OK, it's been awhile since I've updated this, but suffice it to say, the car's running better even though it's leaking a little oil. OK - maybe a little more than just a little.
The eBay 'performance chip' upgrade that I ordered turned out to be a 3300 ohm resistor that you're supposed to plug into the IAT (Intake Air Temperature) sensor socket instead of the IAT itself. But Nope. The Check-Engine Light never went away, and there was nothing noteable with the performance.
One thing that I've done since all that was look into the Cold-Air Intake systems. Everybody raves about them, although I was less than enthusiastic. Rather than pay $180+ for a K&N kit, I found a display at O'Reilly Auto Parts for a modular CAI - a whole bunch of parts to build your own CAI. Since the throttle body was WAY smaller than anything the 'kit' offered, I left the stock air tube on (all the way to the factory air box). After grabbing a coupler, a 6" length of tube, and it's corresponding cone-style air filter. I removed the factory air box and installed the new parts, and the engine really seemed to wake up. Of course, if you hammer the throttle, you can hear the engine sucking in tons of air, but it actually moves along much quicker now.
Actual price: $49
Which brings us to the issue of the oil leak. I figured that since we hadn't cranked down the torque on the head bolts, that maybe between that and the gouge I put in the head gasket (albeit not in a critical location), might've caused the oil leak. As it turns out, 2 weekends ago, Jemezman and I pulled the head, swapped out the head gasket, and had it all back together in about 4 hours. Even with an hour or so of picking up some furniture from an estate sale his wife wanted mixed in there. Easy as pie to work on this car.
Unfortunately, it had zero impact on the oil leak, but I now have the peace of mind that the head gasket is pristine, as well as the head is torqued on properly. Now, we're looking at the oil filter adapter, and/or the oil pressure sending unit being the culprit, since the leakage has not subsided.
We also discovered that there's a distinct possibility that the PCV was not re-installed when I put it all back together the first time. We don't remember having to go through all the pain of hooking it back up from the last time, so it's a distinct possibility - that, and it's running like a champ right now. Between that, and the new home-made CAI, the little car's running awesome. Once I get the oil leak under control, I think I'll be in good shape.
All that's really left is to finish cleaning/waxing, get some seat covers, and dump a couple of subs and an amp in there to flesh out the stereo a little.
I did happen to see some really nice (cheap) rims at Pep Boys when I was in San Antonio this past week... and even though I know I'm not supposed to be thinking along these lines, I might see what happens if my position gets upgraded as has been promised. Or maybe even might make a nice Birthday present... you only turn 40 once, after all... and I guess this is as close to a mid-life crisis car as I'm going to get.
Here's what I'm thinking of:
