Q: And why is it so expensive?So after many months of trying to figure out why my 93 Mercury Cougar V6 has been breaking down chronically, I was recently told it needed a valve job. At 21 years old and just over 83k, l suppose that's the big issue.What exactly is replaced/fixed with a valve job? Will my car run like new AND STAY THAT WAY? Thanks :): Oh your mechanic sounds a peach! But then again your not exactly clear! Define breaking down, Testing valves is a relatively easy job,if the mechanic owns a leak down tester, and results are conclusive! Using one I can narrow valve faults to specific valves, no question. But you need to know exactly what is happening. is the engine hot/cold, short distance or long, after re fueling or when going up hills, take notes, good ones, the more you can tell a tech about what/when it happens the better they can get to the bottom of it. Just saying it broke down is less than useless.

Q: I am buying a 2004 Ford Taurus tomorrow and want to know the difference between a 24 valve V-6, and 12 valve V-6...Now besides the obvious difference in the # of valves...Is one better then the other???: The 24 Valves were marked with DOHC on the Engine and on the outside of the car.

Q: Since the valve drain is usually open, I am wondering if placing the cap on the drain has made my water heater dangerous.: If it is the drain valve and not the pressure relief valve, you should be fine. The drain valve is not usually open, just when the sediment is drained out of the heater or when it is drained.

Q: Someone explained on chevy that valve guide clearance can limit lift.: Picture your valve stem running down through the valve guide port. The valve guild has a two fold function. 1. to seal the oil from getting down into the valve. 2. To align the valve and keep it straight. If your valve guide is worn you will get a puff of blue smoke each time you start the engine. The valve clearance is the amount of distance the valve stem can move from side to side and that also also it to move in the lifter too which will take it over limit. If you install the incorrect valve guides, ie too small, they will not allow the valve stem to move as easily.

Q: I think on old AC units They had a different valve than the shrader. It might be called a king? Anyway, I can't get my gauge to read the pressure. The needles don't move at all. How can I measure, refill this type of HVAC?: Unless you are EPA certified, you have no business checking the refrigerant in old AC units. If you get caught, you could face a hefty fine.

Q: I was woundering if anyone had a repair manual for this valve on a 2004 Nissan Maxima. I just bought the car and Im getting the P1800 Code. Any help would be appreciated!: The sensor is very expensive. It cost 199.00 from the dealer

Q: I have a 2001 Ford Ranger with a 4.0 V6. I recently broke the valve cover bolt on the top right hand corner of the passenger valve cover ( the bolt closest to the belt). 1. Can I drive it like this and since 7 of the 8 bolts are in it should it leak worse. 2. How do I fix it, and 3. How much would this cost to have fixed if I took it somewhere. Thanks for your help: easiest to just remove the valve cover completely and then there might be enough of the broken bolt left to get a pair of vice grips on it and unscrew it out, go to parts store and get a new bolt and a new valve cover gasket and reinstall.If you drive the car the way it is it might leak a little oil around the broken bolt.

Q: What is a valve adjustment? I wanted to do one on my 1994 Honda civic ex cuz my friends told me I should do one but I wanted to know howmuch will it cost? And what will it do to my car in performance and gas consumption? My car right now has 155k miles.: Leave it alone. Besides at 155k a Civic is junk not worth spending money on.

Q: My Dr placed me in the care of a cardiologist who ran some test and an echo scan reports i have a leaking valve but she failed to tell me which one and i failed to even think to ask. What are the results of leaking heart valves? I asked my mother and she says each one has a different result. What are they? Any help would be great. thanks.: There are four valves in the human heart (Mitral valve, tricuspid valve, aortic valve and pulmonary valve). If the heart valve is leaky, the doctor can hear heart murmurs through the stethoscope. Leaky valve may cause bacterial endocarditis, heart palpitations or even heart attack. Medications will be administered for prolonged period to control the heart disease complications. Echocardiography report will clearly state which heart valve is leaking.
