KFJs "God's Chariot" e30
Sat down to warm up and finish cleaning the throttle body assembly. At some point, someone has already done this as the known leak points have been sealed. This is good. All I did was to clean it very well and make all the mating surfaces smooth.

I turned my attention to the TPS sensor. On the e30, it is mounted on the bottom of the TB. This can allow oil and grunge to seep into it and foul the electronics. Spec E30 racers drill a small hole in the TPS plastic case to allow any oil to drain out. I was also advised to change the O ring between the TB an TPS. Sure enough, mine was hard and brittle when I found it and pick it out of its seat. So, after drilling the hole, I shot some healthy shots of AFM cleaner in there and sat it aside to drain.

Tomorrow, I will go try to find a replacement O ring, some more cleaner for the engine, and install the last of the hoses. I will scrape and scotchbrite the mating surfaces for the IM, and change some tubing for the charcoal canister, and other odds and ends. It's a casual pace, which is nice. If I absolutely need the car on Monday, I would be scrambling, but I don't so... :)

Final item for tonight. I cleaned and prepped the oil down tube. It equalizes the pressure between the crankcase and the head. It connects to the bottom of the IM and the block. It is about an inch in diameter and 8-9 inches long an O ring on either end seals it and it is held in tension by a spring. It is also known as "the bitch tube" because it is a bitch to reinstall with the IM, mostly because of the spring. The trick is to compress the spring with thin wire or a thin zip tie, then cut it free after it is installed. Here's hoping this works when the time comes!
