Oldsmobile Repair Questions? Ask a Mechanic for Answers ASAP
The timing belt/chain on my 2002 4cylinder Alero broke. What would be the average price to repair this? The car was running very rough with bad acceleration the day or two before it went out and just would not start. Is it likely that additional damage has been done, valves, pistons, etc? Do you think the cost is worth repairing a 10 year old car with over 125,000 miles?

Hi, do you have the 2.4?
It's a 2.2 liter
These do have a chain, not a belt
What is a ball park cost, parts and labor to repair? What other damage might have been caused by chain breaking?
Well..most times, this won't cause other damage on this engine
Give me just a moment, I will get you the labor time and cost
My data bank is a little slow
It is an interference engine, but I have seen these come apart and not hurt anything. You will need to put it in time, then check the compression to ensure this
