Greetings! I’ve had my 64 dart for about a year now. Its a fun little car. Made a number of improvements from when I got it. Today I was doing a spit wash of the engine and engine bay with gunk and purple power. And I think I found my oil leak.
But before I post that thread... what is the name of this part that is located where the engine meets the transmission?
That doesn't seal anything. Its a cover you can remove to inspect flex plate.
As mentioned above your leak is probably a rear main seal on the engine. Goes bbetween oil pan and crankshaft
No, you definitely want it there. It helps keep rocks and other unwanted stuff away from your flywheel. I keep forgetting to look around to find one that's reasonable. The inspection cover won't cause an oil leak. And yours is actually in pretty good shape.
I would go with @72Dart6pack that its probably the rear main seal...or it could be the oil pan gasket.
I had a leak on the backside of my 273 that drove me crazy. Without the inspection cover I could see it wasn't coming from the rear mail seal, but I changed the oil pan gasket 3 times and it still leaked. Then I took my time, made sure the pan rails were straight, and used just the right amount of permatex on the corners of the gaskets and...finally got it!!
red is trans fluid, black is oil. Most every leak in the back (main seal, cam plug, etc) will come dripping off that shield as its where its flung off the flex plate or blown back to. you can take it off and straighten it with a hammer and a piece of wood.
