Q:hello I am having trouble inflating my back wheel tube. so i guess i will just tell you what happened. well i came back from the bike shop with a presta valve adapter and i put it on my tube. it fills up too near full psi but just after a ride around the block it is flat. i have no idea why. please help me! also its a mavic tube 700 x 23, vittoria rubino pro 700 x 23 tire, and a vuelta xrp 17 deep v back wheel. thanks!

Did you take the adapter off? It is only intended to fill the tire, you take it off and close the valve.

Q:I have a 97 Neon. The Canister Purge Valve circuit gives a code 31 stating that it has a problem. I've replaced the valve, which didn't make the code go away. I removed the battery for a few hours, and the code went away. I drove for about 2 weeks and the code came back on. If it's not the valve, where do I look next?

Could you describe this canister purge valve? Not sure what you are talking about here. Is it part of the emissions, part of the radiator, or what. I am just guessing it's part of the emissions. In which case, I need to know if it has a smog pump. Could be the pump, could be a clogged up cat, could be a bad EGR valve. Need some more info to help beyond this point. Good luck.

Q:Hi. im wondering what reed valves do and can they put on a 4-stroke engine or not???Thanks for your help.Dune.buggy5

reed valves are in a 2 stroke cylinder head they are exactly like they sound like in a clarinet.. when the piston rises they are closed due to the position the port is in the cylinder . when the piston is down stroking it creates a vacuum hence the reed valve opens and the piston starts to rise closes the reed valve.. 4 cycle engines have mechanicaly activated valves from a timing chain and a camshaft which controls when the valve opens so the answer is NO NO NO

Q:I got a 318 V8.. I cant seem to locate the valve cover to replace... but I did notice that some of the replacement gaskets/filters are from the 91-93 dodge ramcharger.. Is it possible for an newer model to fit exactly on my 1989? are all dodge 318 the same size?

You obviously just suck at anything to do with cars and should go neck your self asap

Q:I'm installing an under-sink water filter. For the saddle valve, how do I drill the 1/8 hole through the iron pipe? What is the easy way to do this? Seems like I will be slipping around a bit. Any tips on this step?

Your best bet would be to support the pipe from the opposite side somehow and then use a small center-punch where you want to drill. Good-luck.

Q:okay, well, I understand partials. But, on a trumpet, what does each valve do? I mean, I had this idea that each one was a half-step up from the previous...but that's not true. Is there some sort of pattern to them? Does each one have a different purpose?...Please answer as basically as possible. I don't play music very often, and I definitely don't speak brass-ish.

Each valve kicks in that pipe that comes out of it and makes the instrument longer... and lower sounding. #1=1step, #2= 1/2 step, #3= 1 and 1/2 steps. Just add them up to see what the combinations do. Each time you lower it you get another overtone series to play up or down on.

Q:my EGR valve has gone on my Vauxhall Vectra 2.0 DI LS, 1998, 5 DOOR HATCHBACK, so i am getting a new one next week, what i want to know is, is it an easy job to replace them if so how do i do it? or is it better just to let a garage do the job?

The EGR on this model is indeed vacuum operated. The diaphragm rarely fails to be fair but that particular engine suffers with vacuum leaks. This is something that needs checking first. Also, before buying one, try sucking on the little vacuum connection going into the unit first. You should feel resistance as the plunger is sucked up against spring pressure. If no resistance is met, the diaphragm is gone and it needs replacing. If you can feel the plunger lifting, there is nothing wrong with it. You can remove it to make it easier. Push the plunger in by hand and put your finger over the vacuum connection; the plunger should stay where it is until you take your finger off. (It's hidden under the plastic cover on the top of the engine (3 Torx bolts) and is easy to access.) The EGR valve unfortunately comes with the inlet manifold (expensive) which would mean removing injector pipes etc. if you fit it all. It is, however, very easy to replace if you just remove the 2 bolts holding it into the inlet manifold. They are female Torx but an 8mm 6 point socket will work too. Any other questions on this job, just ask or email.

Q:where is the shuttle valve located in 03 land rover discovery hse ?

The shuttle valve is a part of the brake modulator this problem is addressed by the replacement of the brake modulator and that's a $1,500.00 dollar part plus labor but I believe that they sell a shuttle valve repair kit for around $100.00 dollars.....

Q:Alright. The engine is a 7mgte. The clearances for the skims in the intake side is 0.20mm and the exh side is 0.25mm. What happens if i mixed the shims?

It does make a difference on which shim goes where! Make sure pushrods are in the right place, i'm not sure on that type of engine but some engines have different lengths for pushrods intake could be different length than exhaust! You could also have a bad lifter.
