- Q: Does a faulty pcv valve (Positive Crankcase Ventilation valve) cause excessive exhaust smoke ?
- most likely it will knock as well
- Q: I got a 2012 peterbilt 386 ...it just came back from the shop a few day ago to get injectors 4 and 5 looked at and repaired ....I'm getting a fault code for injector spill valve and a engine light ....I tried resetting the computer to get rid of the code but that's not it ... uld timeing of this cause the problem ...but other than that it runs like a champ so what could I do to fix this is it time cause I did probably get re timed when they repaired it
- The fault for the spill valve is not something you can correct with timing. When they repaired or replace injectors they need to be programed into the computer so they match the other injectors. The spill valve is in the injector and is there to return unneeded fuel back to tank. If this valve does not work you could be over fueling or run the risk of fuel cooking in the injector making a mess of the spray pattern. It should be telling you which injector is throwing the code and if it is one of the two that were worked on take it back.
- Q: I live in Houston (where it hardly EVER freezes during the winter..) This winter it froze and the valve on the sprinkler system flew off and water started shooting straight up. Now that it's getting warmer and I'm going to need the sprinkler.. I have to repair it. Is this an easy fix that I can do myself? Or should I call someone.
- If okorder /... If the brass body of the backflow cracked, then you will need to replace the whole thing. That link above has the best prices for these things. Good luck!
- Q: A question about a hot water radiator bleed valve. I read the advise on previous questions and bleed all my radiators except one where the bleed valve broke off when I tried to turn it with the key. My question is that on the other side of the radiator near the floor there is a black knob that turns which I assume should shut off the radiator. If my assumption is correct then I should be able to shut this off and then remove the bleeding valve and replace it without bleeding the system.. Does this sound right? Thanks,.JOE B
- Very easy but quite slow. Open the bleed points on the upstairs radiators and the system will fill evenly. Shut the bleeds when the water reaches them of course. If the pump is accessible loosen the big screw head on the top of it and the will bleed air from the pump. When you think the system is full and the noise of entering water stops then go around to all of the upstairs radiators and check that there is no further trapped air.
- Q: I mean dropping the valve seat. And some mechanic told me that it dropped when the catalytic converter got clogged and it hurt the engine. But the most I've heard is that if I want to avoid this from happening I should be running the engine a bit colder because the valves weren't made with the right specs and after a 100,000 miles they become a bit loose and when the engine gets to the normal temperature or just a bit above, the valve seats would drop. Does ANYONE KNOW ANYTHING ABOUT THIS?
- If the valve has dropped you will hear a ticking nose when the engine is running. It the valve hitting the piston. This need to be fixed ASAP, With a stuck valve you will experance back firing or lots of smoke could out of the tall pipe especially on acceleration. Either way if you are trying to keep your car I would have the problem correctly diagnosed and this will likely means you will need a top end rebuild. These little 1.9L ford engines were pretty tough but after XX amount of miles and so many years it time for some internal engine work.
- Q: I got a cold air intake installed on my vehicle and don't have any AEM bypass valve installed, for preventing hydrolock. If I drill a small hole(e.g 1cm) on the intake(short ram section) can that prevent hydrolock or do I still have to get one of those bypass valves?I'm looking for any alternatives, instead of those AEM bypass valves and was wondering if drilling a small hole in the cold air intake could help in preventing hydrolock, just as good as the AEM bypass valve.
- I okorder (i think thats it) for them, Im pretty sure thats where I saw them. Whatever you do though, dont drill a hole in it.
- Q: I want to change a stuck pcv valve on my 86 toyota pickup 22RE. I've used tons of lube and picked away at the grommet but i still can't get it out. Any advice?
- the grommet is being replaced so do what you have to to get the valve out. id grab a hold with a pair of pliers and go that route.
- 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: what's the function of a car valve???????????
- valve A way to turn on or a off of anything Liquid or gas or air works same as a switch does for power it controls flow of
- Q: This trumpet has been in storage in its casing untouched for about 5 years. I took it out and tried to play it but only air comes out and no sound. The 2nd and 3rd valves are hard to push down. What do I do to fix it? Thanks!
- Dis is a pretty common problem. The valves are in the wrong valve case or they are turned aound in the case. Take each valve out and check the number...... most have a number stamped near the top, or on the part around the spring. Get them in the right place with the notch in the case matching the little peg on the side of the valve and all should be well. By the way, if you can't get a buzz on the mouthpiece the whole problem is you alone.
