Internal Interference Engine?

[nsx3000]

Does anyone know if my 99 Altima has an internal interference engine? Which means the valves will touch the piston when timing chain breaks.

Yes you have an interference design engine. Do you know of an engine that has a broken timing chain? If you do the cylinder head is probably warped from overheating and locked the cams. Timing chains will last more than 300K mi.
