  1. I agree with Setright - that consumption is not high. Some old V8s would use a quart in 900 miles and the manufacturer said it was normal!(of course - it's a V8) Still, before you panic, maybe a test (leak down test?) would tell you wheter it's the rings or just a valve guide/seal. One type repair may be cheaper/easier. or Try a heavier weight oil and just drive it.
  2. I don't see how the cam's actual rotation speed is affected quickly enough to alter valve DURATION during a fraction of a stroke. To me it DOES look as if the cam is being 'shifted' to begin it's opening of the valve at different degrees (based on several ECU parameters as outlined at that link) to positively affect performance. The i-Active thing MAY have an effect of increasing valve lift AND slightly increasing duration - but only because the 'pin' may allow the follwer to stay in contact with the lobe for a greater percentage of its profile - I'm less confi\dent about this - just a guess. I wonder if the 2 systems can be combined someday in one engine? Carl
  3. found this;>>>Overlapping the timing of the closing of the exhaust valves and the opening of the intake valves can help the engine perform better under heavy loads, but not under light loads. AVCS continuously varies this overlap through an infinite number of positions. Overlap ranges between a slight overlap (“retard” position) through as much as 35 degrees of the crankshaft rotation (“advance” position).<<< from here; http://www.drive.subaru.com/Win05_WhatsInside.htm and >>>More Power and Enhanced Automatic Transmission The naturally aspirated 2.5-liter boxer engine in Impreza 2.5 i and Outback Sport models gains the new i-Active Valve Lift system that boosts horsepower to 173 from 165 in the 2005 models. Just as important, the new technology improves real world drivability and performance. Peak torque output remains at 166 lb.-ft. at 4,400 rpm – still one of the highest torque ratings in the segment. Using oil pressure generated by engine speed and load, the i-Active system varies intake valve lift by locking the tappet into a higher position by means of a transverse pin. The effect is that of having two separate tappets to act on the camshaft lobe operating the intake valve. Variable lift works on one of the two intake valves. At low engine speeds the two valves open at different levels, causing a swirl of air and fuel and boosting torque. At higher speeds, both valves are opened in the “high” position to increase horsepower.<<< Carl
  4. There are 2 different systems. There is a dual lift system which does involve a pin being engaged. There is the variable valve system whic is in the cam sprockets. Now, is the variable valve system truly analog or is it simply switching from one timing to another? Intersting stuff carl
  5. wow! I just flashed on a term I haven't used in decades!; Oklahoma Credit Card ! lol!!! Carl
  6. Ran across a mention that the Baja is saved for '07 - if only I could remember where I saw that......... Carl
  7. Seems like you have noticed a change - and assuming it is 'more than subtle' I think a little experimentation may be called for. One thing to try is resetting the ECU. You maybe get Autozone or a friendly indie mech to do it for you, or tey disconnecting the neg batt terminal, pressing the brake pedal once or twice, waiting maybe 20-30 minutes. Recoonect and drive 'normally'. The car will 'relearn' it's map based on usage from that point. I do seem to recall a certain year or 2 where there was a 'reflash' for auto trannies too. Maybe someone recalls or you could check at www.my.subaru.com for recalls. It may have been a TSB. Soobs are fairly light cars so it's distinctly probable it is just trying to cope with the load. Seems weird it would be temperature related though. Carl
  8. I have decided to forego the RASB and may begin just with the front camber as you suggested. Cheap, easy to undo or alter. Ansd sensible I feel. A good fit for my intended use for this car - at leats initially. I seem to recal that there is some passive 4 wheel (rear wheel) steering built into these cars to help fight oversteer. I dunno where I saw that. If I get lighter wheels in the winter/early spring, I will wait to see what that feels like before doing any other suspension upgrades. I suspect, IF the stock wheels are 20-22 lbs. (a guess - still no definitive answer) and I can get some wheels in the 15-17 lb range it may have the effect of stiffer springs - not sure. thanx for replying Carl
  9. So, just exactly what happens during 'break in'? It certainly doesn't seem to be anything that affects the cylinder walls. What exactly happens the the rings when the rings are 'seated'? Carl
  10. If I throw increased rear camber into the mix, how does that affect your feeling on adding a slightly stiffer rear AS bar? That is, stock springs struts etc. Just increased front and rear camber(probably need camber bolts for the rear) keep the stock links but put in the RASB? Still too tail happy? Honestly, if I ever put springs on the car, I really do not want to slam it - 3/4 inch or so would be great. But, initially I wouldn't mind tweaking it the easy/cheap way. Though I think your wisdom about brake/oversteer is good, especially for a daily driver like this car. I always appreciate the insight from the regulars here like yourself. thanx Carl
