I purchased the Z1 34 row Setrab oil cooler kit in 2013 and discovered it has developed an internal leak. The attached photo shows (viewed through fascia) shows oil stains (dark area) vs normal area (top right).
I was really shocked it would fail this way rather than at fittings, as there is no impact damage, has had regular oil changes, usually before each track event, and only ~32K miles of which 3K are track miles. Just wondering if anyone else has seen this. I ordered a replacement from pitstopusa today for $330 saving the tax & shipping that Z1 charges.
