- Q:how to replace a valve cover gasket on a 98 pontiac sunfire 2.2. engine?
- First off, you remove the PCV hose and unscrew the plastic nut that retains the PCV valve. Next you remove the air intake tube from the throttle body and the air intake housing. Now locate the bracket on the side of the throttle body that contains the throttle cable. Remove the 2 bolts from this bracket and remove the cables from the throttle body. You should now be able to remove the valve cover from any obstructions. If you are not cleaning the valve cover, there is no need to remove the PCV valve. If you are cleaning it with soap and water, take the PCV out. The gasket is one piece and rubber, but you may find it a pain to keep the gasket in the groove on the valve cover, so you might try some yellow weatherstrip sealer to help hold the gasket in place. Let it dry for a little while before reinstalling the valve cover, so the gasket doesn't 'roll' out of the groove on the corners, or it will leak heavily. Good luck.
- Q:my friend needs a flap valve replacement. does anyone no how serious this is, i dnt wanna lose my best friend?!!!
- pricey Vongirl, Congratulations on the lengthy lasting heart valve. frequently mechanical valves do not very last somewhat that lengthy. Mechanical, bovine, porcine and donor valves all positioned on out. It in basic terms relies upon on the timing. i'd say two decades with an same valve is somewhat magnificent. i wish, once you get your replace it lasts two decades besides!!!
- Q:Ok, I recent rebuilt a set of vortec heads, but the valves I got are a bit longer than stock, I believe .1 competition products pn I2552P. I also installed howards cam 98214 springs with 10° locks and retainers, the locks are +.035. I was just wondering if I would have enough spring pressure.
- You need to measure your installed height. No guessing here at all. Measure to be sure. If you don't have a valve spring micometer, you can use a std dail caliper's outside jaws. Remove spring, put retainer on, put 2 locks in, and pull up on retainer till it seats in lock groove. Now measure from spring seat on heads to bottom of retainer.. If you have to then you can measure to top of retainer and then measure thickness of retainer and take that off of your total. You have to know the installed height to figure spring pressure change. The 98214 springs has a rate of 411.. That 411 # per 1 inch and rated installed height is 1.700 So you take the amount of change from the 1.700 and X it by the rate of 411 and that's your total pressure change.. Then take or add that to your rated pressure (which is 115 #) and that gives you your new spring pressure So lets just say installed height is now 1.750 So .050 x 411 = 20.55 #, 115 - 20.55 = 94.45 # total seat pressure Now you need to list the cam your running, diff lift needs diff amount of spring pressure ***EDIT*** Thats a .465 lift cam. If your not winging RPMs past 5,000 then you can get away with a 80 # seat pressure spring, 6K rpm you would need about 5-8 # more seat pressure
- Q:i know its going to drop some oil, im just wondering to what extent? how much oil is going to spill out?
- Oil will not run everywhere. If you do happen to see a drip, simply wipe off what you see.
- Q:i am wanting to know if there is a diagram of the engine or at least if you have to remove the intake manifold to get to the egr valve.
- the accord is one of the best engineered cars that honda has ever produced and if the one you are looking at has a sunroof and leather it is a ex-L model witch is the top of the line model the milage on it is good and the price is as well your are getting a good deal but there are two things you need to know the automatic trannys that came in the v6 accord have alot of problems but dont let that worry you the trannys in the v6 accords from 98 to 02 the 6th gen model normally go out between 100000 and 110000 miles but honda extended the warranty on them to cover this problem so you wont have to pay for it that right there is a great bonus because even though the tranny will go out honda will cover the cost and you get a brand new tranny that is good for another 100000 miles now the second thing is the timing belt is recomended to be replaced between 90000 and 110000 miles but with only 76000 miles on it you have a ways to go before you have to worry about that I myself have an 02 accord 2dr ex-L 4cyl. and i love it it had 68000 miles on it when i got it and now has 80000 and i have only had it for 11 months but i drive my car alot and i drive it even harder i dont think i have ever shifted to the next gear untill it redlined witch i know is really bad for the car but even with as hard as i drive mine i have never had one problem with it well except for the damage i did the under carraige from having it lowered 2 and a half inch when i bottomed out going 127 on the interstate haha good times but yes you are geeting a good deal and if you get this car you will love it
- Q:I got a 2012 peterbilt 386 ...it just came back from the shop a few day ago to get injectors 4 and 5 looked at and repaired ....I'm getting a fault code for injector spill valve and a engine light ....I tried resetting the computer to get rid of the code but that's not it ... uld timeing of this cause the problem ...but other than that it runs like a champ so what could I do to fix this is it time cause I did probably get re timed when they repaired it
- The fault for the spill valve is not something you can correct with timing. When they repaired or replace injectors they need to be programed into the computer so they match the other injectors. The spill valve is in the injector and is there to return unneeded fuel back to tank. If this valve does not work you could be over fueling or run the risk of fuel cooking in the injector making a mess of the spray pattern. It should be telling you which injector is throwing the code and if it is one of the two that were worked on take it back.
