A few broken rockers did not stop KGB-Racing BMW 2002 from attending SCCA Solo Nationals in Lincoln, NE.
Three weeks prior to the departure date at American Autocross Series
event at Marina CA a disaster struck. In the end of the day car lost
power and start making a lot of noise from the engine bay. Fear we had
was that the bearing were gone, but to a pleasant surprise, after
taking the valve cover off we discovered that the problem was in the
head. Exhaust rocker for #1 piston was broken. The pad fell off and
was sitting in two pieces next to the valve spring. Lucky for us it
did not fall into any oil passages.
A quick call to 2002Haus and the car was on it's way there to get the problem resolved. On Monday i get contacted by Rob who is there to give me some bad news. It was not just one, but 3 broken rockers. Decision was made to get the head to the machine shop for inspection and recommendation. The solution: rebuild the head with new valves, rockers, springs, and guides. Since we are already taking it all apart it was a good idea to do it all.
Lucky for me, Rob and the machine shop put everything aside and had the car ready by Friday in time for 2 days of racing with BMW CCA and SCCA. Practice is always good a couple weeks prior to SCCA Nationals.
