you can see if its leaking if you have the spark plug in tight and then fill up the spark plug tube with gas and see if it leaks out if it doesn't its still leaking from the top one
you must remove the entire rocker arm assembly... inside each rocker is a little button lifter. that's the ones to be replaced... To set the entire rocker assembly back in place, you will need 4-5 hands to squeeze the springs and position the rockers over the valves
By removing the valve cover from the engine, then removing the rocker nut on the bad rocker. Refer to a technical manual for torque specifications, as this must be properly torqued!!!
No. The valve uses an hydraulic lifter that is built in the rocker arm assembly. The whole rocker arm has to be replaced.
Over reving the engine, ( to many RPM )The rocker arm nuts need replaced ( The locks are worn out on the nuts )The rocker arms are worn where they set on the valve stems.Need to check everything closely.
I think the only time you have to do any cutting is when you're using guide plates.
inside rocker cover
Rocker cover gaskets need to be replaced.
Check inside and around the door or on the rocker panel
Rocker contains a carpet to catch light sediment. You rock the cradle and then take the rug out and there's gold underneath, if your lucky.
That area on the car is called the rocker panel. I suppose you would refer to the trim as the Rocker Trim. A body shop or supply house would know what you meant.
Yes and they should all be changed at the same time.BUTIf you are changing rocker arms it indicates the inside of the rest of the engine is badly worn. DIETL: I have replaced a single rocker and would again if it made sense. In the case where I replaced one, the rocker had experienced a bearing failure likely due to a defective bearing from new. All the other bearings were fine and the rockers operating well. That car is still running over 50K later with the one changed rocker.I've personally only seen three failure modes for rocker arms. First is worn bearings in the rocker (if fitted - some model cars have no rocker bearings). Second is a worn bearing surface where the rocker contacts the valve stem. Third is a broken rocker.It would be a very rare occurrence for all rockers to break. It would also be relatively rare to have all rocker bearings fail. This would imply a lubricant failure. In this case, I'd say that a lot more than your rockers are damaged. In the event that the valve contact surfaces are worn, I'd suspect that your cams are worn as well. The latter two are both conditions that imply significant general engine wear.
Yes you can, as long as you did not bother the other ones. Just adjust the one you replaced.
