Q: For instance, I am buying some new tires that don't have the valve stems on them, so could I remove my existing valve stems from my used tires onto the new tires? Is this recommend at all? Is it safe? Is it possible? Can this be done? why or why not? thank you.: Ugh you could but you can buy new valve stems for about 25-50 cents each. I would use new ones.

Q: Does anyone out there have any tech info or schematics for state of the art camless engines that run pneumatic valve train?: i don't!!! LOL LOL

Q: and i want to but over size valve seatscan i do it in a 1991 chevy chenynne k2500: Jasons $1500 quote is way over priced. Valve seats crack due to heat and age. Its a common prob with chevy heads really. Price at a machine shop to replace the seats and do a valve job will be about $400 If your wanting to go larger on the valves, then you will need new valves ($75-150) Now why do you want larger valves in a stock head? Most chevy heads has 1.84 or 1.94 intake and 1.50 exhaust valves. I had 1.94/1.50's on my 355 making 505 HP, and running mid 11's 1/4 mile in a camaro. I have now stepped up to 2.02/1.60 It might be cheaper and better for you to buy an aftermarket set of heads with the larger valves if thats what you want. Aftermarket heads range from about $600 to 1200 a pair. I bought a new bare set of alum brodix IK 200cc heads for under $700, then bought all parts I needed to build them with for about $175

Q: I have 06 Suzuki gsx-r 750 and i was wondering what are the signs or how do i know that my valves need to be adjusted?: what Bob said but by someone qualified i have busted cams because i thought i could do it just some advise

Q: where is the shuttle valve located in 03 land rover discovery hse ?: The shuttle valve is a part of the brake modulator this problem is addressed by the replacement of the brake modulator and that's a $1,500.00 dollar part plus labor but I believe that they sell a shuttle valve repair kit for around $100.00 dollars.....

Q: My eight month old daughter was just diagnosed with pulmonary valve stenosis. Anyone have an experience with this? Did you have cardiac catherization? Did that fix the problem?: I had a different heart condition in high school. Mine was called superventricular tachicardia (SVT) but it required a cathedar in my heart. I had the ablasian surgery twice. We're not sure if it didnt work the first time or if there were two seperate problems, but after the second surgery I havent had any problems. Speak more to your doctor, he should be able to tell you more information and answer all of your questions. For me the surgery meant putting me to sleep and inserting the cathedar through three arteries, one on each side of my shoulders and one in the groin. I have very small scars that arent very noticable and I went home the next day.

Q: I am modelling the production of phthalic annhydride and my process has a lot of FIC, LIC, PIC notations in circles on the connections. Moreover there are what i think are temprature and pressure notations in a square and a triangle. But most primarily what does a pneumatic valve do?: pneumatic valve is nothing but a valve which is operated with the help of high pressure compressed air. the can be thought of as an alternative of a metal spring... These could retract valves more quickly and reduce the possibility of piston-valve interference as long as pressure could be maintained. Additionally, the amount of seat tension required to keep a coil sprung valve under control results in greater peak lift loading, with added stress to the entire valvetrain as a result.

Q: ok im 17 and had really bad chest pains for like 2 years and the dr told me last year my valve was leaking and the pains have been getting worse what should i do?: Minor valve leaks are common - I'm 6'1 and I've got one and I lead a perfectly normal life. The chest pains are probably unrelated as a valve leak doesn't hurt, and a heart attack has additional symptoms which you haven't mentioned. It's probably working out too hard, atrophy, growing pains, or bad Mexican food. YES, see a doctor, always, but it's probably nothing. I get chest pains too (along with pains in other parts of my body - especially when my ex is around), and it's nothing.

Q: Can a clogged EGR regulator valve cause my car to stall out and die when it's idling at red lights?If I give it a little has it wakes the car up and keeps it from dying.One mechanic told me it was clogged up and that it can cause that issue. My boss says there's no way that's the problem... I say we've fixed cleaned or replaced just about everything else...Is this true or is the mechanic just trying to pocket a bit more $$??: Before I answer I am not specifically an auto technician but have worked on my own cars my whole life even rebuilding a 350 chevy small lock motor so I know a few things ???? ,,,, yes a malfunctioning egr valve can cause this issue but can be a number of things causing you motor to not get the right fuel/air mixture including a bad oxygen sensor, I suggest finding a second opinion to actually look at and test what is causing it

Q: what exactly causes a valve to stretch?: Valves do not stretch - where are you getting these ideas! If you're wondering how valve clearances get tighter - it's from the valve face pounding into the valve seat. The seat gets worn down and the valve gets worn down, causing the valve to get pulled higher into the head.
