In short Andrew, only about 2-3 hours taking your time and cleaning as you go. Pretty easy.
M54 OFHG Replacement
- Remove center air intake housing
- Remove air filter housing complete with MAF and upper intake hose
- Remove engine fan with viscous clutch assembly with fan housing together
- Disconnect power to the alternator at the front charging/jump lug (thanks for the tip Andrew)
- Remove serpentine belt
- Loosen oil filter cap to drain oil from housing back into the engine
- Remove lower plastic splash shield
- Remove alternator and upper serpentine belt idler pulley
- Remove power steering pump (2 bolts in front, 1 in rear from bottom)
- Disconnect wiring connections from oil pressure and oil temperature sensors
- Disconnect the vanos supply hose from vanos
- Remove 6 bolts holding the OFH to the engine (use a box lid to place the different length M8 bolts so you know where they came out)
- Remove the OFH (serpentine belt tensioner comes off with it)
- Clean and inspect seal and groove
- Replace OFHG, oil pressure and oil temperature sensors, and vanos hose (not required but advised while it is apart)
- Clean engine waffle area
- Reassemble in reverse order
All in all it took about 2 hours to have everything back in place running and another hour checking for leaks, reinstalling the lower splash shield and cleaning and putting away the tools
