Well, since we are trying social distancing, I had a lot of time today at home to go through my records: And I found back in March 2019, at 107k mi (approximately 5k after timing belt / valve adjustment work was done in August 2018, at 102k mi), I went to Autozone for P0302 code, Cylinder 2 misfire. My mechanic noted they "Loosened #2 Cylinder a few thousands of an inch , reinstalled valve cover, started engine, watched cylinders with a scanner, no misfire is occurring on any cylinder" at no cost since I had paid $250 the first time I got the valve adjustment done. Although I remember him commenting on this valve clearance issue, I would imagine that if he had seen any cam issues he would have let me know at that time? He is a very experienced mechanic who owns this Honda/Acura only shop.
This happens to be the same P0302 code that was in the class action lawsuit, but until that time I never had issues with the engine and the oil consumption, and it happened after my mechanic did the adjustment, so I would not stand a chance.
Given the confusion over how the economy will do in the short term, we really are not in a position to upgrade our car, so I am thinking that I will just bite the bullet, have my mechanic take the top off and see what's wrong. And Cujet is correct, it's not too terrible but it's there so if I am trading it in at a Honda dealership I am sure they will notice it. I hate to throw more money in but at this point I've spent too much on the timing belt/valve adjustment/tires etc. There is also a whine in the transmission, we did the 3xdrain fill last time, it helped but that may be on the way out, too. All these happening on a Honda that's been serviced for everything that's in the book makes me wonder about buying another one. We've had five Hondas that have been fine except some transmission issues, but I was hoping to get more of this Accord.
