Depends on how many miles on it. Over 150,000 it'd be easy to say do everything (it'll then be good for 350,000), under 50,000 it's easy to say don't do any of it, in-between it's a judgement-call. The dealer used red silicone to seal my timing cover (PO hit a stump and it needed a new oil pan). Dave

Is it realistic that overfilling a 6qt motor by 1 qt would cause a loss of oil pressure? Even if it foamed a bit... Now, maybe some weird case of hydrolock caused by oil entering the cylinders after shutdown? There was a problem on the '01s where some chain guides would fracture, would cause a bit of noise because the chain would be very loose, but the engine would still run. Dave

I usually poke fun at reviving long-lost threads, but the tech articles are worth the bump! http://www.stoptech.com/tech_info/tech_white_papers.shtml I had severe 'uneven pad material deposition', and have discussed it here, but now I know the proper phrase! "Regardless of pad composition, if both disc and pad are not properly broken in, material transfer between the two materials can take place in a random fashion - resulting is uneven deposits and vibration under braking. Similarly, even if the brakes are properly broken, if, when they are very hot or following a single long stop from high speed, the brakes are kept applied after the vehicle comes to a complete stop it is possible to leave a telltale deposit behind that looks like the outline of a pad. This kind of deposit is called pad imprinting and looks like the pad was inked for printing like a stamp and then set on the disc face. It is possible to see the perfect outline of the pad on the disc. (FIGURE 5) It gets worse. Cast iron is an alloy of iron and silicon in solution interspersed with particles of carbon. At elevated temperatures, inclusions of carbides begin to form in the matrix. In the case of the brake disk, any uneven deposits - standing proud of the disc surface - become hotter than the surrounding metal. Every time that the leading edge of one of the deposits rotates into contact with the pad, the local temperature increases. When this local temperature reaches around 1200 or 1300 degrees F. the cast iron under the deposit begins to transform into cementite (an iron carbide in which three atoms of iron combine with one atom of carbon). Cementite is very hard, very abrasive and is a poor heat sink. If severe use continues the system will enter a self-defeating spiral - the amount and depth of the cementite increases with increasing temperature and so does the brake roughness. Drat!" What's more, later it describes how the cementite forms sub-surface, and cannot be removed by turning the rotor. Dave

Every time I run across an H-6 serp belt tensioner/pulley thread, I chime in with: - The H6 pulley bearings fail a bit earlier than the H4 ones do (seems that way to me, anyway) - The bearings in the pulleys can be inexpensively replaced. I have an '03 H6 with 115Kmiles, and figure I need to replace the bearings pretty soon. Dave

Maybe it would help to clamp the slave cylinder into its rest position, or collapsed as far as possible, then bleed? Whenever you pump the pedal, the slave pistion moves (even if just a little), perhaps moving the air away from the bleeder. Driving the car makes sense- the bubbles are like those stuck to the inside of a glass of soda, shake the glass and the bubbles dislodge. So, whack the MC and lines and slave cyl with a mallet a few times during the process. Dave

Is this the front, or the rear (rears being the subject of an endwrench article)? The knuckle could be out-of-round, front or rear. Also, was the shop familiar with subaru stuff? There are a time or two in the presswork where you have to be *very* sure you are supporting the right part. Lastly, did you torque the hub nut with the wheel in the air, or (hopefully not) on the ground? That's all I got, in addition to wjhat's been said above. Dave

The drain, even with lots left on, would be small compared to the starter current. If it were to make a difference for that start, or to the batteries life, the battery would already be so far down the path to needing replacement that it's going to fail soon in any case. I wonder if applying a smaller current before the big current might actually be good for a lead-acid battery? There's some interesting chemistry that goes on in those things. Dave

Todays 'don't do this but it's safe': I had a 1983 yamaha Seca 900 (XJ900RK) and there was a chunk of gas tank space that was not usable because a collar extended down into the tank, with a very small bleed-hole at the top of the collar. If you filled up beyond the bottom of the collar, you had to drip the gas in because the bleed hole was so small. I decided to drill the bleed hole larger, so of course the question is- 1) remove tank and purge of fumes 2) do it on the bike, tank with only a little gas in it 3) do it on the bike, filled up all the way I'm too lazy to take the tank off the bike, so obviously I did (3).

Heated Seats
CNY_Dave replied to nipper's topic in 1990 to Present Legacy, Impreza, Outback, Forester, Baja, WRX&WrxSTI, SVX
My drivers side heater in my '03 is at that point where it works, but is slow to heat up, and only works when I'm sitting in it. If it's not worse than last year I'll live with it, if it starts getting worse I'll be really interested to hear how this works out. Dave
