i was on my way home today and heard a rattling nise coming from up front. figured something was loose or whatever . got home, popped the hood and gassed it a bit and it sounds like its coming from the head. really loud rattle towards the front.

i know honda is known for noisy valves but this is LOUD. any ideas. gonna take it somewhere monday but this is strange. its a MY00 that just turned 26k.

 

Could be a valve gone out of adjustment. Could be a noisy cam chain tensioner. A couple of '00s have been known to need new ones.

 

dunno but it just started out of the blue today. i know my b16 would make some chatter but this sounds like a marble bouncing around. and just after i got told they arent going to help with the holes in the top. YAY!

 

Where you on it at all today?

 

how much noise does a bad cam chain tensioner make? is there any way to know for certian its bad, or must you take it apart and look?

 

I don't know. I've never heard one. I've only been told by other owners who have had this problem that it started out being a noticeable rattling at the front of the engine. Tensioners don't always give much warning when they go. With a mechanic's stethoscope, you can isolate the noise and pinpoint it to the front of the engine face as opposed to on top of the valve cover for a bad valve.

 

chain tensioner is oil feed by oil are you low? also when I scored my #4 cylinder it souded like my valves where not adjusted. but was worse and the car ran and idled fune.

 

the oil light has popped on for a second or so when i come to a stop and the car will idle down way low and the light comes on for a sec then goes off as soon as the car gets back up to normal idle rpms.

 

thats not good. check it and see if noise goes away.

 

I wouldn't be checking the noise, I would be checking the oil level ASAP. It sounds as if the oil level is at least 3, maybe 4 quarts down. I have never heard of an engine oil light coming on with only one or even two quarts down.
