The picture shows a partial seizure on the Triumph gudgeon pin. I pulled the engine down this winter. The seizure was between the pin and the small end rod bearing.
I am one lucky dude. A full seizure with everything breaking apart would cost big $. Barrels cost $1,465, cases cost $4,265, a crank is $891, etc.
South Bay Triumph in Lomitas, Calif. has a lot of experience with land speed. They sold me a set of pistons and they strongly recommended that the pistons and pins be coated, and they did this. It is a teflon coating, as I recall. If you call them, ask for Matt or Carlos. They know the details.
The new triumphs have oil radiators and two oil pumps. One pump sqiurts oil directly under the pistons to cool them, like a Suzuki. I was running a good quality oil, so lack of lube was not a problem. The pistons have some minor scuffing with the classic pattern one gets when running a cold engine hard. The pistons heat up and expand faster than the cylinder expands.
Drag racers run cold engines very hard. Maybe one of them on this website will know about this problem.
