All in - pulling the 4.6 engine and trans to fix oil leaks once and for all

[kesslerbmw]

Sweet! Love the pile of parts on the table.

Got the valve train put back together. Here's a comparison of the old and new guides for the upper tensioners:



Tensioners re-assembled with new O-Rings



Torquing the 11mm nuts to 14 Nm



Next up was installing the new Vanos check valves (old one shown in this shot, but I got it swapped before putting the housing on)



Then the new sealing rings



New gaskets. number facing the front as seen here.



And finally the housings. 10 Nm on these 10mm bolts



Next the Vanos units, exhaust cam gears, upper chains, lower chain and guides. Unfortunately I somehow forgot to order the all plastic guide, so it will be a few days at least before I'll be able to button up the front.

So while I wait for the all plastic guide to get here, I figured I'd do the bottom oil pans and rear covers.

Upper oil pan gasket placed



Upper oil pan installed. All bolts torqued to 12 Nm. Oil pick up tube also installed and also torqued to 12 Nm.



Lower oil pan installed. These bolts are all 10 Nm (8.8 grade vs. 10.9)



Next up was replacing the axle seal on the front diff



Front diff installed as well as the extension on opposite side of the upper oil pan housing.



New RMS installed



Rear of block ready for gasket



Gasket installed and sealant also applied to rear cover



Cover installed and sealant applied to rear coolant cover



Gasket installed. It came with sealant already applied, so no need to additional sealant on the cover itself



Rear covers completed



Flywheel/flexplate mounted and 9 new bolts shown



Flywheel bolts torqued to 77 ft. lb. I have also installed the lock pin (red arrow)



New valley pan w/ "built-in" gasket



All torqued down (10 Nm).
