I got my timing belt done on a 1999 Civic Si on September 26 @ 113,699 miles. at 116,9xx miles I bent a valve on my third cylinder. How likely is it that the timing belt is the reason why this happened? I heard that if the timing belt is a tooth or so off, it could bend a valve. So is it likely that this could have happened? Anyway to check?
A TDI has no valve to piston clearance as a results of the indisputable fact that's a diesel and has a extreme compression ratio. i'm a mechanic myself and hate to slam different techs yet it truly is clearly a screw-up on his section. There are some issues that would have exceeded off even if the shop he works at is to blame for the damages. If the tensioner did bend (which I surprisingly doubt exceeded off) then he has recourse by the business business enterprise that man made the tensioner yet to be quite truthful, it truly is only no longer real. similar is going for the snatch problem. that only isn't plausible. good success.
COMPRESSION TEST OR CHECK ALL TIMING MARKS TO SEE IF THEY ARE IN ORDER
If it was a timing belt issue it woudn't have only been one cylinder. And usually if it's only off by one tooth, it just runs poorly. IT has to be off by quite a bit, or the belt has to straight up break to bend a valve,, if that happened it would have made a horrible clanging noise repeatedly before it eventually sputtered out. the 1999 Si revs to what... 8000 rpms? You didn't happen to miss a shift and over-rev the engine, did you?
Yes, unless you've left out a critical detail (such as getting water into a cylinder), the timing belt is the most likely explanation for your bent valve. It doesn't neccessarily mean the person who 'did' your timing belt buggered it up, it may have just slipped. The short-ish period between getting work done and the valve getting bent is a little suspicious, but slips happen, especially with belts (as opposed to chains and dual row chains). This puts you in a difficult situation. You may also want to inspect your valvetrain, piston face, and the bore of that cylinder for damage.
