hello

usually its a bad seal at the oil level sender in the engine tank. sometimes we can cure it by cleaning the tank sometime by using a wire tie on the od of the sender. if you remove the sender/screen assy it must be correctly oriented on reinstallation or it will not work right. the other part is the seal at the filter nipple. if you remove the filter you MUST insure the seal is removed as well. always use a new seal on reassembly.

good luck and keep posting
