Q:Pressure/Vacuum Relief Valve??
The pressure relief valve is to protect a tank or piping from rupturing from excess pressure. A vacuum relief valve would prevent tanks and piping from collapsing from too little internal pressure.
Q:valve mismatch?
Wherever you are get out. You are about to be ripped off. This will probably be too late. I gather the code you gave is the trouble code, as they are called, from the cars obd. The code 300 is random / multiple cylinder misfire. The code 302 is cylinder # 2 misfire The code 420 is catalytic system below threshold bank # 1 Deciphered this means you have a spark plug misfiring in cylinder #2, bank # 1. The misfire is causing a rich gas mixture in the exhaust system that is detected by the sensor and therefore it says you have a catalytic converter problem. I would suggest you replace your spark plugs, if they have a lot of miles on them. Are they the original plugs ? I f so they are probably due. Get out of there and go find an honest shop that will not rip you off. Now that you know the problem they can;t cheat. I don't know what all that other valve business was about but all you have is a misfiring spark plug.

Q:Looking for a BBb 6 valve tuba?
I don't know how long you've been playing tuba but 6 valve BBb tubas are virtually non-existent. No current brass instrument manufacturer will have that in their line-up. Tubas with 6 valves are already rare and are pretty much limited to F tubas. If you want a 6 valve BBb (I don't know why you even need/want that many valves) then your best option would be to buy a 5 valve BBb tuba and having it modified to include a 6th valve. Either way, expect to pay a minimum of $10000 (ten thousand) for the instrument.
Q:check engine light- valve cover gasket?
the oil may need to be changed check your water and transmission fluid check the brake fluid, have someone to put a new gasket in that is where you may be loosing oil
Q:How does a thermal bypass valve work?
Many block valves in steam systems have much smaller bypass valves designed to make it easier to control the heating of cold steam lines during startup. Some control valves have by pass valves to permit work on the control valve without interrupting service. The heat exchangers have by pass valves so they can be taken out of service if they are not needed or for repair and maintenance.
Q:2007 Nissan Quest Fuel shut off valve?
2007 does not have a shut off valve. Sounds as if some one has used a non programed key Nissan Imobilizer has detected the aftermarket non programed or key with chip embedded in the key has failed. After 4 attempts the car turns on lock mode and it is tow truck time. Gather up all the keys you have they all have to be reprogramed. And it is a good time to have two complete sets of keys and remotes money allowing of course. Only computerized lock smiths and Nissan dealerships can introduce keys. Is there a red light that looks like a car with a key lighting up when you attempt to start the car?

Q:intake valve replacement?
if you have did a compression check and know for a fact that the valve is bad the head has to be removed and then checked for leakage and cracks before you install it back on,those was bad to produce small cracks between the valve guides,if it checks ok then have the valve replaced,the cost should be about 600-700 on doing this one,that was a good engine those cars had in them,good luck.
