Rattle noise

Hey guys i have a 4th gen with h23a non vtec...

So my issue is i have a rattle in noise in the motor at any rev range but the once the clutch is engaged the noise will go even when holding the revs up... Ther is no problem with the clutch as i only just put it in along with machined fly wheel noise was ther prior. Any advice will be greatly appreiciated as i am stupped... i have slight feeling alond the lines of rod slap or bearing noise.


THANKS

Re: Rattle noise

ut oh. could be noisy valves and you just need a valve adjustment, or could be a spun bearing.

take a long metal anything (screwdriver, socket extension, etc...) put one end to your ear, and the other end touch various parts of the motor to see if you can pinpoint where the rattling is coming from (head, bottom end, tranny, etc..)

Re: Rattle noise

Put a screwdriver to it and heard a noise in the bottom end.. the valves need adjusting but its not that sort of noise. Do the h23a have history of spining bearings ??? if so are they hard to find and replace.
