" Senior Editor Mike Allen answers readers&amp;#039; car questions. Q: I have an 2004 Chevy Avalanche and I&amp;#039;m having problems trying to eject my CDs from the player. I have the Bose 6 disc changer that came factory installed with truck and the CDs use to come out with out any issues but in the past year or so it&amp;#039;s been more and more of a struggle to get them to come out. I read the manual and it states that after a long time of CD play the unit will get hot and it might not eject till it cools down. I&amp;#039;ve tried it every which way but nothing seems to work, before playing a CD, after playing and everything in between. Nothing seems to work. I&amp;#039;d appreciate some help if you could give me some. Thanks. JOE LARANJO A: The radio will have to come out and either be repaired or replaced. Q: You and your team write a great column; I eagerly await each month&amp;#039;s PM to see what new car projects you guys can get me into doing. I am looking for a Web site or other source of reference that will take me to the next level beyond Haynes. I tried all data, but the DIY edition is too basic for me. If your answer is to bite the bullet and get the GM service manual(s), do you have a source? J.D. A: alldatapro.com will let you access the factory service manuals. Not cheap, though. Q: Why do the big automakers not use Ducati&amp;#039;s desmo springless valve train design to significantly reduce internal resistance and thus improve overall economy? It would seem that using this design in most passenger as well as trucking engines could have a very significant impact on domestic fuel consumption and pollution. DAVID HILL A: I&amp;#039;ve got a Ducati, and I do all the maintenace on the thing myself. Believe me, it takes a mechanical whiz to adjust the valve lash for both opening and closing rockers.--the mechanical complexity procludes the use of hydraulic adjusters. It&amp;#039;s one thing to adjust the valves on only two cylinders, doing it for 6 or 8 would be very expensive. And modern roller tappets have nearly as little friction as conventional flat tappets anyway. Q: When my car sits in the garage overnight or longer it takes at least 3 seconds of the starter turning over before engine starts. If there is a check valve in the fuel line it leaks back to the fuel pump (tank) . If there is no check value in line the pump must be unable to hold line pressure to be able to start. After the initial delayed starting time, it starts as it should. What do you think? JACK SCHUBERT A: The check valve might be a little leaky, or it might be a slightly leaky injector bleeding off the pressure. Try holding the key in the ON position for three seconds before trying the starter to allow the pump to build up some pressure. Q: I have an 1988 Nissan Stanza. While I was driving the car responded like it had shifted into neutral, so I coasted to the emergency lane. No matter where I put the gear shift, the transmission would not engage. I turned off the engine and the car would not restart. It turns over, the fly wheel turns but none of the pulleys on the front are turning. Any ideas? JOEL HUNTERA: It&amp;#039;s a broken crankshaft.Q: I am having an intermittent problem with fueling my car. Sometimes I can&amp;#039;t put fuel in the gas tank. If I let it sit overnight, it will fuel up. My mechanic does not have the diagnostic tools to analyze the problem as he has a small shop. Any suggestions? TED SOMEROA: Pull the fuel filler pipe out and fix whatever is blocking the way. Hooking the thing up to a computer wouldn&amp;#039;t help with this, anyway.
