HELP! LOUD ticking/tapping sound from engine
Drove the car yesterday, it was fine. Drove it today there a loud ticking/tapping noise (not the ticking noise everyone gets at idle).
The ticking/tapping noise only happens when gas is applied and when there is load. But when gas is applied and it's cruising at a constant speed it goes away. The noise is synchronized with accleration, as i accelerate faster the ticking/tapping noise is also faster. IT is LOUD, with the windows down i can hear it over my CT mufflers, and when the windows are up, the sound goes through the firewall.
When checking under my hood, the sound just seems to be comming from everywhere, but mostly upper rear on the egine.
Any thoughts? I searched and found common suggestions: engine mount, idler pulley, valve clearance

i dont think its the oil and i use shell top of the line gas too and i get the same noise in my car too. What you can try is Get OUTLAW by Penzoil (Dark Blue) its like $5 bottle it worked pretty good in reducing the noise but its still there ever since i bought the car. I am Thinking its the Fuel Injectors too.

Sounds like the engine is knocking indeed.
I've had this due to some dirty fuel that clogged a number of injectors. I had the dealer flush the entire engine for $100.. runs like a purring cat ever since (and there's no way in hell i'll ever put Thrifty fuel in my cars again)

Well, there's a lot of factors in an engine that can cause knocking sounds
I simply had the dealer look at the car when mine started doing this.. they adviced the flush on what they found.

Yes, try the flush first, if not, it might be a loose piston arm, had that happen to my friends 98 prelude. Does it sound like a ticking clock, and can you feel it when you place your hand on the top of the engine when in idle?
