I bet Hotrod has run into this problem wit 235's and large oil filter. The engine runs great, some oil leakage on new front oil seal. After about 100 miles of driving it will loose a quart and will not drop any until next oil and filter change. Any ideas what could be going on. Oil pressure is low with 6 quarts then comes bake up to 30 with five. Doc
