Q:Cannot pass smog-EGR valve?
it could be a sensor ! the EGR code probably showed up because a sensor was interfering with the valve !
Q:Heart valve replacement surgery....?
Open heart surgery is always a risk, as is any major surgery. The main risks are from infection and blood clots. The risks taper off very quickly within a few days after the surgery. Heart valve replacements are a common operation, with a high success rate. Life expectancy is generally better with a valve replacement; but not all valve problems reduce life expectancy to begin with. Sometimes the trade-offs are more of an issue with quality of life, with higher quality achieved with a functioning heart valve, so some people may be taking a medical risk to obtain higher quality of life. No one can tell you for certain what the outcome of this operation will be. The odds are very high that everything will go perfectly and he will fell better than ever before. There is a very small chance that he will end up worse To put the risks in perspective, a person i know had minor surgery to her knee - a simple 1 hour operation done at an outpatient clinic. Ten days later, a clot broke loose and she died in her sleep. I have had the same operation twice and didn't even miss more than a few hours of work. Another person i know had severe heart problems and docs said it was terminal, but an operation could prolong his life maybe 5-7 years. He had the operation and its now been almost 20 years and his cardiologist says his heart is healthy and there's no reason why he might not live another 20 years or more.
Q:What is a Valve Job?
The valves (located in the cylinder head) allows fuel/air into the cylinder and burned exhaust gases out. Valve jobs can be expensive if they have to replace the valves, and/or valve guides, valve seals, valve seats, valve springs, etc. A car with 83k miles should not need a valve job unless is was very poorly maintained. I think your mechanic is looking for some money from you. Although it's possible that one or more of those items you've listed had failed, I've NEVER had to replace a single one of those items in ANY car I've ever owned. All of my cars have lasted over 200k miles and not once have I had to replace any of those items. I've been driving for over 48 years. Find another mechanic before you go broke.
Q:missing my pcv valve?
what it really is is a check valve it will flow one way but not the other meaning it lets the motor vent out pressure and no air or debris can be sucked or drawn in its better to have a functioning one cause it can affect performance overall cause it usually is working with emissions devices now to be honest replacing it is almost mandatory, but you actually might not notice any difference at all after its fixed

Q:Bovine or Mechanical Valve for my Mitral Valve Replacement Surgery? Experienced people, please help!!?
My aortic valve (amongst other things) were replaced/repaired during an emergency aortic dissection surgery. My surgeon chose the mechanical valve for me. I am hopeful that it will last a long time (I am only 26) so that I can minimize the need to undergo replacement surgeries. Yearly, I see my cardiologist -- they do a CT scan and check to ensure the valve is functioning properly. The valve does have a loud click to it -- it's something that you notice a lot when you first get it, but after a little while you hardly notice it.

Q:Evap vent valve?
the evap system is one of the main reasons why most cars ses light is on.......we repair lots of these for all car brands every month.....#1 yes it is labor intensive but it is possible to do yourself if u have the proper tools...u would be surprised how many techs in this industry have no understanding of evap systems what they do and how they work...we have not replaced many vent valves,but that could be whats wrong....just for grins buy yourself a real gm gas cap and try before you make any repairs.....7 out of 10 times they fail any tests.....let your wife drive it there will be no issues on her trip///but you have a very nice truck and this issue needs to be repaired....
Q:Would a ERG valve cause sputtering or hesitating on my pontiac firebird?
Its EGR vavle. it is an emissions administration gadget. It stands for exhaust gasoline recuculation. It sends countless the exhasut from the engine returned by using. it is going to reason your difficulty. it is user-friendly because of the fact they gets clogged with carbon over the years and stop working. i might replace it to save on gasoline and it isnt extraordinarily expenisve to do or have completed.
Q:silicone purge valve?
A purge valve is used when a system or object can sometimes be filled with unwanted substances during normal use, as a way to eliminate those substances without complete disassembly. A 'spit valve' (a kind of purge valve) is built into some musical instruments to allow getting rid of saliva which builds up inside during playing. Snorkels used for skindiving often have purge valves (some even made from silicone) to make clearing water easier. A purge valve may be used to drain occasional condensation from inside a gas line. If this is too general, please edit your question to add details.
