"Last thing: when you turn it off, there is a gurgle from the heater core. Air in the system, sounds like. But from where? It wasn't there before. Telltale head gasket failure?" Sad to say, the air in the cooling system, is the classic symptom of a bad HG. The "air" is actually exhaust gas escaping into the cooling system from combustion chambers through the bad HG. It is that hot air that causes the engine to over heat, while at the same time, impeding the flow of water/antifreeze through the heater core, causing the heater to blow cold air. When this is happening, you will prolly see air bubbles in the radiator over flow container. The air bubbles is/are the exhaust gas escaping from the cooling system.

If you bought the car at a Subaru dealership, you may want to ask the service department if they did the maintenance on the car. Talk to the service manager, with VIN # in hand, ask them if they can find the car in their computer. If so, they may tell you the name of the previous owner. I did that when I purchased my 99 used. I talked with previous owner to learn what maintenance had been done. If you can't learn anything, then assume the belt was never changed, and have it done, along with pulleys. Prolly a good idea to pull the cover to see if the timing belt looks old, and has cracks. I wouldn't be surprised if the spark plugs and plug wires are the originals, and prolly need replaced. Old plugs may be the cause as to why motor runs rough on start up.

I love Discount Tire, they do excellent work I have found. Spin balance is exactly that. The tire/wheel is spun at fairly high speed. Sensors pick up info out of balance situation, that will show the tech guy where to add a lead weight(s) to the wheel to regain balance. So by definition, it is more of a wheel balance then a tire balance. If in deed you have a tire with a broken belt, the tech guy doing the balancing, should be able to see tire wobble as the tire spins. Next time at Discount Tire, ask if you can watch a wheel being balanced. They will prolly let you back in the shop to watch it being done.

When weather warms up, you may want to see how much brake pad remains on your front brakes. When pads wear down, the caliper piston is further extended, so additional brake fluid takes up the former caliper space. This is what causes brake fluid level to go down in the reservoir, unless of course, their is a fluid leak somewhere in the system.

Yes, I think a tire could balance good, even with a bad belt. A bad belt certainly could cause the vibration that you have described. I am thinking a new set of tires will solve your problem. Prolly, still recommend a 4 wheel alignment even if you are not getting a "pull." My guess is that it has been a long time, and a lot of miles since you have had a wheel alignment. Once done, you will know that your tires are running good and straight, and true, and that you will be getting your best tire wear in the future. I keep my tires pumped up, and check them once a month making sure that all four tires are pumped to 35 psi on my OBW. I have one of those cheap 12v cig lighter powered air pumps. It does a good job of pumping up my tires on the driveway.

I am thinking you may need a 4 wheel alignment, because out of alignment can cause abnormal tire wear, even while the tire is still balanced. Does your car steering "pull" to one side or the other while driving? If so, that is one sign of a bad wheel alignment. Since you are down to the tire wear bars, you prolly need to buy a new set of tires. I know.........not what you want to hear with 35K miles on 80K mile rated tires.

I am guessing that the ATF level is full in the P/S reservoir. Front what I have read, Subie racks don't often break, so I assume it is prolly your P/S pump, if your steering wheel is hard to turn. If so, it is an easy swap to replace. Several years back, I swapped in one on my 91 Subie. It was an easy job. Got one from a wrecking yard that worked just fine. Cost was about $35 from the yard.

I bought a knock sensor from Autozone last summer. Cost about $75, so I have to think that most parts stores can get you one. It takes a wobbler on the end of a 3/8" drive to get to the awkward bolt that hold it in place on the block. It is a pretty ez job to do yourself, but it takes some patience to swap out. Just don't tighten new unit very tight, or you will break the plastic collar around the fastening bolt.

Yes, that's what happens when you start doing internal repairs on an engine. One fix leads to another, then to another fix, and then to another fix, and the next thing you know, you have spent a lot of time and money rebuilding the motor. I agree with your thinking, that buying a rebuilt long block, or a used good running engine is a good practical solution.

By any chance have you filled up your gas tank just before the problem started? My brother once bought a bad tank of gas, that was contaminated with water. Has it rained hard lately where you live? His car would idle and rev fine when stopped, but would stumble and stall under load. He added "dry gas" additive to his next several tanks of gas to fix the problem.

From what you described, it doesn't sound like you have a trany problem. I can't imagine that there was enough water remaining from the wash down to create white-ish smoke or steam. Suspect you have an engine problem. Have you checked oil and radiator levels? Do they look normal? If it is problem caused by the wet engine, suggest starting the motor and letting it idle for 15 to 20 minutes to heat up the motor and evaporate any moisture. Stay near the running car, in case anything abnormal develops. Keep us posted on what's going on.
