Q:700r4 throttle valve......?
700r4 Throttle Valve
Q:Are valve cover gaskets easy to change?
Take your time when changing the gaskets. You will more than likely have to disconnect things. Make sure if you remove something it is put back. If you have to remove the spark plug wires, number them. From front to back, the left side is 1-3-5-7 and the right side front to back 2-4-6-8. I mark my wires with a sharpie but they are red wires. I use to use wooden clothes pins and write the number on the clothes pins. If you get the wires mixed up you'll have to get the firing order to get them back to the right cylinder. Good luck, you will appreciate your vehicle more now that you know the work is done right.
Q:rear proportioning valve?
i got a 97 model van setting out side the shop and i went and looked at it and it doesn't have one on it,what are you calling the rear proportioning valve,it has a block that the lines split off of but not a proportioning valve,let me know if you got some kind of special edition or something,good luck.
Q:Leaking Proportioning Valve?
First up is that the valve is not leaking oil, it is leaking brake fluid. That is bad. The proportioning valve controls the brake pressure to the rear brakes. Most of the braking is done with the front brakes and without the valve you could lock up the rear brakes on medium to hard stops and the rear end could loose traction, that would be a bad thing on a sharp turn. With that said please replace the valve I have never seen a repair kit for them. Have you looked at to GM for the part? They may also have knowledge on a conversion of the master cylinder with the valve built in.
Q:96 chevy cavalier heater control valve?
The only valve i could think you are referring too would be the vacuum control on the back of the dash mounted heater controls. They do not have a valve in the coolant lines. The heat turned on or off by a vacuum operated door inside the heater box that merely closes and blocks the heat from escaping into the car. If you are having heater problems first make sure both lines running to the firewall feel hot/warm when engine is at temperature. Secondly you will have to find the actuators under dash on the heater box and make sure they are moving if not ck for vacuum.......
Q:Trumpet valves keep sticking!?
have you tried washing it out? ive played instruments i was going to suggest valve oil first but if that didnt work theres a good chance it needs cleaned inside and out and then oiled.
Q:pressure release valve?
do you change your oil regularly? you could have gunk restricting the oil galleys in your motor and as the oil pump does its thing with no other outlet cause the oil to flow out your dip stick... when you consider how important oil is to the motor there should not be a release valve.... that is a set up for failure... although i wouldnt put it past ford to do something like that... my opinion of course... i would take it to a shop that can flush your oil system... might be hard to find but theyre out there... good luck
Q:Help With My EGR Valve?
Flag is right. You should of got the code from AutoZone and posted it here. A trouble code can have several meanings and the salesperson just gave you his best interpretation with his limited knowledge. You either had a P0420, P1410, P1411, P1661 or P1662 code. More than likely it's EGR Valve Position sensor or EGR Vacuum Solenoid depending on the code. It also can be the wires or connectors that plug into them or one of the vacuum hoses to them. About a $40-$70 fix if you do it yourself. You can pull the EGR valve off to inspect it but you need to replace the $1 gasket under it when you are done. On old poorly maintained engines they can clog up with carbon deposits or the vacuum diaphragm can rupture. You can apply vacuum to the valve manually and see if it opens while you have it off. If you have good lungs you can do it with a piece of hose. :) If it works then it's not getting vacuum and most likely it's the EGR Vacuum Solenoid that opens and supplies vacuum to it. The EGR Valve Position Sensor tells the Vacuum Solenoid to open via the ECM. See if you can't get the code and post it.
Q:does my 96 accord have an oriface valve?
It uses an expansion valve inside the evaporator assembly, part 11 in the first source. If the evaporator valve is not working the compressor will be damaged - by no oil if the valve stays closed or by slugs of liquid spilling out of the evaporator if it sticks open. Fortunately, orifices and expansion valves are very reliable. I bet a standard A/C service (about $100) will get you cool again. If you do anything to disturb the refrigerant loop (trying to charge it at home, trying to change refrigerant system parts) you will only spend more... probably a lot more.
Q:mitral valve regurgitation and surgery?
Have you asked your Cardiologist this question as well as your Primary? I do not know what the reading indicates...sorry!
