New to the s2000 Have a rattle around 2-3k when warm? Thinking maybe timing chain tensioner … any advice highly appreciated

Das what it is mang.

I don’t know if the video is pinned here anymore but there is a repair for it but most people I know just replace it.

Remove, disassemble, clean and sandblast interior of piston (tape exterior to avoid damage), sandblast exterior of worm gear, get a 8mm bolt and thread through where oil bolt is, reassemble. Put in motor, bolt up, remove the 8mm and replace the oil bolt. Finishing buttoning it up. There’s a thread on S2Ki for it, sounds complex but it’s not, and you don’t need to remove airbox like they suggest. Just did it for the second time last week.

Just remove the tensioner off the side. Helped me to unplug the VTEC solenoid just to get that connector out of the way for the wrench. The first time I did it, was about 120k miles. Got 45k +/- out of just wiping off the worm gear. Sandblasting, we’ll see how far it gets. Beats buying a replacement, be it aftermarket or OEM.

Best to blast it to rough up the surfaces & increase the grip of the two parts. Check if your friends have one, otherwise hit up a body shop and see if they’d do it for you real quick. Takes maybe 5 minutes total, and it’s recommended to use 70-90 grit. Otherwise, yes, just wiping stuff clean will do for the time being
