I bought a used 2007
Hi,
If you have check engine light ON in this model, i would advise you to seek a dealer ASAP. as there could be many reasons. He would need to diagnose and scan the car. On the basis of that, he could tell the exact diagnosis. However, as you want more details, so below is the most probable cause ( again you need to get the car scanned ) :-
Subject:
LP1, LY7 MIL/DTCs P0008, P0009, P0016, P0017, P0018 or P0019 (Replace Primary Drive and Both Secondary Drive Timing Chains)

Refer to SI for the follow diagnostic information if only one of the following DTCs are set:
•
DTC P0008

DTC P0009
•
DTC P0016

there are more than one of the above mention DTCs set, inspect for
stretched timing chains. Refer to Camshaft Timing Drive Components
Cleaning and Inspection (Fourth Design) in SI.
It may take several thousand miles/kilometers of use before the
timing chains begin to stretch. Inspect both the primary drive and both
secondary drive timing chains for the following:
•
Binding links
•
Loose links
•
Loose pinsIf any of the chains are stretched, replace the primary drive and both secondary drive timing chains only. DO NOT replace any of the other timing chain component parts.

If the oil is not leaking from the engine ,it is being burned by
the engine.This is common in a lot of the Cadillacs.most of the time the
piston rings are stuck with carbon build up & cleaning the upper
combustion with top engine cleaner will take care of it.
There are no recalls on timing chain stretch or camshafts for this vehicle at this time.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
