Hi Guy's! 1937 Ford 85 HP engine with 337 miles after fresh engine rebuild. Yesterday while researching a stumbling issue and the way home from a 30 mile drive the night before, I noticed an oil trail coming out of the #1 plug and running down the cylinder head the following morning. I removed the plug and was sickened by the sight of oil on my plug. I took a cotton swab and went inside the chamber and it came out clean. The valves even looked clean. I replaced the plugs with the hotter D91 Champions. I took it for another 30 mile drive, got it back home and the head looked clean. I pulled the #1 plug and it was clean except for a tinnie-wennie bit of wetness each side of the top electrode. Any ideas?

My guess is that the plug was not tightened properly allowing the gasket to leak combustion products and not fire. Tom

There is also a possibility that all the ring-gaps just happened to line up on that cylinder, at that time, which would create a direct path for oil to migrate.

Ok Guy's thanks. Just wasn't sure if a ring had broken during assembly.
