Hi my 08 Kia Optima is making a strange ticking noise while the engine is running. Mechanic's Assistant: Where exactly do you think the noise is coming from? And how long has this been going on? For about 2 days now. Now the engine light popped on. Mechanic's Assistant: Are you fixing your Optima yourself? What have you tried so far? Nothing so far. I don’t know much about cars so I cant fix it myself

Hi Logan. Nice to see you today! I'm sorry to hear you are having this problem. I know this can be frustrating. Logan, does your vehicle have the 4-cylinder or 6-cylinder engine?

4 cylinder.
Automotive Expert
Great, Thanks, \*\*\*\*\* \*\*\*\*\* would you say the ticking noise is coming from the top of the engine? Passenger's side? Lower section?

It is the engine on the passenger side
Automotive Expert
Ok, great, thanks Logan. Please give me one moment to type out some information for you. Sit tight one minute... I'll be right back!

Thanks for holding, Logan. If the noise is on the passenger's side, there are a few things this can be. This can be a problem with one of the bearings in one of the pulleys, like the idler, tensioner or AC Compressor pulley. This can be a problem more internal, like a loose timing chain. First course of action here is to remove the serpentine belt and run the engine for a very short period- no more than 10 seconds. If the noise is still present with the belt removed, the problem is internal, like a timing chain issue. If the noise is gone with the belt removed, the pulleys will need to be inspected by hand. In the meantime... if the check engine light is on, I would recommend you have the Diagnostic Trouble Codes (aka "P-Codes") scanned from the on-board computer. Many times these p-codes can give much more insight as to where the problem lies. You can have these p-codes read **<u>FREE</u>** (except in California) at any local "big chain" part store (ie. AutoZone, O'Reilly's, Advanced, etc).

Chevrolet released a Technical Service Bulletin about this issue in 2013. TSB Number:PI-1131. It suggests code P2714 may be caused by a stuck or non-functioning pressure control solenoid. If you've eliminated that as the cause and replaced the TCM, then...

Hello. We will be happy to assist you. I believe that the entire instrument cluster may be faulty. It is highly unlikely that nearly all of the gauges will fail at once. I suggest that you have a technician inspect...
Gas is pouring out of the throttle body. What would cause this?
The fuel pressure regulator is leaking fuel into the intake manifold and may have even filled the engine oil with gasoline.

Sometimes when Starting the car it only makes a clicking noise after a few tries to start it, it starts like nothing.
This may suggest a faulty starter solenoid. The starter solenoid is located on the starter and has internal electrical contacts that transmit electricity to the starter. When this fails, it may cause a clicking sound and will not allow the...
I just changed oil and I drove less than 200 miles and the dip stik show low oil levels
