My 6.1 retrofit thread
PARTS:
Sump - MIL31000,
Pick up - MIL18331
Dipstick and Tube - MIL 22064
Oil Pan bolts - MIL-85025
Oil Pick up support stud - 6506333-AA
Oil Stud Nut - # 6502756
Bearing Cap Bolt - 06506272AA
Its been well documented that you need to use the Milodon centre hump pan and pick up to perform this conversion, but whats not so well known is that you also have to use the Milodon dipstick and the Milodon pan bolts as well.
The factory pan bolts are too long, and the Milodon and other aftermarket pans has no provision for the factory dipstick.....but fortunately Ma Mopar left the dipstick boss right there in the pan rail for us to use!
So -
- Remove the factory pan
- Remove the gasket/splash tray
- Remove the factory pick up
- Remove the small bung in the aussie drivers side pan rail with a small punch. This hole is used to locate the Milodon dipstick
First - the #1 main stud and # 3 main cap bolt must be interchanged as the Milodon pick up requires the stud to be at #3.
Unfo - these are 15mm Torque To Yield bolts..and therefore must not be re-used or they'll snap on you.
(You''ll also need a very deep 15mm barrell socket to get over the stud.)
So purchase replacements and simply swap them around. The torque spec is 28nm + 90 degrees for the stud and the main cap bolt.
The pick up bolt and nut are also 28nm (21ftlbs)......BUT NO 90 Degrees!
Next - fit the replacement Milodon gasket/splash tray. This is easier to use than modifying a factory one.
The Milodon pan has a different bolt pattern and doesn't use the four larger pan bolts - so using their gasket makes things tidier and easier.
NOTE: I modifed the factory one for this mock up - but Ill be using the Milodon piece when it arrives.
NOTE - There are two extra small holes in the corner of the Milodon gasket to match the pan - the corresponding holes are in the block, but may well be filled with RTV as the factory uses RTV to seal four corners of the gasket.
See pics below:
Extra holes
Gasket /splash tray fitted - note the unused larger bolt holes in the factory gasket at top right of the pic - the Milodon gasket doesn't have these.
Three - we fit the Milodon pick up - AFTER the gasket. Be extra careful with the bolt and the nut - dropping them will result in a major search and rescue exercise within the engine LOL!!:oops:.
Last! - we fit the pan! - the bolt tightening sequence is as for any other pan - start in the middle and work outwards.
I'll deal with the oil filter adapter modification and the dipstick in a later post!
PART ALERT
- You MUST replace the main cap #3 bolt and #1 stud - try to re-use the existing ones and they'll most likely snap.
- You MUST use Milodon pan bolts - the factory ones are too long
- You MUST use the MIlodon pick up
- Its BETTER to use the Milodon splashtray/gasket than to modify the factory piece
- You MUST re-apply RTV in the four locations as per the factory gasket - This seals the small detentes between te timing cover gasket and the pan rail - much like a LA engine.
