Camshaft endplay was an issue on that engine. Also skirt collapse and
sticky gudgeon pins (wrist pins)
I had the engine on my 1990 Aerostar replaced under warranty to get
rid of the noise. My 1989 went over 250,000km with the noise - never

A friend had the noise and running MMO in the oil (Marvel Mystery Oil)
cleared it up Figure it was a sticky pin. Did not help mine.
