Minor update.
I received the car back from the clutch job. The Exedy is heavier than expected but a massive improvement over the old slipping clutch. There was some seeping from the master and slave cylinders so replacements have been ordered.
The brown oily coolant was apparently just rust flushing out of the system, which the mechanic believes was caused by water (rather than coolant) sitting for a long period. It's bled and holding coolant so problem solved for now. All hoses are in less than average condition but there's so many there I don't know where to start replacing lol. There's no point doing one or two if they're all in a similar state. Silicon sets online only seam to have 7 or 9 pieces, where as the entire system has 20+. I might look at some diagrams and try to get as many as possible from lithia toyota. Thankfully I don't think I have a head problem which is a slight relief.
One unnerving discovery was the complete lack of front engine mount, which explains why the rear was so torn up!
I've now got a kirkosaurus insert in the rear, and the bracket and bolts for the front are on the way. Hopefully it will all bolt up and there's no hidden reason for it being removed in the first place.
The brakes are the next focus. The pads actually had heaps left but it's all looking a bit tired.
In the process of rebuilding and cleaning up the calipers now. One of the sliding pins was completely seized, and probably now bent after my removal efforts. I've ordered a replacement pin to use if and when I can get the old one out. Maybe I'll get the rears done professionally...
Cosmetic issues are mostly on hold whilst dealing with repairs. Whilst I'm waiting for more parts, I'm planning to have a go at touching up the bumpers and mirrors with a colour coded aerosol I got from supercheap. The mirrors are down to primer which isn't a good look. A complete re-spray will have to wait till next year.
