thrown timing belt on DSM

The belt usually doesn't rip teeth off unless there's something that is locking up.Most of the time on a dsm the teeth get ripped because something is causing way too much drag on the belt. Most cases it is the oil pump. They are notorious for having low oil pressure when the mileage gets high, mostly caused by owners not changing the oil every 2k miles like they are suppose to and becoming a hell of a drag on the system due to worn parts.
My suggestion is that if you own a dsm, and your belt broke, get a used engine.....this is coming from experience. get a used one, replace both the oil pump, water pump, and the belts along with all the seals, then reinstall into the motor. The thing will run top notch afterwards, if done properly that is.

I would just sell the car to me for cheap since the motor is probably f'ed and you probably don't want to deal with it!
that's funny troy, don't you have enough problems with your 2g? why would you want to deal with a 1g? -

2nd...Most used engines come with some kind of a warrenty, which is why I suggest replacing most of the critical things while it is out in the open. When the engine is removed from a vehicle and is in known working order, they usually check compression too, mainly because they dont want to send out a motor that may be running only on 3,5,7 cylinders.
3rd....This is from MY EXPERIENCE....both from owning a dsm and being a technician. They are a pain in the ass trying to fix when the valves have been bent....And there is always at LEAST 4 bent (intake and exhaust on 2 cylinders at once)
my .02 cents

owning a 1g = problems....
owning any mitsu with high miles = problemsGreat motors, horrible to work on.

i suppose neither one of us specified where the used engine would be coming from...
if the head is the only thing damaged, just send it off to buscur, ffwd connection, turbotrix, fasterthanyou, etc and get something better back
keep in mind, this is IF the head is the only thing damaged. i would take it to someplace that knows the engine before i even think about keeping it (for reasons that ryan mentioned) -
i wasnt mine but they fixed it it seems to be fine/

Owning anything making any power = problems
your stock honda = reliable.horrible to work on? haha....what do YOU work on?
what do "I" work on?? anything and everything. I'm not some punk who thinks he knows everything, I'm actually a trained and certified technician. Hell, I put motors in 2 different talons this past month because of timing belt failure.

wait so it just bends 1 of each in 2 cylinders?explaination....16 valve engine, 4 per cylinder, 2 intake and 2 exhaust per combustion chamber....
say cylinder 1 was on the intake stroke, so the 2 intake valves would bend, while the cylinder 4 was on the exhaust stroke, it would bend the 2 exhaust valves, but if it caught it among the floating part while all 4 were open on the intake stroke....called valve overlap....there is a chance it would bend all 4 of those, but very rarely. on a dsm, 1 and 4 are at tdc, while 2 and 3 are at tdc.

thats cool, we all get tired once in awhile

still waiting :rolleyes: ......unless you are asking
? if you are or someone wants to know, it is top dead center which is the very top the piston reaches in the cylinder

i was doing some research on cams a while back, so i know already, just wondering how long it would be until someone asked "what's tdc??"

I was just curious as to why you replaced the WHOLE motor in those 2 talons since they had timing belt failures? Were the bearings shot or have holes in the pistons or something?
ditto. depending on several factors of when the belt failed, i would expect that a piston or two might have been ruined, not to mention at least one other issue
