2006 Cadillac SRX Repair Question
2006 Cadillac SRX Timing chain
2006 Cadillac SRX 6 cyl Two Wheel Drive Automatic 53,000 miles
I am worried about a repair job that is pending on my cadillac. The engine light came with the owner's manual saying it was an emissions problem (probably) and to run through a full tank of high grade fuel and check the gas tank cap. I did these two things and the engine light remained on, but was not flashing.
I took it to the local cadillac dealership and they said the computer indicated it was the timing chain - but it was not definite. They also said they would not know until they broke the engine down. I have a great warranty policy through Lexus where it purchased the car, but they cannot perform the repairs.
As it stands now, I may be liable for a hefty bill if they go in and find it is not the timing chain. If the computer says it's the timing chain, but the car is only indicating a slight sluggishness on acceleration with no noise, etc. could it still be a timing chain problem. I am not driving it right now because I am worried it will break destroy the engine (per dealership). Should I take it to another dealership for a second opinion? I have had no problems with the current dealership, but am terrified of them finding a simple problem that is not covered.
Can you offer any advice?
I use synthetic oil but the computer can only be reset for every 3 months oil change, rather than every 6 months. On my last oil change, I was about 4 to 6 weeks overdue on the 6 month oil change date. The filter was dirty, but the mechanic said the oil was very high grade and the engine seemed fine. Could this late oil change have caused the problem?
I did tell the dealership and they did not see any issue with it either.
Check engine light on? yes what was code number? An Auto Zone can scan for code then post will advise. I have never heard of a computer check that can determine the need for hard parts so sounds Fishy.
Let me know
Thanks for donate

Couple of possibilities exist here, they need to determine if the reluctor on the crankshaft has moved. there is a bulletin
#PIP3423C: DTC P0016 P0017 P0018 P0019 P0008 P0009 - keywords actuator camshaft crankshaft mil reluctor ses - (Jan 9, 2009)

This PI was superceded to add more diagnostics. Please discard PIP3423B.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Vehicles with 3.6 LY7, 3.6 LLT or 2.8 LP1 may exhibit two or more of the following DTCs: P0016, P0017, P0018, P0019, P0008 or P0009.
For 2007 model year vehicles with 3.6L LY7 or 2.8L LP1 engine, refer to bulletin 07-06-01-013B for Buick Lacrosse or Allure and Cadillac CTS, STS, SRX or bulletin 07-06-01-014 for GMC Acadia, Pontiac G6, or Saturn Outlook and Aura.
The reluctor for the crankshaft sensor pressed on the crankshaft may have moved. Refer to attached photographs for exact location. If the reluctor has moved then replace crankshaft.
There is also the bulletin that is referenced for timing chains, I have found that this does not just pertain to 2007 vehicles.
#07-06-01-013B: LP1, LY7 MIL/DTCs P0008, P0009, P0016, P0017, P0018 or P0019 (Replace Primary Drive and Both Secondary Drive Timing Chains) - (Jun 18, 2008)
Subject: LP1, LY7 MIL/DTCs P0008, P0009, P0016, P0017, P0018 or P0019 (Replace Primary Drive and Both Secondary Drive Timing Chains)
Models: 2007 Buick LaCrosse/Allure
2007 Cadillac CTS, SRX, STS
with 2.8L HFV6 or 3.6L HFV6 Engine (VINs T, 7 -- RPOs LP1, LY7)
Attention: The bulletin does not apply for 2008 model year 2.8L HFV6 or 3.6L HFV6 Engines.
This bulletin is being revised to include additional information on model years for the third design roller-type chain, add an Attention statement that this bulletin does not apply to the 2008 model year and update the Parts Information. Please discard Corporate Bulletin Number 07-06-01-013A (Section 06 -- Engine/Propulsion System).
Some customers may comment on the Malfunction Indicator Lamp (MIL) being illuminated. Technicians may find the following Diagnostic Trouble Codes (DTCs) stored:
â€¢ DTC P0008 : Engine Position System Performance Bank 1
â€¢ DTC P0009 : Engine Position System Performance Bank 2
â€¢ DTC P0016 : Crankshaft Position (CKP) - Intake Camshaft Position (CMP) Correlation Bank 1
â€¢ DTC P0017: Crankshaft Position (CKP) - Exhaust Camshaft Position (CMP) Correlation Bank 1
â€¢ DTC P0018 : Crankshaft Position (CKP) - Intake Camshaft Position (CMP) Correlation Bank 2
â€¢ DTC P0019 : Crankshaft Position (CKP) - Exhaust Camshaft Position (CMP) Correlation Bank 2
This condition may be caused by stretched 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:
â€¢ DTC P0008
â€¢ DTC P0009
â€¢ DTC P0016
â€¢ DTC P0017
â€¢ DTC P0018
â€¢ DTC P0019
If 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.
The above illustration shows the third design roller type chain (1) (for model years 2005-2006 and early built 2007 -- LY7) and the fourth design link type chain (2) (for model year 2007 -- LY7).
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:
â€¢ Binding links
â€¢ Loose links
â€¢ Loose pins
If 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.
