- Q: I am working on my riding mower Briggs and Stratton 15.5 OHV. After replacing my headgasket my intake valve did not move when I turned shaft by hand. I took it back apart and believe I have my pushrods positioned correctly but cannot seem to get the rockkers back over the valves and rods. Maybe its because I am a girl and just need to man up but I thought it should be easier. Anyone got any tips?
- you'll need to get the clearance between the rocker arm and the valve, usually it's in the range of .060 - .080. then remove the nut from your rocker arm, install the rocker arm onto the pushrod, and valve spring (reminder, engine should be at top dead center) then reinstall the nut,and set your valve clearance.
- Q: Surly Pilots don't just switch the fuel selector valve of mid flight
- Not to take away from JFK jr's piloting skills but the possibility exists that he failed to check to see if the fuel valve was on in the first place. I do not know how far along in the flight he was, but a typical piston engine plane can get you up and on your way with the fuel that is in the fuel system. Why I know this, my flight instructor while training one of his students died in a forced landing due to engine failure because the fuel valve was not turned on. My flight instructor would allow his students to perform the preflight on there on, of course after many hours of dual training. The plane was a piper four place, it made it to about 400 feet agl before the engine stalled from fuel starvation. The irony of his death was from complications on the operating table from a broken ankle and a blood clot that broke loose. Checking for the on position of the fuel valve is on the check list. During emergency landing procedures, one of the functions is to turn the fuel valve off to reduce the possibily of fire. This doesn't answer the question but is a possibility unless of course he was well into his flight before the accident, in which case he probably moved the fuel valve to the off position following emergency procedures.
- Q: Bought a 1986 GMC 350day 1 started up good - idle was rough - idle really too low, when brakes where applied, it would backfire. (day 2) Changed oil which was really dark - oil filter too... ghanged spark plugs and wires. % 10 improvement... Engine lack power and vibrates but no more backfire.day 4 Changed Cap and rotor - % 30 improvement - day 5 Got the manifold gasket replaced. Same condition but silent... day 6 Changed coil in cap ... Changed fuel filter % 60 improvement... The thing ran like new... Full power I started beliving again..Got full oil pressure 300 kpa - no valve noise Ran 30 minutes on highway.... Valves started making noise especially on driver's side... Engine lost lots of power, and vibrates a lot... doesnt heat up to much but oil pressure seems very low. (day 7) Start up the thing, and even when cold and choke on, oil pressure not as good as in the beginning. What went wrong
- Sound like a blown intake valve. Do a compression test and if you find a bad cylinder, do a leakdown test. A leakdown test is where you pump compressed air into the cylinder with the bad compression. You need to make sure that both valves are closed which is determined by the crank position. If the air is leaking into the intake/carburetor, then you have a bad exhaust valve. Time to pull the heads, or do an engine swap. As for the buy a Ford guy, the GM blocks are the best out there. That is why almost all marine engines are GM blocks.
- Q: 1992 Ford Crown Vic, 102K, burns oil, no blue smoke, no leaks. My first thought was a valve job. Any other possibilities? Suggestions? What about an approxitmate cost for the valve job? Thanks.
- Hows your oil pressure Does the engine rattle when first started after sitting awhile It's been known that if your bearings are wore it can also make your engine use oil,crank and cam bearings thats why i wanted to know how the oil pressure is.. For the price of a valve job it could cost anywhere from 300.00 all the way to 600.00 depending on if your valve need replacing or not..
- Q: I need a ball valve that when you shut it off it sends a signal to a light that indicates that it is off.
- Shouldn't be a problem. all that's needed is a valve with elect contacts on valve stem. should be able to get one with two sets of contacts for on and off...
- Q: can anyone tell me the difference between Pressure Safety valveTemperature Safety ValvePressure Relief Valveused in a process industry
- Doleful is an adjective which means that it describes a noun. Similar words include: dreary, forlorn gloomy, grieving, lamentable, melancholy, mournful, pitiful, plaintive, sad, sorrowful. It was a very doleful day for Mary when she had to leave her friend behind. Lament is a verb. It means to grieve or to bemoan the loss of something. Frank lamented the death of his beloved cat. Woe is a noun. Other words meaning the same thing are misfortune, sorrow, suffering, grief. misery. Woe to the person who breaks his promise to me. Their woes became unbearable to handle.
