- Check coolant level in radiator cold engine, then oil in warm engine.
- Then press on and move around, the PCV valve. Pressing PCV valve into rubber grommet (98-02). Over time the rubber grommet, hardens and shrinks. Air passing, can make sounds, so can a fouled PCV valve. Check for other vacuum leaks, while at it.
- Make sure AC off. Helps eliminate AC compressor
- Then remove fan belt.
If above all good. Start engine while fan belt off. You can run engine for a few minutes, with Fan Belt off. Water pump and timing belt pulleys, will be running/spinning. If sound still present, needs a proper Timing belt service.
