Re: 156 sump plug stripped
Same thing happened to me. I only noticed when the oil pressure warning light came on !
My local garage told me the bolt that was in there was absolutely huge, so it was obviously a problem that became progressively worse over time (under previous ownership, I hasten to add). He told me that the helicoil/insert solution was now out of the question.
I had to have the whole sump tank off, and sent to an engineering workshop for the hole to be welded and then re-machined.
My mechanic was not amused because apparently the tanks are a bugger to get off..........and on, as they don't use a gasket but some special paste.
