low oil pressure when warm basically.
after a while i.e like 2-3k miles i noticed the oil pressure light occasional flicker after a thrash on the motorway when pulling on to stand still, made me wonder, asked on here, spoke to Karl, really helpful, straight to the point
he said what pump you running, i said burtons high pressure, he said, thats the engine fucked then
whipped the sump and mains off and sure enough he was right
I never fitted an oil pressure gauge, wish i had now, wish i had done alot of things differently, but you live and learn, its all part of the expensive ford "experience"
You can never have to many "make you really paraniod" guages
