I have made a cock up and over tightened the rocker cover, which had bent inwards. I didnt notice but when it wouldnt start (again) i took the rocker cover off. You can imagine my face when I saw that rockers 2 and 3 were dislodged out of the push rods and the rods were jammed up the sides of the rockers. :oops2: :

I removed the shaft and checked the rods which wernt bent. Refitted them all back together and with the rocker cover off it started.

Anyone else had this happen?

Could it have damaged the valves or do they not usually foul the pistons. Anything else to worry about?

Cheers

by the sounds of it you have been lucky as the rods could not push the rockers so the valves have stayed in the closed position because of the springs. i doubt if the rocker cover would make the rockers do this so look for another cause, did they come undone? has the camshaft been damaged? are the cam followers okay?

I have seen the strengthening ribs inside these rocker covers break the spot welds that hold them in from over tightening but all this does is makes a clacking noise. If it has started ok then your valves should be alright.
