had the intake gaskets changed drove it app 400 miles-no warning-it sounded like it through a rod-or lost its timing chain.it will try to start,but acts like its not in time-and bogs down quick,probably killed some valves also-is it worth paying money to fix?-or is it too much for a car that has over 200.000.car ran great,best car i ever owned.great on gas too,so plz give fair honest answers///

You would need to find out what the problem(s) is/are before making the decision as to whether to repair or not; it may be better and less expensive to have a rebuilt engine installed
99 chevy lumina-timing chain issues?
if a rod change the car. if not you can fix it.
you might get lucky and didnt hurt any valves. check with a good mechanic and see if the timing/belt jumped.
It all depends on you. How much to you like this car? How long do you want to keep it if it runs? How much is it worth to YOU?
If the chain broke, there is a possibility that some valve got bent in the process. If so, you could be looking at $1500.00 to do the heads and replace the timing chain. If you are a DIYer you could probably do it for half that.
Your best bet would be to call around to local shops, tell them what happened and ask for estimates.
Hope this helps and good luck.
I'm going to guess that the camshaft jumped a few teeth on the timing chain. You might have bent few valves. If so, it probably isn't worth the money to fix. Sorry
If you had coolant enter the oil system from the intake gasket failure, it is possible that the cam bearings were damaged leading to a broken camshaft. Depending on where the cam broke, would determine how many cylinders you have that still run. If you lost oil pressure when the failure occurred, that reinforces the broken cam idea, since the oil pump is driven from the aft end of the cam. The 3100's were known for intake failures and resulting broken cams seemed more common than thain problems. Certainly, I would not rule out a chain. I might consider removing the forward valve cover and observing the operation of all the valves, especially the aft valves.
If the cam is broken, the engine needs to come out of the car and repairs would likely exceed the value of the car.