  11. I have an '06 on order. I thought the engine has been out for a year or so in the Forester? I dunno. I'm excited and a little trepidatious - first turbo ever for me! Carl
  12. Maybe it's something as simple as some object under the lever not allowing it to fully retract? Or some carpet fuzz gumming it up somehow. Sounds like a simple problem but getting it resolved could involve some crazy disassembly! good luck Carl
  13. I recall threads in the past where folks used Hella 500s with an aftermarket bracket (Kartboy?) or fashioned their own bracket.. Try a search. if it wasn't here - try over at http://www.nasioc.com Carl
  14. I'll bet she's gonna enjoy it. I know my wife sometimes misses her van, moreso when the family is over cause we could haul 6-7 people. But every 2-3 weeks she mentions how she's had some comment from someone or a long conversation about the OBW - so I think she appreciates it as well. The van had her sitting higher off the ground and she misses that - but it was a beast to park - horrible turning radius. Ryan emails me with info, updates 5-6 times a week! He really takes care of his customers - I just wish they'd get my car in soon! Latest info indicates that Hurst and Arlington are both planning on staying open, and I guess Ryan is staying in Arlington - he was initially scheduled tomove to Hurst but things change I suppose. Carl
  15. everything I've ever read warns to avopid silicone based stuff for leather. not sure why. sorry, that's all I know Carl
  16. There's nothing magical about Subaru. They're cars and cars can have problems, be frustrating or even be lemons. I've a owned a fair variety of cars. I REALLY liked my Honda and my Datsun. Personnally, I feel my Subaru (soon to be plural as I have a WRX wagon on order from Ryan at Teape) is probably in the same range of economy/performance, style/practicality, safety/convenience and reliability. All autos have trade offs. Yeah, it's doubtful the AWD aspect of my cars will get much of a workout in D/FW, but if I need to visit my daughter in CoSpgs during the winter - I won't need to worry about traction. Actually, I'd likely buy a Soob even if it didn't have AWD. I'm a fan - that could change I suppose if I had experienced a Subaru lemon - but I haven't. And I guess the engineering/science 'fan' in me is impressed with Subaru's design approach. Go drive 2-3 models, pay attention to the seat feel, entry/exit and highway noise/performance - sounds like you'll be in the car a LOT. Carl
  17. Is the substance used by Mobil in that product available seperately? Would it be compatible with 'normal' oils? good review! Carl
  18. Some folks have a habit of depressing the accelerator pedal while cranking/starting. It has been mentioned that this habit can confuse the ECU as it is trying to record some kinda minimum TPS position. Try to confirm your foot is not pressing the gas pedal during starting and see if that makes any difference. just a guess - but HEY!, that's what you asked for! Carl
  19. I wonder if this engine was mistreated in the past. Seems like I have not read of valvesguide/seal problems here before. Not saying it can't happen or a single seal couldn't experience an out-of-the-ordinary failure - just seems like a rare complaint. Carl
  20. This is kinda curious. I wonder what color the smoke is? If it's black or blue - then I believe that couyld kill a cat. If it's white, could be a head gasket again (unlikely a coolant leak fix is gonna seal against compression pressures - good for external leaks only, usually). Valve guide/seal wear could maybe create the symptoms you have and not be found on a compression test. Wouldn't hurt to check the PCV valve and hoses too. I dunno. carl
  21. My wife's '03 H6 OBW has been great so far. The A/c is more than adequate for front seat passengers. Rear seat I dunno - I'm never back there. There is a cabin airfilter you will want to change probably yearly at least - more if you're in dusty dirty conditions I guess - to keep the air flow up through the system. I saw several used units at Teape Subaru off I20 in Arlington. I am in the process of ordering an Impreza wagon for myself. If you go to Teape, Ryan is the Soob maniac there. (ask to see his STi tattoo!) If you go to SOD, ask for Kevin. Of course, they may hand you off to a used car sales guy, I think they would at SOD anyway. good luck! Carl
  22. I'm not familiar with that exact kit - I assume it is a wiring kit? many Subaru owners have reported issues caused by poor grounding of sensors, relays, etc, due either to bad contact through paint or corrosion in extreme environments. I suspect most of any improvement those kits yield could be had by just going through you car as is and 'freshening up' all the ground connections you find. Take 'em loose, inspect the wire and connector. wire brush them to bare metal, reconnect them, maybe cover with some grease or other 'barrier' compound. Of course, if you've added some electronics or beefier stereo gear, that comes with its own electrical demand issues. The wiring kits also add a 'bling' factor from what I've seen that may make it worthwhile for some folks. You could dig around over at http://www.nasioc.com More tuner/modder type folks over there. Carl
