Okay, I recently changed spark plugs, I was planning to check valve adjustment at the end of oil change interval, but I had some time to kill this weekend. Also I've gotten a new tool (3/8" M12 Stubby and ratchet) so that I can try while working on my car.
I bought this car in May 2017 at 63k miles. I used VWB 5w30, Napa 5w30, PYB 10w30, PUP 5w30 x 2, PUP 0w20 x 2, TGMO 0w20, and currently M1 5w30 EP, respectively. First three OCIs were very short as I didn't know service history of the vehicle, but I usually keep OCIs around 10k kms (6k miles). So I am not really brand loyal, I like to try different brands but I'd definitely go with any decent brand if I find a great deal.
For the record, almost all exhaust valves were tight (one was too tight), and 2-3 intake valves were loose, others were fine. Glad that I checked. This car is not even driven hard, but if it was an SI or any kind of performance oriented 8k+ rpm K20, I would have done it earlier.
I also changed valve cover gasket, it was not in a bad condition, but wanted to change anyways as it's 12 years old. Changed it with Felpro gasket, I hope it lasts as long.
Here are some pictures.
Interesting vtec system. It disables 1 intake valve per cylinder for better fuel economy, and no vtec in the exhaust cam. It's good to see there is no scoring on cam lobes, just a little discoloration.
Before you say anything: I cleaned the dirt thoroughly (where cylinder head meets with the intake manifold) before I started adjusting the valves to avoid contamination.
Thanks for your time.
