Re: Full-Flow Oil-Filter Kit from "Motor City Flatheads"
[QUOTE=Tarheel;434052]Some spin-on filters will have an internal check valve to keep oil inside the oil filter when the engine is off. This helps the engine get oil faster when it is just started up. Some do not have the valve. Check the specs on the filter you are using- this may be the cause..[/QUOTE
This is true... I ran into the same scenario with the MCF pump and switched to Moroso filters. Running just fine now for eight years.
No need to burp it now.