- Q:I was just informed that my 4 year old daughter has been diagnosed with mild mitral valve regurgitation. I have been researching, but only find the information to apply to adults, not children.What general course is taken when dealing with children with this condition and what should I expect? Her pediatrician was treating her symtoms as asthma with breathing treatments, but, I was not comfortable and took her to my family physician, who sent her for the echo, which discovered this.I'm more or less just looking at our options...
- I am not completely familiar with this specific heart problem but my son was born with a CHD (congenital heart disease) called Tetralogy Of Fallot and has had 2 open-heart surgeries. He is only 2 years old but is and has been doing fantastic. I do know a few other parents with children with mitral valve regurgitation and they have had to have mitral valve replacements. When and or if this needs to be done depends on how severe the regurgitation is. You can go a LONG time with regurgitation of any valve. My son actually currently doesn't have ANY Pulmonary valve what so ever right now and hasn't sence his last surgery when he was 9 months. We are not looking for him to have a Pulmonary valve placement until he is about 5-7, so that will be 4-6 years with no Valve at all at 100% complete regurgitation!!!!! Hope fully your daughters isn't too bad and you can wait a few years for her to have a new valve. Children are more likely to reject valves and the sooner it is put in the sooner she will need a new mitral valve replacement. Pretty much anybody that gets a valve replacement will have to keep getting them every 10-20 years of their life depending on what kind of valve you choose, when it is placed and how good they do. Good luck to you and your daughter - heart kids are the strongest!!!!
- Q:Hi there - We have an old house with galvanized steel pipes. Our main water shut off valve leaks -- the leak is from the packing nut. A plumber came out yesterday and tightened it, and it now barely leaks at all, maybe one drip every 24-48 hours (which it probably has been doing for the 6 years we have lived here, we just didn't know when we bought the place). Rather than replacing the whole valve (which, apparently, has a high liklihood of breaking the pipes in the foundation, requiring jackhammering and whatnot), we are thinking of installing a new shut off valve higher up on the pipe, where I guess it's less likely to break. If we go for the second valve, is there a way to close up that old valve (hydraulic cement, tape, solder, etc.), so it doesn't leak at all? The tiny leak is coming from the stem of the handle - can we remove the handle and cap it off or something? (And thanks to those of you who answered my husband's question about the pipes yesterday!)
- There is a very simple fix to your problem. Get some teflon tape, turn off the valve, back off the packing nut all the way, twirl the tape into a thread (about 4 to 5), wrap it around the stem, reinstall the nut and snug it up. Done! While there is special graphite packing for this purpose, it is usually hard to find and works no better than the tape. You can apply a small amount of vasaline to the stem before you put on the tape to make the valve operate more easily. Only tighten the nut enough to keep it from dripping or it may become hard to open and close. You can easily add a second valve by removing the pipe above the old one and installing a piece of copper with a valve inline. Some will say you need to worry about electrolysis if you screw an adapter into the existing galvanized but I am sure you will replace the old pipe before that is an issue 20 years from now. Good Luck!
- Q:How do you remove a richdel sprinkler valve, when I turn the body of it, it doesn't unscrew, it just turns in place.
- if the valve itself has gone bad, then you can actually replace it without haveing to remove it. richdells are now called irritrol valves. they are not that hard to replace the guts and top part of the valve. if you can find the same valve off the internet or a landscape store, just take apart the old one and replace the insides with the parts from the new valve, and replace the top piece with solenoid as well. if you cant find the same kind of valve, just dig up a nice hole and cut the pipes and replumb it. thats pretty easy too. the more room you have on the pipe to cut, the easier it will go. but richdells are now irritrols. the parts will be the same, just have a different label. ive seen the richdells last over 20 years though good luck and hope this helps
- Q:When I put my check valve on my air line the air doesn't come through the air stone but when I take off the check valve it works. Also I switched the sides of the check valve and it didn't work. Click the link this is the air pump.
- Or if you can, go to petsmart and get one there. Petco tends to sell sub-par items and livestock. If you have a tank that is bigger than your air pump was intended, then you will have problems. Say you bought a 10 gallon air pump for your 20 gallon tank. The strength of the pump is only able to push air down to counteract the average depth of a 10 gallon tank, against the pressure of only that much water. However if it were in a 20 gallon, it may not be able to counteract the water and the check valve (which shouldn't be causing much of a problem anyways). Make your line shorter and see if that helps. You don't need tons of extra airline tubing coiled around. Cut it down to the length you need, and try again. Remember, check valve should be OUTSIDE of the water, in the direction indicated on the valve (as to which side is in, which side is out), and it should be closer towards the pump itself. The check valve just prevents any water from dripping back into the pump.
