OK, so I've been reading up on the posts on the board. I will try the flush first, but if the noise is still there, it seems it may be time to pull and replace the pump. So here is the rub - one of the indy's is telling me like $1350 in labor (like 12 hrs ?) with engine in car and like $150 ish if out of the car. My plan is to have it done a the next t-belt service. Seems with car in the service position, it should be fairly straight forward to get to the pump.
TIA
