Q:bent exhaust valve?
that would be caused by high rpm with no load, had it happen in my car years ago, well before i acquired it. vacuum modulator line cam off, car was driven home for about 15 miles at normal speeds (OUCH, 45 in first gear in a 68 gto) bent 4 rods and some other damage that i do not remember.
Q:Honda CRF 450 Valve Clearances?
The valve seats in the head take a constant pounding when the valves close - causing the valves to move up into the head and tighten the valve clearance. Carbon build up on the valve seats and valves will hold the valves open a fraction (unnoticeable in the engine's performance) - which will loosen the clearance.
Q:my water shut off pvc valve will not move to shut off position?
Jeff B is right, the screw you see is for taking off the handle, nothing more. A quarter turn should do it. If it doesn't turn, lightly tap on it as you do.
Q:Does a diverter valve make the same basic sound that a blow off valve does?
I don't know what this Oscar Hoyas is talking about but a diverter valve sends the pressurized air back into the intake stream while a blowoff valve sends it into the atmosphere, a blowoff valve makes much more noise than a diverter valve, which is almost inaudible. Check into the function of a diverter valve as opposed to a blowoff valve if you are on the fence between the two.
Q:Is a EGR valve necessary?
It used to be a cheap fix. I haven't worked on the newer vehicles, but it used to be an F-shaped plug, with vacuum hoses, that you could replace in a few minutes. Price was under $20. The biggest problem, then, was decoding the codes! I just looked it up and it seems to be pretty simple, and similar to what I worked on. A small diaphragm valve that runs about $50. Ford would probably charge you $300 for the part and another $100 or so to put it on. The EGR valve helps with exhaust and, to some degree, gas mileage. In other words, if you live in a state with strict rules about emissions, you may fail the test. In proper condition, you may notice a little better fuel mileage. Of course, when I drove a sports car, I noticed that a good waxing helped my mileage. LOL I doubt that the Flomaster would cause a problem. This is a sensor issue that is, or should be, directly related to the EGR valve itself. Of course, I haven't worked on vehicles for years, so... Google this and see what you think. Location should give you some pictures to show where it should be on your Mustang and then you can see if you think you can do it. Then, check the prices. If your state is a pain, fixing it is probably cheaper than failing the emissions test. Besides, the more work you can do yourself, the cheaper it is. The only real difference between you and the guys who work in the dealership is a degree (piece of paper) and a fancy machine. You can do the same things they do.
Q:Digital EGR Valve - Firebird question?
Take the EGR valve off and see if it is internally caked with carbon. Also look at the ports it lines up to on the plenum and see if they are also clogged with carbon. If they are, remove the air intake tube from the throttle body and open the throttle plate. See if the intake plenum is also clogged with carbon. If so, and I think it is, you will need to get yourself a cumbustion chamber cleaning. Those 90s GM cars were bad for this. This will make it idle rough, and also lack as much power as it should have.
Q:Valve/pipe leaking from toilet?
Before you start taking things apart try this. Find out where the water is coming from. You may have to sit there for a while to watch for a drip. If it is coming from where the knob to shut it off is, there is a nut behind the knob. Try tightening it a little. Don't really lean on it. If the leak is from the line to the toilet do the same thing. Just tightening things may solve your problem at no cost. Best of luck.
