Getting the factory thermostat location cleaned up for a block off plate
Measuring to drill for 2nd coolant hole at the rear of the head.
Treasure located, time to dig
Start with a little bit, there's not a ton of room for error. EGR passage on one side and valve dome wall on the other
and its gotta line up with the passage on the block
First small hole drilled
drilling second larger hole after confirming correct location
Done, yay!
Lines up nicely
Notice front of RWD head gasket has no coolant passage holes
The maddness behind this is, because I'm moving the thermostat housing to the front of the head I need to improve coolant flow through the rear so coolant doesnt sit there stagnant and steam. I accomplish this by closing off the ports in the front and opening them up in the rear of the head therby forcing the coolant to flow up through the back of the head from the block and to the front exiting via the newly located thermostat housing.
Moving into the head with the boroscope.
Shavings from drilling are on the floor of the coolant passage which is actually the celing as the head is upsidedown right now,
the big circular structure ahead with the casting line in it is the outer jacket of cylinder #4's valve dome.
Were on the inside of the coolant passage in the head looking through the hole I just drilled,
yes that is my eye ball pressed against the outside bottom of the head looking back inside.
Helping the epoxy paint on the moddified headlight bezels to dry
Stir in some moddified BMW 5 series projector buckets
With a nice press in fit.
Add some clean epoxy adhesive action
compared to old sealed beam
retro modern projectors!! and they retain factory aiming ability. I might give 'em halos, depends on how fast and furious I feel later.
rarrr!