- Q: what is a silicone purge valve.
- There are a number of things that will Toss out and ERG code on Fords (another reason I will never own another ford as long as I live) Double check all joints around the EGR valve and the tubes that connect too it. You may have a pin hole in one of the tubes or a loose coupler. If everything checks out there. Verify the vacuum line going to the EGR is not cracked, rotted, broken, or clogged. If it is replace the line. Next you need to check and make sure the valve is opening at the correct time. If the EGR is slow to open, becomes stuck half way or is opening to quickly, these will all toss out EGR codes. Then there is the possibility that the tubes for the EGR, or the EGR it's self may be clogged as well. In which case you need to remove them and clean them out. Hope this helps in your trouble shooting. Good luck.
- Q: why can't i just use solenoid valves hooked to a small bank of relays(using relay logic to control operation) connected to thermostats to control a multi zone boiler system? it would work, but can i do it, why must i use expensive zone valves?
- Its just an educated guess but I would say it would cause system shock if a valve just snapped shut as against closing gently. Assuming the system was shutting down as a zone valve shuts the control switch opens and turns off the plant whilst the valve is still partly open. With a solenoid unless you fit a timer to pre shut off the plant then shut off the solenoid you would probably cause some plant damage. Also by the time you have wired all that lot up you may as well do the job with a zone valve.
- Q: Well I had a Anginogram that said I have Mitral Valve Stenosis with the LVEDP was Moderately Elevated and My Right Ventricular Moderately Elevated and My Right Atruim is Moderately Elevated what do all this mean I see my cardiologists in two weeks to go over things. Oh yes they don't say how much the Mitral Valve is narrow.
- Mitral stenosis (MS) is narrowing of the mitral orifice impeding blood flow from the left atrium to the left ventricle. The (almost) invariable cause is rheumatic fever. Common complications are pulmonary hypertension, atrial fibrillation, and thromboembolism. Symptoms are those of heart failure; signs include an opening snap and a diastolic murmur. Diagnosis is by physical examination and echocardiography. Prognosis is good. Medical treatment includes diuretics, β-blockers or rate-limiting Ca channel blockers, and anticoagulants; effective treatment for more severe disease consists of balloon valvotomy, surgical commissurotomy, or valve replacement. The normal area of the mitral valve orifice is about 4 to 6 cm2. Under normal conditions, a normal mitral valve will not impede the flow of blood from the left atrium to the left ventricle during (ventricular) diastole, and the pressures in the left atrium and the left ventricle during diastole will be equal. The result is that the left ventricle gets filled with blood during early diastole, with only a small portion of extra blood contributed by contraction of the left atrium (the atrial kick) during late ventricular diastole. Patients with mitral stenosis prompts a series of hemodynamic changes that frequently cause deterioration of the patient's clinical status. A reduction in cardiac output, associated with acceleration of heart rate and shortening of the diastolic time, frequently leads to congestive heart failure. In addition, when AF sets in, systemic embolization becomes a real danger. Please undergo echocardiography test and check whether you have other heart defects such as mitral regurgitation and aortic insufficiency.
- Q: My pressure reducing valve (or restricting valve) was looked at by three master plumbers and they all said I need a new one. My water pressure has been low for weeks. It measures about 100 psi at the outside hose bibs, but it is very low inside and suddenly reduces after you turn on the facets inside. The shower is ok. My automatic sprinkler system is not able to work now due to low pressure. A relative of mine thinks we can just add a handle (as one is missing) on the valve and adjust the pressure ourselves. The repair of the valve is around $500-600! I am told in Texas that we have to have a permit and inspection to repair this valve. Also I was told by the last plumber that came out, that I have to install a expansion tank on my new hot water heater according to code. I'm not sure if that is a city code or federal. Please respond as to information you may have on this problem. The expansion tank is required I'm told when you have a pressure reducing valve for safety, is this true?
- The cost you quoted seems a bit high to me. Mine didn't cost anywhere near that amount in East Texas. A pressure reducing valve acts like a check valve when there is no flow. That is it closes as the pressure rises when you are not using any water. In this condition, the hot water heater can raise the pressure even higher since there is no place for the expanding water to go. That is the reason for the expansion tank. Without the expansion tank the pressure relief valve on the hot water heater can relieve unnecessarily or weep a bit.
