stopping sump pan drips

[John Mason]

I found a quick and easy solution to this problem was to undo the offending bolts until they were almost out the threads, then wrap PTFE tape around the bolt between the sump itself and the oval washer (it doesn’t matter if the tape gets twisted whilst doing this). Then retighten the bolt. This distorts the tape making a tight sealing washer between sump and oval washer. What oil seeps down the threads is sealed not engine side of the sump but on the outside between sump and washer.
Not an engineers way but a non engineer thinking outside the box.
