Q: I bought a plastic ball valve from Lowe's just a couple days ago and it is stuck, I haven't installed it in anything but it wont budge without a pair of channel locks. I tried wd-40 but still nothing, should I return it or keep working with it? and if I keep working what should I try?
=== take it back and get another valve .... if it doesn't work freely in your hand then the valve will be a problem if you install it ---- working with pvc you should use the purple glue that is waterproof and it is a good seal and no leaks when you have

Q: I threw a birthday party last night, all went well until 2am when a crazy (drunk!) lady cut all the wires from my heating system (i guess as a prank??? dunno, she is never invited back). I have everything up and running when using one thermostat and connecting the thermostat wires (red directly to tv, Brown directly to W, and white directly to T) and not using the two Honeywell zone valves (model number V8043F. How do I connect those two zone valves to the L8148E aquastat?The valves have on bottom Th-TR, TH and TR and the two top screws are labeled end switch.If you need photos I can take them :)Thanks in advance!

Q: I have a 2004 rmz 250 i was wondering if i could get some specific details on how to adjust and the spec's for the intake valves... thanks
Buy a manual for your bike. The question is far too broad to be answered here due to the complex nature of a modern valve train, like found on your RMZ. It involves removing the intake and exhaust camshafts to gain access to the shims underneath the buckets on top of the valves. You must know where to time the cams again in relation to the crank otherwise, it is very possible to destroy your engine if not installed properly...Hence the advice on obtaining a quality service manual beforehand... It's also why the shops charge a seemingly extortionate amount.
Q: Hi guys, Thanks for your advice. RandyK is right, my dad's GP told me that if we don't get the valve operation, his heart will swell in years time and might cause more complicated illness. Just let you know my dad had seen his cardiologists recently and had some scan or tests done. The results will be discuss in next appointment, they suggested that mechanical valve would be used if the operation go ahead. At the mean time I just hope and pray his condition will under control by medication. Wendy, may I ask you how old are you when you had your valve operation? I am too scare to suggest or encourage my dad to do the operation. Because if there is any difficulties or worse ...during operation, I will be the one send him away......If anyone have a relative like my dad's case,(76 years old had valve operation) please give me some advice.. Many thanks
Hi David, just saw your post. I was young when I had my valve replaced. I was 37, now am 42. My mother had her valve replaced at the age of 54. Honestly, that is the oldest person I know of that has had valve replacement. As with any surgery, there are alot of risks young or old. The older a person is though it may be tougher especially if he has a lot of other health problems. Just take all of this into consideration when you and your father are discussing all the details, etc. and find out any and all options that he has before proceeding with surgery. Best wishes to you both.
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?
The only way is to pull the cam covers and check them with a feeler gauge.This should be done at least once a year as part of your regular maintenance.
Q: do I need a new water heater or can this ne be fixed?
It can be fised, you just need a new seal. Measure the width of your pipe and go get a little package of them. They probably cost $2.99. Turn your water off at the street, then drain your water heater to keep it from flooding and possible problems. unscrew the joint replace the washer and put it back together. There is a book you can get at book stores that's called Hoe To Fix Damn Near Everything. It is a must have and has saved me thousands of dollars over the years. Good Luck, Jackie b
Q: Hi all,My 1995 nissan altima (122k on the odometer) stalled for a few minutes this morning. I noticed that one of the sparkplug holes ( where the cable from the distributer connects to the spark plug) is sorrounded by oil. I cleaned it out and it got filled with oil again. luckily for me, and by god's grace it somehow started normally and i drove home. I am sure its the valve gasket. There is not much oil leakage, the oil level is fine.I need to know if its going to damage my engine if I ignored the problem for 3-4days.Thanks.
The part itself is less than $100. It's a little rubber gasket that goes inbetween the valve cover and the engine block to make a tight seal between the middle and top of the engine. Depending on which engine you have (the 4 or the V-6), it can be a VERY simple fix with about an hour's labor because the valve cover is on top. However, some (very few) cars require you to remove the motor to get to the cover. If this is the case, 7 hours seems about right.
Q: what do the doctors do and is it dangerouse? aslo how do you get a cloged valve?
Are you referring to heart valves? They don't really get clogged, but can get calcified and what we call stenotic (the area through which blood flows is reduced). There are ways to manage valvular heart disease with medications, but some people require surgery and valve replacement. There are mechanical and biologic heart valves that can be put in place of a damaged valve. The surgery is one of the riskier ones, because it's on the heart.
