Q:I HAVE A 2003 FORD EXPEDTION THAT IS IDLE ROUGH,AND WILL EVENTUALLY STALL. TODAY I FOLLOWED THE PCV VALVE HOSE TO THE BACK OF THE THROTTLE BODY AND NOTICED THERE IS A BIG HOLE ON THE ELBOW OF THE HOSE. HOW CAN I CHANGE IT? CAN I JUST FORCE THE HOSE OUT AND SIMPLY PUT A NEW ONE? BEEN HAVING THIS ROUGH IDLE /STALL PROBLEM FOR A WHILE I CLEANED IAC VALVE, THROTTLE BODY CHANGED THE AIR FILTER AND ALSO CLEANED THE MASS AIR FLOW SENSOR, I HAVE A P0171 system to lean(bank 1) code

So, the rubber elbow hose has a hole in it. Your best bet is to get the replacement from the Ford dealer. Yes, you can buy just the elbow part from the parts counter at the dealer. If they start acting all dumb (and won't help you or sell you the part) then, go to a different dealer for the part. Another thing you could try is a used one from the junk yard BUT, it's been my experience that the rubber gets too hard and the PCV valve needs a lot of encouragement to be removed. Sometimes you'll damage the used elbow by trying to get it off of the engine or removing the old PCV valve to put in your replacement valve. That's why I recommend getting a new one straight from the source. They are pretty simple to change with ordinary hand tools and some mechanical know-how. You just pull the elbow off of the port that it's attached to on the engine. The valve will probably have a steel clip that goes around the hose at one end of the valve inside of the hose. You simply squeeze the clip with a pair of pliers and tug at the valve until it comes out of the elbow.

Q:I have a 1993 Oldsmobile Cutlass Supreme and I think I have the case of the blow-by. The engine had high mileage, but was rebuilt b/c it stalled while driving. 3.1L V6 gasoline engine. The fuel filter and the fuel pump are brand new. Now we have the same problem a few months later. It stalls while driving. Its been sitting a while and won't start by itself, so I pulled off the air intake hose off of the air filter to spray starting fluid into it. I noticed oil puddled in the air intake hose, so I looked for the PCV valve on the rocker cover. There is a tube going from the air-intake hose to the rocker cover. I popped out the tube from the rocker cover and there is no PCV valve. Just tube. Is that where the PCV valve is supposed to go? If not, where can I find it on the engine? And could that possibly fix the blow-by and the stalling engine? I'd appreciate any help. Thanks in advance.

Q:What is the effect of nylon coating on butterfly valve plate? Thank you

Mainly media will not be contaminated by rust on the body, you should say that the central soft sealing butterfly valve, the central valve is generally cast steel or cast iron material, so useNylon coatingLining up. There are soft seals, sealing performance is relatively high
