Did your oil light stay on while limping home ,if yes you may need to drop oil pan & check for sludge plus clean oil pickup screen ,changing DI cassette does not help oli presure light issue ,but will cause more serious electrical wiring problems ,if u continue to drive with it ,when it gets really bad it will start burning the connector & wiring harness ,get oil light problem checked ASAP ,could cost u a engine if u keep driving while light is on,good luck.

looks as if the pan was dropped some time before I bought auto, as can see new gasket sealant around pan, but will drop again to make sure, Oil light was out as limped home, but did come on at times, I pulled over , let car sit and light went out, limped a little more light on ans so on until parked

ok ,sound like it for sure u have a oil pickup screen blockage problem ,this time try & remove as much debris as u can both from top valve cover area & lower engine block ,i have found that a good brand oven cleaner works great ,much better than grease remover ,good luck .

should I continue to use synthetic Oil or regular? would this help or hurt engine, oil has a little gassy smell to it, If i clean out pick up and other related parts will this continue to be a maintance issue?

no u should be good after that because i did that to my engine 3 years ago & i am still running strong with lots of mod's to engine , plus i only use full syn oil ever 3000 miles ,it is best to use only full syn oil ,trust me i know ,don't play cheap with your engine , just saying ,good luck.
