You may remember that at the spring HMSA event my M3 was pushing a bit of water during each run. Jim and Terry looked at all the usual suspects but came up with no reason for the problem. So we decided to be safe rather than sorry and pulled the engine and sent it down to Terry Tinney.
What Tinney found was the head gasket was a bit too thin and the pistons were just touching the head causing enough vibration to allow combustion pressure to leak into the cooling system and push out the water. It wasn't so severe that it was big problem, but it certainly could have lead to more expensive problems.
Tinney turned the motor around in record time, and last Friday Jim had it back in the car and running. The car will be going over to VRM this week to get on to their dyno for a quick break-in run.
We will be running the car at the SVRA Portland race at the end of July, then on to Monterey!
Hope to see you at either of these events:
