SOURCE: the rocker arm ticks

before trying too much the lifters will sometimes bleed off some of the prime they have. first try putting in a pint of marvel mystery oil. if that doesn't fix it run an oil pressure test to see if you need a new pump or new lifters

SOURCE: Rocker arm failure

Did the timing belt break at one time? Aside from the obvious of it sounding like your son did what mine did and tried to race the vehicle beyond it's abilities if the timing belt broken at one time it may have damaged the valves. If the valve impacts the cyclinder it is possible that it can damage the rocker and cam. When you pull the head off this time have the head re-worked and valves replaced. This should solve the problem.

What would cause rocker arms to not move when engine starts


Hi Robert:
That's a scary question. If an engine can run without the rocker arms moving it must have some kind of magic.
If the engine turns over but does not start, I'd be looking for a broken timing chain.

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

I removed rocker arm assembly and did not line up timing marks did i waste the car 2005 dodge neon sxt


If you removed the rocker arms then the exhaust valves will all be closed and so will miss the pistons. How ever if the inlet valves were not working and the rocker arms were still in place then there may be damage to inlet valves.

What causes a tapping noise when the engine is running in a 2002 Saturn L200?


Lifters, push rods and rockers arms. That's what does it. To check lifters. Start the engine and get it up to operating temperature. Put a half quart of transmission fluid in it and let it run. If the tapping goes away, let it run for about 30 minutes. Drain the oil and change the oil filter. Refill it and add some oil treatment first, lucus, slick 50.. what ever you prefer. If the noise doesn't go away. Look at the rocker arms and push rods, they should be polished, replace them as needed, I would still put the additive in.

Broken lifter arm 96 honda prelude?


Interesting question. If you think a lifter arm, which I presume is also called a rocker arm, is broken, remove the valve cover and find it. All the rocker arms are visible, and should be easy to see.

Installed new oil pump and now have broken rocker arms


THe rocker arms are broken because there was not enough downward movement in the valves to allow the cam to complete its turn. IT happens when the valve spring retainer either hits the top of the valve guide or the valve springs are fully compressed forming a solid block . If you have hydraulic valve adjusters I would be suspicious of a lack of movement (seized) in the ones that broke the rocker arms

Valve clearance for mitsubishi L200


Take the rocker cover and the upper timing belt cover off.
Set No 1 Cylinder to TDC - use the markings on the cam spocket to get this - and confirm it's on the compression stroke by check both inlet and exhaust valves are closed and on the heel of the cam.
In this position, check rockers 1,2,4 and 5.
Take care with the feeler guage to make sure you're right under the pad under the adjuster screw properly and completely passing under it, not sticking part way.
Rotate the engine (crank shaft) 360 degrees. This should bring No 4 to TDC - confirm that both inlet and exhaust valves are closed and on the heel of the cam.
In this position, check rockers 3,6,7 and 8.

Clearance for Intake and Exhaust is 0.25mm at normal engine operating temp.

Don't forget to fit a new rocker cover gasket and half moon seal (use something like Hylomar to help make sure the half moon is sealed properly - usual suspect when rocker cover leaks at the back of the engine).

2004 Cavalier broken rocker arms after head gasket repair.


Rocker arm issues are common in that car. They can happen without any reason. This is not going to be cheap to look at. When the head was repaired it had to be removed. The timing chain might not have been properly tensioned. That would cause the timing chain to slip and then you have pistons slapping valves and spark plugs. This cause rocker arms and pushrods to bend or break and also can damage pistons.

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.
