Went to the dealer with a knocking sound. they first stated that the oil was low and that they need to change and flush the oil. the knocking sound was still happening, so they told it was the timing chain.
Are these two things related?
Yes and no. If the oil pump is going bad the Connecting rods will knock. The Timing chain could be making the sound if the Chain guide came free. My guess is you have a 7 - 70 warranty and they are trying to get out of rebuilding your engine.
Testimonial: "Thanks we have an extending warranty but they want us to pay for the oil flush"
perhaps theTiming chain nylon guides are cracked this is a common problem with this engine.

My 2005 Nissan Quest had a knocking sound coming from the front area mainly on right and left turns. You could feel it at the drivers feet. We took it into the Nissan Dealer and they repaired the Lower Control Arm Bushings. Plus complete 4 wheel alignment, which included a comprehensive inspection of the suspension and steering linkage.
Also replace Oil Cooler O-Ring. Mileage 71,756.
After leaving the dealership, the knocking is still happening, just not as often. Next Day returned the Quest to Nissan, and now they say it is the Timing Chain at another $1,200.00.
How can it be one thing day one, and a new repair item needed on day two.
I was informed by a Nissan Sales Rep the Timing Chain should not go out until approximately 105,000 miles.
