What's That Ticking Sound Coming From Your Car's Engine?

Apr 18, 2014 - My engine has developed a strange ticking sound. Its whisper-quiet before an oil change, and then makes a loud tapping ... Even more strange: The engine is muffled when its cold but noisy when its warm. .... Whether they were great or not, these cars have some cool names. By Collin Woodard · Trucks.

What do you mean "parking sensor"?
Do you mean the parking brake is on, or is the seat belt not being used?
You should be able to tell where the sound is coming from.

It needs a valve adjustment. I am guessing about $150.

A pain on the Subaru because you have two banks of cylinders and each has a set of valves. Also, access is kind of difficult as they push to each fender.

A lot of times a ticking sound is the valves, which usually means a valve job when it gets bad enough.

But if it is a gentler tick sound it could be what is know as a wrist pin knock, which in some cases is not a big deal and others a big deal.

If the sound gets louder and louder, you will have to do something about it. But if it stays pretty constant then you monitor it, and look for other indications such as losing power, excessise oil use, etc.

Noise out of the engine. Noisy valves? Low oil level? Is the sound like tick, tick, tick, tick......that's how bad valves sound. I don't know if you have solid lifters those have to be adjusted after some mileage. Hydraulic ones are self adjusting. Only a good mechanic can tell for sure.

Check Park lock , probably needs replacement or adjustment

You probably have a bad outer C\V (constant velocity) joint on either the left or right side. The typical fix is to replace the entire axle but you should not need both replaced, only the bad one.

make sure that you have the springs in the right positions. look very closly. i had the same problem one time and it turned out that i had the sprng in backwars and it was striking the drum. the best thing to do i drive it for a while like 10 15 miles kilomerts and then take off the drums again. look around for springss that are worn shiny paint missing. it could also be a piece of rust caught in there somewhere

difficult one this without haveing a drive in car to hear the noise,this sort of sound could be caused by the flex plate on the crank/torque converter,break on edge of fan belt,power steering pump,altenator bearing,evan the transmission possibly a pump,or could it sound more a sort of electro mechanical noise ?? without hearing it its very difficult to diagnose .

It is part of the waste gate just above the gas tank. It periodically checks for leaks and pressurizes and releases. Gives a ticking noise when it does this. Not a problem and GM is aware of this and said its normal on our cars.
