I have a 1998 Mercury Mystique LS 2.5. Rod let go in the no.3 cylinder at 65,000 miles. I replaced it with a used motor with 56,000. The root cause wasn't determined. I had no audible or visual indication that the water pump had failed or was going bad. Here's my vin# 1MEFM66L4WK638136.

Has anyone added an Accusump Oil accumulator?
Is it worth the $325.00?
