Help. previous owner runing it without oil.

[240sxlvr]

I bought a 91 240sx ka24de. but the owner said he was running it wihtout oil and one of the cams broke from the sprocket. and i plan on replacing the cam and adjusting the timing chain. What else could be wrong?

Running an engine without oil is probably one of the worst things you could do to it. So basically any moving parts that need sufficient lubrication could have gotten some pretty extreme wear; all engine bearings and piston rings come to mind. Also I've heard if your timing is off by to far on these engines you can end up bending valves through contact with the pistons.

The engine is probably junk at this point.
