- Q:Long story short, have a 2001 acura tl had a rough idle/ no start issue. figured out by disconnecting vaccuum from the throttle body the idle was fine with the TB pulling air through the disconnected hose port. The hose i disconnected leads to the purge valve solenoid. I removed it and it is closed (no air flow), restarted car with hose disconnected and solenoid still harnessed in (still closed). Just need more info on the function of this thing and what it should be doing.. Can i bench test it with +12V and ground on the two pins? Thanks in advance.

- Q:Hi, I have Orbit valve for a section of my yard. The pressure is really low when I turn it on with my remote. When I turn it on manually at the valve, the water pressure is much higher.
- Its possible the valve stem is corroded with stuff not letting it actuate properly open. Turn water off and unscrew the valve then actuate it electrically while watching for a full stroke. Make sure flow control is all the way open when inspecting valves stroke. Remember where you had it set when done or readjust. Also check the solenoid for corrosion and clean linkages. I would clean and coat with petroleum jelly. My guess is valve seat is gummed up so lube the stem and work it manually till it slides open and closed easy then test with the solenoid. Good luck!
- Q:I got a '99 bmw 740il that is leaking and burning oil. It shoots smoke out the exhaust when i first start it from burning oil. And the car misfires when idling, i did a tune up and the spark plugs were soaked in oil causing the tune up not to help anything for long cause it was missfiring the next day. Does this sound like the valve stem seals? I bought new valve cover gaskets and grommets and im gonna replace those this weekend, im hoping that will help. Comments please
- The symptom of bad valve stem seals is blue smoke after sitting overnight. But once that smoke is gone, a bad valve stem seal won't have any effect on engine running or idling. And it certainly won't cause a misfire. Worn valve guides can do all those things. You have far more serious problems than just valve stem seals. Get a wet/dry compression test and a cylinder leakdown test to isolate the problem to either valves or rings.
- Q:how to adjust the valves on a 20 horse power briggs and stratton engine on a sears craftman rideing mower model number 917.276824
- On that model number the valve clearances or as follows. Inlet valve...0.010... Exhaust valve..0.013. Set cold. Set hot... Inlet 0.002 and exhaust 0.003. Set piston on the rock.. That is: Piston at TDC (Top Dead Center) on the compression stroke. Undo the bolt or bolts a 1/4 and set the feeler gauges between the tappet and adjust so the feeler is a stiff pull. Tighten the lock-nut or nuts and repeat for the next valve. Good to go. mmalky: 50 years of diagnosing and fixing large and small mower engines.
- Q:Why would oil be leaking from a blow off valve?i own a 05' gti 1.8t, i have had the blow off valve for about a year now, its a HKS SSQV, but i just revently noticed that when it blows off, there is a spray of oil that comes out..... why would it be leaking oil through the blow off valve? i know VW dont really go well with blow off valves, but it hasnt given me any problems until recently....
- vw has a pcv system it recirculates the crankcase air into the intake, your car if fairly new, but this is most likely the problem. at least its the most simple to check / fix. i dought the turbo is gone if its the stock ko3s, they can take a beating. the pcv valve is the black saucer shaped peice (kinda looks like the stock diverter valve) , its in the TIP by your N75 valve. these get filled with oil and start to dump in into the intake. did you switch the set up to run the BOV on the cold side? like off the throtal body hose? if so, this could STILL be the problem. if you take off your lower inercooler pipe and look inside for oil build up. and pull the n75 valve out and check it for oil. id think aboout replacing the pcv valve with a catch can. your real problem is yet to be noticed if your dumping the air out and not recirculating it into the intake, the car WILL RUN RICH, as it reads the air it adds fuel, but with a BOV your loosing some air BUT keeping the fuel. so id expect to see some bad cats and o2 sensors good luck
- Q:I recently had an echo and they said their was a slight tricuspid valve leak but it was 19 and anything less than 20 is considered normal. I have no clue what that means. Does any one have and clue on what scale she was talking about. Also she stated that the machine are so sensitive these days that the majority of people are found to have some sort of leak. Is this the case??????
- finding on the severity of the valve situation it fairly is severe. If it have been severe you certainly could have indications that could assist you recognize previous to now. Ask the physician how severe the valve insufficiency is. A mitral valve prolapse could make you sense mild headed. The tricuspid valve insufficiency could convey approximately severe issues. There are various circumstances that would reason this. it fairly is great to your heart professional to describe your situation. In any experience it fairly is no longer something to fool around with or placed off. while you're actually not chuffed with the solutions do no longer hesitate to get a 2d opinion.
