the motor was rebuild last year do to a bad lifter It got all new pistons twenty Over, new rods and mains and the complete gasket kit. Put a new throttle body on it and most sensors were replaced. 167000 on body new motor was put in at 160,000. Dont wanna put anymore money into it. I believe the timing chain is going out. Little bit of noise coming from the front of the block. Call me with more details and I can get u a video of it running and what it sounds like.
