Q:How to adjust valves?
after someone says take it to the shop, you can get the real service manual offline and do it. you need good feeler gages and a good feel for it. does your require shims or are the rockers adjustable?
Q:what is the primary function of a valve position?
Are you asking about a valve positioner? If so, then a positioner is a device that measures the amount a valve is open or closed and then adjusts the motive force to be sure the valve is in the position the controller calls for. These are typically use in cases of very high differential pressure or where the valve actuator may be under sized or marginal.
Q:new head gasket. insane valve tapping?
Ok The push rods are fine. There is no order they go in. The valves are taping due to poor lubrication, also did you do a valve job before u put the gaskets on? Also Use STP oil treatment after replacing the gaskets its a thicker oil that lubes better. The water pump wont be ur only issue. it sound like there is some restriction in the cooling system, Firs check the upper radiator hose it should be hot not cold, check the reservoir its shouldn't be over flowing and make sure the V-belt is in good condition make sure there are no cracks in the belt. make sure The thermostat is installed correctly and Check the radiator it self if the radiator is back-up i recommend a new one if u cant affored it remove radiator and have i boiled out clean. Oh just for safe measure get a block test done just so u will know there are no cracks in the block
Q:Mid eighties GM egr valve problem
EGR valve got sooty,and rusty and dirty and then they dont work right. They either dont open or they get stuck open and cause the car to run lousey. If the valve has been i the car since the 80's it is probably about time to either clean it or change it. do you have haynes or chilton manual for the car? they explain alot.
Q:setting valve lash and proper method?
I truthfully have repaired alot of Chevy engines in my time. I continually adjusted them chilly while i became into development the motor or reinstalling products....much less muss and fuss and much less oil in each single place. The GM instruction manual says ( and that i've got been doing this for years ) is with the engine in the #a million firing place ( it is set via putting your hands on the #1valve because of the fact the mark on the damper comes close to the O mark on the crankcase front conceal. If the valves are actually not shifting then the engine is in the #a million firing place. If the valves flow because of the fact the mark comes as much as the timing tab then it incredibly is in the #6 firing place, and may be became over a million extra time to attain the #a million place.) as basically desperate, right here valves may be adjusted. V8- Exhaust- a million, 3, 4, 8 V8- intake- a million, 2, 5, 7 back out the adjusting nut ( 5/8's socket ) till lash is felt ( flow or spin the push rod...in case you could flow it up or down or spin it truly..it incredibly is loose ) while play has been bumped off, turn adjusting nut in a million finished turn ( to middle lifter plunger ) Use basically slightly chalk to mark which valves you have adjusted to maintain music ...desire I helped and sorry for the long dissertation.
Q:1+ Tricuspid/Pulmonic valve insufficiency?
Shashank has the interpretation all wrong. The information you provided us with only gives details about the Tricuspid and Pulmonic valves. 1+ valvular insufficiency means that these valves are letting a small amount of bloodflow backward into the chamber it came from. 1+ represents a mild degree of regurgitation which is normal in patients of all ages. I have it as well. If you are concerned about the chest discomfort you are experiencing, it wouldn't be a bad idea to see a doctor but as far as your test results are concerned, those results are perfectly normal.
Q:2001 honda accord EGR valve clogged?

Q:Blow off valve question,please help??
teh valve is designed for use with a turbo to prevent over boost destroying things! hence we do need a turbo. vary rare to be worth fitting to a car eg installing a turbo. much better to exchange for a car with a turbo as standard ( also insurance etc is easier to sort) the gas pressure relief valve only sounds nice to boy racers. everybody else thinks it very geeky.
Q:home water heater has 175psi pressure relief valve installed.?
OKAY...the 30 psi is bogus....I've never heard of that! The pressure coming into your house and the water heater is typically 70psi to 100psi....the relief valve is set to pop off at 175 psi....if the pressure in your water heater reaches 175 then the valve will pop....when this happens you need a new relief valve....you may want to figure out why this happened also......your heater may be set too high... try turning it down a little......but first check the incoming water pressure to your home....do this by buying a water pressure gage and screwing it on to an outside hose bibb and turning the hose bibb on......if the pressure is over 80 psi (which is what most plumbing code calls for) then you probably want to install a pressure regulator in the yard to lower the pressure......Example.....if you have 120psi coming into the water heater, and when water heats it expands and builds pressure then you could reach 175 psi and your relief valve will pop off.......good luck!!
Q:Can you clean and REUSE BURNED VALVES?
If the valve is burnt there is nothing you can do with it but replace it. If they only need cleaning up you can lap them in with a lapping compound the danger with that is that you need to watch that you do not get close to the edge of the valve, that is when you will end up with a burnt valve. The valve should not be flush with the valve seat that is way to close and the heat of combustion will have a stronger effect on the material.
