What is a valve adjustment? I wanted to do one on my 1994 Honda civic ex cuz my friends told me I should do one but I wanted to know howmuch will it cost? And what will it do to my car in performance and gas consumption? My car right now has 155k miles.
a valve adjustment is where the valves are put back into spec, they have a certain amount of space from the rocker to the valve stem, to accommodate for heat expansion every so often that clearance needs to be readjusted, otherwise the rockers can get too close and start to tap typically my friend charges $60 at his shop.
Leave it alone. Besides at 155k a Civic is junk not worth spending money on.
Don't bother if you really don't need it (or don't know what it does). As cars get old, parts wear out and need to be adjusted. The valves open and close to let fuel in and exhaust gas out. unless you are suffering from some problem you don't need it. ==== I have 1994 Civic EX also. The good news is that the valves are very easy to access so the labor is cheap (no new parts unless the valves are really worn. good Luck P.S. My 94 Civic still runs like new and get great MPG. So if you get good MPG and have decent power, you don't need valve adjustment.
