- Q: I have a 66' malibu el camino with a 283 sbc and a powerglide transmission! I have bee noticing a ticking noise on the motor and it miss kind at a rhythm. I took the valve covers off and noticed pieces of metal right by the front of the motor on the head. It is where the #1 piston is. Some of them have kind of a rounded off shape to them. I dont see anything wrong with the springs. but its dark and i cant really see. I also noticed on the even side 2/4/6/8 some of the rocker arms are loose? Some may be loose on the odd side too. not sure, i didnt check them. I found them right where the hole is where im guessing where the oil comes in. What do yall think? It idles kind of rough and i have noticed a loss of power? do i have broken valve springs or something? Thanks for the answers!!!!

- Q: I wanna do it myself My dad knows how But i must buy the parts I have a rmz250 and i was wondering if u can jus buy valves and seals and jus put them in without grinding since the seals are new i heard u must gring the seals to get the valves to sit flush againt the metal serface but cant u jus buy new seals and retainers and put that in plus the valves and ur done?
- you *can* just put the valves seals in and run it but it is NOT recommended. If you want the best seal which will = the most power, the valve seats need to be cut. If your not running a titanium intake you could get away with just lapping the valves with course and then fine lapping compound. I know a lot of people who just lap them in, but the most professional way with the best results is to cut the seats.
- Q: Exhaust valve opening (EVO)Intake valve opening (IVO)
- HI You answered it your self... exhaust valve opening (EVO) is when the exhaust valve opens.. and the same for the intake (IVO).. When the EVO happens the motor pushes the exhaust (burnt fuel) out of the motor when the IVO happens it sucks gas into the motor to get burned and make power.. Exampe of a 4 strock motor. 1) piston goes down , sucking in air and fuel (IVO) 2) piston goes up compressing the air and fuel spark plug fires ignighting the fuel 3) piston goes down turning the crank powering the car from the explosion of Fuel. 4) piston goes back up pushing the spent fuel out. (EVO) then repeats. On a 4 cylinder car this happens 4 different times on an 8 cylinder car 8 different times and on 6 cylinder car 6 different times. When one cylender is firing another well be coming up to push out its spent fuel and another well be going down drawing in fuel and so forth.. good luck tim EDIT IVC = intake valve closes EVC= exhaust valve closes
- Q: So I know the main purpose of the EGR valve is to recirculate some exhaust to the cylinders to reduce NOx emissions. However, a mechanic told me that a malfunctioning EGR valve can make the engine run way hotter, and that this can damage the pistons, or other components of the engine, over time. Is that true?
- Yes. An EGR valve reintroduces exhaust gas to cool the combustion chamber, making it run cooler, due to less oxygen. Oxygen burns hotter than fuel. So if you have a faulty egr valve, emissions will go up, and you run the risk of overheating and damaging the engine. It could cause the pistons to expand, or seize, due to higher temperatures. It was not as much of an issue in yesterdays cars, because they had much lower compression. Now tolerances are tighter, but metallurgy is also much better. It still does run the risk of running hot, and causing predetonation, which would destroy pistons and other engine components such as the crankshaft, and valves.
- Q: What are the function of reed valves on a motorcycle?
- They allow a fuel/air mixture to enter the area under the piston in a two stroke engine on the compression stroke, as it is a one way valve when the piston is coming back down the gases are forced up through the tranfer ports into the combustion chamber.
- Q: I need to make a ball valve that will open with no manual force but by a motor of some sort to spin it and release water. how do i make a ball valve controlled by preferably a motor or other CHEAP device. I need to do this for less that 20$
- It's a lot easier and cheaper to buy the valve at a hardware store than make it. You can probably get a motor and gear train from a hobby store. If it doesn't absolutely have to be a ball valve, you can get electric sprinkler valves from just about any home and garden supply. They're specifically designed to control water flow. Just hook it up to a power source and you're good to go. Addition: Just remembered, you can also get battery operated water control valves that connect between a faucet and a hose. I'm pretty sure they're ball valves internally. Prices vary, so shop around. Depending on how fancy you want it to be, they go for about $5.00 and up.
- Q: I jsut got my valve cover replaced on my car what does that do?
- Usually only the valve cover gasket needs to be replaced (unless you somehow damaged the valve cover itself). It does just what it says. It is the metal(2) located on the top of you engine that covers the valves. It needs to be replaced when the seals are allowing oil to come out.
- Q: here's some additional info asking of my question...I plan on buy a BLOWOFF VALVE and woundering where does the BLOWOFF VALVE goes in my car or do i have to replace with stock EGR VALVE using same hoses or help me please don't wanna screw this one up
- Only TURBO engines have blow off valves. It protects the engine from over charging from high turbo charged ar pressure. If your is bad, it means that the diaphragm inside has ruptures. Many times there are repair kits with NEW diaphragm parts. LEARN form this. Only SYNTHETIC OILS that canhandle high temperatures can be used in your car. VALVOLINE will destroy your turbo bearings and blow youblowoff valve. Use Mobil One, Pentosin, or AMSOIL in there. THese oils can handlee the heat with NO breakdown, NO coke build=up, and NO oil feed or return line failure. STAy AWAY from wax based conventional engine oils. They are NO GOOD for your application if you haVE A blow off VALVE!!!!
- Q: how hard is it to clean the egr valve on my 2002 Chevy Malibu? if you can give step by step or possibly a website/YouTube video link. thanks
- Cleaning it could make it worse then your experiencing now, but if you want to here's the steps. There are two bolts holding the EGR val;ve down. Remove them, and use a can of carb cleaner to clean the carbon out of the two ports that are in the valve. Reinstall with a new gasket and run the car. If the check engine light comes on replace it. I recently got a EGR valve (not recommended but they work) from a local wrecking yard for my folks '99 Venture 3.4 ltr motor, replaced the one on the van because it was throwing the EGR code and it worked fine. No more check engine light.
