timing belt broke
well i had a very bad night at the track. my timing belt broke at over 8 grand duing the burnout! i just wasnt paying attention. im not sure if i realy hurt anythng though. the car is still at the track. i just couldnt believe i did that. does anyone know what kind of damage i could have done? it wasnt locked up,so it didnt sieze on me. i feel so bad about it. like i hurt my friend or somthing.( i know its just a car) i wont be able to open it up for six months. so that isnt going to be fun.

Re: timing belt broke
besides the negative effects of revving your engine past the redline, you didn't do any damage by breaking the timing belt. Our engines are non-interferance

Re: timing belt broke
Man I feel your pain, sorry to hear what happened. I kinda felt the same way when I blew my 1.8 engine. Diddn't have the car for 3 months.
But like GroHarlem said, everything should be fine. You just need to put in the new timing belt, maybe the tensioner too, and check the marks.

Re: timing belt broke
well ill be half the world away so it would be hard to get in the engine in less than 12 hours, with all the packing i have to do. well while im over ther im going to get a set of ze heads, and a ms8 im. oh well, at least i wont have to fight the timing belt off. i just got back from picking it up. i want to say thanks to everyone on this board that helped me. my car was running good before it broke.

You got exactly what you deserved. That big red zone is there for a reason .

Re: timing belt broke
What about your rev limiter? Doesn’t that go off when you were at 8000? I have once been in the high rev when the tires lost grip it hit 8 and bounced back.
More to the point you could bend a valve if your cam had a valve stuck in the full open position when the piston hit TDC. If that did happen the valve could have broken and parts would have scratched up the combustion chamber. Similar thing happened to my dad's drag camaro and we ended up replacing the engine.
If no damage was done getting the timing covers off is a real ***** because you have to take off every pulley and the power steering pump to get at it. It’s next to impossible to remove with out breaking the part that tucks under the crank pulley with out taking the pulley off and you need to remove the engine to get the puller in there.
Yeah I know you didn’t want to hear that but on the plus side if your like me and feel that part is not needed you can cut just behind the pulley and break off the non-needed part and it comes out easily.
Well good luck I hope you didn’t do any major damage.
By the way I hate it when people say people deserve what they got in situations like this. You can break your timing belt at any rpm and it obviously had some cracks in it cause 8000 isnt really all that high of revs.

The point made above was that the K series V-6's are non-interference engines....which means we couldn't bend our vavles on our pistons if we tried to.

Re: timing belt broke
well i made it to japan. today is my first day here. well about the rev limiter. i think that would have been bypassed when i put my MSD ignition in (6a box and 3055 mod). i just wsnt paying attention in the right places. i know, i felt like an idiot when it happened. but i cant change the past. i have seen 2 mx-3's in the first 8 hours of being here. they wer identical to ours besides the steering whel on the wrong side. i hope to make it to a junk yard this weekend.

Re: timing belt broke
Does the k8 even have a rev limiter? I didn't think they did

Re: timing belt broke
All Mazdas have rev limiters.
The rev limit on the MX-3 V6 is 7200 IIRC which would read almost 8000 on the tach because the MX-3 tach isn't linear.
It *might* be possible to bend a valve at high RPMS, but it isn't likely.
Installing an MSD does NOT bybass the rev limiter - you are still using the stock ignition pulse to trigger the MSD.

Re: timing belt broke
the skylines are every where around here. i have seen dozens of them. i even saw a couple rx-7s and supra's. there are some cars i cant even identify as well as super tiny cars too. like the mitisubishi guppy and some strange looking mini vans.
where would the rev limiter kick in at? i know the tach was pegged & i didnt hear it go off. what about the 3055 transistor? i dont know a whole lot about the electrical side of things. oh well i cant change the past anyway. i am in the military, that is why i am in japan. i hope the let me get my license here. if any one wants me to look for parts for them when i get off base i will try to. just email me. i know i want a set of heads
