cdnboxster,
I had a class 3 oil leak on the passenger side.
When I changed the oil I saw oil that looked to be coming out of the far front spark plug tube area and also some coming from around the middle spark plug tube.
I purchased six spark plug tubes w/seals from RockAuto for less than $20.00 shipped to my house.
I also purchased a boat plug from Wal-Mart for $3.69. The boat plug worked perfectly. My only issue was pushing the new tubes w/seals back in. I gently used a crowbar and they popped right in place.
I replaced two spark plug tubes w/seals, but my oil leak persisted.
My mechanic identified the problem as a loose oil sending unit.
My car (99 Boxster) has over 213,000 miles.
