I have a 2007 Lincoln Navigator that is making a ticking noise.
What is your question?
I had an engine flush done today but still making noise. Can it take a couple days for sludge to clean out. Or do I need to replace valves or lash adjusters and rollers? How much is that? I also had my fuel injector module replaced today as well bc it went out. Runs so much better. That's why I thought maybe it might take a couple days for the sludge to clear out..
