Hi Larry,thanks for your reply.I moved the car after it sat in the garage for an hour and was stunned to find a large puddle of oil
I lifted the aircleaner cover and it was oil soaked again but this time it was clear that the oil is entering at the vacuum intake line.I also looked under the dash quickly (I've had the under-dash trim off trying to find my water leak,but that's another thread)and found it oily at the climate control area (towards center of dash on driverside).I will not be driving it until I sort this out,but my wife might object to my taking her truck
I can't see the oil coming from anywhere else,but I've been wrong before.
