There’s a few connectors left in the kit that are not installed, but the original factory ones still look like they’re in good shape, so I figure it’s best to leave them at this point. Which means I’m finally turning the corner on this maintenance “session” and actually putting parts back into the car. I rerouted the main harness and attached it to its keepers on the gearbox so it’ll remain clear of the shift linkages. I also took this opportunity to install the PTU and coil pack, since I remember how much of a pain those are once you have all the air and coolant lines in place on that side of the motor.
Before it got too crowded with bigger pipes and tubes, I also replaced the four vacuum lines that lead to the front turbo wastegate and all the EVAP equipment. I’m using some thick-wall, high-temp silicon tubing from Amazon. Hopefully it’ll last another 25+ years. I was actually surprised, all of the original tubing in this region was still nice and supple and without any apparent cracks.
I was able to get a good look and feel on the impeller of the forward turbo as well. Looks to be in real good shape. No oil, no shaft play at all, and no FOD hits on any of the blades.
To wrap things up in this corner of the engine bay, I attached the new connectors to the plugs on the PTU, coil pack, and coolant sensors in the fill tube body. Made sure all my blue rags were pulled from each air/coolant line, cleaned up the incoming lines, and brought in the upper and lower radiator lines, and the cross tube from the driver’s side intercooler.
That’s it for now. Pretty happy about bringing parts back in. Next is to setup the parts washer so I can get cleaning on the upper and lower intake manifold. I want to place the upper manifold with the throttle body into position so I can do a one-for-one replacement of all of those vacuum lines next. I won’t be installing it permanently at this point as I’m going to want to run the motor over a bit with all six plugs out so I can get the oil system primed up before the initial start. Will be a good time for a compression check as well.
