaced the o-ring on the cam angle sensor with a viton ring. This normally is quick and simple, but I have the supermiata coolant reroute.

On the 1.6's (CAS on the intake), the shifted water temp. probe blocks the CAS withdrawal. Removing the cam cap gave just enough wiggle room to slip by.

CAS o-ring was only a little leaky but it's time was definately up, snapped when prodded. Replaced with a viton ring.

Half done with the cooling kit: rad is in, reroute is in, FM overflow in. Just fighting with some old hoses, which is proving to be more of a bother than getting the orange piece on the back of the motor.
