2005 Kia Spectra

2005 Kia Spectra Automatic 73500 miles

My "Check Engine" light came on. I took it to Autozone and got the following printout:
BBCMP sensor A - timing over advanced system
BBperformance - bank 1
Probable cause
BB1 - Blocked oil passage
BB2 - low oil pressure
BB3 - Failed camshaft actuator
BB4 - Mechanical timing issue.

I called the Kia Service department to ask for the parts and labor estimate on these repairs and they said they didn't know what those codes were! I'd need to bring it to the dealership and pay $90 for a diagnostics test. I then ask for ian estimate on the written description (blocked oil passage, low oil pressure, etc). I got the same answer, $90 and they can't give me an estimate without looking at the car.

Last year, at 58,000 miles I had the 60,000 mile service package which included changing the timing belt.

I'm just trying to get a ballpark estimate on what the repairs might be.
