Q:when heater heats water there is a small leak thru the releif valve. need answrers to possible reasons for malfuntion. leak is not continous.: Have you tried opening the valve for a couple seconds? Sometimes that will clean out the crud causing the valve to leak.

Q:Or is our money stinky? is the $59 we paid not equivalent to that paid by xbox360 ps3? Please help!! I am sick of getting killed every 5 minutes. Is VAC false advertising?: Well first off Activision fired infinity ward so chances are slim to none (they hired Bungie, guys who created halo).. valve doesnt have a thing to do with the game and generally Activision are lazy asses so id count the chances around 1 in 100

Q:i have a 1991 rm125 and i want to open the power valves myself can anyone tell me how to do thisTHANKS!: remove the carb abd intake manifold, they are inbetween the intake and reed cage. you will have to rejet .

Q:I have a 03 civic ex with 96k how important is it that I do a valve adjustment. The engine runs smooth.: Honda valves don't NEED adjustment unless you have serious problems.. If you give it the correct gas...keep the oil changed and don't beat on the engine, it won't need LOTS of work...

Q:what is engine valve timining ?: The valve's are in the head or head's and they need to be lined up with your crankshaft in order for the engine to be in time , if they was'nt in time with the crank they would hit at the wrong time and your engine would be junk.

Q:i have a 1997 dodge avenger ES with a 2.5L v6. im wondering if my EGR Valve could be bad i get about 14mpg on gas. my car has a poor idle but will not stall idle gets kinda bad if the airconditing is on. I did a complete tune up and yes it was done right. and i changed my Idle air control valve. after i changed the valve i drove a few miles and i got a check engine light for insuffecient EGR flow but then it went away and never came back. I took the valve off and cleaned it with carb cleaner. im trying to find out why my ide is kinda poor and if the car sits a few days it takes a little longer to start.my motor has 142k miles but has been properly maintained.: you should be getting way more than that on gas mileage at least on the road anyway,a bad egr valve will cost you around 3-5 miles per gallon if its leaking and doesn't seal of when it should, i went through this with out stratus ands its 2.4.it got real bad mileage,cleaning the valve didn't help it none at all, i went to a salvage yard and got a used one off a blown engine to try it to see if that would help it and the mileage came back up on it so i replaced it with a new one,you should average about 15-17 in town with that one and around 21 or better on the highway if its running right,id try that if everything else is right and you have double checked for codes and don't get any but the egr valve you don't have anything too loose,if you have had it scanned and dont come up with any other codes it would about have to be that or really low compression on the engine causing that too happen,a weak fuel pump believe it or not will cause one to get really bad mileage and run and idle bad also,and this is often over looked as a possibility,check those things if its not them we,ll figure out whats causing it,good luck.

Q:What is the primary function of valve seals?: Valve seals are placed over the intake valve guides so oil will not be drawn into the combustion chamber on intake stroke.

Q:my mechanic did a valve clearance check and said it was OK and when I asked him about the clearances he said that they were 6 thousands and 9 thousands however in my book the measurements are different they are as follow: ( i don't understand what he meant by thousands)inlet: 0.10~0.140.15~0.19 exhaust: 0.14~0.190.20~0.24so did he just make it up or did he get the wrong measurement.: The exhaust valves get hotter--the reason for looser clearances.Buster Brown is right about the rest.

Q:Or could you put a blow off valve on a supercharger?: No an No

Q:i have an 87' monte carlo ss, 64K on 305 w/ cam, headers, roller rockers and springs. ive been seeing blue smoke out of my exhaust ALOT during start up, but it also continues to smoke at idle, i've been told it's a good chance i need my valve seals replaced and was wondering what the general ballpark was assuming there was no other complications in the process of replacing these?: budget $300-400 probably to fix the stem seals. if you have ANY thoughts of replacing the heads with a performance set now is the time...
