I have a significant oil leak at the front and rear of the left side of the engine oil pan while the engine is running only. After carefully investigating this for a number of days on a lift, I can't seem to pinpoint the leak. It appears to be originating above the oil pan and I see it coming from between the front motor plate and the block. Is there an oil gallery plug under that plate that could be leaking? I see the engine has a plug in the front and rear and it looks like exactly where this oil could be originating from. YIKES!!! Is this a known issue with these engines? I would hate to think of what needs to go into solving this leak if its that end gallery plug. Any thoughts would be helpful. Thanks.... Tony
