Hi.ive just done an oil and filter change put in some lovely fresh oil shiny new filter run her up checked for leaks .none found  all is good.then pouring the old oil back into an empty can wait what's this in the drain pan....my sump washer...shit.

NO it won't....it's there for a very good reason ...don't worry......take out the sump plug and stick your thumb over the hole in the sump or block it temporarily, (you may lose some oil but that is better than potentially frying your engine)  .... put the sump plug washer onto the sump plug  and replace and top up..I would always  recommend a new washer BTW

Thanks just had visions of losing lots of oil doing the plug out Nd back in with the washer.a well placed thumb and only a couple of tablespoons lost.
Thanks

Hopefully you did it when the engine was cold?

I have a magnetic sump plug with washer and (touch wood) never find anything attached to it.

I always recommend a new washer at each change, old ones can be re-annealed but for the sake of a couple of quid use a new one
