Hi all,
I'm running a 1300 Fiat X19. It's a lowish milage car, 57K, and shows excellent oil pressure on idle (about 25-30psi) and at 3K rpm (60 psi)
The problem is that when I start it from cold I get a knock for about a second until the oil light goes out. If I then immediatley stopped the engine and started it again - no knock. Also no knock when the engine is restarted when warm.
I understand that it's the same angine as the 128 and other more modern models.
It's as if all the oil is draining out of engine so there is nothing to pump from cold.
I heard that the oil filters need to be the correct type with a non-return valve ? I believe I have a correct aftermarket one installed.
Anybody have any ideas ? could the filter to this ? could incorrect or cheap oil do this ?
thanks
Lee
