Leaking oil cI did an oil change on my Duratec/dry sumped car and, against my better judgement, removed the lower oil hoses in search of the missing oil. When I ran it up to temperature there was a small leak from the LEFT (as you're looking at it) hose union, so I tentatively nipped it up a bit tighter. But it still leaks. I'm very concerned about stripping the thread and wondered whether some PTFE tape could be used in this situation? And any advice about how to do this without spilling all the new oil? Which part is likely to strip threads first, hose or oil cooler?
