Helicoil size
« on: 23.08. 2022 17:09 »
Hi, anyone know the size of the thread of the rockerbox studs into the head? As one has stripped so need a helicoil the right size. I'll fix the rockerbox leaking if it's the last thing I do. Four attempts now the threads gone......

Same happened on my alloy head, purchased V coil, and worked a treat

Great thanks for replies. I should have said Alloy head. V-Coil set looks good I’ve used them before for spark plug threads
