Hey every one im having a big problem with my 420a engine. I had a valve cover gasket oil leak so i i replaced that. My dumb friend broke the pcv hose and instead of buying a new hose he just plugged it with a cap so then we drive like 10 miles we park and notice drops of oil trail behind the car we open the hood notice that it busted through the fresh valve cover gasket. So now we replaced the gasket again no more leaks from it and now have a legit pcv hose connected and we have also replaced the oil pan gasket and oil filter all things that bursted once the pcv was blocked now we still have a big oil mess and we cannot find where the oil is coming from its not the cam seals we think it may be the oil pump gasket and or crankshaft seal. Any help would be greatly appreciated. :confused::confused::confused:
 
I'd start by wiping everything down as clean as you can get, and then start looking for the source of the leak. It's going to be a messy clean up, but needed to locate the source.
 
I would get underneath and look for the oil sending unit on the back of the block, those tend to fail. While you're there, look at the area where the head meets the block to see if oil is leaking from it.

Like the other fellow mentioned - clean it really well.
