Since I got the dash out I went ahead and lowered the heater/ac box down into the cabin to make room for installing the wiper assembly.
Got the wiper assembly installed, with new bushings as someone on the forum recommended. Went to install the blower fan and resistor and found out the blower resistor is the wrong style, 4 pin vs 3.
Started looking carefully at the rear accumulator pipe options, just thinking about what would be cleaner, easier to service, and just more reliable?
The accumulator pipes come in at least 3 configurations, one with 4 outlets and one with 2. The ones with 2 come with no threaded bongs for temp sensors and one with. I ended up collecting all 3 styles between the 3 engines I've gotten .
Obviously need to lines for the heater core...and one needed for the expansion tank. Running the expansion tank there are also two options. 740i water pumps have 3 coolant hoses, and 540i water pumps have only two.
So with 740i pump you have the 2 hoses going straight to the radiator and one hose for the expansion tank. With 540i pump you have just the two radiator hoses, so the expansion tank would need to be run off the back of the engine.
Obviously there are pros and cons to each configuration here, you want the line to be as clean or straight and expansion tank at the highest position so that's a given. I'll be running one by the firewall on the passenger side where I have most room. Running a coolant line to the front of the engine / water pump doesn't look as clean but it sure looks better from serviceability angle. The rear accumulator pipe area is REALLY tight/busy even with just 2 hoses going to the heater core pipes.
Need to basically make a decision in the next week or so and order the water pump so I can seal the coolant pipes under the intake manifold and rear pipe up.
Got a 95 m60b40 540i/6speed manual harness from a member on BFC. I didn't want to run an auto harness and have extra connectors dangling, so hopefully this one will work fine and keep things neat.
I've been exchanging some messages with DUDMD tuner on BFC as well regarding DME options, I want to ensure there is no off throttle lag/delay with rpm's sticking and also no ECU codes that would show up and cause me to fail BAR test.
This weekend I have the following on my TO DO list
Finish up the wiper motor assembly install (need one washer).
Finish installing the heater/blower fan plastic shrouds (what a major PITA that is).
Need to get the right 3 pin resistor fan, maybe I'll locate one tomorrow otherwise will need to come back to this again.
Pull the engine out, lock the flywheel in place with the m6x tools and torque the flywheel bolts
Install and torque the pressure plate and install the clutch.
Install x5 oil filter housing o-rings and torque the plate
Massage the firewall area by the heater core hard lines at the back of the engine
Massage the passenger footwell area to make room for the exhaust manifold.
Mount the wilwood bias prop valve
Run the hard lines to the valve, from the valve.
Next weekend bolt the engine and trans together and drop it in again as one unit with exhaust manifolds attached.
Hopefully get the coolant stuff figured out with regards to the rear accumulator pipe and heater hoses.
Install water pump pipes, water pump and intake manifold.
Install starter, alternator, pulleys, power steering pump.
Start on wiring.
