just put a big dent in my 08 550 radiator and im gettin some leakage from the overflow now but nowhere else and its gonna cost more than i want for a new one in aus... should i replace?? any alternatives?? aftermarket etc??
as discussed recently the 37s from OEM are £62 plus VAT in the UK so thats £73 per inlet. the problem as you know is that they tulip if revved on OEM cam and valve springs.
i have had a few machined down that had gone south. suprisingly they can be saved at 36.8mm and with a taper...
