have a 89 honda civic sedan, just currently it started making a slight knocking sound comin from driver side, thought maybe it might be the car needed to warm up a little longer. but its still there. this is my only means of transportation, please any advice and all advice will be considered. thank you in advance.sorry I guess i need to explain more kinda anxious for answers, okay I hear the slight knockin when im driving and and when im in park. my car being a 89 only has 153,000 miles on it. i know its not a blown head gasket ive had that before know what it feels like,! lol...my car isnt vibrating. and its still driveable just scared to drive it dont want to make things any worse.does the knocking sound increase with the engines speed?no it doesnt sounds like a constant knockin. and does it sound like anything is loose? No doesnt sound like it to me.how does it drive besides the knock. was runnin fine before then.
