LT5 INTERNAL NOISE

[fred dosa]

CAN ENYONE TELL ME WHERE THE NOISE IS COMING FROM,
I KNOW ABOUT CHAIN RATTLE AT START UP THAT GOES AWAY AFTER 2 SECCONDS, MY NOISE STARTED LAST FALL INTERMINTANTLY AND DOES
NOT GO AWAY WHEN IT BUILDS OIL PRESSURE, I MUST SHUT ENGINE DOWN
AND WAIT 5 MINUTES AND RESTART. TO STOP THE NOISE I PUT ENGINE RESTORE IN LAST WEEK, SHOULD I HAVE DONE THAT?
SOMETIMES I MUST REPEAT START A NUMBER OF TIMES FOR NOISE TO GO AWAY. A COUPLE OF DAYS AGO I TOOK THE CAR FOR A RIDE ON THE HIGHWAY,
WHEN TO MY SURPRISE A PORCHE 911 WANTED TO RUN, I TOOK THE
MOTOR TO 7000 RPM AS I HAVE DONE HUNDREDS OF TIMES BEFORE
BUT THIS TIME THE MOTOR STARTED TO SOUND OUT OF TUNE
AND LOST A LOT OF POWER,I'M HEARING A LOT OF RATTLING NOISES
BUT OIL PRESSURE IS 30 LB AT IDLE AND 60 LB DRIVING
THIS MORNING I STARTED THE MOTOR HOPPING THE NOISE WAS GONE
TO MY SURPRISE I COULDN'T HERE THE NOISE, BUT WAIT IM STARTING TO HERE SOMETHING ITS GETTING LOUDER AS THE ENGINE WARMS UP
WHEN ITS WARM ITS AS LOUD AS BEFORE .
