67 Dart 270...Project Old School

I have been chasing oil leaks on my Dart, but I finally got all of the oil leaks plugged. One piece of equipment that was invaluable in finding leaks on the back of the engine is a telescoping mirror. With this new tool in hand I was able to determine I had oil leaking from the back of the intake. The leak was right in the intersection where the head meets the deck and the back of the intake meets the deck.

I pulled the intake and scraped off all the old gaskets. I cleaned all the mounting surfaces with carb cleaner before mounting the new gaskets and applying a liberal amount of black RTV in the corners where the end gaskets meet the head. I let the RTV skim over for 45 minutes before installing the intake and torqueing it down.

I also took the added step of removing the passenger side breather and installing the correct grommet for a PCV valve. I installed a new PCV valve and connected it with hose to the large port on the back of my Holley 3310 carb. I also took the opportunity to swap on the quick change secondary spring housing and purple spring.

I took the car on a test drive Sunday morning to Panera Bread Company for breakfast with my two sons. When I got home I checked all the usual places for any oil leaks and found none. YIPPEEEE!!!! ...wait, what is that dripping off the drag link? That's not oil...its...its...coolant and water? I followed the stream back to a seeping freeze plug. The good news is the freeze plug is accessible through the maze of header tubes.

Now I know what I am doing next weekend.
