The Oldsmobile LX5, 3.5L V6 is a (DOHC) dual over head cam, engine. It doesn't have rocker arms, but roller cam followers. The followers itself can fail in the form of a faulty roller, but more likely the hydraulic tappet/slack adjuster that the end of the follower rides on or the valve spring itself is faulty/broken.
Personally a drop.
in a Roller Coaster the first drop must be the tallest or in other words the fastest more speed that the roller coaster gains at the start make it allot more fun.
Yes absolutely, Roller Coasters ( depending on the type ) are very able to descend down a vertical angle. Vertical Drop , Dive , Eurofighters roller coaster and more can drop down a vertical drop, some roller coasters can even descend down steeper than vertical drops!!
Sheikra is not a scary roller coaster because when you do the drop you feel nothing at all.

the highest drop is 25feet but it feels like eternity
55 MPH
The feeling you get is like the "butterfly feeling". This is because of the negative gs affecting you as you begin the drop.
it is in the tank drop the tank and then you will have access to it
A wall cloud marks an area of low pressure within a mesocyclone. The pressure drop causes a temperature drop, which in turn causes water vapr to condense.
At the bottom of a drop, when Potential Energy equals zero.
