- Q: We have a 2008 grizzly 700...Lately when we run the 4-wheeler there is a ticking like noise (as is something were loose). I have been told by a few people that it sounds like the valves need adjusting. Does that sound like what it is? Will it cause any damage to the 4-wheeler if we ride it before we get a chance to adjust the valves?
- They are correct. Well almost. The Rockers are what can be adjusted. They are too far away from the valve and are starting to hammer on them instead of just moving them. You will not cause immediate damage by riding it but you could wear out the rocker completely and drop a valve into the engine which would be very costly. Best to get it repaired soon. Make sure they install new rockers and springs. The main cause for this is poor oil maintenance or poor grade of oil being used. Always use a GOOD synthetic oil and your motor will last 10 times as long
- Q: So I was diagnosed with a bicuspid aortic valve a couple months ago, I am 20 now and I was told that the defect normal dosent cause problems untill late 30's-40's. I have been having chest pains and at times sever palpitations. Has anyone eles gone through this? Anyone older that has experience with this problem?
- Yes okorder /
- Q: My AC leaks and mechanic says it is shrader valve. Is it expensive?
- A Schrader valve is a simple push valve used to keep pressure inside a container or system, while making it easy to add more pressure when required. The valve stems on your car's tires are Schrader valves. The PARTS to replace a valve are fairly cheap, but labor and materials to repair an AC system may run the bill up.
- Q: I want to make a ram pump but i don't have any waste valve. So I decided to make it but i don't know howCould you help me?If you can send me pictures, video and something like that (Pleasssssssssse)
- I already answered this for you, but here we go again: Why do you need to make a waste valve when you can just buy one, if you need to make a waste valve, you need tools from machine shops in order to do so. BTW, it's not allowed to repeat the same question more than three times because believe me, people will think you're annoying and will assume you have a case of OCD. In addition to that, they will likely report your questions for violation to the community guidelines. Refer to the links below for the answers and rules
- Q: My grandfather is going in for a valve replacement.. and I'm really worried about him.. I just want some information.. any good websites if you have them.. I looked on google.. But if you have any good ones that would be great..No horrible comments please..
- Please see the webpages for more details on Heart valve surgery, Mitral regurgitation, Aortic stenosis, Aortic insufficiency and Artificial heart valve. There are four main valves in the heart. Mitral valve connecting left auricle and left ventricle. Aortic valve situates in the left ventricle at the beginning of the aorta, the main artery of the human body. Tricupid valve connecting right auricle and right ventricle. Pulmonary valve situates in the right ventricle at the beginning of the pulmonary artery carrying the impure blood to the lungs. (1) The valves may adhere together, causing a narrowing of the valve opening and obstruction to the flow of blood. This is usually known as stenosis of the valve. (2) Because of the loss of elasticity and distortion of the valve the latter may not close proerly, so that a leakage or regurgitation of blood results.This is known as incompetence of the valve. Chronic rheumatic valvular disease may affect all the valves of the heart but the most commonly damaged are the mitral and aortic valves. Mitral stenosis and aortic incompetence are the conditions which most commonly arise, although mitral incompetence and aortic stenosis also occur. Quite often, mitral stenosis and aortic incompetence develop in the same person.
- Q: Hi, I am a junior in high school and I play the trumpet. For the past week or so my 1st valve has been odd. It gets stuck badly when it hits all the way to the bottom, and I can't seem to get it to stop. Normally when valves are sticky I just use some valve oil and it helps a lot. But it doesn't seem to work this time. It is a Bach if that helps. I think there are other types of valves so I'll say that there is a spring inside from like the middle to top. If you could help me out that would be great! Thanks =)
- No, it's ok, they are both the same. I've been using trumpet oil on my trombone slide for the past 4 yrs. It is less expensive, ad usually in stock. It's not bad. If i've used it for 4 yrs. I'm sure you can use it too! my BFF even used to use my trombone oil, that's how i ran out in the first place. I hope you do well with your instrument! Both are made of the same oil products. But i don't reccomend using cooking oil, or vegtable oil, it is too thick and makes the slide/valves greasy and is very hard to get off. Hope this helps.
