Q:I have a road bike that has schrader valve tubes and my current tire is rated to 90 psi max. I ordered some new tires that are 100 to 120 psi max. Will the schrader valve tube hold that kind of psi? I dont really want to buy converters and new tubes right now.
Yes they will hold.
Q:I have a 3406b motor. It has blow by. This happened when I hired a mechenic to do a top end. I belive that he did not ajust the valves correctly or something happen to the motor. I want to gap the valves to see if this helps out. How would I go on doing this.
try using this link here to help you out. Dont know if you have engine brake or not. but u should be able to still adjust the valves correctly if you follow along with the process.
Q:It's just a small 1 cylinder 1000 watt generator but thanks to contributors here, I verified the exhaust valve is pitted after I cleaned it all up with oven cleaner a toothbrush. My question is can I just replace the valve itself or do I need an entire new head? The seats still feel smooth.
There is no need to replace head if the seat is good. Blue smoke indicates to rich a fuel mixture,white indicates oil consumption.
Q:my mid eighties GM full size car with a 305 just started to have a problem...it runs fine at idle.....runs rough/sluggish at speed......when I take my foot off the gas there is a fast rattle in the engine.........and sometimes the engine likes to idle fast.....I replaced the catalytic converter last year ...........so now I am thinking of changing the egr valve....there is no service engine soon light on and this car is a mid eighties so no obd 2 system on this car......any other ideas? thanks
EGR valve got sooty,and rusty and dirty and then they dont work right. They either dont open or they get stuck open and cause the car to run lousey. If the valve has been i the car since the 80's it is probably about time to either clean it or change it. do you have haynes or chilton manual for the car? they explain alot.
Q:im having trouble locating the pcv valve on my 1979 oldsmobile. i have a 305 engine. i need to replace it asap, so any help would be appreciated. thanks in advance to all feedback.
Facing the engine, should be on your left valve cover. Has a hose attached to it and sticks into the valve cover.
Q:I bought my first car recently. but it has a high idle and smoking problem, i already replaced the spark plugs. I've been reading about the exhaust gas re-circulation valve. but i cant find it. where exactly is the EGR valve located in a 1999 KIA Pride?
all EGR valves should ( unless a very odd engine) on exhaust manifold. they will have a tube outlet returning back to inlet manifold and a control mechanism on it ( electrical connection) . these valves are known to carbon up and fail both due to soot.heat .wear etc. very possible this is the problem. a temporary fix can occasionally be found by soaking over night in cleaning fluid such as easing oil or petrol etc and washing out but this sort of fix never lasts. be aware these valves are not cheap.
Q:Sohc ZC (d15) honda I'm going to be painting my valve cover am I going to need new seals? What do I need to take it off and put it back on ? Please help I have the high temp sand paper all ready to go I just want to be ready
if i were you i would replace the gasket ! even if it don,t break taking it off it,s best to put a new gasket on when you pull the valve pan !
Q:I know absolutely nothing about cars. My AC stopped working, I had a new air compressor, drier, expansion valve put on. It was also vacuumed out. Problem is it will not take a recharge, and there is no refrigerant in it at all. But it keeps reading high pressure, I don't know the readings I was told it is reading high, and will not take a recharge. Someone on yahoo answers suggested it might be the Schrader valve is this a problem that it can cause if it's bad that it will not let you recharge, and read a high pressure reading? Is there a Schrader valve for the low pressure valve amp; the high pressure valve or is there just one? I have a 96 Dodge Stratus ES. Thank you for any help or ideas.
2 valve 1 low 1 high the valve is cheap (looks like the same as one that goes in a bicycle innertube) but if a shop puts it the labor price for your area, here around 75.00 this dont make sense. to have high pressure there has to be something in the lines. and the valve would be open to give you a reading so unless its leaking its working. with a vac on it and 0 134a you should have a reading of -20(+or-) in of mercury on the low side (below 0) and 0 on the high side. If the high side valve was not depressed (opened) then you would have the can pressure reading (about 80psi depend on temp) only if you tried to fill from the high side. Ok try this find the line going to the firewall and inside the car, this is the low (return) line. dont use the one that goes to condenser at the front of the car (the radiator looking one). find the fill valve and thread on the fitting (may have a cap on it) tighten the fitting until it is tight then use a pair of pliers and turn 1/8-1/4 turn more then try to fill.
Q:Some trombones have Thayer valves? What are those for compaired to the regular standard open wraps?
open wrap is a design for less backpressure through the valve,....the thayer valve reduces that backpressure even more. go play different pro horns side by side, vary the brand/valve combinations and see what plays the most free (especially in the low to pedal range).personally i play an old bach 42k and i love it.
Q:Could I get some possible remedies for Mitral Valve Prolapse pain? I currently am off beta blockers, and I need to cope with the mild, moderate to severe chest pain I experience. Female, average weight for my height, nonsmoker, maybe one alcoholic drink a week, exercise at least 3.5 hours a week. What do others with mitral valve prolapse do that helps?
Beta blockers are effective in reducing the chest pain related to the mitral valve prolapse syndrome and there are some other lifestyle modification that you can do to help improve your symptoms. It is important though that you be evaluated by your doctor (which I am sure you have) to determine if this chest pain is truly related to the mitral valve prolapse and not some other cause of chest pain. Other causes of chest pain include musculoskeletal, anxiety, heartburn, etc. The treatment for these other causes of chest pain would be different than that for MVP and this is why it is important to determine the exact cause. The lifestyle modification that has been found to be effective for MVP symptoms like chest pain includes aerobic exercise training, the avoidance of stimulants (caffeine), alcohol and undue fatigue, and a reduction in stress. Regular aerobic exercise in people with symptomatic MVP was associated with decreased anxiety, increase general well-being, and a decrease in the frequency of chest pain, fatigue, and dizziness. Magnesium supplementation to individuals who are deficient in Magnesium and have symptomatic MVP was also associated with improvement in symptoms. Magnesium levels can be tested on simple blood tests to determine if you are deficient.
