The theory is the same weather its one cylinder or multiple cylinders. I can steer you towards REALLY heavy engineering books if you want. The combustion porcess doesnt care if the engine is 10cc or has a displacement measured in cubic feet. Sorry (waving automotive engineering degree) the article is dead on. I posted it as I got tired of having to re hash it every time it came up. nipper

as much as i keep out of this debate, prefering to talk religon and politics, all i have to say is HAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA im not a big fan of switching to syn from dino oil after the car has many miles on it, but this is the silliest thing i ever heard. nipper PS even switching to synthetic you still need to change the oil filter at the recomended intervals.

please do. i actually replaced the speakers with OE (price was great) and i needed them. i'll wait for a report nipper -
It doesnt really help gas mileage. The same parts are moving no matter what. This is not like some 4wd trucks where the front hubs unlock. On those the unlocking of the hubs disconnect the wheels from the rotational mass of the driveline (which is big and heavy and robs power). You cant remove the rotational mass on a subaru. The engine has to work just as hard to drive that mass as when it is driven. nipper

a duty solenoid cycles on and off really fast to vary the torque split. the 90/50 split is varied by doing this. When the solenoid is fully off (failed) you get full awd drive at max internal pressure on the clutches. With the solenoid energized, all the pressure is dumped and you get no rear wheel drive. By pulsing the solenoid it doesnt really get hot, and it constantly varies the amount of power to the rear wheels. nipper

cookie you live in SF and you drive a stick? i am impressed. i know its aprils fools right? Duty C solenoid is duty solenoid. The differnce between a duty dolenoid and a solenoid is that a duty solenoid is not desighned to deal with high heat. A regular solenoid can. The duty solenoids in the tranies are blessed in a way. They are in an area where heat is taken away from the, and a cool fluid runs through them. Theri survival depends upon the temperiture. If your driving on blacktop in Az in rush hour you may make it angry, or august in rush hour. nipper

do a search on head gasket ballpark 1200-1500. At the same time have the water pump replaced, timing belt, cam seals, main seal, reseal oil pump, and check replace the tensioner and idlers Youll be good for 100,000 on those and for 200 on the HG or more. nipper -
i've never seen anyone say an engine is not rebuildable, and i'm an automotive engineer, so i would notice these things. Also there have been more then a few engines here that have been rebuilt at dealers, or torn down so far (ie pistons) that its very close to a rebuild. heheh ild take more comfort if you said you sold a few a week nipper nipper
