its a 92 civic(sedan but that doesnt really matter)

i was looking for possible diy tricks and method i could use to overall tune up my engine to keep it healthy.
any bolts i could turn, etc ... anything i could do to make it better and not have to use a mechanic.
if someione could just name a few things and how to do them id be set.
my car is a nice vehicle waiting to be made, just trying to get it as nice as possible, also looking into pressurewashing my engine and such, just plain everything i can do.



thanks for the ear.
