Ok so last nite it started making a noise its kinda hard to xplain it looks like the noise is coming from the lower part of the motor its like clack clack clack it has the same noise at all times i really dont think is coming from the valves but i will do a valve adjusment soon could it be knocking ? is the piston hiting something ??

how would i be able to diagnose ? it a jdmB18c

I changed the spark plugs, the injectors lookd clean, it idels good the only thing left is the fuel filter but i dont thing it would make a diff.

 

Clacking from the lower part of your motor, eh?

Knock*knock, whos there?

your rods.

Id get that checked out right away at a mechanic, they would be able to diagnose it better than HT can based on your explanation.

 

Rods ?/ any other opinions so i'll have to take the head and pistions out preaty much rebuild it ?

 

help!

 

Holly **** so i took out the oil pan last nite every thing looked fine other than a hella fine almost gold dust ! i didnt find pices of metal ...i took the oil pickup line and the cover so i can see the crank i moved the fly wheel every lookd good the only off thing was that cilinder 1 made a noise like it was losing preusre the rest of the cylinders didnt make any noise also, were the rods conect to the crank i could move it just a lil in all four rods Are they supt to have any play ? ... what else should i look for ?? what should be my next step ?

 

Gold dust isn't a good thing. Probably your bearings starting to grind up. Needs a rebuild most likely

 

could this cause damage to thehead?? could a mechanic diagnose it just by looking under the the oil pan or do i need to tear all apart ?

 

im having the exact same problem withmy 2000 civic 4dr

 

does your knocking increase with rpm?

 

the nocking increses as the rpm increses yes

 

rod knock
