Q: My Rodeo 96 has a P0440 code (Evaporative Emissions Control System problem). I have visually inspected the hoses on the engine; double-checked the gas cap is tight; but have not looked at the fuel tank sensors and connections. I've noticed that the EVAP canister purge valve solenoid is switching non-stop (click-click-click noise without stopping). Is it the expected behavior?: I have seen many of the Rodeo's purge valves malfunction causing rough idle and that clicking coming from the valve. It is not normal behavior for that purge valve. Double check all hoses for any hair line cracks, they tend to crack on the bottom side alot. Otherwise replace the purge valve it make a huge differnce in the vehicles idle and performance. Also a intake cleaning service helps quite a bit too, most lube centers and shops can do it for about 50-60$. That cleans all the carbon out of your intake plenum, port runners, valves. It may help the valve to stop malfunctioning also, have seen that service clear all codes and bring back lost power and rough idles clear up.

Q: How would your car run if u did not have one on it? Do u really need to have a pcv valve? I have a 1994 Ford Econoline: PCV valves don't really affect the way a car runs. Unless you leave the hose to it open, creating a massive vacuum leak. They're to keep acidic gases from building up in your crankcase. Without it, you would need to change your oil a lot more often. Before about 1965 or so, cars had what's called a road draft tube, which through a venturi effect, drew out these vapors. Some sort of crankcase ventilation has been used pretty much as long as there have been cars. Many newer vehicles don't actually use a valve, but a calibrated orifice instead.

Q: I have a 1997 ford aerostar and my mechanic just called me and said that the pop off valve needs to be replaced, but it is attached to the line so the hole line has to be replaced to. I want to try to find the pop off valve to see if I can get it b/c he can't find the replacement part, what I need to know is what it looks like. or where it is on an aerostar, because I have 5 more sitting in the driveway and I can look for it.: 1. the pop off valve is normally located in the compressor so if it over pressures it will relieve some of the pressure. it's not in a line. #2. if it's a 1997 it doesn't have R12. it has R134. the only valve in the line is the port to check pressures and vacuum and recharge it. it could have one of those valves leaking and most can be taken apart and a new schrader valve installed. hope this helps.

Q: Check engine light came on. Had a diagnostic exam run. EGR Valve is gone. Do I REALLY need to replace this valve, or will the car run just fine without it? 1999 Chevy Malibu.: EGR or ''Exhaust Gas Recirculation'' system assists the engine during warm up (from cold start to operating temperature). By circulating hot exhaust gases through ''channels and ports'' in the intake manifold, heads, etc. the engine heats up faster and more evenly. Without it warm-up may take a little longer and it may run a little rough until it has warmed up.

Q: The hot water in my bathroom is leaking from the faucet. I've shut off the valve below the sink, but it continues to dribble out. Also, there appears to be some rust build-up. Could that account for a failing valve?: In some homes where the sink is mounted to the wall, as in your case, there may be shut off valves in the basement directly under the bathroom. If there are none there then you will most likely need to shut off the main water the open the bath room sink faucets to drain off excess water. Good luck.

Q: Valves regarding WC's: A flush valve (if you are talking about a toilet) is the flapper at the bottom of the tank. I suppose it could also be called a drop valve. At any rate, a flush valve is designed to rest in place preventing water from passing. When the flush valve is raised, trapped air in the bell of the flapper will cause it to float as high as possible, allowing water to pass without restriction. When the water level is low enough the flapper will float back down and seal the opening, thus allowing the tank to refill and be ready for another flush. Good luck. :)

Q: Hi! I have three brass gate valves surrounding a filter for my well. They are starting to show some signs of leaking. I realize that I might need to replace them... or, there seems to be a couple of places where they could be adjusted. Is this something I should do? Or, if I need to replace them, can you help me put a name to this type of valve so I can have an easier time tracking them down ?: The little brass nut under the handle is the packing nut. It compresses a packing material like Teflon or a graphite based twine or rope to tighten up around the stem. That is what keeps it from leaking. You can tighten this nut gently to stop leakage. That is what it's for. Just snug it up a little and it should stop leaking. The inline connections are simply hose threads, tightened by hand or snugged up with some wrenches. The small cap on the side of the valve is to drain or vent the branch line. It is simply finger tight. The valve is a 'Stop Waste' valve.

Q: i have a '96 buick skylark and my check engine light is on...i got it checked and the test said it was my EGR valve. does anyone know how to explain in lamens terms how to replace my EGR valve??????: The EGR Valve Location is typically housed on the intake manifold (the very top of the engine)( I think it is on the drivers side next to the throttle body) It's purpose is to recirculate a portion of the exhaust gas back into the intake manifold so it has to be connected to the intake manifold. It is a round diaphram, will typically have a Vacuum hose connected to it, and typically held on by two bolts. You should also use plenty of light and inspect the vacuum lines connected to it, they tend to crack and loose vacuum which would throw a code. Hope this helps.

Q: ok so my 1993 bonneville started shaking and its smells like gas fumes in the car, so i cant drive it cause i have a newborn baby.so i took it to the dealership, they said codes 53,54,55,42,66 came up. they said i needed a new cadiletic converter, so i went to a local muffler shop. they said it was glowing cause it was so hot and said that wasnt the problem.i called the dealership back and they said they cleaned the egr vavle but said maybe it needs to be replaced, well before i spend any money i wanted to get everyones opinion, the car drive great, only shake when ur at idle. and smells awful inside uld this be the egr valve ?: could be egr or fuel pressure regulator. while running pull vacuum line off of regulator if fuel is present its bad .

Q: I have a 1991 Toyota Supra turbo that has to have the valve stem seals replaced.It puffs white smoke upon start up,but it goes away.Just curious if the seals can be replaced while the head is still on the motor in the car.: Yes, you can. There's an excellent article that gives you pretty thorough instructions on how to do that in the link below. Note: If this doesn't stop the smoking check and replace your Cam Position Sensor O-ring, that can cause this condition as well. Best of luck.
