I'm a mechanic. Customer complains of a constant 'knocking' sound in the engine. He has taken it to other mechanics who have put in all sorts of new parts but it still makes a noise. Never worked on Kia before. What do you suggest?
Engine knoking could sudjest that their may be water in the gas tank, Cylinder head may need spring adjustment or it may need the most simplelest thing... the CORRECT type of oil change. Electricaly you may whant to check the sparkplug cables and distributor or modulle, sparkplugs or any relay that could cerrespond to the gas pump. Finally check the engine for timing, timing belts or worn sprokets.

This sounds suspiciously like one or more of your engine mounts have deteriorated. If this Is Indeed the case, and It has been going on steadily worsening over time, I would advise you to replace all four.
I often find when having problems with my car, that seeking advice from a local car spares supplier before going to a mechanic can be helpful as they are less Inclined to give the sharp Intake of breath which often accompanies the garage quote...!
Your local auto parts store, or auto parts superstore should have it, if not, be able to order it. Ex.--Advance Auto Parts store has a BWD Knock Sensor, #S8815, for around $50.00. 2002 Kia Rio 1.5L/L4/FI
your post is 1 year old. i started helping others 1 week ago. as a fellow rio owner im here to help there are currentl over 5000 un answered posts. if you still need help re-post your problems .its free to get your check engine light checked at most auto parts stores . write down the codes and meanings. 03 kia rio's are blue booked at about $500.
if you re-post with a code you can get faster help. if your car dont have a code . its hunt and guess . my guess would be throtle position sensor,knock sensor or mass air flow
A knock sensor is simply a microphone that is screwed into the engine block. It is there to listen for pinging or engine "knock" that is caused by poor fuel or extreme load. When the computer hears the knock, it retards timing, which in turn reduces the tendency for knocking, however, it will reduce power to a certain extent as well. It is possible that a faulty knock sensor can be telling the computer to ****** ignition timing too much, it is also possible that there is a mechanical problem within the engine that is mimicking the sound of knocking and retarding timing as well.
engine noisy,used one of them sunday mechanics code readers and reckon you know it all now ???only one cause of a noisy engine and thats because its been run with no oil,or had the guts thrashed out of it,or a pulley tensioner bearing run dry,clutch thrust bearing ,water pump,in fact anything .GET A PROFESSIONAL TO LISTEN,call a local mobile mechanic for an opinion then ask how to cure it on the cheap.
It,s probebly that the knot that holds the bearing in plase is being plased too tight, It,s the oldest trick in the book... this way you will have return about every two or tree months to get it fixed, and so the mechanic can keep eating.
