"Evening all,\n\nHave a small oil leak from the sump plug on my 156. Have tried to tighten it but the thread is stripped. Garage down the road suggested helicoil for £90. This seems expensive but I know very little about them. Swapping the sump for a good s/h one is something I'd rather not get involved with (oil, oil and more oil.) \n\nAny suggestions? Has anyone perhaps had a helicoil done before or even done one themselves? I know the 156 threads are prone to this.  \n\nCheers, Tom"
