Thumbs down Blazer Knocks hard when starting and on shut down
a few days ago my blazer started knocking almost like a bearing knock when i start it up and shut it down... its not there at all when driving and i have noticed no loss of power or mileage... i was hoping it was not a bearing as i just put this motor in in march... thenon saturday i raced my buddies 360 Ram... which i beat BARELY!!! and noticed the knocking stopped it stopped for a day or so and is now back again on start up and shut down... oil pressure is good and i flush the system every oil change so the screen should be clean... also thought of pre-detenation... any ideas???
