Q:I have a honda civic and i took it to get an oil change and they told me that i had an oil leak because my valve cover needed replacing. I did not let them do the work. I called my personal mechanic and he's out of commission for a little while, so he referred me to a friend of his. He said he cleaned all of the built up oil and replaced the valve cover. I noticed yesterday that my car looks like it is leaking oil really bad. I'm wondering, could this be from him washing the old oil that was leaking? My belts seem to be squeaking, like they do when it rains. Any ideas? could this just be excess water that he cleaned it out with?
To determine If the valve cover-gasket is leaking again, take the car to a wand-type car wash. Shut the motor off, open the hood and thoroughly wash the engine and compartment down with hot water and soap. Concentrate on the valve cover itself and the mating surface between the valve cover and cylinder head. Rinse with hot water spray. This is the only way to clean-up the previous mess so everything will be dry and clean. Use a flash-light if you have one to inspect all the way around the lip of the valve cover to look for any bright, shiny oil that could be leaking again after a short drive. Having been cleaning engine compartments for 45 years at car washes, don't worry about electrical connections, cracking or breaking anything. There are quite a few tricks to make valve covers seal properly. To start with the cylinder head has to be clean and dry, the valve cover had to be clean, *flat and dry and use only premium Felpro, silicone impregnated valve cover gaskets.
Q:My car (RWD) has vacuum leak and has the code PO171/PO174. I find some engine oil at the bolt well of the valve cover on the bank 2 side. Can the vacuum leak come from the valve cover? What is the main function of the valve cover? Thanks.
get a new p.c.v. vale . and in air cleaner is a a small filter that hose clips to . .most imporent is pcv vale is working and this will stop
Q:I have a curtis toledo compressor at my house. While moving it a helper dropped it on its side into the tank and broke off these 2 valves off the very top of the compressor. They had a copper line that ran off both of them and went over to the auto on/off switch, I'm guessing that's what it is. Where can I buy these or at least what are they called?
They are the unloader valves. Look online for places that sell parts for air compressors.
Q:My grandfather is going in for a valve replacement.. and I'm really worried about him.. I just want some information.. any good websites if you have them.. I looked on google.. But if you have any good ones that would be great..No horrible comments please..
sorry okorder
Q:I am doing a big project on Valve and it's games. I am currently doing some research on the company and wanted to see if anyone had any interesting facts or information about Valve that may be useful when doing research, thank you. :)
Valve = Steam. Research Steam and you research Valve.
Q:Hi all, I found oil leakage in my distributor and am about to change the o rings. however, i feel that a blocked PCV valve is causing the pressure to push oil into the distributor. I have been searching for the PCV valve. Can someone please tell me where it is?
The PCV valve is located beneath the intake manifold on the right (passenger) side. It threads into the breather seperator and points toward the center of the car. To remove it, you'll have to remove the Idle Air Control valve located on the end of the manifold log. Be aware that you'll have to do at least part of this task underneath the car, and that the IAC valve has antifreeze circulating through it Get a mechanic to do it if you can afford it
Q:where is the fuel tank selector valve located on the truck?
There is no selector valve on 1992-95 F150's. There were or the older carbureted trucks but newer ones are all fuel injected and have in-tank fuel pumps. The switch on the dash just selects which pump you turn on. I'd say the front tank fuel pump has gone bad or possibly has a cheaper electrical problem (if you're lucky). Exact same thing happened to my 1995 F150. Replacing a pump is a pain and not cheap.
Q:I know nothing about toliets - so please bare with me. The water valve underneath my toliet is dripping and I have to turn off the water in order for it to stop. It's really annoying to have to turn the water on when I want to flush it and have to empty out the container that is catching all the time. I think it has something to do with the valve itself and I'm PRETTY sure something behind it needs to be tightened - Has this happened to anyone else? What did you do?
You can usually see the water coming out between the packing nut and stem. If it is not the packing nut, sometimes water will trickle down from the connection at the commode and appear to be leaking from the valve. Both leaks will stop when you turn the valve off.
Q:This happens when the sprinklers are ON and goes on for a minute after the sprinklers go off. Should I replace the whole valve or do I need to check the diaphram or solenoid head? In addition to leaking, I have noticed a more potential problem - water hammer. As soon as the sprinkler goes off, I hear this loud banging noise from the pipes underground. Water pressure is fine ~ 50. My guess is air inside the pipes is causing this. Is this because of faulty valve which is leaking?Also, any difference between the valves that are sold in Lowe's and Home Depot to that of commercial valve? My lawn guy says commercial valves last a long time.
I have been given the equivalent line from our water application whilst the stress valve broke and blew up our water softener it rather is the 1st element on the line from their tension regulator. luckily, it has a life-time insurance yet their plumber instructed me that it extremely was once the accountability city on the grounds that of the stress regulator which they admitted to being at fault whilst they replaced it.
Q:Around the relief valve there is water leaking it is not the valve it's self or the threads it's around the out side of it. The valve is on top of the heater
If you are sure the valve is ok, it could very well be just condensate. Other than that, the tank itself could be leaking internally and this is the shortest point for it to show up. If this is the case then there should be water in the floor as well. I would replace the valve first as there could be a small crack in the valve body that only shows up under pressure.