- Q: my valves are making a taping sound and i lost a lot of power and need to know will lose valves make me lose power so can someone tell me what they are seat on thanks

- Q: 1st valve: this valve used to never cause me trouble at all. THen, suddenly it would stick at the end of the press. I took it home, washed it, cleaned out the casing with the casing brush, cleaned out the holes with a mouthpiece brush, and wiped it clean. Then, i put a bit of oil and it worked fine. Then next morning, i took it out for a second and found it was sticking again. It worked fine afterthat, but why would a valve to that?2nd: this valve is very troublesome. It's sticky for no reason. i did the same thing as the first, but it stayed stuck3rd. Weird valve. One day, i dropped my trumpet (not like down the stairs or anything, just while sitting) and this valve just messed up. What happened, was that when the valve was screwed in all the way, it would be stuck. however, when i unscrewed halfwayor a little less it worked amazingly well. Can a slightly unscrewed valve affect your playing (aside from the clicking noise). Can a valve get dented, causing this?
- I think the reason why your valves are sticking is because they are building up sludge from being oiled too much, and yes, that does happen frequently. Remove the valves carefully, wipe them off thoroughly with a clean cloth, replace them correctly, and lightly oil them. Then try pushing the valves a bit before playing.
- Q: HI ever one i have a 1969 1500 beetle engine i have just but 1600 piston and barrows on it but when i but the rockers on i have no valve gap at all. ive wound out the adjusters all the way and i still can not get a feeler gauge between the rocker and the valve. Please help cheers Adam
- you MUST have the cylinder you are adjusting at TDC before adjusting the valves on that cylinder. take the dizzy cap off and rotate the engine clock-wise until the the rotor is pointing toward the #1 cylinder (the front at about 5 o'clock where the little notch in the case of the dizzy is) there is also a little V shaped notch in the crank pulley. this has to be aligned with the crack in the case at the top of the pulley. then take the valve cover off the right side of the motor and adjust the 2 valves toward the front of the engine (front is front of car) these are the intake and exhaust valves for the #1 cylinder. after you get them gaped to .006 snug the jam nut down. then rotate the crank EXACTLY 180 degrees counter-clockwise this will get you to TDC for #2. then adjust the back 2 valves on the right side of the motor (back is back of car) these are valves for #2 cylinder. then put the valve cover back on. rotate the engine another 180 degrees counter-clockwise, this will give you TDC for #3 which is the front left of the motor. adjust them and rotate the crank another and final 180 degrees counter-clockwise for #4 cylinder put the valve cover back on with new gaskets of course and you are done
- Q: Why would oil be leaking from a blow off valve?i own a 05' gti 1.8t, i have had the blow off valve for about a year now, its a HKS SSQV, but i just revently noticed that when it blows off, there is a spray of oil that comes out..... why would it be leaking oil through the blow off valve? i know VW dont really go well with blow off valves, but it hasnt given me any problems until recently....
- vw has a pcv system it recirculates the crankcase air into the intake, your car if fairly new, but this is most likely the problem. at least its the most simple to check / fix. i dought the turbo is gone if its the stock ko3s, they can take a beating. the pcv valve is the black saucer shaped peice (kinda looks like the stock diverter valve) , its in the TIP by your N75 valve. these get filled with oil and start to dump in into the intake. did you switch the set up to run the BOV on the cold side? like off the throtal body hose? if so, this could STILL be the problem. if you take off your lower inercooler pipe and look inside for oil build up. and pull the n75 valve out and check it for oil. id think aboout replacing the pcv valve with a catch can. your real problem is yet to be noticed if your dumping the air out and not recirculating it into the intake, the car WILL RUN RICH, as it reads the air it adds fuel, but with a BOV your loosing some air BUT keeping the fuel. so id expect to see some bad cats and o2 sensors good luck
