- Q:I'm thinking of buying a used 2006 Volkswagen Jetta. It has a 1.5 liter 20 valve engine, and I really don't know what that means. That's good, right?And is this a good used car to buy?
- Most okorder , and check the service records for the car you are interested in buying.
- Q:What is the purpose of the LNG Vs Propane Valve that has to be installed on Gas Stoves/Ovens before use ? How can I set it myself for Propane ? What negligible effects would I experience if I hook a stove up to Propane while the valve is set-up for LNG ?Thank You !
- LP gas and natural gas work off of two different pressures. Usually there will be a inner spring that need to be changed out inside the valve, and the orifice will need to be changed as well. If you don't convert your valve, it can prove to be very dangerous! Most likely it will only have an erratic flame, and burn very dirty. The flame will burn out of control and have orange color to it. However, it could result in not burning off all of the gases as they are released, and could cause an explosion. Most of the time in the owners manual it will have step by step instructions on converting LP to Nat, or vise versa. Remember, gas is a safe alternative to electricity, but if not handled correctly it can be very dangerous. Please proceed with care, or if you are uncertain with yourself, call a qualified technician. It shouldn't take em more than an hour, and most techs charge around 60 bucks an hour. A cheap price for a job done safely.
- Q:What would be the effect on valve opening if the clearance was set too large or too small, please help
- If the clearance was too big, the valve will not open or only open slightly and your engine will suffer. Too small and the valve will make a ticking noise everytime and will open your valve too soon. You have to set the clearance according to the manufacturer recommendations.

- Q:I want to put a blow off valve in my car to make it sound cool lol but i dont have a turbo yet ... do i even need one?
- Buy a compressed air tank that you can fill at a gas station like you would air up a tire. Mount this tank in your trunk and route air hose from the trunk through the passenger compartment and into the engine compartment. Add a simple valve in your center console or wherever you prefer to turn the air on or off. Drill a hole though your hood and affix the air hose to it. With the air tank filled up, just open the valve and WHOOSH, instant blow off valve sound. You could even fill the hose with confetti for a colorful display. If you wanted to get real fancy you could rig up an electric air compressor under your hood for a continuous air supply. Thats the only way you cant get the release of compressed air to make a blow off valve sound without a turbo. Oh, and while you buying all the supplies for this don't forget to get some fake spinner bling-bling hub caps!! Then you will have the ultimate pimped out ride!
- Q:Where do I get a electric valve with a 120 VAC coil
- Cheapest okorder /... Grainger being a major supplier of parts - note the high cost of many of these because of being high temp steam and hot water under pressure and look for other choices.

- Q:I've been working on cars since around march of 2012. I new. I have a set of 305 heads that were really dirty. It came from a 79 camaro that never had an Oil change. I took the valves out and the valves are pretty burnt. I was wondering If I cleaned them up would they still be good to use? The edges aren't rough or anything. Just let me know what is need to know please. The heads I know are still good.
- Any automotive machine shop can inspect the face and straightness if the valves to see if they can be re-ground and re-used.
- Q:Dr says I have a leake heart valve. Should I be concerned?? He doesn't think so but I am worried. Should I get a second opinion? I am 53 and a diabetic. Has any one ever had this problem?
- i've got had this very comparable concern 4 yrs. in the past, which grew to become into actual got here across 20 yrs in the past. If the back pass of blood in the mitral valve is extreme and the midsection starts off to amplify, then the only ingredient which would be performed is a valve replace, which i did and stay an exceedingly regular existence now. look ahead to fatigue, dizziness and shortness of breath. If those issues ensue frequently, make an appointment along with her heart expert at modern.
