U can get the proper oil filter socket out of hein gerrick for about a £5.00, if u have damaged the canister and it will no longer fit on the socket i would use a small chisel and tap it round at the base of the filter,making sure u dont come into contact with the engine casings. i found these filters just desintigrate if u try any form of strap wrench on them.Buy the tool for future use anyway.
