I have a 2001 Honda Civic LX sedan with 197k miles that has chronic oil leaks that appear to be coming from the valve cover, oil pan, and somewhere on the timing belt side of the engine. It is difficult to distinguish where the leaks are truly originating due to the tight spaces and grime buildup as well as the effect of gravity. The leak does not cause a drastic loss of oil, around every 3-4k miles when I change the oil the level is on the low portion of the crosshatch area of the dipstick and I have not had to add oil before the change. I wanted your thoughts regarding if there is an issue with the PCV system. I think the PCV valve may be clogged or stuck closed causing an increased pressure within the engine thus causing all these leaks. When I did the last oil change I started the engine and placed the oil fill cap over the fill hole and the cap kept being bounced around and off thus leading me to believe there is an abnormally high pressure within the engine. I am fairly certain that the engine has good compression and the piston rings are intact due to a lack of oil burning occurring and typical fuel mileage. I am reluctant to change the associated gaskets because of what appears to be the increased engine pressures and I would rather not do that twice. What are your thoughts? (thanks in advance)

just change the pcv valve. But really engine is probably worn inside, you have compression rings AND oil control rings on the pistons. And they can all wear differently
