Q:Are they referring to the nozzle orifice or are they talking about the diameter of the nozzle? Does it mean the inner diameter of the valve like in a globe valve?
Can't improve on what you have except to say: If you don't ask for a full port valve; you will get an internal diameter smaller than the ID of the piping.
Q:It's just a small 1 cylinder 1000 watt generator but thanks to contributors here, I verified the exhaust valve is pitted after I cleaned it all up with oven cleaner a toothbrush. My question is can I just replace the valve itself or do I need an entire new head? The seats still feel smooth.
There is no need to replace head if the seat is good. Blue smoke indicates to rich a fuel mixture,white indicates oil consumption.
Q:people tell me i need to install new valves and valve guides
Maybe you simply need to re-adjust your valves? Or buy a Lancer.
Q:What are better valve cover gaskets for a car? Cork kind? Or the rubber kind? Or either rubber/cork kind?
For the inexperienced I would choose rubber it is harder to mess up by overtightening and if you clean the surface it will seal good
Q:I took my 2nd valve out to wash it (i couldn't find my oil, but it worked fine) and I've tried making the number face the mouthpiece, yet it still is messed up and won't let me play a lot of notes.
1) Try this first and if this doesn't work, go to #2. Oil the valve's body and gently put it back into the cylinder without screwing it in yet. Then, turn the valve until it clicks, and make sure it is really seated correct. Some trumpets have two clicks, and one is not the right one. So, you have to get the right click - which tells you that your valve is seated right. When your valve is seated right, then screw it in. 2) If you don't get a click when you spin your valve - look at the tubing on your trumpet and line up the holes in your valve with the tubing. When the valve is up, it will line up with 2 holes of the tubing, and when it is down it will line up with 2 other holes in the tuning. So, you can determine the correct positioning of the valve by looking at the tubing on your trumpet. But this is a last resort. I've never seen a trumpet where the valves don't click when you turn them.
Q:If someone is not born with heart valve disease... can a teenager or a 12 year old develop heart valve disease?
OMG, I can't imagine losing my dad or anyone else I loved at such a young age. But to answer your question, I think it's a lil of both. Or at least it certainly must seem that way right now. My dad is dying from cancer. He's 67 even still, I'm having a hard time with it. What your brother is going thru, is normal, I'm sure knowing that doesn't make it any easier for you. But maybe you could talk to someone like a therapist who could maybe give you some help in dealing with your brother as well as your grief over your dad. After my 2nd sister died, people would often ask how long we thought my mom would grieve. Our response was always, not everyone grieves the same, and death of a loved one is not something we get over. But after awhile, the pain isn't as constant as before each day gets a lil easier. Maybe when school starts you could talk to a school counselor or they could recommend a local one for you. In the meantime, talk to your friends or any family members. They know what you're going thru, they love you they will want to help in whatever way they can. Wish I could hug ya, cuz I know where you've been. Whether your loved one dies from a long suffering disease that you've known of or in a sudden accident, it's a horrible thing to have to go thru.
Q:my EGR valve has gone on my Vauxhall Vectra 2.0 DI LS, 1998, 5 DOOR HATCHBACK, so i am getting a new one next week, what i want to know is, is it an easy job to replace them if so how do i do it? or is it better just to let a garage do the job?
Easy. Just google it and it will tell you how. It will take a minute to change.
Q:I jsut got my valve cover replaced on my car what does that do?
It just covers up ur valves. Keeps them from getting damaged by other moving parts. And you could say that it keeps most of the oil in it so that the valves can be lubricated. Valves are moving parts so yes they do need oil to help reduce heat and wear!
Q:Water is seeping up around relief valve threads. Tried tightening but could not get it any tighter.
Donald; Don't try to tighten it, or replace it, it will fail. Lower the thermostat to no more than 120F degrees, and start shopping for a new water heater.
Q:my dad is going to go under heart valve replacement what are the chances of him surviving he is 58 years old and has copd
It depends a lot on which valve and why it's being replaced, but unless the COPD is very bad, the average chance that a 58yo man who does not have any other major medical problems will survive single-valve replacement surgery is better than 98% if the surgery is done by an experienced surgeon at a good hospital. The COPD will very likely mean that his post-operative recovery will be prolonged and difficult, but he should do fine.
