  1. 500
Recently bought a 500 that has a leaking head gasket and an issue with the 4th gear in the transmission. I did the radiator leak down test and from all indication the head gasket is leaking. When I drained the oil it had that look to it that anti-freeze had gotten into the crankcase. That's one of my issues.

The other issue is it doesn't want to stay in 4th gear. The other gears are fine. When trying to shift back into 4th the gears grind. Not sure what it is but hopefully will find out when I disassembly the engine.

I currently have the engine on my workbench waiting for an extended period of warmer weather.

Does anyone want to take a guess what might be causing the 4th gear issue? Will report back once I start taking the engine apart and let you know what I find.

The picture was taken by the previous owner before I bought it.

Which brings up a couple more questions. As you can see someone during the 500's life decided it was a good idea to hack the front bumper. Are there any suggestions for a replacement? Should I look for an original or go aftermarket?

Thanks for any help or suggestions that you may provide.
