- Q: Okay, I got a 347 stroker and I noticed a spot that was leaking under one of my valve cover gaskets. So I went ahead and bought new gaskets. But before I replaced the gaskets I noticed that my valve cover bolts wasn't tight. So I basically went out for nothing and get new gaskets. Anyways since I couldnt return them, I went ahead and changed the gaskets. And I tightened all of them pretty tight. And I noticed that I still have an oil leak at the same valve cover gasket at the same place. Why is this? I also used cork gaskets, did I tighten them too hard? How hard should you torque valve cover bolts/
- cork gaskets have to swell use rv gasketseal around bolts and corners
- 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.
- No, there shouldn't be any scraping sounds. Yikes! It may be simply that the spring guide is misaligned. I'd pull the valve and try to make sure it locks-in when you replace it. On Yamaha's, the valve guide locks in with the valve facing forward (or backward - but you won't be able to blow through it with the valve down). So pull it. Look to see if there's a number engraved on the top section of the valve, and if so... it faces the player. Once you slide it in, turn it side to side slightly. If it won't turn, the valve guide is in place. If it turns a little, you should eventually hear the valve guide snap into the groove and you won't be able to turn it. If the scraping sound continues, the spring may be bent and need to be replaced (easy do-it-yourself kits available on-line). As to the sound, my guess is that this is just a matter of adjusting to a MUCH smaller mouthpiece than you're used to using. Everyone sounds awful when they start. That said... You should also check to see that the spit-valve corks are there and sealing the tuning slide and third valve slide completely. They'll fall off sometimes, which creates a leak and thus an annoying buzz in the sound. It's a good student model trumpet, so congrats on the purchase, and enjoy!
- Q: I have a 66' malibu el camino with a 283 sbc and a powerglide transmission! I have bee noticing a ticking noise on the motor and it miss kind at a rhythm. I took the valve covers off and noticed pieces of metal right by the front of the motor on the head. It is where the #1 piston is. Some of them have kind of a rounded off shape to them. I dont see anything wrong with the springs. but its dark and i cant really see. I also noticed on the even side 2/4/6/8 some of the rocker arms are loose? Some may be loose on the odd side too. not sure, i didnt check them. I found them right where the hole is where im guessing where the oil comes in. What do yall think? It idles kind of rough and i have noticed a loss of power? do i have broken valve springs or something? Thanks for the answers!!!!
- on the valve stem you have 2 keepers, they are small and curved and it could be one of them ! someone worked on that engine before you and either did not put both keepers in or one popped out !
- Q: Anyone know where the pcv valve is located on a 2000 Lincoln Ls V6 3.0
- It should look something like a flattened top and should be black and in line with your fuel fline to the injectors.
- Q: What is the easiest and best way to fix a leaking shut-off valve on a toilet?
- Replace it there fairly cheap.Usally all you need is a wrench an pipe thread tape and a new shut off valve bably less than 20 bucks total.Just turn off the water an flush the toilet.Place a pot under the connection so it will catch any remaining water as you loosen the connection.There are 2 large nuts at each end of the shut off valve.Turn them conter clockwise to loosen an clockwise to tighten.Wrap the threads with pipe thread tape on both ends before installing the new shut off.Its probably one of the easiest do it yourself plumbing jobs there is.Once you have the new shut off installed an tightened turn the water back on an check for leaks.If it is leaking you may have to tighten your connection a little more.Good luck,I hope this helps.
- 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: I have a 98 Mitsubishi Mirage, seems there is a valve cover oil leak, i know this can be easily fixed by replacing the gasket.. but how will i know if the leak isn't from the valve cover gasket . Is the cylinder head gasket a major issue also .. if its not really the valve cover thats producing the oil leak should i not worry and just replace the valve cover gasket .?
- The valve cover gasket is not as big of a deal, if it gets really bad you will just start smelling a lot of burining oil. The head gasket can become a major issue, especially since coolant also flows through more internal part of the gasket. The question you need to ask is if the leak is closer to the top (valve cover) or farther down the block?
- Q: this valve used in the refinery.
- This is a 'Trip and Throttle' (T T) valve that is maintained in a 'Fully Open' postion during normal turbine operation. It is maintained open by a Hydraulic Control system that, should any of many shutdown conditions occur, the hydraulic oil will be dumped to its reservoir by the operation of a Solenoid valve, actuated by the shutdown signal, and the T T valve will immediately close, stopping the steam flow to the turbine speed control steam chest in a safe manner. The valve handwheel is then operated to ensure that the valve remains fully closed until the system is ready for re-start. The valve cannot be opened again until the shutdown condition has been rectified and the hydraulic system reset to restore the oil pressure to the valve. The valve however, can then only be re-opened manually and slowly until the turbine is brought to the 'Minimum Speed Control' Governor setting. When settled down at this condition and the steam chest valves are under the control of the Governor, the T T valve is swung wide open. This latches the valve in the fully open position until another shut down occurs,
- Q: I'm looking for a way to fix my noisy piston valves on my full sized Yamaha tuba. It makes a loud, metallic clang whenever any of the valves are pressed or released. Thanks!
- Piston valves normally have cork or felt cushions so that they don't clank when you operate them. You may be able to get replacements at the music store where you get your valve oil, and they may have a repairman on site or on contract who can do a professional referb on your instrument.
- Q: My car has been sputtering and hesitating when I hit the gas. My friend's boyfriend says it is a bad erg valve does that sound right?
- If the EGR valve is opening on Acceleration yes this would cause hesitation,but you have to find out why it is opening if it is.If there is a solenoid controlling the EGR valve this might be the problem.If you can put your finger under the EGR valve when the engine is idling,rev then engine up in park,if you feel the valve opening it is most likly the solenoid
