no on the sensor i wish the knock sensor did more its like the appendix its just there.the lostmotions would have been makein the noise the whole time he said after time it started where u located?

 

This SAME thing is happening in my EX. I had the motor rebuilt a few weeks back, and for the first 600-700 miles all was fine. Then one afternoon I started backing up and I could hear that thudding/knocking noise. ALMOST sounds like its in the valve case, and I can hear it mostly at about 2300 RPM's. It's a dull thudding like if you knocked on the valve cover really fast with your nuckle. Sound the same as yours?? From the center just above the headers. We checked the oil pan for shavings too... nothing. Checked everything we could think of. I have no codes either.... I had 3 bad motor mounts, and after replacing the upper driver's side the noise has subsided, but it's still there a little - I still have to replace the driver's side lower and I'm hoping that takes care of it. It could be a combination of things...but so far I haven't had any major trouble...please keep us updated as to what you find!

 

so basically if its a rod knock or if if the bearing is gona spin i should check my oil pan for shavings?

 

Definitely. If you've got a spun bearing you'll know.... it gets louder and louder and you'll have metal shavings in the oil. Make sure you check all through the bucket or whatever you use to drain the oil in to. The metal is going to settle in the bottom if there is any in there.

 

i jus change the oil the other day and have the bucket next to me, ill check it in a bit.

now how can i check if its a rod knock?

 

im locATED in Clearwater, by countryside mall im gonna do my oil change too and see if there is any shavings plus im gonna take the head out tomorrow

bump, any info?

 

we did the valve adjustment and re did the timming and its still tapping, it sounds like the valve is bend for over reving

 

when you drive there car, does it bogg or sputter a tad bit sometimes?

when its a normal operating tempeture, and you stop at a light, does your oil light pop on, and when it idles between 800-900 when it hits the 80 do you here a little click clack within the the tapping noise?
