It may be that a thrust washer between engine and transmission had disintegrated (or was missing) which in turn allowed over half an inch of 'end float' of the crank shaft to damage a plate which joins the flywheel to the torque converter. (This plate seems rather flimsy considering the forces involved). That may account for the noise.

Big ends! - It does it when warm when the oil is thinner.

Does it seem more pronounced at a certain RPM? (about 2300 was the "sweet spot" on a supra from memory)

thanks is this expensive to repair.

£200:00 to £250:00 for the above, but it may be best let Mr T quote you first, I may be wrong
