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?: Let's start from the top. Your check engine light has been on and you took it to be smogged and you probably didn't know that the check engine light on is an automatic fail. So you get the oil/air filter changed without a reason, just because. Next, the diagnostic tests point to the EGR valve so you have a mechanic replace it, that is instead of having the mechanic figure out the real problem The mechanic could have replaced the valve or not, but you didn't get the old one from him, so you don't know if it's been replaced. He disconnected the battery so the light went out. Now it's back on so the problem isn't fixed. Could it be a sensor. Well, sure, but proper testing would tell you if it was. My GUESS is the EGR valve and ports where the EGR attaches just need to be cleaned out but without proper testing, that is just a guess. My suggestion is find a different mechanic, one who doesn't just disconnect the battery to turn the check engine light off, and don't go in telling this new mechanic what you think the problem is because you don't know.

Q: hello my names matt and i have a 1997 eclipse 2.0 non turbo with 94k miles and the semi circul seal on my valve cover gasket has a small leak that i see oil dripping and i dont think the pcv valve has ever bin replaced could any of those cause my exhaust to burn oil maby a bad fuel injector? theres no oil in the top of the engine on the spark plugs when i check them all, the piston rings and the headgasket r not worn or cracked so idk what it could be some one please help: Valve cover gasket no PCV yes.

Q: I had to replace the seat washers/stems etc in order for the constant drips from the kitchen faucet to stop. It did; but when i went under the sink to turn the water valves back on, the hot water valve felt as something inside it went smooth??? i can turn the hot water valve left and right but nothing is happening. No hot water at all from the kitchen faucet..Also there's low water pressure from the cold water that only came about when I tried to turn the hot water back on from the valve underneath the sink: Unfortunately most valves used today are made of plastic that only look like metal on the outside. Sounds to me like you and I live in the same house. I have to replace four different shut off valves because they are stripped. I am working on the kitchen one right now. Stripped Valve with no cold water and very little pressure in the other valve. If you ever have one replaced by a plumber, insist on all metal valves. I will physically inspect them from now on before they replace them. Once stripped nothing you can do but put a new one on.

Q: My car hesitates on the highway 55 m/h and up after about 20 minutes of highway driving, I unplugged the EGR valve to see if it still hesitates, but the problem went away after disconnected the Egr, so is it for sure that the valve is bad? Just wanted to make sure there's no other component that could be also be bad. I have a toyota avalon 1997.: Sounds good to me,

Q: Our water heater (bought in 2007 so still fairly new still under warranty luckily) seems to release water from the pressure release valve quite frequently. Everyone seems to say that it shouldn't do it often and ours probably does it a couple times per day. 2 main questions - 1. Is there really a risk of too much pressure building up and the water heater exploding (that's what the sales guy at Lowe's said) and 2. Any idea what the problem might be/what we should check out?: Don't let anyone foul you with this question because you have a bomb in your house and that pressure relief valve is telling you it's building pressure and when it builds enough pressure you will know. Since this is under warranty I would recommend calling a service tech out to look at it. It could be just the valve but generally they only pop off when they build up pressure. If it were just a leak I would say just the valve. Have you checked the temperature setting on the valve. Maybe it got moved up to a Higher setting. Or even better stay and watch the water heater go through a heating cycle. But don't take this lightly.

Q: im having trouble locating the pcv valve on my 1979 oldsmobile. i have a 305 engine. i need to replace it asap, so any help would be appreciated. thanks in advance to all feedback.: Facing the engine, should be on your left valve cover. Has a hose attached to it and sticks into the valve cover.

Q: My eight month old daughter was just diagnosed with pulmonary valve stenosis. Anyone have an experience with this? Did you have cardiac catherization? Did that fix the problem?: Treatment okorder

Q: 1990 Pontiac Sunbird, I took a piece of hose going to the egr valve to try and see if it is working properly, but with car off, I can suck through, and blow out into hose going to egr valve, and it doesn't seem like there's any seal stopping air flow either way...is it supposed to, or what is this supposed to do?: won't be able to help precisely yet this is a image of it so do the the place's waldo with this hyperlink. it is in lots of situations linked to the intake manifold the PCV is on the valve conceal and all vehicles from approximately seventy 8 on have EGR's

Q: I just bought my first bike in 20 years, and as a result have had to pump up a bike tire for the first time in 20 years. I was dazzled to discover a type of tire valve that I'd never known about. The Presta.So of course, I need a pump with a special adapter, I didn't know to unscrew that nut at first so I accomplished a whole lot of nothing for awhile, and once I did open the nut, the pump kept slipping off the tire once I got anywhere near the tire' recomended PSI until I awkwardly held it in place while operating my pump with one hand, which of course meant less leverage and so while I got above the min recommended PSI, I couldn't get anywhere near the upper end of the spectrum. Why would anyone use these ridiculous contraptions? The fact that they are used means there must be some rationale. A brief internet search seems to find more forum posts with people saying the alternative (Schraeder) valves are more reliable and don't leak as much either.Educate me!: See okorder /

Q: Hi guys, my parents had me install a new faucet in their kitchen sink. It works great and everything, but after the install the hot water pressure basically decreased greatly. The cold water pressure is fine, but I believe after I had turned off the hot water at the shutoff valve, something in the valve got messed up and is blocking the water supply.: Copper pipes are usually soldered. You might want to call a plumber for this.
