Q: Does anyone out there have any tech info or schematics for state of the art camless engines that run pneumatic valve train?: i don't!!! LOL LOL

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.: there was an extended warranty on the EGR valve to 8 years or 80,000 miles from new for problems related to insufficient lift of the valve because the port that the exhaust gas flows through gets plugged with carbon. if your car is within the 8/80 take teh car to a honda dealer for a free replacement of the valve and tube if you need to do it yourself or have someone else do it I can scan a bulletin if you want the details of how to do it. if you want that, send me an email by clicking on the icon above my name to the left of this answer and select email be sure to include your real email address that I can send an attached file to because Yahoo Answers doesn't allow attachments. Doing it this way keeps your email address and mine out of the searchable Yahoo Answers database hope that helps

Q: Carbon keeps building up in the EGR valve. WHY?? and HOW DO I PREVENT IT? The engine is in PERFECT shape otherwise.: If your problem EGR Valve is AC-Delco, it can be cleaned and will work like new and save you the cost of buying a new one. Also, I was told by a local auto-repair shop that EGR Valves have a LIFETIME Warranty... so if you have your receipt take it back for free replacement. If having to purchase a new one, Save Your Receipt. If your problem EGR Valve is aftermarket, replace it with a new AC-Delco. Aftermarket EGR Valves are crap and cleaning will not fix the problem. Same with fuel pump... install AC-Delco ONLY. 1995 Chevy Blazer 4.3

Q: We are using safety valves of gas and steam for detergent slurries. Why they do not function?: I suggest that you rethink that application. Even if the valve does function it might not pass enough slurry quickly enough to relieve the pressure overload.

Q: Valves regarding WC's: The proper names of the two valves in a typical home toilet are the flapper valve and the ballcock valve. The flapper valve sends water from the tank to the bowl during the flushing of the toilet. The ballcock refills the tank and also sends a small amount of water to the bowl during the flush.

Q: Where is the PCV valve located on 2001 Nissan Altima: either in the intake or the valve pan.

Q: I'm installing a shut off valve under my sink. can you tell me all the materials that i need to install it by myself because to hire some body else is very expensive where i live. i need to change the old ones because they are leaking very bad when i want to use the sink.thanks a lot: It sounds to me like they are leaking from the handle when you turn them on to use your sink? If this is the case all you need to do is shut iff the main take the screw out of the handle and remove handle. Then take off the packing nut and replace the packing material. There are only two types of packing either an O ring or rops packing. Talk to the guy at your local hardware store he can tell you what you have. You may not have to replace the actual shut off valve.

Q: i am hearing tapping on top under of vale cover sound like valve need adjusting: time to change oil, use thicker oil or yep, adjust valves. not a monstrous project but time consuming. Need torque wrench, valve cover gasket and shim kit to adjust. It's a pain as u have two nuts on each valve adjustment rocker bolt. tightening causes the lower one to drop sometimes so u may find yourself adjusting the valves 2-3 times each. I did it on my old Acura with 78K miles. ran smoother. i dropped in a pulley kit and cold intake as well but afterwards. the head was real clean as I change oil regularly. I had tapping even after changing the knock valve so I knew the valve job was needed.

Q: hi i just found out i have micro valve i and have allmost 30 years with willam sydrome any doctors know more what can happen what dose walking or others got to do with the valve will i stand for a longtime walk jump will one side get weeker then the other what about my hands and eyes my knees what will happend over the years when i get older ?: I think you mean mitral valve prolapse. I have this. When I was younger I had a heart murmur and did several testing and nothing else became of it. Until recently when I was working out, I had pain in chest that didn't quite go away and went to the dr. and did some testing and diagnosed with MVP. Do not drink decaffeinated drinks b/c it will increase your heart palpitations. You can also be prescribe a medication to help with your palpitation. It's a beta blocker medication. It helps with your heart palpitations, but you should definitely go see another dr. if the dr. you're seeing is not very helpful or see a cardiologist. I was told to just go about doing normal activities.

Q: I got a '99 bmw 740il that is leaking and burning oil. It shoots smoke out the exhaust when i first start it from burning oil. And the car misfires when idling, i did a tune up and the spark plugs were soaked in oil causing the tune up not to help anything for long cause it was missfiring the next day. Does this sound like the valve stem seals? I bought new valve cover gaskets and grommets and im gonna replace those this weekend, im hoping that will help. Comments please: The symptom of bad valve stem seals is blue smoke after sitting overnight. But once that smoke is gone, a bad valve stem seal won't have any effect on engine running or idling. And it certainly won't cause a misfire. Worn valve guides can do all those things. You have far more serious problems than just valve stem seals. Get a wet/dry compression test and a cylinder leakdown test to isolate the problem to either valves or rings.
