Q:i have a leak on the front of that valve cover and the oil is going down to the headers,,how can i fix the problem.?how do i install da gasket do i need any special things??thanx for tha help

have a new gasket install !!

Q:Anyone know how to stop this from happening? I have gone through 4 since March.

are you sure its the egr valves going bad or not the egr solenoids causing you to get the code,that will make it appear that an egr has gone bad when it really hasn't,good luck.

Q:Hi, i bought an xr250r 2002 model. I rebuilt the engine and put in new exhaust valves. After i did this proper compression in the motor came back and it wasnt blowing smoke anymore. I took it for a 'run-in' ride, and noticed that the engine was quite noisy. I guessed it was the valves needing adjusting. I got numbers for the valve clearences which were: .004 of in inch for the exhaust valves and .005 of an inch for the air intake. Now i have done this the compression in the bike is enormous, it is barely possible to kick over, and the motor is very noisy, there is a loud ticking noise which im guessing is still the valves. Is all this normal considering i have just rebuilt the engine, put in new valves and hardly ridden (one 50km ride)? I would like to keep riding it to run it better to see if the motor loosens up, but im scared to ride it as it is. Any advice would be greatly appreciated.

Did you adjust your cam chain?

Q:Im replacing the valve stem seals and i dont know how to remove the springs and with the valve compressor wont fit in the engine

Do NOT do what banit said, if you did his technique once you remove the keepers the valve would drop to the bottom of the cylinder and require a tear down. You must get the piston be at top dead center on the cylinder you intend on removing the valve springs from and you cannot do any other valves besides the ones on the cylinder you brought to top dead center. You can take the rocker arm off the top and take the push rod out then when at top dead center using a spring compressor you can take the keepers out, or if you do not have a spring compressor (proceed at your own risk) you can get an oversized socket and a dead blow hammer and place the socket over the top of the valve spring with the octagonal side towards the spring and give it a decent hit, but be aware the keepers will pop out and you may lose them if you are not careful.

Q:compare the structure of the tricuspid valve with that of the pulmonary valve??please help me

Structure Of Pulmonary Valve

Q:I bought my first car recently. but it has a high idle and smoking problem, i already replaced the spark plugs. I've been reading about the exhaust gas re-circulation valve. but i cant find it. where exactly is the EGR valve located in a 1999 KIA Pride?

all EGR valves should ( unless a very odd engine) on exhaust manifold. they will have a tube outlet returning back to inlet manifold and a control mechanism on it ( electrical connection) . these valves are known to carbon up and fail both due to soot.heat .wear etc. very possible this is the problem. a temporary fix can occasionally be found by soaking over night in cleaning fluid such as easing oil or petrol etc and washing out but this sort of fix never lasts. be aware these valves are not cheap.

Q:What are Atrial valves??

The aortic valve is one of the valves of the heart. It is normally tricuspid (with three leaflets), although in 1% of the population it is found to be congenitally bicuspid (two leaflets).[1] It lies between the left ventricle and the aorta.Check the link below for more information!

Q:I would like to know about the signal pneumatic valves are drivesn (PWM,PCM?) and about their bandwidth and bit rate. Where can i find info?Thanx!!

Norgren okorder . You will be able to use the valve island configurator, view and download 2D and 3D CAD drawings and receive a list price for complete valve islands. The VM10 is suitable for packaging and textile machinery, electronics manufacturing and many additional applications.

Q:IT USUALLY TAKES 2 SECONDS TO START THE MOTOR. NOW, IT TAKES OVER 40 SECONDS AT 7 AM. IT ALMOST KILL THE BATTERY. IF YOU PARK FOR 1 HOUR, 2ND START TAKES 10 SECONDS. IS THIS HAPPENING BECAUSE THE VALVES NEEDS ADJUSTING? HOW AND WHAT IS THE EASY WAY OF VALVES TUNE-UP?

Good call, it most likely is the valve clearance. As the valves wear, they get tighter until they actually stay open a bit (when cold). As the engine warms up, the aluminum head pushes the cam away from the valve stems a bit, and some clearance comes back. Check 'em, adjust 'em, and you should be good to go. For most chinese 150's, you'll need to remove the plastic around the engine, then pull off the valve cover - you'll see the rocker arms inside, with locking nuts and adjustment screws. Set the crank at TDC on the compression stroke (about 1/2 turn after the intake valve closes) and then adjust the clearance - get specs from your manual, or just make sure that there's at least 0.1 mm gap if you don't have the specs.

Q:My pressure reducing valve has gone bad. This looks like a pretty simple change. My question is do i loosen the union nut first (after draining water line), then loosen the whole valve??? Then reverse to install??? Any info would be great....

some reducing valves are adjustable. if this one has a locknut witha screw on good thats probable the explanation for loss of psi. via turning the screw in you advance the psi. if it has no screw examine the score on it. you like 60-a hundred psi variety. if nonetheless no answer do away with the valve and see if sturdy rigidity comes out of the meter. its a fashion of removal and a splash attempt. it particularly is the meter. you may troubleshoot its one or the different.
