The PVC valve is located ring in the center of the valve cover on your engine. It is not likely to be bad, but they are cheap and easy to replace, just pull out and replace. I just replaced mine on out 97 Accord.
This engine is prone to leaks around the distributor shaft (just needs a new o ring, not a new distributor) and the oil pump. The oil pump can be taken care of the next time you have the timing belt changed.
What oil are you using? If you are using a 5w30, I would suggest changing to a 10w30. The 10w30 tends to not burn as much for engines with low oil consumption, doesn’t make much difference on engines with high oil consumption or on leaks.
Tester, question for you. While I am not recommending 15w40 for this case, why do you think it will increase wear? 15w40 is a diesel rated oil and contains anti-wear ingredients that have been found harmful to catalytic converters, but as anti-wear ingredients, many consider them superior to what is available in oils for gasoline engines. You have some new information?
