Guys, what might cause my oil pressure to go up on my 2.0 16v?
Usually it sits at 4 bar cruising along, maybe drops to 3.5 when warm, but just recently I've noticed it's showing more like 5 or 6 bar when cold and then drops to 4 or 4.5. Is this a sign of trouble perchance?
Apart from the reading being higher than mine (inconsistent Alfa guages!) they sound ok.
Pressure will be higher when cold as the oil is cold too and therefore thicker, resulting in higher pressure. When it warms up its thinner and therefore slightly less oil pressure. So long as its showing pressure and doesn't change much over time you're ok
