always dirty is on a distinguished road
Default Bad valve spring

I recently purchased an 04 2500 w/ a hemi. When cranking it makes a lot of racket in the valve train. It currently doesnt start. The PO told me he was cruising on the freeway, lost all power, and had a sudden, horrible vibration at the wheel. Initially, I thought he snapped a timing chain (that wasnt it). I pulled the valve covers, expecting to see an obvious problem, but everything looks ok. Ive got a couple of intake valve springs that look a little taller than the others, but none that I can wiggle around while closed. Any ideas? I'd also like to do a compression test, but the spark plug holes are so far down in the head. Is there an extention fitting available somewhere? I asked the same ? on dodgetalk and so far havent had that much luck. Thanks in advance.

I've never needed anything but a typical compression tester hose to do a test. Personally, I'd want to start by finding out why the valvetrain is noisy.

when I broke a valve spring and dropped a valve my truck wouldn't start like normal either but if I moved the gas pedal or even held it wide open while cranking it would fire but the noise got worse and if there is damage it could get worse as well by doing this.

I think I would just go with a compression test and see what you get but it is likely that you have a broken spring.

The valve springs were fine, the intake valve seats dropped at 1,2, 7, and 8.

Yeow. That engine has been severely overheated.
