This is the ECO-TECH motor correct? It will say this on the coil pack which is the black section on top of motor in the center of valve cover. The next question is did the chain break when engine running, if so this is a zero clearance motor and valves will hit the pistons and bend or break. I would go and purchase the repair manual, do to you will need to know were the timing marks need to be on the cam shafts
{Duel overhead cam} and the crankshaft. The problem is with the timing chain tensioner and a new updated one will come with timing chain when you buy the complete timing chain kit. There are three chain guides also { adjustable guide, upper guide, fixed guide }, i have see the fixed guide top bolt break and the fixed guide break also. I have done this on a Chevy Cavalier and a Saturn L series. This will take about a day if you are mechanically inclined, due to you have to take the front of the motor apart and work through the wheel will some. Then at the end you will have to fish a long screw driver down the timing chain, find the tensioner and pop the tensioner out of it's locked position before starting the engine. Buy the manual and read it before you decide to tackle this.
It seems to be hard to do.

Hi Angiebaby,
It seems the timming chain gave away!...you may have probabely been hearing it kinda grind before it snaped!
I am just guiding you the basics of going about it as am not fully conversant with 2001 olmobile alero, as we dont have Amercan Cars in our country, but the engines works in the same principles.
You have to identify as to how to get about to the timming chain inside the engine.
Do you have its workshop manual?
Well simply, all you have to do is to remove the crankshaft pulley, the water pump, the alternator needs to be losen to get the belt/belts out of the way and the alternator can be swang aside.
You will have to remove the top cover or the valve cover on the cylinder head, there you will thn come to the rokers and the tappets...check them for any damage to the valves as when the timming-chain snaped , the pistons in any one or two cylnders mayhve hit the valves thus bending them.
If all is well , all you have to do is remove the broken timming chain and its adjuster and guide...i.e. if the chain hasn't fallen into the sump.
If it has thn theres an additional job of pulling out the sump.
On replacing the timming chain its wise to check the sprokets or rather the timming geras both on the crankshaft and the camshaft for any wear!
its better you get an Overhaul gasket set too...just incase.
If the valves are damaged then you will have to bring down the cylinder head and replace the damaged valves and its guides and reaching to there you may as well do the top overhauls i.e. valve seat exming and valve lapping too.
GOOD -LUCK!
