  1. I'm not sure if I understand what torque-to-yield means. If someone wants to explain it to me, I wouldn't mind.

     

    I've twice reused head bolts on the 2.5 without problems as of 10K miles. I didn't see anything in the FSM that said not to reuse them, so I reused them.

    The "yeild" on a bolt means that you are stretching it beyond the point of elasticity. Once it has done this, it will never return to its original length. This presents to problems for re-using these bolts. The first is necking down of the bolt where stretching results in a narrowing of the bolt stem which results in weakness. Think of a piece of pulled taffy to picture this. The second issue is work hardening. Think of how you pull a tab off of a beer can or pop can - you repeatedly bend it back and forth until it snaps off. The repeated bending has hardened the stressed metal and made it brittle which resulted in it breaking off. The same thing happens to the bolt when you re-use it, it becomes harder and more brittle and is more prone to suffer catistrophic failure.

     

    If you are so inclined, here is an excellent article on engine fasteners;

  2. McQuire's and a couple of others make a plastic cleaner/polisher that works fairly well. I've found that rubbing compound works like a charm at removing oxidation and polishing the plastic. I use 3M's fine grit and apply it twice. The first is dry, just like you would on paint. The second is with a water soaked towel. Then apply a clearcoat prep to the lenses and buff. Do this two or three times a year to keep your lenses clear and prevent oxidative damage to the plastic.

  3. A friend of mine recently bought a '98 OBW with the 2.5. I'm doing some work on it to make sure that she has a reliable vehicle. But I have not been able to track down the this hesitation and stumble on acceleration from a stop. What its doing is that if you get on the gas fairly quickly it acts like it loads up, stumbles and chugs, and then catches after a second or two. I've cleaned the throtle body and the TPS, replaced the fuel filter, which was nearly clogged, and the air filter. I've checked for vacuum leaks and bad hoses and plan on running some injector cleaner through it tonight. Oh, and it isn't throwing any codes so I'm hoping that someone here can give me some ideas of what else I might want to check out to correct this. I'd prefer not to have to take it to a sub mechanic because she is a single mom and money is a little tight for her, so any help that can be offered will be greatly appreciated.

  4. It's a bit of a distance, but there are about a million of them in Colorado. The nice thing is that they won't be all rusted because we don't use salt on the highways out here.

     

    Last week I went to Daytona Beach, FL, and was surprised at how few Subarus I saw once I got outside the Rocky Mountain region.

     

    Yup!

  5. Hello all............

     

    Have a 98 impreza OBS ......ABS light just came on.......and stays on

     

    I did do some rocking in my driveway last night in heavy snow (12")

    for a few minutes to get unstuck..........any thoughts if this is related

    and what i do next? Thanks for all input !

     

    Chances are that it just snow packed around the sensor as has already been pointed out. However, when you turn the car off do you hear a buzzing sound from the engine bay?

  6. By the MAP sensor, do you mean the MAF that is near the air filter? Does the coolant temp sensor also control the temp guage? That works normally. Hey Josh, could you post some pics of where these sensors are? Thanks.

     

    Yes I do mean the MAF, my bad. And I do not believe the the coolant temp sensor drives the guage. When it went out on my '92 it had the same symptoms as you describe but the guage worked fine. One difference is that when it happened to me it threw an occassional CEL

  7. I don't know Linda, that's a tough one. I too hate making car payments but Sub's can go for a lot of miles. My '92 has 157,000 on it and I plan to use it as my commuter for several more years. But then I'm fairly handy with a wrench AND I have three Jeeps that I can use if I have to fix the sube. Now you have indicated that you are a widow, do you have kids? How often do you break down where you are without transportation for a day or more? Ask yourself the question "Is it going to cost me more to buy a new car or keep this one running?" and include your time in that, after all, a few hours at the mechanics is time you've lost doing something else. But also consider the types of probs you're having. Does it break down or does it have problems that allow you to still drive it without compromising safety? Also consider that a woman needs reliable transportation because you don't need to be stuck on the side of the road at night, or any time for that matter. So given that I would suggest that you visit your mechanic and ask how much is it going to cost to make sure that your car is reliable? And ask them if they think that you can realistically get a few more years out of the car. Given that you say you do routine maint. I would tend to think that you could. Then weigh that against your finances. And I'll go back to my principle concern - and that is making sure that you don't find yourself in a jeopardized position.

     

    Like I said, it's a tough choice and neither I nor any one here can make it for you. But the bottom line is in weighing the costs of keeping it vs. the cost of getting another car. And when you consider this don't just think about the actual cost but also add in the costs of your time and the potential risk to you and your family should you be stranded.

  8. Who are the Mad Scientists in the group? What is in this SeaFoam stuff that it works like it does? I am always a little skeptical of additives but after reading several posts (and from people I trust who wouldn't screw up their cars) about the stuff I gave it a whirl. I followed the directions and ran it through the PCV hose. I put the rest of the can in a full tank of gas. Just like people said, engine smoothed right out. So what is it? The link is for their MSDS.

    It doesn't look much different than some of the other stuff but works wonders!

     

    Curious but pleased,

    For all intents and purposes it is a collection of solvents with some lubricity. The naptha is a collection of compounds from distilling coal tar. The IPA is a pretty good polar solvent and probably also serves as a wetting agent. The Pale Oil is proprietary and from the MSDS characteristics is probably a blend of light to medium fraction petrolium distillates which may include some aromatic amines. I may have to do a GC/MS and an HPLC/MS work-up on the stuff when I get a chance just to get a better idea.
