Would swapping the the main bearing bolt / stud that supports the oil pump pick-up tube have any detrimental effects? After having done so and starting up the engine, there seems to be a slight grinding noise from the block @ the front end of a 2.5L.
Though runs fine and the noise seems to be subsiding after 4 days. The engines under a 3 year warranty, and I'm thinking I can wait till the first oil change to check for excessive metal particles.
2000 2.5L 2WD with 4 day old rebuilt engine.
