- Q:The time has come to re shim my 06 450, and I am having a small problem (I think anyway). The exhaust valves have decreased to below the required spec and need to be replaced with thinner shims (as is usually the case), but the left intake valve has for some reason increased its valve clearance (from 0.16mm to 0.23mm). Is it normal for the valve clearance to increase? I thought they would only decrease... Any ideas? Unless the valve is being held open by something. Many thanks, Jim
- The valve seats in the head take a constant pounding when the valves close - causing the valves to move up into the head and tighten the valve clearance. Carbon build up on the valve seats and valves will hold the valves open a fraction (unnoticeable in the engine's performance) - which will loosen the clearance.
- Q:1990 Pontiac Sunbird, I took a piece of hose going to the egr valve to try and see if it is working properly, but with car off, I can suck through, and blow out into hose going to egr valve, and it doesn't seem like there's any seal stopping air flow either way...is it supposed to, or what is this supposed to do?
- The okorder /
- Q:its rated 120 VAC/26VA (3 prongs, one for ground) . I also have a horizontal level switch for liquid with rating 120 VAC/0.28 A (the switch will connect when the water level reach the target) normally open.How can I wire them so that when the level reached the valve will close and water will not flow into the tank? The switch is inside the tank and the valve connecting the pipe for feed water. Thanks

- Q:So just yesterday i bought a second-hand ytr 2320e. After i bought it, i washed it and tryed playing it, but when i press the first valve, there is this small metal scraping metal sound kinda like if you scratch a metal bowl with a fork. I think it has something to do with the spring but im not sure.also, i was wondering if the trumpet valves are supposed to be very easy to press, or if they take a tiny bit of push.
- I don't think anyone knows, because there's multiple Bibles. And people interpret it their own way, and re-print it with different scriptures. As far as I'm concerned, there is no such thing as a REAL bible anymore. And any beliefs we have today about it are all false. According to one bible, you will be sent to hell on both counts. According to a modern version, you will be excused for doing your wife, and in another bible, you'll be stonned for asking this question (Knowledge is a sin) Interesting that we are the only intelligent life on earth, supposedly made in God's image, and yet the bible says to stay away from the tree of knowledge. Sorry, I don't buy into that bullcrap.
- Q:I Have a 2001 Honda Accord 3.0 V6. Would a clogged EGR valve cause it to run rough and have problems starting up when it is warm? It also runs hot. I have replaced the thermostat and the cooling fan relay? What could cause all of this? PLEASE HELP!
- Ok, the computer did NOT say to change the egr valve. Post what the code number was. It may be a bad wire, faulty egr solenoid, plugged egr passage, bad DTFE sensor, broken vacuum line, etc, etc. There are tests that a real mechanic (not a parts salesman) can run to determine what the real problem is.
- Q:When I went to cardiologist he said i had normal EKG, excellent blood work high HDl 58, low triglycerides only 51, and LDL was like 71, ejection fraction of 65% he said I was fine but he said I had mild mitral valve prolapse. DO I have to worry abt the mitral valve prolapse? Im healthy and can I live a normal long life any opinions?I dont smoke, dont do drugs, no family history of Heart problems just some cholesterol but mine is low so Im good
- If it is MILD mitral valve prolapse then no you don't need to worry. Most likely what your doctor meant is that you have a mild heart murmur which is not dangerous(that is only a guess since i don't know exactally what your doctor said and am not physic). If there had been dangerous or to worry about you doctor would have told you and explained the issue. Why didn't you ask him about it when he told you? Here is some information about this topic ?Mitral valve prolapse (mitral valve prolapse) is the most common heart valve abnormality. ?Most patients with mitral valve prolapse have no symptoms and require no treatment. ?Mitral valve prolapse can be associated with fatigue and/or palpitations. ?Mitral valve prolapse can often be detected by a doctor during examination of the heart. mitral valve prolapse can be confirmed with an echocardiogram. ?Patients with mitral valve prolapse are usually given antibiotics prior to any procedure which might introduce bacteria into the bloodstream, including dental work and minor surgery If you are concerned then go and talk to your doctor about it more. Your doctor is a professional and should be the one to explain it to you. I am not a doctor, nurse or cardioligist all my information comes from Personal Experience and Research.
- Q:i ha valveve a knock on the driver side .and i have to remove the intake manafold to get to the valve
- Really? I find that innane. rocker covers usually come off pretty easy, and are well above the manifold-unless its a sidevalve???
- 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.
