SOURCE: Turn key to start - nothing happens

I had same problem w/ my '88 Ram50. Turned out to be bad contacts on the battery cables. Temp fix and test was to put a little screw between the post and the end connector. Didn't have a problem then, so I replaced the cables.

SOURCE: 2005 Dodge Stratus ? Camshaft Position Sensor causing problems (I

I had the same problem with my '05 Stratus SXT 2.4 DOHC. I've replaced the cam pos sensor and it seems to be running fine right now. On the Dodge forums a lot of the guys say that you need to replace the crank pos sensor too. I've bought one of those just in case it comes back again. Hope this helps.

2: no engines stated, of the 4 opted day one sales.
3: no year car, wow , now that makes this 10000 harder.

Whats the cause of a slightly bent pushrod and a rocker arm to nearly come off?

the high lift cam has no compensation and so the valve retainer bottomed out causing the rocker to slip sideways and bend the push rod
you would have been better fitting a prolonged duration cam rather that a high lift for the following reasons
1 --- you can used standard rocker gear
2 ---there is no valve bounce at high rpm
3 --- smoother air flow in the inlet manifold so there is not such a stop/ start action when rpm is low
4--- less wear on cam followers and cam lobes
cam shafts are all about open duration so longer open with smaller lift is better than the same duration with a fast up and down action

Torque settings for rocker shaft for a 1998 7k toyota 1800

There is no such thing as a rocker shaft. There is a cam shaft, rocker arm assembly, Rocker arm, lifter etc. If you are talking about the rocker arm assembly that bolts to the head, it is 58 Ft/lbs. If you are talking about the actual rocker arms, you tighten them till they contact the push rod and the valve stem and then you put oil control clips on so the oil does not spray and you start the engine. You tighten them down till the chattering noise goes away, then back them off 1/8 to 1/4 turn.

I have a 2003 Dodge Ram 1500 4.7 with 166k still ticking after lifters replaced.

If there was a problem that caused the rocked to become dislodged I would have checked the rocker bushes and shaft and replace both. The rocker where it works on the end of the valve wears a recess that will move and then click back into place. I would use a 20w-50 grade oil and additives work at reducing friction . IF you need it to thicken the oil then there is something worn out.

2005 dodge dakota has a rattle for 5 seconds at

Sounds like a rocker arm is out of adjustment or one of the rocker arms are worn more than the rest. If you find one loose rocker arm and the rest are tight then the entire rocker assembly will need to be removed and the one rocker arm will have to be replaced. Thats on a V6 and V8 models . Now on the four cylinder you have to remove the timing belt cover,unbolt the timing belt and hold tension on it to keep the belt from jumping off the crankshaft gear. Remove the rocker arm cover and you will have to remove the cam to get to the roller rocker arms. There is alot of work to do to get this job done. If you do not have all the tools to do this with, then it would be better to take the truck to a mechanics shop for repairs. Hope this will help you.

Rocker arm come out on jeep chrysler 3.7 eng

A rocker arm is the arm that sits on top of the valve stem and connects to the push rods 'the push rods sit on the cam so when engine is running, the push rods go up and down in a timed sequence and with the rocker arms, open and close the inlet and exhaust valves. the rocker arm is located inside the valve(rocker)cover .If the rocker arm gets loose or comes out.
Check the nuts on the shaft which holds the rocker arms.either the shaft or nuts are got loose.They need to be tightened.Don't make it too tight or too loose.  Too tight,and they don't flutter right. Too loose,and they allow the rocker arms to wiggle out of whack. Other possibility can be  something is broken, bent, collapsed, or out of adjustment. 
Thanks. you can rate this solution and show your appreciation.

Loud rattle noise in Camshaft

First, your engine has rocker arms, if you have a 4 cylinder you have 8 rocker arms, and if it is a 6 cylinder you have 12 rocker arms. Now if it is indeed a rocker arm making the noise, the cause is most likely a bad lifter or a worn cam shaft.
