I have a cts with timing chain problems and one dealer wants to replace the cam chaft actuators and the seals around the spark plug gaskets. Another dealer did not quote those parts and did not think the actuators need to be replaced. What other parts should be replaced while they are in replacing the timing chains.

Do you
have the same problem?

If the chain shoes are worn those should be replaced. Maybe tensioners

The timing chain is making noise but has not broken yet, the car is having hesitation problems, etc. A while back the car fouled a plug but they stated that they did not see any signs of any other issues at that time. No oil was on plug and car did fine until it started this which seems like the same type of hesistation issue as before. No code in computer either time.

It could be low fuel pressure or an egr problem likepartial blockage, but if it's making noise it shold be looked at. The other dealer that wanted to change theactuators may have thought that they were sticking or there may be a tsb on them which I currently don't see. The fuel pressure shold be 55-60 psi. If the plug is fouling then that seal should be replaced if it has done it twice.
