FAQ

In place of actual valve oil, can I use WD40? How about baby oil? Are there any household products which work?

One of the best oil that will really give you a smooth action PLUS, not having to put all the time PLUS, really oiling those sticky valve problem. I recommend Sewing machine oil. It may look like water because it is not slimy, nor thick BUT once you apply it, it goes to work immediately. I recommended that for one of the trumpet play er who had issues with sticky valves. He tried it and been using it ever since. the good thing... its odorless not like Wd-40

So outside we have a gas grill. There is a valve to turn when you want to use it. U can only hear the gas going when u turn the burner knobs but say u left the valve open and no knobs turned at all for 5 hours is gas escaping or does it only escape when the grills knobs are turned? Thanks

To answer your question directly, as long as the valve is open gas will continue to flow until its turned to the off position.

My brother bought a trumpet last month, and I've been trying it out but the first and second valves keep sticking. We've tried valve oil, but it isn't working. Any tips?

Remove the valves entirely and wipe them down with a damp cloth and clean out the valve housings of the trumpet. Then apply a generous amount of oil to the valve itself before putting it back into the instrument. If the problem persists check the valve casings for dents. If cleaning it doesn't work or there are dents, take it to a local music store and see what they can do. It shouldn't cost more than $20 unless there is a serious problem with the instrument.

I have a 1997 Toyota Corolla. My check engine light has been on. I tried to get my car smogged and it failed. I then got an oil/air filter change and just yesterday I replaced the EGR valve which was the result given after 2 diagnostic tests. The mechanic gave me my car and the check engine light was off, I've only driven about 5miles and the light is back on. I have to pass smog asap to register my vehicle. I plan on calling the mechanic back and telling him the light is on, but could it just be a sensor?

All synthetic oil wont burn. But if the piston rings are shot and you'r failing on hydrocarbons, that's an expensive fix. Some states have an emissions waiver, maybe limited to older vehicles like yours, where if you show DMV you'v met their waiver threshold of spending on fixing the specific emissions prob that caused the failure and it still fails, they'l give you a pass till next inspection, or maybe only 1 yr. In some states it's not transferable when you sell and can only be used once per vehicle.

Need some info. Ok, four valves per cylinder is better than two valves per cylinder. Fine, why did Ford REVERT to only 3 valves (my guess is to save cost SOHC)? Audi and VW are using five valves per cylinder on some cars, does this offer any advantage over a four valve engine? Maserati even experimented with a six valve per cylinder!!!! (see link) http://www.maserati-alfieri .uk/alfier... but abandoned it (my guess is cost again?) Why are we stuck at four valves or would more valves actually render more horsepower? Pop some ideas best answer to reasonable answer...

Think of an engine as an air pump - obviously, we want the least amount of restriction for the incoming air and also the least amount for exhausting the compressed air. The ideal situation would be to remove the head during the intake stroke and put it back on during the compression stroke, but, obviously, this isn't possible. On a naturally aspirated engine, the intake is the most critical because the air is moved only by a relatively small difference in pressures. The exhaust stroke, on the other hand, is aided greatly by the super heated temperature and rapid expansion of the gasses. Two intake and one exhaust valve seems to be the most practical and efficient solution - adding more vales means smaller valves and an increase in the overall complexity. I seriously doubt that Maserati ever abandoned ANY automotive idea due to cost restraints. It's far more likely that adding more valves than three or four simply resulted in diminishing returns. Sometimes the allure of a new buzz phrase is nothing more than a marketing ploy - a 16 valve, DOHC, four cylinder engine, for example, is a pretty impressive resume for an engine, regardless of whether it actually is the optimum performance set up or not.

okay, so i have a 2003 cr125 that i wanted to trade for a 4 stroke bike, and i found someone with a 2006 kx250f that wants to trade. He said all the bike needs to be running are 4 valves. The bike is in very good condition from the pictures i saw. How much are the 4 valves going to cost if i bring it to a mechanic shop? is the trade worth it? or should i just keep looking? thanks!p.s.- my cr is in absolute mint condition, and i never even rode it because it is just to much bike for me and i am not use to 2 strokes

I'd leave it if I were you! It will need more than 'just 4 valves'. You'll buy it and then have to spend a fortune on the engine - not worth it. The valves are not that difficult to replace but it sounds like it's been thrashed. You should take your time and keep looking.

what the valves adjustment spies in the 1979 Mercury-marine engine, 6 cylinder in-line 165hp 4.089L?

If it is an outboard 2 stroke there are no vlaves to adjust, it uses reeds in the intake. If it is any type of 4 stroke get a repair manual for proper specs.

looking to get a greddy type rs blwout valve for my sti, but i wana noe wut exactly da blowut valve does....kause i just got da car and i bought warranty, and i wana make sure ma warranyt doesnt void.....and how hard would it be to change da blowout valves....frum ma old 1 to dis new 1......so just incase ma warranty does void kause of da blwout valve wenneva i have problems i could switch it back to da original 1HELPPP???

I WORK FOR SUBARU AND I HAVENT HEARD OF ANY BLOWOFF VALVE VOIDING THE WARRANTY BUT WITH THAT CAR YOU DONT NEED ONE. THE ONE THERE RECIRCULATES THE BOOST FOR OPTIMAL PERFORMANCE SO IN OTHER WORDS DONT TOUCH IT. OR IS 293 HP NOT ENOUGH?
