Q:I gotta 89 Crx si. Just wondering if you could put on a blow off valve and it work without it boosted

You could put it on but it would never operate.

Q:Hi. im wondering what reed valves do and can they put on a 4-stroke engine or not???Thanks for your help.Dune.buggy5

Reed valves were popular when you could get a street two-stroke bike. They allowed air to flow only one-way. I think Yamaha even had a nifty rotary valve thing that squeezed the air that the piston sucked so it would flow a bit faster into the combustion chamber. With a four-stroke, I don't think there's any advantage to complicating the air flow with a reed. That's what cams and valves do. You need to burn more fuel to get more power. There are several ways to do this. You can do this with more RPMs, more fuel/air mixture, or a larger displacement. But that's about power, not necessarily a reed valve.

Q:is it possible to check valve to piston clearance with out taking the heads off? I want to buy a bigger camshaft for my 351 windsor stock pistons with 1970 heads. cam is 230 duration (280) and 512 lift

No you can't check the valve to piston clearance without taking the heads off. I had a 289 bored out to 351 and ran stock 351 pistons. So your stock pistons should work with the new camshaft. I know I'm a girl but my husbands a mechanic and for fun we rebuild muscle cars.

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:Last year an echo revealed severe aortic valve regurgitation with low ef of 37 but ecg was normal. i am 36 yrs old. I have noticed that i often have chest pain when i lie on my left (especially after a heavy drinking or if my bp is high) but the pain subsides when i lie on my right or back. Is it possible that my aortic valve only leaks when i lie on my left side, if so, can I continue living a normal life without needing valve replacement surgery if avoid lieing on my left side. or i'm i fooling myself, is the heart damage progressing silently?

Hello, You don't tell us *why* your doctors think, you developed this problem with your aortic valve in the first place? Has there been any infection of the valve with germs, (bacterial endocarditis)? Did you have Rheumatic Fever as a child? Were you born, with stenosis or regurgitation of your aortic valve? Do you have abnormally early, clogging-up of your artery-linings with cholesterol?

Q:What's the safety valve (relief valve) type?

The four common types of pressure relief are the spring loaded valve, the rupture disc, the balance bellows spring loaded valve and the pilot operated relief valve.

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.
