No. I'm beginning to suspect the fuel pressure regulator. I was checking (again) for loose/disconnected vacuum lines, and tapped on the FPR. Immediately after, it ran great, and then after a while, began running poorly again. The blatent smoking is much less, but still crops up for 10-15 seconds at a stoplight about 25% of the time.

176K miles. Before the rebuild, there was no coolant loss.

I wasn't losing any coolant that I could tell (before or now). Like I said, the heads have been rebuilt, so it's got all new headgaskets, new fluids, etc. Temperate range is normal, smack dab in the middle once it's up to operating temperature (which is when is seems to start smoking). The longer it takes to get up to operating temperature, the longer it takes before it starts smoking. Yes, I'm quite sure it's not black smoke. I've had that issue. It's not as white as coolant, but definitely on the lighter side of middle gray. I have smelled gas once, but the problem wasn't happening, and I didn't smell it today when I got out of the car. It also doesn't have that sweet smell that coolant smoke does. I'll check the vacuum hoses at lunch, though I gave them a look over when the problem started happening initially and couldn't see anything amiss.

I have a 92 ES300. Recently, it started with greyish white smoke. Occasionally, it would puff out a bit for a half-second at startup if the car had sat for more than a couple of days. However, it began acting differently. No smoke, ran great for about 5-10 minutes (depending on if it was surface streets or highway. Ran a little better longer on the highway). After a period of time, it would consistently smoke. It also was throwing the code for the left main bank 02 sensor. I knew that the car was burning a tiny bit of oil. About a quart every 3 months or so. So, I took it to an independent shop, and they wanted to do headgaskets, timing, rebuild the head....almost a complete rebuild. Finally got the vehicle back, and for the first day (I only drove it breifly around the neighborhood, and on the interstate for about a mile), it ran great. This morning, it started doing the same identical thing. Ran fine for a few minutes, and then started smoking exactly the way it was before. It's used 1/4 a tank of gas for about 40 miles of driving (it got poor mileage previously also). I realize that yes, I will need to take it back to the shop (which I am). I just want to go armed with information about what they need to be checking. Is this possibly a bad 02 sensor (a byproduct of burning a bit of oil all the time)? The CEL is no longer on, but I haven't tried to pull any codes yet to see if something is still present.

Good luck to me trying to trace it down.

Turns out the DOME fuse keeps blowing for some reason (and, electric locks, along with keyless entry) does not work. I wonder if they're possibly related.

I recently purchased a well-used, but well-cared for 1992 ES300. I noticed (when trying to check my gas mileage), that the trip odometers seem to reset every time I power the vehicle off. Also, the tachometer intermittantly works (the needle is completely dark, so I wasn't sure if they were related), and when it does, it rarely goes past 2500 or 3000 RPMS. Bad gauge cluster, or is there another issue that could be causing it? Is the memory for the trip odometers powered by a random fuse I'm missing? Thanks, Chris
