2005 Acura TL Owner Comments

problem #4

TL 6-cyl

  • 129,000 miles


In the Acura 3.2 motors, the cylinders have oil release holes that are not smooth which is causing metal shavings to get stuck, shave and damage the cam shafts and cause motor failure. They are causing serious grooves on the outer 2 cam bearings that have the larger release holes. My motor failed due to this. I was driving, car stopped running, I thought my timing slipped. I pulled the motor apart and my cam was seized up after looking into it further. I order a new motor same year, make, model, thinking it was just my motor. I pulled the new motor apart and I found the same issue! the cam was getting scored due to the oil release hole not being smooth. I also realized that on the side that was not getting damaged it had an oil sylph, and which the side that was getting damaged did not.
