Point of story: compression test can tell you how worn your piston rings are only if you adjust your valves before the test.
So per this post and shmoos below I'm thinking (since I already within last 6,000 miles had valves adjusted) if I get a leak down and compression test I should be able to determine what needs replaced. And if its rings or valves then if I just do just those my engine may last me a considerable amount of time longer without a complete rebuild or swap or major work like that, does this seem right? Also since I have absolutely no ability to work on my car or do tests how much can I expect to pay average to get both these tests done at a shop?
Please reply, and thanks for all your posts.
