Catostrophic timing belt failure

Hello everyone, so my timing belt tensioner failed on my 1998 prelude base. The timing belt and balancer belt broke and wrapped around the crankshaft breaking some teeth on timing belt drive gear. Its pretty insane, it took out both the tdc and ckp sensors and that bracket thing. My question is, is that area just the whole oil pump and can I replace that?? I put up a picture on here give me your opinions. engine has 80,000 miles so I want to fix it eventually, I have another car for the time being. let me know what you think

Re: Catostrophic timing belt failure

That's the least of your worries. Snapped timing belts usually result in smashing the valves against the pistons, aka a FULL rebuild is necessary.


Nice siggy BTW. What do you ride?

Re: Catostrophic timing belt failure

I already have the head off and dont see any damage on the top of the pistons or valves, i understand that i will not know for sure until i do leakdown but i have a spare head my friend has that ill use just to make sure. I can always fix the head i have now, maybe get it ported polished nd that stuff. So my question is wtf is a siggy haha and do the tdc and ckp sensors bolt to the oil pump housing???? And whats that bracket down there too becuase that got really messed up. Where can i get these parts???

Re: Catostrophic timing belt failure

I'm dumb; by siggy (signature), I meant avatar (your snowboarder pic next to your name). What do you ride?

I can't really tell from the pic cuz it's not enlargening, but I can tell you the CKP and TDC sensors bolt directly to the oil pump. In between the 2 sensors is a simple sheet metal spacer that keeps them apart, not sure if that's the "bracket" your talkin about.

You can get alotta OEM parts from here

Re: Catostrophic timing belt failure

If the sensors are GONE, they prolly damaged the threaded holes that mount them to the pump, so you'll prolly need a new pump. And to take the pump off, you first need to take off the pan, and balancer belt gears/housing. But if you're rebuilding the engine anyway, your gonna be disassembling everything regardless.
Nothing to worry about the timing belt/head when disassembling. Not til you get to reassembly.

Re: Catostrophic timing belt failure

I was told, and this is just hearsay, that the H22A1&4 are only interference while in Vtec. if you have a low RPM fail then chances are your pistons and valves will not crash. Can anyone verify this?

Re: Catostrophic timing belt failure

Happened to me a couple of years ago on my 5th gen....one of the bolts for the tensioner sheered off and got caught up in the timing belt and shredded it while I was doing 80mph on I-10. After a 140 mile tow, and a compression test...it turns out I bent half the valves in the motor... had just done the timing belt, auto tensioner, balancer belt, front seals, and water pump with a friend about 100 miles before the incident. could've been that we tightened the bolt too much, or whatever... end result was bent valves and a pretty good repair bill.
