I have a issue with my crank bolt yes, I took it to a local garage to check out and they have told me that the bolt has damaged the threads in the crank, I have spoken with mike ref this and the car is going back to him to be inspected and sorted, This is providing the other garage is telling the truth, Again mike has been helpful and kept in contact through out the period, As far as i see it, when you start changing things on a car and nearly tripling the power out put things will/do go wrong or cause a problem? You cant expect any car that has serious work done to it not to cause other areas that are standard to always last? Again TD are sorting the issue i have and mike has been very fair and honest about the situation,
