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: What are two problems assosciated with faulty heart valves, what are there causes, treatments, cures, symptoms, aftercare, etc?Thanks in advance!: There's just not 2 complications associated with heart valves, and which heart valves?, mitral or tricuspid valves?, aortic or pulmonary valves?, most of them causes hypertrophy of the ventricles or the atrium affected, symptoms mostly consists of either cardiac grade IV-VI murmurs, cyanosis or congestion of the heart resulting to dyspnea, the management for it is replacement of the calcified valves most of the time.

Q: What is the best procedure to check/adjust valve clearances? This engine is a perkins diesel inside of a cat generator. I know that he exhaust valve is .018 and the intake valve is .008.: take off the valve cover....you might also want to remove the glow plugs if you have trouble turning the engine over by hand. now make sure that the valve you are checking is completely closed by turning the engine by hand till you see the rocker arm to its highest level.....then slide your feeler gage between the rocker arm and the valve stem.....adjust if necessary.

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 mitral valve prolapse and I don't get why only some people get chest pains? and what causes people to get chest pains with M.V.P (mitral valve prolapse), like me. PLEASE HELP!!!!!!!: With MVP, your mitral valve is smaller due to extra tissue. This makes it a little bit harder for blood pumping through the valve to get through, which can often times cause an aching pain. As far as I've seen, this is not life-threatening and the pain can be treated with over-the-counter painkillers. Imagine you kink your garden hose while it is running. The water can't get through the hose and the pressure builds up. When you unkink the hose, the water flows freely. Your mitral valve has a permanent partial kink or blockage. The blood behind that partial kink can get blocked up and cause pressure in your chest. Be sure to get regular check-ups with your doctor, just to be sure your MVP is stable. Your doctor will also be able to suggest some pain remedies.

Q: One of the zone control valves in my heating system does not appear to be working. The thermostat is calling for heat, but no water is flowing. If the other thermostats call for heat, the valves seem to open as the pipes above the valve get hot from the water flowing through. The one that appears busted gets luke warm at best. All 4 valves in the system are fed from the same pipe, and the failed valve is the third in the series of 4 along the pipe (and #4 flows fine) so it doesn't appear to be something in the feeder pipe.Is there anything I can do to try and fix the existing valve, can I replace the valve myself? Would replacing the valve top of the valve (the green/gold portion) possible fix the issue (maybe a problem with the operation of the piston? Is there anything I ahve to do before removing the valve top aside from removing power to the valve?: You would need to isolate the valve from the line, and depressurize the system, and I would think that turning off the heater and letting the temperature fall would probably be necessary if you don't want a relief to lift in the boiler. If you make a mistake here you have a very good chance of being scalded to death, or permanently scarred. Also, you may need to sweat and braise the new valve with a torch, so you had better be sure you know what you are doing and don't burn your house down.

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: i have a 04 kia sadona i have been having issues with the van overheating someone told me to open the bleeder valve and let it drain then refill leave the valve open and if i see bubbles in the radiator than its a blown head gasket. is this true? is there a bleeder valve on this and if so where is it located? its not on the thermostat housing i allready replaced the thermostat.: Remove the radiator cap when cold and run the engine. Have someone rev the engine while the transmission is in park (with the parking brake ON), and you watch in the top of the radiator for bubbles. It may take a few seconds from the time they rev till the bubbles rise to the top.

Q: i hav no clue wat it is or what it does, but i was goin to buy an 08 mitsubishi lancer but then i read that the valve guides in mitsubishi engines wear out really fast and it causes some problems.what kinds of problems?how will this effect the car?Should i go ahead and buy the car?: you will burn oil, if you think it may be a bad deal look for something else. plenty of cars out their to choose from. good luck! it will give you poor gas milage, and burn up o2 sensors also.

Q: I have a road bike that has schrader valve tubes and my current tire is rated to 90 psi max. I ordered some new tires that are 100 to 120 psi max. Will the schrader valve tube hold that kind of psi? I dont really want to buy converters and new tubes right now.: These valves are used on large trucks which often run there tire pressure at 100 psi and there is no problem. I am a truckdriver and see no reason why they should fail at the pressure you are planning to run at. They are a reliable valve.
