Q: after my hot water tank shuts off about 1/4 cup of water comes out therelief valve. i changed the relief valve. the tank is 6 months old: Do you mean the heating (burner or heating coils) shuts off. If that is the case then you may need an expansion tank. If there is a reverse flow valve at your meter (most locations now require this feature to prevent back flow of water to the main line.) the pressure in your system can build up higher than normal when the hot water tank is heating. Most systems have a small expansion tank installed near the hot water heater to deal with this problem.

Q: Is there anyway, from home, that I could rule out a bad heart valve as the cause for my heart palpitations and arythmia?: NO THERE IS NO WAY TO TELL IF YOU HAVE VAVLE TROUBLE ONLY SPECIAL TESTS LIKE A ECHOEKG OR A CATH

Q: I recently adjusted the valves and put new valve covers on my bug and now I have a leak around the fron corner of one of my valve covers. What happened? What can I do?: probably the gasket slipped or the bolts need to be tighten more but just snug them down.

Q: I was diagnosed with Mitral Valve prolapse...I'm 21, 5.5 tall and 130lbs, I had a healthy lifestyle...my doctor said that my case isn't really sever..but i'm taking medications to keep it this way...something i cannot ask my doctor about, would intercourse be harmful to me? and how should I deal with it??? is it okay for me to have children in the future? and could my MVP be cured without surgery??: You can lead a normal health life with MVP. What it is is the valve between the left atria and left ventricle doesn't close fully like it is suppost to and some blood seeps back into the atria when the blood is being pushed out of your heart. MVP is more common then you think. The doc even said to you that your case isn't really severe. MVP cannot be cured without surgery at this time. However you'll be fine. Just keep to your doctor visits as scheduled to keep tabs on it.

Q: Ok guys I have a 70 4 bolt main 350 40 over. I have a lunati 292 cam 230 at 50 degrees. 480 lift. The kit says 1.5 rocker ratio. No valve adjustments needed. I just boight edelbrock aluminum heads summit number 5089 64 cc with 185 intake runner . And comp cam roller tip rockers. That say 1.52 ratio. All my decks on the engine and heads are stock not shaven. I have speed pro pistons with .125 dome. Im using standard felpro gaskets. Ok my question is will standard lenght pushrods work for this build. They are 7.794 length. And will my piston head clearance be ok cause of my domed pistons. and do I need to find rockers that just say 1.5 ratio to make this work or are 1.52 the same. Thanks: Only way to be sure is to put clay on top of a piston and turn the engine over by hand and then measure the clearance on the indentation in the clay.

Q: i have a 1990 gmc sierra k1500, 4.3 v6. it has leaking valve seals its only smokes wen i first start it. so im not in to much of a hurry to replace them. wen i do replace them will i have to reset the timing and the valve gap? and could leaking valve seals cause loss of power or performance problems: sounds like valve seals ! no you don,t have to bother the timing ! all you do is remove the plugs, hook up a air compressor and screw 1 end of the hose into the plug hole, take off the valve pan, loosen the rocker and start the compressor up ! once the compressor reaches about 40 to 50 pounds then take out the keeper on the valve stem and replace it with a new seal, if you can get the umbrella type seals, after the seal is replaced put the rocker back on, turn the crank by hand until the rocker is on the low cam and torque the rocker nut ! then you do the same way to the rest of the valve seals !

Q: When looking at the head on my chevy 350 how do I determine which is the intake valve and which is the exhaust valve?: Intake valve will line up with the intake port from the intake manifold and the exhaust valve will line up with the exhaust port going to the exhaust manifold or header....intake is usually larger of the two.

Q: So I just got mu egr valve on my car replaced a year ago. Now it needs replacing again!? why might this be? shouldnt it last longer?: There is no guarantee on how long anything is going to last these days. Yes ideally they should last longer but yours didn't and it needs another EGR valve. sounds like a faulty unit to me.

Q: I have a Tippmann A5 and I removed the gasline from the tombstone and when i went to put it back in the valve washer is in the way. Please help: You examine your volecity with a chronograph your interior reach paintball shop would desire to have them, you additionally can purchase one on Ebay i would not propose a handheld get one you are able to set up on a tripod like a digicam. a diffusion chamber we could the liquid Co2 increase into gas to keep away from the liquid Co2 to circulate into your marker The low stress kit is designed for working Compressed air no longer co2 it enables with decreasing the the working stress of your marker so which you get greater cosistant photos use much less gas

Q: The time has come to re shim my 06 450, and I am having a small problem (I think anyway). The exhaust valves have decreased to below the required spec and need to be replaced with thinner shims (as is usually the case), but the left intake valve has for some reason increased its valve clearance (from 0.16mm to 0.23mm). Is it normal for the valve clearance to increase? I thought they would only decrease... Any ideas? Unless the valve is being held open by something. Many thanks, Jim: 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.
