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:I was woundering if anyone had a repair manual for this valve on a 2004 Nissan Maxima. I just bought the car and Im getting the P1800 Code. Any help would be appreciated!: 2004 Nissan Maxima Manual

Q:How do you repack an osy valve? Where do you get the packing from? Do you have to shut down the water to do it?: where is i get the packing gland material

Q:I just bought my first bike in 20 years, and as a result have had to pump up a bike tire for the first time in 20 years. I was dazzled to discover a type of tire valve that I'd never known about. The Presta.So of course, I need a pump with a special adapter, I didn't know to unscrew that nut at first so I accomplished a whole lot of nothing for awhile, and once I did open the nut, the pump kept slipping off the tire once I got anywhere near the tire' recomended PSI until I awkwardly held it in place while operating my pump with one hand, which of course meant less leverage and so while I got above the min recommended PSI, I couldn't get anywhere near the upper end of the spectrum. Why would anyone use these ridiculous contraptions? The fact that they are used means there must be some rationale. A brief internet search seems to find more forum posts with people saying the alternative (Schraeder) valves are more reliable and don't leak as much either.Educate me!: I've never had any problems with presta valves. I suppose their only advantage is that they can be fitted on ultra thin rims.

Q:Ok, I recent rebuilt a set of vortec heads, but the valves I got are a bit longer than stock, I believe .1 competition products pn I2552P. I also installed howards cam 98214 springs with 10° locks and retainers, the locks are +.035. I was just wondering if I would have enough spring pressure.: Get okorder

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: In 95 plus percent of cases so-called mitral valve prolapse is a normal variant. If yours was other than a normal variant your cardiologist should have discussed this with you. As such I would not worry. JR

Q:My 99 accord has been smoking bluish white smoke out of the exhaust only at high RPMS- 5000 and up, but NOT at lower RPMS. Obviously I rarely go that high, but I've feared the worst. I've checked the coolant, its green without contamination. today a mechanic discovered that someone installed the wrong pcv valve on the car- the one that belongs on the v6 model, and that it is somehow larger. the mechanic suggested it was possible that this was the cause of the smoke- the oil was getting into the intake manfold, and into the cat, and that when the engine is at higher rpms, and the gases/ heat increase, it burns up the oil in the manifold/cat. He said IF that is the cause it should clear up in a week or so. Does this sound to good to be true? or is it possible? the car does have 160,000 on it, but i've owned several hondas with much more mileage that didn't smoke at all.: a stuck PCV valve will cause oil burning too.....so that is a good place to start.

Q:When using seafoam through the PCV valve. Which side contains the vacuum? From the crank case of intake manifold? The brake booster line is very difficult to access and on their site it says I can apply seafoam through the pcv valve.: The PCV valve scavenges OIL VAPORS from the crankcase tthe VALVE COVER. Remove it and you will FEEL the vacuum when you put your thumb over it. It will POP the small pellet inside it. Foolow up with GUMOUT srpay and use BOTH to clean the THROTTLE BODY and the IDLE AIR CONTROL VALVE, the IAC is resonsible for mixing AIR with injecte4d fuel. A dirty IAC will RUIN mileage and clog up the converter. GOOD LUCK!!!

Q:the valve stem?: you cant get used one out and re-use it they tear up when you remove them unless their the ones with the nuts on them that bolt in,pull in types cant be re-used ,any parts store sells those in a pack of 4 or most tire shops will give you one if you ask them for it,good luck

Q:Hi. I looked at instructional videos for installing shutoff valves and instead of simply unscrewing old valve, the plumber simply cut the copper pipe. Is this necessary? Why can't I simply unscrew old shutoff valves from copper pipe?: Shutoff valves come in two varieties. 1. A compression fitting and looks like it is bolted onto the pipe. 2. Is soldered onto the copper pipe at each end of the tap. If you are paying your plumber by the hour, believe me, you will want him in and out including travel time in under an hour. If cutting the copper is and would be his quickest way then let him have at it. Good Luck Richard
