oiling

Do you always need the by pass at the oil filter adapter, pro,s, con,s ? Thank you.

Don't know if I'm posing in the correct section but I have a olds 455 in a jet boat the valve covers fill with oil I believe it has a high volume oil pump any suggestions would be appreciated again I'm new to this forum I pulled the motor check the bearings they look good is a stock motor aside...

Dose anyone run a pre-oiler on a twin rajay system. A seperate 12 volt pump to oil feed the turbos before startup and after shut down. Or is just leting the motor idle a few minutes enough. Thanks for any help. I'm new to turbos.

We lit my new alky motor off today. Before hand I primed the motor with a drill on the oil pump till we got good oil press (70psi). Started it the oil press gauge went to 80, ran it mabey a minute checked timing shut it down pulled the valve covers to check things out, one side full of oil...
