'01 Cadillac Deville Issues

Recommended Posts

Hey Ya'll,

I'm a new member after picking up an '01 Cadillac Devill with 62K on it. Two questions:

- Withouth addressing the Northstar V-8 what appear to be common issues with the car?

- Regarding the Northstar V-8, based on seeing oil pooling when I look from the top (underneath the hood) down, .there is an oil leak above the oil pan. What could be causing this and what repair steps should be taken.

The 01 could have problems with its crank sensors, intake plenum and CAT we have found.

The oil leak could be many many things, get it inspected. It could be a simple thing such as a loose oil cooler line or CAM covers to a more serious problem like the case half seal. But there are a host of problems that could cause oil leaks
