Knocking problem

[SpLaTTy]

hey got a question. I got a 1995 Z24 Cavalier with a 2.4L Quad 4 engine, A/T. I bought the car from my friend for $500. Car has exhaust system done, 16inch american racing wheels and cold air intake. (Pretty good deal i think lol) But it has a bad knocking problem. He said he was on the interstate and raced some civic down through it, said he had the gas all the way down and all a sudden the car just died lost all power. He said he pulled over and couldnt get it started, so called a tow truck they came and got it and towed it to there garage. They said the timing chain broke. So they put a new timing chain on it and new sparkplugs. Now when i go to start it up it knocks very loud. Dont know what the problem is, im kind of a noob on working on cars but my dad is real good, but hes to busy to look at it right now. Plz help!!

the timing needs adjusting thats all ecu reprograming or somthing with the timing chain nothing major. some times a bad egr can do it so block it off.

sounds like a spun bearing. junk the motor.... ive done it twice in my 2000 Z 2.4L call junk yards find a good one and drop it in.

I bought a 93 cavalier from a friend and the engine did the same thing. It turned out to be the connection rods, so it needed a new engine. i was using it for the transmission, so it didnt really bother me. =)

yep, either timing or he spun a rod.
