After giving the RTV a couple of days to cure, I hooked up the fuel lines and reconnected all of the electrical connectors. I fired up the engine, and unfortunately, the noise is still there. I’m really not sure where we’re going to go from here with this engine, but in the meantime, we’re going to continue building the car. The noise won’t prevent us from driving the car and testing the rest of the systems.
Crane disassembled the lifters and found some debris in two of them that they said could have caused the noise we were hearing. The sent us a brand new set of lifters, but I haven’t had a chance to reassemble the engine until now. My dad stopped by this morning and we reassembled the upper end of the engine. The RTV needs to cure, so we can’t run the engine today, but I’m hopeful that we have resolved the noise.
