motor noise

When I first crank up my 97 4.0 wrangler I am getting a sound like a diesel 30 seconds into cranking it up. It has 123000 on it. Any suggestions. If it needs to be rebuilt how much should I be looking to spend?

Do you mean it has a tapping noise that goes away after 30 seconds? Or does it make the noise all the time? How is the oil level & Oil Pressure? when did the noise start?

The rattling starts 30 secs after crank up. It gets quieter after you take off. It started the day after i bought it. I bought some gas from a mom & pop store so thats got me thinking I might have stopped up an injector (i hope). I changed the oil yesterday and added lucas and no change. The pressure is around 50

My problem started the same way..Then it got worse I changed the rod bearings and it did nothing..Might be a bent rod from sucking in water..When u changed your oil was there metal flakes in it??
