SR20DET Rocker Arms and Valve problems....
Just to keep this short and sweet, I miss shifted to a lower gear and red line the piss out of my SR. continued to drive fine. the next time I drove it I made it about 2 miles normal calm driving and tossed all the Rocker Arms from the exhaust side only, and breaking the cylinder 4 rocker arm.
Now I replaced that rocker arm and went to start the motor and I broke the same position (cylinder 4) rocker arm again. The engine did not get a chance to start as well. After cylinder 4 rocker arm broke for the 2nd time the valve to the rear on the exhaust side was jacked up, the retainers were not seated properly, and the valve spring assembly was sitting higher than the adjacent valves. I reseated the valve clips springs ect. now that 1 valve is sitting higher than all the rest in my head. My questions; Has this happen to any one else? What ended up being the problem? I feel like I broke part of the valve off and it is now going up further. I just don't know. Would be soo nice to have a small inspection camera.
