Q:My 97 Tahoe has a leaking A/C pressure valve. I went to charge the system yesterday, and when I finished I took the hoses from the charging gauges off. The pressure side valve leaked. I pressed it down with a small screwdriver yet still couldn't get it to seat. I looks like it might have a damaged seal around the valve.Can I replace the valve? And if so, how. Or do I have to replace the entire hose assemble as they connect to the compressor?Thanks
you can replace the valve--but when you take the old one out so will all the gas. If it just leaks a little the air tight cover cap should suffice to avoid this proceedure.
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:hii have just found out i have a genetic disease called multi valve prolapse but i want more info about itwhat are the symptoms? can it kill me? any info will help!!thank you
Do you mean Mitral valve prolapse? The mitral valve helps blood on the left side of the heart flow in one direction. It closes to keep blood from moving backwards when the heart beats (contracts). Mitral valve prolapse is the term used when the valve does not close properly. It can be caused by many different things. Most people have no symptoms, but some people have chest pain, a rapid pulse, awareness of heartbeats, migraine headaches, fatigue, and dizziness. In a small number of cases, the prolapse can cause blood to leak backwards. This is called mitral regurgitation. Mitral valves that are structurally abnormal can raise the risk for bacterial infection. Some forms of mitral valve prolapse seem to be passed down through families (inherited). Mitral valve prolapse has been associated with other genetic disorders.
Q:compare the structure of the tricuspid valve with that of the pulmonary valve??please help me

Q:Hi. I looked at instructional videos for installing shutoff valves and instead of simply unscrewing old valve, the plumber simply cut the copper pipe. Is this necessary? Why can't I simply unscrew old shutoff valves from copper pipe?
Before you think about cutting the pipe. You should know there is water pressure behind it. You must first shut your water off at the meter. If you opt to take on this endeavor by yourself you have some easy options. There are four types of connections to my knowledge. Soldered is most common and very effective but takes know how. Then there is compression, threaded (which involves sweating a connection on the copper, and then some genius has came out with this new type of connector commonly refered to as shark bite or gator bite (those being the top two leading brands). With these connectors all you must do is put the little plastic insert in the pipe then push the connector on. Ta da! Then your done. I would even bet they make a push on connector with the shut off valve. So to recap. Shut off water, cut the copper and remove burs from pipe, take that piece to the hardware store so you know you have the correct size of pipe fitting. Go home and push it on and then turn your water back on and your done.
Q:I have an '03 vw jetta and don't know if I should get a greddy blow off valve or an injen cold air intake? Any suggestions? I don't know a lot about either, what is the difference between them?
a cold air intake will produce more hp and tourque while a bov will help release back pressure on a turbocharged vehicle. ive got a 1.8l turbo and i went with a cold air intake. then again i was going for more hp. also the bov will produce an awsome release of air into the atmosphere. then again if you get the air intake like i did you will hear the wastegate on your turbo make that same noise. and trust me itll make some ppl think you got major hp under the hood. so if you want the hp and the sound get the intake if you want the sound but are satisfied with the hp get the bov. intake will also help mpg's to.

Q:I have a hot water oil burner. I need step by instructions on how to replace the pressure relief valve.Do you know?Please help me.
Your precise, the priority could desire to have long previous away with the previous valve. Your new valve could be defective. in the previous you substitute it however there's a reliable probability your furnish rigidity is to extreme. it must be filling at a extreme rigidity to start with and then as quickly as heated it exceeds the shrink. This sounds like a greater sensible clarification and could greater healthful the priority. while you're hooked to a municipal water furnish they could be in possibility of pay the cost of having a ''rigidity regulator'' put in. or you will could desire to foot the bill.
Q:I'm at school reading a mag and all the internet is blocked except yahoo. So i'm trying to figure out what the diff is between 3 angle versus 5 angle valve jobs.
Cylinder ports flow better with a fancy four or five angle valve job. If you look at most standard valves there is only one contact point all the way around the valve face that actually seals on the valve seats. The width of this surface in multi-angle valve jobs is just as it sounds. Instead on one 45 - 46 degree angle. the valve will have two to three additional angles toward the valve stem under the valve head to smooth out the intake flow of fuel and air into the combustion chambers. there also may one to two additional angles above the sealing surface of the valve for the same reason. The actual part valve of the valve face that sits on the valve seat may be very narrow 3/32 to .060 This is especially true of the intake valves. Not so true of the exhaust valves. The exhaust valves need all the cooling they can get and the valve seat is the only saving grace of cooling them off. Therefore the faces of the valves are a bit wider. The narrowed up intakes however are constantly bathed by cool air and fine droplets of gasoline.
Q:I own a 2001 Chevy cavalier Z24 with a dual cam... Just got it tuned up and noticed oil in my spark plug sockets, which leaves me to assume either the valve cover gaskets or the cam carrier gasket is leaking oil... I would prefer to so this by myself considering I'm sure it's going to be costly.. Anyone have any ideas on how I go about replacing either?
valve cover shouldn't be that much of a problem as long as you have some basic tools and some mechanical ability. Take it that its a 4 cylinder car, the size of the motor is very helpful when looking for tips. Just don't over torque your bolts when replacing. 89 in lbs is about normal on gm's valve covers
