Fernando, you didn't say how your oil pressure was doing (especially at hot
idle). If your pressure is way down at hot idle, like under 20 psi, I would
guess your noise is worn rod bearings. The rod (and main) bearings can be
fairly easily changed with the engine still in the car (and in fact the
Haynes service manual suggests doing so every 30,000 miles as preventative
maintenance). Of course, check the journal diameters (either with a
micrometer or with Plasti-gage in the new bearings), if the journals are
worn undersize then the engine has to come out to have the crank ground.
If the oil pressure is OK (or changing the bearings doesn't help the noise),
then I would guess the noise is piston slap. New pistons and possibly
liners would be the cure.

To my way of thinking, if the engine has to come out, do a complete rebuild.
