Q:I need a valve cover gasket replacement because mine is leaking a tremendous amount of oil. The mechanic says it will cost about $269.00 plus tax. I wanted to make sure this figure was the average since I do not know a lot about cars. My car is a Mitsubishi Diamante 2001.: The gasket set is probably $ 20, so double that to $ 40..... 270 - 40 is 230, divided by 2 man-hours, which is the usually dealership minimum, gives $ 115 an hour. I DON'T THINK SO !!!! Unless you live in Hawaii where everything is expensive, that sounds steep.... real steep. Dealers around here get like $ 85 an hour, so two hours is 170, plus 40 is 210 bucks; Still killer money for the dealer..... I'd question that estimate ask if there is some extraordinary challenge to working on your car. It is possible there are accessories mounted over the valve cover that will have to be moved, or that's it's a canted V-6 with one valve cover tucked up against the fire wall. Be nice, smile, ask questions.... Maybe even have someone show you what has to be moved on your engine to get at the valve cover(s). If you're going to pay that much $$$, you should learn something, also.

Q:What do D71, D371 and D341 represent in butterfly valves?: D71 is a handle to clip butterfly valveD371 is a turbine to clip butterfly valveD341 is a manually operated double flanged butterfly valve

Q:How to use the fire butterfly valve properly?: Clamp and groove type and signal butterfly valve, the first two have what requirements of installation, the operating handle can rotate to open and close the valve installation, signal wiring, mouth down, to prevent water and caused a short circuit three line grounding and alarm line for leakage protection and monitoring of the valve open or closed, general are in line with the alarm valve or flow indicator matched with water, indicating the spacing of not less than 300mm, no other special requirements

Q:Hey YA! I am looking at getting an 01 Honda Prelude this month and valve adjustment keeps coming up when people discuss this car and other cars as well. What is this? Does it cost a lot to do, and is it important? Thank you!: Some cars have little hydraulic gizmos to keep the valves more or less where they're supposed to be. Doing without them is, according to some, a tad more precise, but you have to have the valves checked now and then. (On my old Celica, it was a 60k maintenance item.) It will probably run a hair better afterwards.

Q:For whatever reason, Mazda has made it next to impossible to change the PCV valve on the 929. I'm going to have to pull off the plenum and the passenger's side valve cover to replace a $2.00 PCV valve. Before I get too involved, I need to know the torque specs for the valve cover. Also, any other tips on this process would be greatly appreciated. Can I reuse the old valve cover gasket if it's still in good shape? Should I use any kind of sealant in addition to the gasket when I put it all back together? Thanks in advance, by looking at this motor, I can tell I'll have my work cut out for me (for a friggin $2.00 PCV valve, it's usually SO simple!). Like I said, any and all help is greatly appreciated.: you do not torque valve covers down, buy a new gasket , I would get a good quality rubber one and some blue rtv sealer, clean any crap off the valve cover no glue no bits of gasket nothing, same thing on the head surface, glue the gasket on the valve cover, let it set, then carefully put it on, start with the bolts in the middle and work out finger tight all of them, then just snug the bolts down, dont crush the gasket, you can also use a light duty locktite to hold them in place, and often times old valve covers are warped, it is too your advantage to make sure its as flat as you can get it, or spend a few bucks a buy a new one. your choice, but snug the nuts down good with out crushing and bending the thin sheet metal of the valve cover.

Q:Which is better, the round two lobe butterfly valve?: Can be directly installed in the ventilation pipe, connected with the wind pipe, used to control the speed, adjust the indoor air, the double structure diagram can reduce the space length of the blade is unfolded, and also has the characteristics of small airflow resistance, convenient adjustment etc.

Q:My quot;check engine soonquot; light came on yesterday and soon after that I took it to the nearest Midas to have the diagnostic test run on it - they stated I needed an ERG valve. I have no clue what it is and was told that it could run $160. - $300. for my 1900 Astro van. what is an ERG valve? I have noticed that my van has a low humming sound when I'm driving it.: EGR stands for exhaust gas recirculation. It recirculates your exhaust gases back into the combustion chamber to lower temperatures and NOx emissions. This valve commonly gets clogged with carbon due to the fact it's recirculating exhaust gases. If the diaphram is not broken or damaged and still works, frequently you can simply remove the EGR valve and have the carbon cleaned out. It's a dirty job, but can be done if you can get to the EGR valve. If you do need to purchase the part it typically runs about $175. Labor charges will depend on where it's located.

Q:Butterfly valve network and ordinary butterfly what is the difference?: Butterfly valve used in the network structure, closed with the more closed, the more tight function, reliable sealing performance, after opening and closing, make sure that the cover is completely out of touch, to ensure that the sealing surface is not damaged. The sealing surface is made of stainless steel, corrosion resistant, high temperature resistant, long service life. With two-way sealing function, medium flow is not affected by the installation restrictions (if only one-way control medium should be used to seal the installation direction) is not affected by the spatial units, can be installed in any direction.
