Q: HAS ANYONE HAD VALVE REPLACEMENT (WITH PIG VALVE) OPEN HEART SURGURY. WHAT WAS THE RESULTS? HOW DO YOU FEEL NOW?: Unreal Online Market --- warfarin2.4gw.pw/1ac7e3x9

Q: is it possible to check valve to piston clearance with out taking the heads off? I want to buy a bigger camshaft for my 351 windsor stock pistons with 1970 heads. cam is 230 duration (280) and 512 lift: 289 bored to 351? Maybe possible to STROKE it to 351, but I've never heard of it. I have heard of people running that much lift with stock springs, but I wouldn't recommend it. It's easier to change the springs with the heads off, so you might as well pull them and check clearances with clay.

Q: OK, I would like to run my shorty headers open on my Camaro, but I have two questions.1. I heard valve damage may occur because cold air gets in there. Why isn't this the case with straight pipe exhaust, doesn't the cold air travel to the valves in that case anyway?2. Right now with my headers to off road y pipe I have 2 o2 sensors to throw the check engine light off, and it has worked. If I run open headers, will they still work?: Cold air doesn't get in to damage, but the valve needs a bit of back pressure. The valve will burn, crack or check, or the valve seat will do the same. The common damage is a small w crack on the valve face, which then leaks compression gases into the hot header resulting in erratic backfire and misfiring. The lack of back pressure can be compensated for by richer mixture, or grinding a wider seat. Get used to lapping in valves, or find some high performance sodium valves and stelite seats. You could run dumps, and only open the headers for short blasts.

Q: This happens when the sprinklers are ON and goes on for a minute after the sprinklers go off. Should I replace the whole valve or do I need to check the diaphram or solenoid head? In addition to leaking, I have noticed a more potential problem - water hammer. As soon as the sprinkler goes off, I hear this loud banging noise from the pipes underground. Water pressure is fine ~ 50. My guess is air inside the pipes is causing this. Is this because of faulty valve which is leaking?Also, any difference between the valves that are sold in Lowe's and Home Depot to that of commercial valve? My lawn guy says commercial valves last a long time.: The water hammer is due to the sudden closure of the control valve. They don't turn off slowly. The sudden shutoff of the valve causes the inertia of the water to slam against the end of the sprinkler pipe. You can device from a well stocked hardware store to place in you water line to reduce or eliminate the hammer. As for the leaking problem, I disassembled the control valve and found the diaphragm out of position. On mine, there is a very, very small key on the diaphragm that aligns it with the case. Also check for debris in the solenoid valve seat and anywhere else in the valve. I can't address commercial vs residential valves other than if the valves are brass, they are more durable.

Q: If I flush the toilet the drama begins. While the toilet is flushing, if I lift the lift of the lid of the tank cover NOT THE SEAT, water shoots up straight in the air from the top/cap of the fill valve. This is a picture of a toilet fill valve.: They okorder /

Q: When i disconnected my Diverter Valve and made it non-recirculating i drove down the street and my engine cut out on me. it will go a few feet and after the excess pressure is released (PSHH) the car cuts out. i reconnected the valve tubing making it rec-circulating and it works fine. im baffled i know VW is supposed to run a DV but last night i saw a stock VW GOLF running blow off and he was stock. any ideas? it is an after market DV made by forge.: Yea... The 1.8T is made so you have to recirc your dv. You can run a BLOW OFF valve off of your throttle hose, but thats a lot of redirecting and work for some silly extra noise. Chip that Passat to get some more turbyturbo noise. Y was there a stock golf with a dv? I'm confused...

Q: Offcourse temp control valve controls temp, and pressure control valve controls pressure....and so on. I am wondering, what are the mechnical differences in the valves body and how are they operated in terms of process control.: In principle all valves are flow control valves. What changes is the variable they are controlling. A temperature control valve controls a flow to heat or cool another fluid. A pressure control valve, controls a flow to maintain the pressure in a vessel. As pointed earlier, valves can be self contained, i.e., the sensor is part of the control mechanism, usually a diaprhagm which moves the valve stem. and a spring to adjust a set point. Or, they can be pneumatic or electronic, in which case there is an external power source, transducer and controller to adjust set point, gain, reset and rate. This gives additional flexibility, if needed, depending on the process to be controlled. .

Q: Hi all,My buddys ford 460 has stuck valves. Where do I start? Could I notice anything by removing the valve covers, or do I have to remove the heads? Is it possible to unstick them without removing the heads? Assuming they stuck from sitting. What's the chance it bent the pushrods if it was running when they stuck? Can I check this without removing the heads? I'm not too familiar with this engine.: a valve stuck in the open position when cranked by a starter motor can put a hole in the piston it depends on which 460 7.5L you have some are flat top some are popups where centers are raised ive seen both in stock motors motorhead is right you can free them but you'll wanna soak them down constantly for a week or so remember they didnt get like that over night DO NOT crank over with starter use bolt on balancer as you'll feel resistance should you encounter a stuck open valve its so much easier with heads off but you can see the guides by removing valve covers if your valves are stuck your guide seal are junk trust me

Q: I've been diagnosed with mitral valve prolapse, my doctor just told me that i need to setup an appointment with the hospital to look at treatments for heart mitral valve prolapse-to possibly have a heart valve replaced. I am wondering if i should setup an appointment with mayo clinice in minnesota to get another opinion on that? I'm wondering if surgery is an only option available to me, i have been taking beta blockers that have been no help for the past 3-4 months. Thanks.: at the start, you ought to talk on your typical practitioner. they might certainly answer your questions extra proper than all of us right here. yet, i can assist you be attentive to that your situation can certainly be very uncomplicated. I certainly have a kinfolk member with an identical ingredient and he leads an exceptionally frequent existence and could no longer desire a valve alternative. If he engages in very actual interest (alongside with taking part in soccer), he does get drained certainly, yet different than that, he's high-quality. In case they did no longer clarify it to you (it seems they weren't very informative) right here is going: Your mitral valve is nearly a sprint door that opens and closes on your heart. once you have a mitral vavle prolapse, what which ability is that as quickly as that valve swings close, it closes and definitely swings IN slightly too far. (Ever seen a swinging door? comparable thought) This reasons slightly a leak. it is a few thing which will ought to be checked each few years in the process your existence, to verify that it does not worsen. touch your typical practitioner and ask her or him those questions, just to be on the risk-free ingredient.

Q: what is meant by inherent characteristic for the steam control valve??: There are different type of valves, (ball, gate, globe, needle, diaphram) each have their own characteristics in how they operate and the effect they have on flow. Inherent characteristic would be an effect that valve has on the fluid flowing through it.(steam can also be considered a fluid ) An example is a globe valve used to throttle a flow does so by adjusting the size of its opening. In essense its a variable orifice. Flow through an orifice results in a pressure drop across that orifice. So, an inherent characteristic of a globe valve is a pressure drop.
