While searching for the pictures I posted above, I came across a thread in which a guy was asking for help dealing with some gremlins on a car he'd recently purchased.
I immediately recognized the under-hood shots. They were of my old '92.
Apparently, the guy I sold it to proceeded to royally **** it up, and then re-sold it to another poor bastard who couldn't figure any of it out.
It made me sad.
I did not apply the "JDM" sticker under the hood, nor did I cut the valve cover and paint the cam gears purple.
When I sold the car, it had a functioning windshield-washer bottle, which was also the primary reservoir for the now-gone water injection system. (It was refilled automatically from a larger tank in the trunk.)
When I sold the car, it had COPs. And proper ducting. And a heat shield over the turbo, which was made of two layers of steel with a layer of fiberglass heat-wrap material in between, all riveted together. And there weren't mystery wires dangling near the steering pump. And the vacuum line coming off the up-pipe (which feeds the MBC) was properly supported. And I have no idea what that white tie-wrap just behind the drivers side headlight lid is doing. And the side-mirrors weren't painted flat black. And I'd just installed a brand new dipstick with a non-broken handle.
This is kind of what I imagine the OP is dealing with right now.