- Q:A diabetic patient undergone CABG having aortic valve problem.Cardiologist suggested valve replacement
- Can be cured by valve replacement... alternatively, if you can't/won't go through open heart surgery then you may be able to get valvuloplasty. A balloon is used to stretch the valve open. This does not last nearly as long as replacement, but avoids surgery. A third alternative would be to contact one of the percutaneous valve REPLACEMENT centers (Mayo, Cleveland Clinic, Columbia). This is an experimental procedure which replaces the valve using catheters instead of surgery. Advice offered here is not meant to be a replacement for proper evaluation and examination by a qualified medical professional and should not be construed as such.
- Q:I just installed three anti-siphon valves(jar top,orbit) for a sprinkler system the main water line is 3/4 then goes into my manifold (pvc)3/4 schedule 40,usually when you turn on the water it comes to a stop where you re valves begin then you either open them manually or their set up through you re timer, the problem im having when i open the main water line the water goes straight through the valves without me even opening them my question is can it be to much pressure or what can the problem be? any info helps thank you
- As George mentioned, I'm wondering if you installed them backwards; it happens (I've done it anyway). The other unlikely possibility is that these valves default to open unless they are powered closed (so try powering them to close). If they power to shut-off and open when they lose power, then you probably want to send them back (you will end up with a flood every time your system goes down). The other possibility is you got a bad batch of valves. I would: - Go to manufacturers website and check their FAQ section - Go to manufacturers website and check the specs on your valve model (normally closed?) - Call the manufacturer with valve in front of you and have them trouble-shoot
- Q:im just bored so heres my question who do you think is better valve games (hl2 tf2 css) or bungie games (halo) and why. whoever gives me the best reson gets best answer. personally i like valve
- Personally, I find Valve the better developer. Bungie only has one series it's famous for, the Halo series, and while the same can be said for Valve, because everything is essentially mods of Half Life, Valve is much more consistent in its games. Bungie's Halo was it's first big hit, and I don't disagree with how great it was. The sequels on the other hand don't quite match up with the original. Though they're solid games in terms of gameplay, I disagree with the many reviews saying they're near perfection. The first Halo was the best of the series, possibly because it was refreshing for the genre, but the follow ups just weren't as good. Valve is one of the best developers of a first person shooter out there. They hit it big with Half-Life, and also created the opportunity for mods to arise. Mods such as Team Fortress and Counter-Strike were excellent enough to be revised, polished and sold in retail versions. While Half Life's follow up, Blue Shift, was lackluster, I think Opposing Force made up for it. Half Life 2 took a long time to make, and I think it was well worth the wait. It's own follow ups, Episodes 1 and 2 were excellent, but short. The Orange Box, however, made up for that because of everything packed in it. An excellent Team Fortress 2, the refreshingly funny and innovative Portal, and of course, three Half Life 2 games. The service Valve provides with frequent bug fixing patches is also great for those with a decent internet connection. My only complain against Valve is the steam is required to play their games, but that isn't a problem in terms of gameplay enjoyment. Halo's multiplayer communities are strong, but the same can be said for Counter Strike: Source and Team Fortress 2. This category seems like a tie. While neither company did groundbreaking things in developing either franchise, I greatly prefer Half Life 2's graphical style, the consistency of excellence and innovations (Portals, Gravity gun, fun physics) from Valve.
- Q:Surly Pilots don't just switch the fuel selector valve of mid flight
- Most likely it was found in the off position because of impact forces. That's not uncommon. The NTSB report mentions that not only was it in the off position it was torn from the fuselage and the fuel lines to it were ripped off and the whole bottom of the valve body was torn away. The airplane hit the water in a steep angle and at high speed, roughly 1 hour after takeoff. NTSB figured it was in a 45 degree bank and beyond 10 degrees nose down...in excess of 4700 fpm rate of descent. Marks on the propeller plus all the engine controls as well as indications on the gauges indicate that the engine was operating at full power. Last recorded fuel flow an instant before impact was 22 gph. It wouldn't have been able to do that if the valve was off. In the roller coaster ride that the plane went through and the confusion he must have had before hitting the water I'm sure he didn't turn it off...he had all could handle trying to fly the plane. He became disoriented in reduced visibility and who knows what he thought was going on. The destruction was total.
