I think that is a VERY bad idea on a car with a hot-wire MAF sensor, and poses a significant risk of damaging the expensive MAF sensor. Frankly, I also question the need to decarbonize a modern engine...the tighter regulation of fuel/air mixture in a port injected car compared to old carburated cars means that there tends to be few carbon deposits. I haven't found much of anything in the various engines I have stripped down over the years. Nathan Nathan, Your not going to hurt it since the sensor can deal with 100% RH. Using a spray bottle is essentially the same thing. Notice i said SPRAY BOTTLE and not ppour it down the throat of the hose. I agree about the carbon thing, but engines to get carbon inside the heads. my 97 obw autopsy i saw alot of carbon on the head but very little on the pistons. nipper

http://www.aa1car.com/library/ic697.htm do NOT tell somone he needs a rough surface if hes never done it before. Thwey will usually make things worse. The surface must be smooth to a machined finish. But hey waht do i know, pulling a wrench since i was 5 (45 now) and just an automotive engenieer. nipper -
sigh.... Ok basics, the wider the throttle is open, the less vaccum there is. Close the throttle its at the highest (accelration is close to 0 in hg deccelration 28 in hg). http://www.imperialclub.com/Repair/Fuel/VacuumGauge/index.htm http://www.procarcare.com/icarumba/resourcecenter/encyclopedia/icar_resourcecenter_encyclopedia_gauges.asp There are many places to pull a vacume, and depending upon what it does, it can be choked, reverse or not even go to the engine directly. I would use a spray bottle and spray it down the thraot of the snorkle of the air box, AFTER the air filter. nipper

Going by my outback 4 screws once you get the plastic surround off (four screws on that too) 5 wire looms (one in the middle of the cluster) Carefully manover the cluster out (steeringwheel all the way down) i dont remember if it is 4 or 6 tabs The plastic isnt brittle so it wont break easily. nipper

NNONONONO this should be machine smooth, no scratches. Scrtaches are extreemly bad. They make leak paths. this is bad bad idea. nipper -
i used to work for Standard Auto Parts. We had a huge problem with counterfit parts from china. Dont assume that "they are the only ones that make them" Subaru does NOT make these parts, but the parts do have to meet Subaru spec to become a sunbaru part (and they are tested). Same goes with body parts, hence why you make sure your getting only OE body parts when the car is damaged. Now where do you think the rejects go? Also there is a HUGE business in counterfit parts, literaly right down to the nuts and bolts. I have been a design engineer and a buyer, i can tell you stories of vavles that would come in and have a 90% failure rate. now where do you think those failures went to? Look in any industrail supplu director (thompsons) ther are literally 100's of bearing manufaturers for example, but very few i would buy from. penny wise and dollar foolish. nipper

er um.... So.... Just remoove the instrment panel, take off the plastic cover (its held on in little tabs). GENTLY remove the pin, reset the needle, reinstall the pin (it pops in and out easily). Plan B get a used spedo head and rebuild the cluster. Cluster comes out in about 15 minutes. Worse case scenario is that the board is fried, go to ebay or junkyard and pick one up for 40.00 nipper (and im ashamed that you didnt think of this tsktsktsk) and there is no cable, man you get a newer soobie and you forget all this stuff.

Nothing to worry about, what kills the cat is raw gas, not carbon and water, which the car normally expells anyway. i havent done this since 1980, but it is still a tried and trued method. Thats why blown HG 's have one really clean cylinder (on any car but subaru's). One thing, point the car AWAY from the neighbors, and make sure you are upwind from the car. this makes a hell of a lot of smoke. Use a spray bottle. Do it untill the exhaust is puffy white. Dont let the car stall. nipper

yes they were on the forum, but its been a while so i cant recall. Well there are two issues here, not so much interference engine, but when you are stuck on the side of the raod, usually in bad weather, waiting for a tow truck, usually on a sunday, then the time it takes to reinstall the parts and the cost, its just better to di it with the right parts the first time. nipper not to mention the whinning passnger that is complaing.....
