S54 Drilled Oil Pump Disc

Our modified oil pump is a stock oil pump disc that has been machined with a set of smaller diameter holes to eliminate the play between the disc and the exhaust hub, which helps to reduce exhaust hub failures.

We sell these on a core exchange basis with a $150 refundable core deposit. Once you return your old disc we will refund the $150 core deposit to you.

Optionally you can send us your oil pump disc for the modification, avoiding the core deposit. We can generally turn these around in 1 business day. See our Repair Work page for more details.
