[quote=jdmccright]Check for a leak in the oil sump pickup tube assembly...bad seal or not seated fully. quote]


the oil pump screen needs to be installed into the pump body securely. the pipe end you apply sealant. then tap the pump screen into the pump body..the screen must be parallel to the pan bottom....

if the pickup is not installed correctly you could have these problems of low/no pressure at lower rpm.....

Otherwise, listen to other posters. Something's causing undue pressure drop at the low RPMs. You can change to heavier weight to help some too. 10W40, eg.

I know you love this seafoam product ....you say here to pour a can of seafoam into the crankcase....you know that this is well above the recommended amount....I would follow the instructions IF this engine does indeed need a cleaning....maximum is 1.5oz seafoam/quart of engine oil....
