Procedure for installing the oil pan brace

    1. Clean out oil pan stud holes completely, ensuring that there is NO sealant, dirt, etc. at base of holes. Failure to do so may result in cracking of plates. We recommend using a M6 x 1.0 Tap (pic #1) , but you may use a pick if necessary (pic #2).
    2. Remove any traces of oil with lacquer thinner or acetone and clean cloth. Ensure that the contact surface of all parts are clean.
    3. Using 3mm Allen wrench, thread studs into oil pan mounting holes (pic #3).
        • If you experience difficulty inserting the studs, please ensure that the holes are thoroughly clean and re-tap threads if stripped.
    4. Check oil pan for rim defects. If necessary, use pliers to straighten edges (pic #5).
    5. Place Banzai Racing Oil Pan Brace on oil pan (pic #6).
    6. Apply a 4 - 6mm continuous bead of RTV Silicone Gasket Maker to the bottom of the engine components along the inside of the studs and around bolt holes (pic #7). NOTE: Install oil pan within 5 minutes.
    7. Install oil pan and brace as pictured, lowering onto the studs (pic #8).
    8. Thread hex nuts onto oil pan studs (pic #10).
    9. Torque nuts gradually and evenly to 8.9 - 11 N-m {79 - 104 in-lbf} (pic #11).
    10. Using stock hardware (17mm bolts & washers), install right (passenger-side) engine bracket (pic #12).
    11. Torque engine mount bolts to 75 - 93 N-m (55 - 68 ft-lbf).
    12. Reinstall / reconnect the remaining parts in the reverse order of removal.
    13. Allow a minimum of 24 hours for RTV to cure.
    14. Add engine oil, start the engine and check for leaks and correct oil pressure.
    15. Turn the engine off and recheck the oil level with vehicle on level surface.

Note: Convertible owners may find it easier to remove the rear crossmember.
