The sound goes away after driving for awhile, and you only hear it after the car is initially started. Could it be the oil? I had the pipe before the muffler replaced two years ago. Could it be loose? Thanks!

Ticking & Rattling Noise is due to the following reasons:
1. Engine Rubber Mounts (Solution: Get them replaced)
2. Constant Velcoity Joints---CVJ (Solution: Get them replaced or greased---there are steel balls in it which may rattle)
3. Steering system (Rack & Pinion): Check for loose Inner Ball Joints as well as Torn Rubber Bellows (which means there is dust, foreign particles between moving parts)
4. Steering System(Column): Loosened parts.
5. Engine Tuning Out.
These are primary reason, eliminate one by one and you will come to know the root cause.

Sounds to me like your engine is pinging. You can do one or both of these suggestion to fix the problem. The easiest is upgrading to a higher octane fuel to see if it eliminates or helps a little with the noise. The other thing is you may have a clogged EGR valve/ intake manifold from all the years you have been using a low or poor grade of fuel. You may need to take your car to a local garage and have an induction cleaning of your fuel system. This will cleans the plugs, valves, cylinders, fuel rail and part of the EGR depending on how clogged up it is. This service can run up to $75-100 depending on what kind of car you have.
Also if you are low on oil or if the oil is dirty or the filter is dirty, the lifters may be clogged too. Try a can of Marvel Mystery fluid in the crankcase. This will help clean the internal lifters of the engine. Check the level of your oil when it is cold.

Without hearing it, it is hard to tell, but my best guess would be a valve lifter. Depending on the year and make of the vehicle, the lifters may be slightly clogged. Start with a fresh oil change and see if that makes a difference. There are ways to remove the sludge in the motor, but the best thing is to do regular oil and filter changes!

Most likely it is octane knock or valve train noise. It's hard to answer a question like this, I dont know what kind of car it is. Does it have a turbo or a super charger? Is it fuel injected or car-berated? It could be anything...

It's likely a pushrod or slight ping. I'm not a mechanic though so I'm not sure if theres a quick fix or if you need major work. My car does this about once every ten times I drive it, I just accelerate semi-hard until it goes away.

danger is its the exhaust tipping off the bottom of you motor vehicle. Its an common difficulty thats actual fixed. Get it up on a ramp and examine all the bushing or start up it to come back across precisely wats making the noise.

Good old Spark Knock. Either bad gas or just too low octane gas being used. Try another gas station first then if it doesnt work move up to a higher level octane fuel

Motor mounts or worn valve rockers or lifters.
worn valves a thicker oil would quit the problem.
