Q:What great blood vessels of the heart have semilunar valves?
Q:What causes oil spot saturation on valve covers?
Sounds like bad valve cover gaskets. Not too big of a job.
Q:TORO Quick Link Automatic Sprinkler Valve (Jar Top) not working?
This Site Might Help You. RE: TORO Quick Link Automatic Sprinkler Valve (Jar Top) not working? I have checked this and ensured that the flow control is turned on. I have also found that: 1. Valve works in manual mode 2. Solenoid is getting electricity and water seems to be flowing in automatic mode but nothing is coming out of the sprinkler. I am not sure what could be broken as...
Q:EGR Valve...?
It does not help warm the engine. It is shut off at idle, and opens as some others have said when cruising. If it opens at idle, it will cause the engine to run rough.
Q:replacing valve cover gasket?
I would use Chevy orange heat resistant paint for the covers and as far as the gasket, when you do pull off the valve covers, you will have to clean the surfaces with a PLASTIC putty knife and maybe steel wool to smooth it out fine. DO NOT use anything metal on these surfaces as you might gouge it. Whatever you do, make sure you put rags over or inside the camshaft/valve assembly so you do not get any gasket pieces in the valves because you will have REAL problems then......Depending what kind of gasket (aftermarket) is made for your car, if it is cork, you will want to put gasket sealer on the gasket (Both Sides) first, and then place it on the surface and then put the cover on. Make sure that when you tighten the bolts, they should be torqued to specifications of your car. And if you go ahead and tighten them without a Torque Wrench, just make sure you criss-cross tighten, starting from the corners and working opposite and DO NOT over-tighten !!!!! I would strongly recommend that you torque them to whatever inch-pounds !!!!
Q:Does having a Torque Valve on a 2 stroke dirtbike give much more power?
The torque valve (it's called the power valve, by most manufacturers) changes the exhaust port timing, depending on the RPMs of the engine. The valve blocks part of the top of the exhaust port. As the engine RPMs increase, the valve lifts up. The distance between the top of the exhaust port's opening and the top of the cylinder is changed. When the piston is moving down on it's power stroke, the opening of the exhaust port is exposed sooner (due to the valve lifting up) and the ignited fuel exits the cylinder faster. This process of changing the exhaust port's timing, creates more explosive power for the engine. So of course if it was hooked up, the engine's performance would increase.
Q:What is the importance of engine valves?
Most, and check the service records for the car you are interested in buying.
Q:What happeneds when you have a cloged valve?
Are you referring to heart valves? They don't really get clogged, but can get calcified and what we call stenotic (the area through which blood flows is reduced). There are ways to manage valvular heart disease with medications, but some people require surgery and valve replacement. There are mechanical and biologic heart valves that can be put in place of a damaged valve. The surgery is one of the riskier ones, because it's on the heart.
Q:valves adjustment in 6 cylinder in line mercury marine?
From 0 lash turn the rocker arm nut 3/4 turn. Before you start, lay some rags under the engine to ketch the oil. The engine needs to be running. Loosen each nut until you hear the rocker arm stat to click, then tighten it slowly until the clicking stops, your now at 0 lash, now tighten the nut down 3/4 turn or 270 degrees, don't do this to fast the lifter needs to adjust. After adjusting, take a center punch held at 45 degree angle and punch the stud and top of the nut, this will assure the nut stays adjusted and wont back off. Put the valve cover on and wash the oil off, a spray can of brake cleaner works great. Remove the rags and your done. Happy boating. .
Q:Sewer ejector check valve placement?
the check valve would be installed just outside of the crock vertically. The noise I doubt is from the check valve itself. I'd guess it is the pump shutting off and the pipe isn't fastened securely, so it bangs. Check to make sure that the run of pipe leaving the crock is fastened securely. if this is the case the only other option I oculd think of would be to re-position the check valve on a horizontal run of pipe as close to the crock as possible. Most check valves I have seen for ejectors are compression type, it will be messy but not to complicated. Keep a bucket handy, when you crack open that check valve you may need it. Flush the toilet until the pump kicks on a few times, this should clear out most of the nasty stuff. You may also need a short piece of 2 pipe and some couplings to make up for the space of the check valve. If you can hear the water flowing out when the pump kicks on and don't hear it draining back into the crock when it shuts off, the check valve is probably still good.
