    HELP! engine making grinding noise

    i have a 04 sti...i really need some advice and help to see what is going on...well when my car is warming up i could hear a loud grinding noise coming from my engine as if it was a washing machine...as months went by it got louder and louder but once i start driving it it goes away like 5 or 10 mins after i start driving. the faster i go the noise goes faster. early during the year i had to replace my short block becuase i blew my rod bearings so im wondering is from that? maybe the guy didnt do the job right on my car? please help thanks in advance

    Check the two "external" belts (A/C and P/S-alt). Check for faulty external belt tensioners, as well as a faulty cam tensioner pulley.

    The external belts and tensioner pulleys are easiest to do. It involves removing the plastic top engine cosmetic cover, loosening the belts by loosening and moving the mounting brackets of the A/C compressor and alternator, removing the belts, and checking the compressor, the alternator, and the pulleys for binding or noise etc.

    The cam tensioner check involves removing the front cover that contains the timing belt. I won't bore you with the details but you start as above and keep going.

    It sounds like your best bet would be to take the car to a competent mechanic and have him/her diagnose it.
