Hello Scotty. I really appreciate your insights, you have been very helpful so thank you. I am trying to baby our cars 2012 Nissan Sentra SL 102k miles and a 2013 honda odyssey lx 106k miles.

Everything is working great on both, now my question because of their age and mileage:

Should I replace the spark plugs? just as preventive maintenance (The Honda is easy to take the spark plugs and check, but the Nissan you have to remove everything to get to the spark plugs - so I am thinking I will change on the Nissan and the Honda I will just check and change it if I should adjust the valves on it)

As I replace the spark plugs should I work in adjusting the valves? (They don't seem to make any noise)

PS: I am babying the transmissions- changing the fluids with the Honda and Nissan fluids. I also recently changed the timing belt, water pump on the Odyssey. I also change the fluids such as the steering weel fluid. I am planning to replace the driving belt and tensioner on the Nissan since the schedule maintenance call for it and it looks like it is worn out.
