- Q:In the very near future I'm having valve replacement surgery. I haven't yet been told the risks or the recovery period, does anyone know the risks or the recovery stages and how long recovery takes?
- Valve replacements actually have very low morality rates like 1-2%. There are always risk's with surgery though, such as blood clots or irregular heart rate. The recovery in the hospital is generally 5-7 days, and then it can take anywhere from 8 weeks to a year to feel recovered.
- Q:My furnace cut out about a year ago. The hvac guy i used told me the gas valve was no good and that the flu was partially blocked. I cleaned out the flu, he replaced the gas valve ($700+) and it worked great for a year. Today the furnace does not fire up. Pilot is working. I cleaned out the flu (there was definitely quite a bit of debris, so that was probably the cause for the shut off) .... The flu is now clear, but when i turn the system back on the thermostat calls for heat, but there is no gas flow to the burner... could the valve have failed that quick, or should i be looking at something else like the CO sensor or something... just looking for some direction before shelling out another 700 bucks... Thanks in advance for any ideas or assistance....
- I was wondering why the flue is clogged? I've never had to clean mine. Well anyway, I use a shop vac to vacuum out any dust or rust that accumulates on the gas valve on the rare occasions it failed to work,and that fixed it every time.
- Q:im looking for the egr valve on a 97 mazda 626 its not in top of engine like other cars where can it be?????o and its a 4 cylinder
- You egr valve will be located on the exhaust or have a metal tube running from the exhaust the other side of it will be mounted on or near the intake. you can also look at the vacuum routing label on the hood if it is vaccum controlled it will be listed on the diagram
- 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: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.
- I would be worried more about your geometry right now than spring pressure. Your saying the valves are .1 longer? Thats quite a bit.
- Q:I am trying to repalce the water turnoof valve under my sink but the valve just keeps turning and no progress is made to get it off so I can put on a new one. I am turning it clockwise but it just keeps turning. Can someone please tell me how to get this off? I do not want to have to call a plumber for something that I might be able to fix myself.Thanks.Sandy
- Off is counter-clockwise. If it cannot be turned off, then you will have to find the main shutoff for the house. Shut down all the water. consider putting in copper pipe to cpvc shutoffs...they don't rust or corrode. 1/4 turn ball valve.
- Q:My eight month old daughter was just diagnosed with pulmonary valve stenosis. Anyone have an experience with this? Did you have cardiac catherization? Did that fix the problem?
- I had a different heart condition in high school. Mine was called superventricular tachicardia (SVT) but it required a cathedar in my heart. I had the ablasian surgery twice. We're not sure if it didnt work the first time or if there were two seperate problems, but after the second surgery I havent had any problems. Speak more to your doctor, he should be able to tell you more information and answer all of your questions. For me the surgery meant putting me to sleep and inserting the cathedar through three arteries, one on each side of my shoulders and one in the groin. I have very small scars that arent very noticable and I went home the next day.
- Q:My vehicle has 160,000 miles and has burned 2 quarts of oil at 3000 miles. Someone told me to change the PCV valve because sometimes a bad PCV valve can cause oil consumption. I appreciate your assistance.
- A PVC valve, or anything else for that matter, for a vehicle with 160,000 miles on it that's losing that much oil is probably a bad investment... A rebuilt motor might be a good investment if the rest of the vehicle is sound. If you're not willing to do that, any other shiny new part you put on will end up in the junk yard.
- Q:My Rodeo 96 has a P0440 code (Evaporative Emissions Control System problem). I have visually inspected the hoses on the engine; double-checked the gas cap is tight; but have not looked at the fuel tank sensors and connections. I've noticed that the EVAP canister purge valve solenoid is switching non-stop (click-click-click noise without stopping). Is it the expected behavior?
