[urq] 1983-1985 differences

[Louis-Alain Richard]

I am currently working on Eric's car, a 1985 WX. The engine is still
experiencing a cut-out, now in the 3000 rpm range. My guess is a boost leak
somewhere. So last night, I replaced all the vacuum hoses, even the hard-to
reach one that goes trough the firewall to the ECU. I also re-soldered the
terminals to the air temperature sensor and cleaned the WOT/idle switches.


When poking in this area, I discovered a few disparities with my 1983. Can
anyone of you confirm, please ? It will help us determine if the car is
still in his stock form.

- on a 1985, there is crankcase ventilation steel tube that come out of the
bottom of the block. BTW, the block is a genuine WX, according to its block
number.

- the casting for the engine head is different; it has a mounting boss for
the 4000-style vacuum pump, even if this boss is not functional.

- the thermo-time switch is moved from the back of the head to the elbow
housing.

- the ECU tag is blue, where the 1983 is yellow.

- there is a bleeder screw on the top of the radiator.

- the radiator fan switch is the 2-speed unit in the bottom of the radiator,
where the 1983 has 2 different switches, one in the radiator, one in the
tank-to-radiator hose.

- the ignition module is still in the glovebox, but closer to the right side
of the car.

More to follow.
