1999 Altima Timing Chain / interferance engine?

Is the engine in a 99 altima an interference engine? While driving the car it suddenly stopped running, upon inspection the lower timing chain is broken!

If this is an interefernce engine how much damage could possilby have been done? Would a compression / leak down test determine if any valves are bent? How tough of a job to replace the chain?

I realize this is very vague but I am looking for some answers to determine if I will go farthur on this car or not.

It is a 99 altima with 188,000 miles and has really been trouble free till this event happened.

Thanks

I'm working on a 98 altima with the same symptoms. I think this is an interferance motor and with no timing chain you could have damage to the head. I've read that the chains are pretty strong and usually don't break. I've got both chains but lost one of the main crank guides which alows alot of play. I did a compression test and could only get 50-55 pressure across the board. It's a major procedure to replace the chains and will run anywhere from $160 to $250 for a chain kit. I'm still trying to figure out if this chain issue is my problem, but haven't had a whole lot of help.
Good luck.

It is an interferance engine. You can get it fixed, you'll just need to get new valves in the head and make sure that the pistons don't have and major damage to them.
