2G Rockers fell off

[Ethan Trenka]

I took off my valve cover to replace the gasket and sparkplugs. When it was off i noticed that both rockers in one spot fell off and were in the engine just floating. i looked and nothing seemed damaged. The rockers are in good shape and the lifters seems good. I dont know what made them fly off.

Over-revving, collapsed lifters or bent valves cause the rockers to get spit out.

Check for any damage to the cylinder head. I would even preform a leak down test to make sure the valves are sealing correctly. If everything is good you should be able to put it back together. I saw a video online where he showed how to put the rockers back in without removing the cams.

A few things could be the reason why,

A lifter thats not pumping up enough,
Cams thats have been reground,
Lifters that are not shimmed enough,
Just general wear and clearances get a bit bigger,
High revs and do this also seems alot more on the intake side since its pushing the rocker forward (this rocker has less chance to stay on) due to its angle and direction of the cams rotation
