Q: I have a 1997 Toyota Corolla. My check engine light has been on. I tried to get my car smogged and it failed. I then got an oil/air filter change and just yesterday I replaced the EGR valve which was the result given after 2 diagnostic tests. The mechanic gave me my car and the check engine light was off, I've only driven about 5miles and the light is back on. I have to pass smog asap to register my vehicle. I plan on calling the mechanic back and telling him the light is on, but could it just be a sensor?: it could be a sensor ! the EGR code probably showed up because a sensor was interfering with the valve !

Q: I just installed a iac valve on my 2001 blazer but didnt go through the reset steps. Do i have to unistall and do the steps or go from here with the reset. Truck stalls out now and surges... Or could i just hava a defective part.: The okorder /

Q: Hi, i bought an xr250r 2002 model. I rebuilt the engine and put in new exhaust valves. After i did this proper compression in the motor came back and it wasnt blowing smoke anymore. I took it for a 'run-in' ride, and noticed that the engine was quite noisy. I guessed it was the valves needing adjusting. I got numbers for the valve clearences which were: .004 of in inch for the exhaust valves and .005 of an inch for the air intake. Now i have done this the compression in the bike is enormous, it is barely possible to kick over, and the motor is very noisy, there is a loud ticking noise which im guessing is still the valves. Is all this normal considering i have just rebuilt the engine, put in new valves and hardly ridden (one 50km ride)? I would like to keep riding it to run it better to see if the motor loosens up, but im scared to ride it as it is. Any advice would be greatly appreciated.: 2002 Xr250r

Q: My fiance needs his aortic valve replaced. He is 40 yrs old otherwise healthy. I am wondering how long he will be in surgery, how long he be in the hospital and any other info about having this surgery.: This is major heart surgery that is done on bypass (cardiopulmonary bypass, meaning the heart and lung machine. This is very serious. He may be in the hospital for a week or more. He may need cardiac rehab to gradually be able to do simple things.

Q: Hi all,My 1995 nissan altima (122k on the odometer) stalled for a few minutes this morning. I noticed that one of the sparkplug holes ( where the cable from the distributer connects to the spark plug) is sorrounded by oil. I cleaned it out and it got filled with oil again. luckily for me, and by god's grace it somehow started normally and i drove home. I am sure its the valve gasket. There is not much oil leakage, the oil level is fine.I need to know if its going to damage my engine if I ignored the problem for 3-4days.Thanks.: It wont hurt to drive the car. I would replace the valve cover gasket. I would get a complete gasket set with valve cover,half moons if they are separate, and spark plug tube gaskets. If the spark plug wires are soaked with oil and feel soft i would replace them also.

Q: I had some great answers to my question yesterday... I have decided to have the valve job done... Since I have decide to go this route... I need some reassurance, the few people I have suggessed this option to have now told me that typically after a valve job other problems will start showing up. They have said that the car isn't worth putting money into and to get ride of it.: well, is the car in good shape otherwise, like the tranny, suspension and the body?, if it is, then its probably wort a valve job, its cheaper then another motor.

Q: I'm picking up euphonium (brass instrument) after a 5 year hiatus. Can I still use my old valve oil and slide grease (Trombotine)?: Valve Oil--as far as I know, does not expire. I've had some valve oil for decades (I'm primarily a woodwind/string player, my occasion to use valve oil is rare) and it's still good. Slide grease--which hadn't been invented yet when I was in brass class--I am not so certain about. I'd recommend looking at it and rubbing a bit between fingers. It's probably OK but if there's been some degrading or separation of the ingredients--if it's turned gray or tan--then I'd buy new. Hm, I have some cork grease that's three decades old, and it's still fine--so there's a point of comparison.

Q: how long do people usually live after mitral valve repair?: From what i've got study having it repaired rather than replaced has a much greater helpful restoration consequence. The survival fee is in the mid ninety's % clever so curiously like an rather secure surgical operation. Hoping she has a rapid restoration.

Q: I want to find a cheap valve that will let me take a breath in from one place then exhale through a tube going out so that i can attach an airbag to the breathing end and make a little diving lung.: Creating a proper valve system for the creation of a diving lung is not as simple as you think. You require carefully balanced directional pressure regulation valves. A simple one-way valve (AKA check valve) would remain open and release all the air from the airbag as soon as the airbag was subjected to water pressure.

Q: what is engine valve timining ?: The valve's are in the head or head's and they need to be lined up with your crankshaft in order for the engine to be in time , if they was'nt in time with the crank they would hit at the wrong time and your engine would be junk.
