Well, due to weather, I've been leaving the Laurel alone for awhile. I've done a few minor things, fixed the radiator hose that wanted to start leaking.
I started having my mileage drop drastically, it steadily dropped through the fill ups from around 20, to 17, 15, 14, 13. I was wondering WTF, but didn't have time to take a look into it, as there were no puddles of fuel or smell that gave any signs of a leak. But the last fill up (last week, 13mpg) I drove a short distance (within 20 mi.) and the fuel gauge was down to 1/2!? I checked everything under the car, and still no sign of a leak. But that night I drove it home, it was really cold out, and I could smell fuel pretty good. So as soon as I got home I looked under, and nothing. I looked under the hood, and the fuel feed line through the fender wall had residue around the rubber. So I checked it out, sure enough it was leaking a little. Looks like under full throttle it was spraying, but being in the engine bay and that I usually drive it when it was hot out, it would evaporate before leaving signs of a leak. That night was cold enough that I could smell it well and find it. So I just had to get a smaller fuel line clamp and that sorted it out.
Yesterday I helped a friend pull a L28 from his 280ZX to make room for an RB25DET that's on it's way. One thing I noticed was that his fan clutch was in really good shape (the one on my SR is a little worn out), and that it would fit, and even better that it had one more blade than mine. Since he was getting rid of his L28, he let me have the fan. Here's a pic of the two, the SR20's is on the left and the L28's on the right:
So today I fitted it, no problems. It protrudes from the engine very slightly less than the SR's did. I can see the temp runs just a little bit less, so it's getting more airflow. On a side note, I think this fan's balanced slightly better also, I don't feel quite as much vibration since I changed it.
