tune-up is regular maintenance, I know.
but I have a old, tired engine with 168,000 miles on it. I'm trying to put off replacing the engine for another 6 months to a year for financial reasons. In the meantime to help it last longer & run ok, i'm trying to do some maintenance things I know it needs-the valves need adjustment badly-so I was gonna get a basic tune-up that includes valve adjust, dist cap/rotor, spark plugs, air filter & oil change that will cost slightly less than $150...
Does anyone think its really unnecessary considering the unavoidable engine replacemnt? Thanks in advance for the help.
