not good thing timing belt break most of the time valves will get damaged you might be lucky my timing belt broke on my 1977 vega monza didnt damage valves but i had timing chain break on 98 lumina got valves damaged.
it is an interference engine which means that when a belt breaks , you can expect at least half of the valves to be bent and need replacing
you can get more quotes for the job as that seems extreme
the work entails replacing the belt , idler pulleys , cam and crank seals and hydraulic adjuster ( a professional job to get another 60,000miles from the belt)
That much will set you back by around $1000.00 including labour
The extra is the head removal and new valves so add another $700.00 --including labour )for that and you can see that you need more quotes from accredited service shops
if the timing belt has snapped, expect the cylinder head to need replacing as some of the valves will have hit the pistons (which may also need replacing but not always) and snapped, and they will almost certainly have damaged the cylinder head beyond repair. when you add the cost of the new belt, gaskets, seals and labour charges, even if there is no damage to the pistons and barrels, it may be more economical to find a replacement engine.
sorry to be the bearer of bad news, but timing belt failure is a major problem and does major damage.
Highly probable
A broken timing belt will result in the pistons hitting the valves this can either bend or break the valves causing damage to the head and possibly to the pistons as well.
No,the 1996 Mazda 626 is not a interfearance engine, meaning that the valves will not hit the pistons if the belt breaks while underway but the engine will not run untill the belt is replaced.
1.9L SOHC (SEFI on Valve Cover)engine, no, they are non-interferance engines, put a new timing belt on it and go.
1.8 DOHC engine, yes, it will destroy the valves, head, pistons, and if really bad, the block too. These engines are interferance engines, where the valves just barely miss the piston as it comes up, and when the belt breaks it will hit the valves and destroy the engine.
Best to go into a Mitsi dealer and take a photocopy of the timing belt replacement instructions. I would be very concerned that there may be internal engine damage if the cambelt has broken, such as bent valves or piston damage. It's highly unlikely that the cam will stop in the right position with all the valves almost closed when the belt breaks, but I have heard of it from time to time.
Hope this helps,
Mark.
these free wheel when belt breaks they dont bend valves
but you need to remove both rocker covers to align cam gear mark and have cam lobes in these positions
