I think I may have a leak from my sump. I am going to get the car up and tighten the bolts up to see if that fixes the leak. If it does not, can the sump be taken off, cleaned, a new gasket put on with gasket seal, without taking the engine out? I seem to remember some time ago that my mate and I did this without the engine coming out, but looking at it now with the bracket on the subframe, it looks a big job and taking the engine out may be easier.
