- Q: I got an engine knock and backifiring and no power not even to move the car just a few feet. I figured its the vales that are eather broken or burned out. I just started to take my top end apart to check and change borken or damaged valves so i can drive the car once again. My question is, when i take the valve cover off i can see what looks like the valves and the springs and something in the middle of the springs, now what iam i gona be looking at for a broken/damaged valve since i dont see any obvious damages but i could be wrong.
- you need to pull the head(s) off to see the valve. all you are seeing is the valve stem wich is not going to help you determine much. remove the intake manifold and then the head(s) the underside of the head (combustion chamber) is where you will be able to visualy inspect the valves. more likely you have weak or broken springs, lifters arent pumping up or your cam is going flat. as for the knock sound, that is a whole other thing to diagnose.
- Q: I have a 87 cbr600, consumes oil at a considerable rate. Took the engine out of the frame and disassembled cylinder head, block and pistons and found there is a thick layer of cooked-on oil over all sixteen valves. I figured the oil consumption was due to bad rings, but could it have been the valves?
- Do you remember when and how it smoked? If it smoked when you first started it but for the most part nothing else it would be the valve guide seals. If it smoked all the time it would be the rings. If it smoked during deceleration it would be the intake valves/valve guide. If it smoked during acceleration it would be the exhaust valves/valve guides. Hope this will get you looking in the right dirrection and good luck.
- Q: So just yesterday i bought a second-hand ytr 2320e. After i bought it, i washed it and tryed playing it, but when i press the first valve, there is this small metal scraping metal sound kinda like if you scratch a metal bowl with a fork. I think it has something to do with the spring but im not sure.also, i was wondering if the trumpet valves are supposed to be very easy to press, or if they take a tiny bit of push.
- I don't think anyone knows, because there's multiple Bibles. And people interpret it their own way, and re-print it with different scriptures. As far as I'm concerned, there is no such thing as a REAL bible anymore. And any beliefs we have today about it are all false. According to one bible, you will be sent to hell on both counts. According to a modern version, you will be excused for doing your wife, and in another bible, you'll be stonned for asking this question (Knowledge is a sin) Interesting that we are the only intelligent life on earth, supposedly made in God's image, and yet the bible says to stay away from the tree of knowledge. Sorry, I don't buy into that bullcrap.
- Q: I just got my water pump replaced on my Peerless boiler. Now my backflow valve is always dripping. I am unsure if I should cap it off or if the dripping will stop over time. It seems that there is some pressure comming from the vent. What should I do??
- They are like any valve that may not have to operate in a while, sediment in the line gets caught in the seat of the back flow preventer when pressure has been lost to one side. The valve can be disassembled and cleaned but is not for the novice unless you have a lot of time. You can cap it for now but get it repaired or replaced because you will have little protection in keeping boiler water from your drinking water if the pressure is lost.
- Q: I have a 3406b motor. It has blow by. This happened when I hired a mechenic to do a top end. I belive that he did not ajust the valves correctly or something happen to the motor. I want to gap the valves to see if this helps out. How would I go on doing this.
- try using this link here to help you out. Dont know if you have engine brake or not. but u should be able to still adjust the valves correctly if you follow along with the process.
- Q: I think I have a bad valve steam seals because when I start the car white-grayish smoke comes out of the back of the car. When let sit for 2 or more hours start car and smoke comes out everytime. Will a valve adjusment fix the problem? Thanks
- I agree with MC. If you have a leaking valve seal, it'll just be a matter of time before the other ones start leaking, if it's a high mileage engine. You might as well pull the head(s) and have all seals replaced. The kit you but has all the seals in it, not just one. You can check the valves also while the heads are off.
- Q: I have tried to adjust valves of Suzuki Intruder VS400 but they still tapping..so how to adjust them in the right way?
- if okorder and download the free bee manual for your bike.
- Q: behind the valve cover of the #1 and #2 cylinder there are 2 intake and 2 exhaust valves I need know (cylinder #1) which is the intake and which is the exhaust. thank you in advance.
- The intake valves are the two rocker arms in the center of the passenger-side head. The exhaust valves are the rocker arms on either end of the head. For the #1 cylinder, the exhaust valve is the one closest to the flywheel side of the engine, and the intake valve is the next one towards the rear of the car. For example, if you're underneath the car and looking at the head, this is the pattern: Ex #2, In #2, In #1, Ex #1.
- Q: does anyone have a bicuspid aortic valve and wrestle? my cardiologist told me that wrestling would put too much strain on my heart but i can feel that i'm fine when i wrestle so if you have a bicuspid aortic valve and wrestle or know anyone who has that disfunction and wrestles please let me know
- I was only recently diagnosed with a bicuspid aortic valve, and before then I had wrestled for 13 years. I think every case is different though when it comes to how severe the stenosis is within the valve. If you really want to wrestle, you should ask your cardiologist if there is any way you can strengthen your heart to the point where he thinks you will be able to wrestle. Another thing you can do is try and wrestle, but pay attention to any chest pains. at the first sign of chest pain you should stop, immediately. This is nothing to screw around with.
- Q: I am making a vacuum chamber and need to suck the air out by a tube. What valve do I use? Pin valve, ball, or ? What are they typically called? Compression valves? What if they are designed for water?
- Any valve rated WOG (water, oil, gas) is OK for vacuum. Maximum vacuum pressure differential is atmospheric pressure (14.7psi, 101.3kPa, 1 bar). For convenience, you might use a barbed valve which is sized for tubing (See Yahoo! Images: barbed conical gas valve). Any plumbing and heating supply, or commercial cooking equipment supply will have a variety of miniature bronze gas valves to choose from.
