Oil pressure

Post by Cschaff63 »

My oil pressure when cold is around 4 lbs, then continues to drop off to nothing as it warms, is this normal. Running 10w 30 oil as per engine builder specs.Engin e also seems to get noisy.

The Model A engine has a high flow oil pump with very low pressure. Higher pressure reading at start up with cold oil and pressure dropping off after the oil warms up is perfectly normal. An oil gauge in a Model A can make some worry when the pressure goes away.

Thank you for responding, I was kind of hoping that was the case
