- Q: I am working on my riding mower Briggs and Stratton 15.5 OHV. After replacing my headgasket my intake valve did not move when I turned shaft by hand. I took it back apart and believe I have my pushrods positioned correctly but cannot seem to get the rockkers back over the valves and rods. Maybe its because I am a girl and just need to man up but I thought it should be easier. Anyone got any tips?
- Panic? run around in circles? I have no thought what you prefer to do. yet in case you have been thinking, wanna comprehend how a lot of those little plastic rings that protection seal the bottle caps to the oil bottles i've got discovered under the valve cover? we could basically say lots, did they harm something? no, they only take a seat there, as there too great to pass down the oil galley and in the event that they have been that they had take a seat interior the backside of the oil pan or get caught to the oil pump %. up show screen, i'd desire to pass on approximately issues i've got discovered sitting in oil pans and caught to the show screen yet I wont, yet little products of RTV are on the ideal of the record, and if the show screen misses it your oil filter out won't.
- Q: I have a 1989 Jeep Cherokee with 218,700 miles on it and my engine has thick oily gunk on it, possibly from a leaky valve cover gasket, should I change the gasket? I have been told that this is normal and not to worry about, but from the amount of this gunk, I find it hard to believe this is normal. The top of the valve cover has a light covering of gunk, but on the sides and towards the bottom of the engine. it gets very thick and at some places you can't even make out whats suppose there. Does a leaky valve cover gasket mean that there is another problem going on?Can leaving the oily gunk on the engine cause any problems?Any info would be greatly appreciated.
- Usually, a leaky valve cover gasket is just that. A leaky valve cover gasket. Unless you are building up high internal pressure from a clogged PCV for example and literally forcing the oil out the weakest point, there usually is no underlying issue. Leaving the oily gunk does a couple things. If its on rubber such as any hoses that aren't oil resistant, they will degrade quickly. The same can goes for wiring insulation, motor mounts, or even the rubber seals on some of your front end pieces. Also, wrapping an engine in a thick layer of goo doesn't let it cool as it should and puts more thermal burden on it. What you do at this point is a question of how much longer a 1989 Jeep with 218,700 miles will go or how much longer you want to keep it.
- Q: 2003 Ford Focus SE2.0L SPI EngineAutomatic Transmission 145KPerfectly maintained since new!One of the pistons had snapped, yes the actual piston, it didn't mess up the walls, but I am hearing a LOT about these dropping valve seatsI intended to do an entire rebuild with a kit, but did it break BECAUSE of a droppedvalve seat?I don't know because I don't know what that isHelp is appreciated
- Valve seat is the actual area on the head that the valve rests in when closed. Dropping a valve normally means that the keepers have come loose or a spring has broken and the valve has dropped into the cylinder. This was a common occurance when some one has modified an engine without upgrading the valve train especially in older engines.
- Q: I have a 2004 rmz 250 i was wondering if i could get some specific details on how to adjust and the spec's for the intake valves... thanks
- Buy a manual for your bike. The question is far too broad to be answered here due to the complex nature of a modern valve train, like found on your RMZ. It involves removing the intake and exhaust camshafts to gain access to the shims underneath the buckets on top of the valves. You must know where to time the cams again in relation to the crank otherwise, it is very possible to destroy your engine if not installed properly...Hence the advice on obtaining a quality service manual beforehand... It's also why the shops charge a seemingly extortionate amount.
- 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: Ok guys I have a 70 4 bolt main 350 40 over. I have a lunati 292 cam 230 at 50 degrees. 480 lift. The kit says 1.5 rocker ratio. No valve adjustments needed. I just boight edelbrock aluminum heads summit number 5089 64 cc with 185 intake runner . And comp cam roller tip rockers. That say 1.52 ratio. All my decks on the engine and heads are stock not shaven. I have speed pro pistons with .125 dome. Im using standard felpro gaskets. Ok my question is will standard lenght pushrods work for this build. They are 7.794 length. And will my piston head clearance be ok cause of my domed pistons. and do I need to find rockers that just say 1.5 ratio to make this work or are 1.52 the same. Thanks
- Your fine with the roller tip 1.52's
- Q: Mitral valve prolapse have impression on lifetime?please answer with source
- Mitral valve prolapse (MVP) is the most common heart defect in population. The prevalence of MVP is about 0.6–2.5%. The occurrence increases with age, and the highest is in young woman. MVP is diagnosed by transthoracic echocardiography when displacement of mitral valve leaflet(s) above the annulus into the left atrium during a systole is present (Fig. 1). The clinical symptoms of the disease are connected with instability of the autonomic nervous system. Fig. 1 Two-dimensional echocardiographic long axis parasternal view of mitral valve prolapse. MV mitral valve, LV left ventricle, LA left atrium, RV right ventricle, Ao aorta Such a large population of patients becomes a problem of social significance, and it is extremely important to determine the influence of MVP as a chronic disease on patients. That is why our trial to evaluate the health-related quality of life (HRQOL) in children with MVP was undertaken. There are many publications concerning MVP in adult patients, but no study on their quality of life has been found. The literature concerning HRQOL of children with heart defects is not very extensive; the authors analyzed the problem of patients with serious conditions, such as hypoplastic left heart syndrome, transposition of the great arteries, pulmonary atresia, tetralogy of Fallot and non-complex heart defects, like ventricular or atrial septal defect [1–3]. The aim of our study was to evaluate the quality of life of children with MVP and the impact of clinical symptoms on HRQOL. You will detailed information on the link given in sources, as it is long topic.
- 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!

- Q: i need exhaust valves material dimensinons of any car.
- Most valves are made of forged steel. The dimensions depend on what car. You can get a factory manual for any car. Call a motor shop to order them. Don't try to make them yourself.
- Q: this question was on my test for APII, the question is stated as:the tricuspid valve is closed...a) during rapid filling of the ventricles (this is the answer the teacher shows to be correct)b) by contraction of the papillary musclesc) while the atria contractd) during ventricular contraction (this is the answer i chose i got it wrong)please let me know to correct answer!! thanks!!
- The bicuspid valve is the left atrioventricular valve, and the tricuspid valve is the right atrioventricular valve. Blood enters the heart via the Superior Vena Cava (and Inferior Vena Cava) into the Right Atrium. In between the Right Ventricle and the Right Atrium is the Tricuspid Valve. The right ventricle receives oxygenated blood from the right atrium (as it contracts). Once the ventricles are full, they contract and the tricuspid valve shuts and the pulmonary valve opens. This makes sense for the tricuspid valve to shut (preventing regurgitation or backwash) while the blood flows through the open pulmonary valve into the pulmonary artery (to the lungs.) I would not have chosen a) or c) for an answer. You can rule out b) for an answer because the papillary muscles contract opening the tricuspid valve. You chose the correct answer, d) because once the ventricles are full they contract causing their respective valves to shut.
