I have no idea where this noise is coming from. You can only hear it when you pull out onto the road and give it about 1/2 throttle it sounds like a tick but deeper....???? I thought it may be a valve ticking so I got some engine restorer and put that in but it didn't help at all.......what could the problem be???? and what will it take to fix it???

So.....you think it's detonation or rod knock?

 

read all of that post, and read the webpage listed there

http://remanufactured-engines.com/page4.htm

and you can figure out for yourself.

 

I still have no idea what it is.....it only does it every so often....any other suggestions???

 

pop the hood and rev it up. is it coming from the engine? or could it be an interior/suspension part knocking against sometihing
