Q:missing my pcv valve?
Will run at higher idle and suck all the oil out of engine, then run bad until engine locks up and exhaust would be smoking like crazy. plus other things. Suggest you replace and check oil level.
Q:what is an oil pressure relief valve?
its in oil pump some engines have a oil filter relief valve in behind the oil filter that can cause this problem but not certain if your engine does but worth a check
Q:What are valves in a car?
the more valves, the more complicated the engine, but yes, more power. a regular 4cyl engine has 8 valves, or 8V. 1 intake valve, 1 exhaust valve. (4x2=8) in a 16v engine, it can be 2 intake valves, 2 exhaust valves 4x(2x2)=16 there are engines with up to 32 valves, those are usually in the 8cyl engines. as a valve opens, it allows air into the combustion chamber, after the burn, the exhaust valve opens to let the burnt fuel out and thru the tailpipe. the faster the air can excape, the faster new air can enter. so more valves, more power. problem is, if they bend or break, very expensive to repair.
Q:Broke my trucks gas valves?
...Gas Valves???....WTF....
Q:Cleaning trumpet valves?
Remove the valves, wash them and the horn in warm (NOT hot) water with liquid dish soap. Dry with a clean towel, then oil and reassemble.
Q:Using thicker oil to eliminate valve clatter?
Valves don't clatter. Sticking or collapsed hydraulic valve lifter do. The use of the normal viscosity 5W-30 full synthetic oil contains a heavy dose of detergents. If gum, varnish or sludge is an issue, repeated use it may quiet things down. This is the least expensive thing to try first. If that doesn't do the trick it's time to (easily) replace the sticking hydraulic valve lifters. Thicker molasses oil may insulate noise while it's cold and heavy but it will never fix the issue.
Q:Which full valve guitar amplifier should i buy?
Well I have the Valve Jr. and the AC4. The AC4 is a good sounding amp, but even though it is only 1 watt less, the Valve Jr. is much louder. The AC4 is a great practice amp but not enough to jam with a drummer unless he is pretty quiet and you really crank the amp. Never heard one of the new Valve Sr. models but with all of the goodies they added it should sound really good. I had my Jr. modified but it still doesn't have all the cool stuff the Senior has. I think you would really like the Epiphone and at 20 watts you will be more than loud enough. My 5 watt Jr. will get very loud. All I own are low watt class A valve amps, it's the only way to fly!! The Marshall Class 5 might be worth looking at also.
Q:Testing my EGR valve?
To give you a good answer what kind of car is this? Make and model. There are two different types of EGR mechanical and electrical. What are the symptom that lead you to believe its the egr valve? And no unplugging it would no improve while leaving it disconnect and driving on it.
Q:bad valves honda civic??
Bad rings cause excess blow by in the crankcase causing vapors (heavy) to come from the dipstick tube as well as the valve cover. I can smell the exhaust smell in the breather vapors not just oily smell. Valves mostly cause smoking out the tailpipe as oil enters the cylinder and burns. excess oil usage is common as well. A compression test will indicate bad rings as one or 2 cylinders will read much lower on the gauge. valves can be seen as bad compression as well but often show more in the leak down in the gauge. the condition you stated of the valves is from oil entering the cylinder heads and burning. this is usually valve guides.
