cas problem????

[koullis]

Hi, yesterday i was cruising along the beach and when i found an empty space i floored it. i hit the rev limiter and since then my car runs only with the two middle cylinders. i say that because when i removed no1 and no4 coil it made no difference, when i removed 3 and then 4 the car was trying to die. i checked the spark plugs. 1 and 4 where wet. i changes all 4 of the, changed coils and ignitor. still the same problem. only 2 and 3 coils are firing.
might be the cas? injectors are ok probably because afr is around 10.

car sounds lika a subaru now. i have a link ecu and the rev limiter is set to Hord setting.

Take off the cam cover and check the rockers. Hitting a hard rev limit can cause the rockers to jump off the pivot and then break.

exactly what happenned. left and right rocker arms of the first Cylinder where found broken in the head. even thoug i had greddy rocker arm stoppers.

Is the head scrap now or is it repairable?

 

[koullis]

don't know yet, have to take it apart and see. from the first look it seems ok. it needs 2 rocker arms and 2 retainers.
hopefully that is the only damage to it.

Hopefully you can find all the pieces

i did find all the pieces but i do not know if a piece hit something and made more damage.

Good start, I would be checking the cam lobes etc for any scoring etc
