289 engine rear main seal leak
 

Has anyone tried any of the engine additives to swell gaskets to stop leaks. I realize replacement is preferred. I would like to make it through the summer and do the work this fall so I can enjoy driving it for the rest of this summer.

i dont know if your 64 has a pcv valve or not if it does it has to be hooked up and working or the seal will leak.

Most of the cheaper ones on the market like Lucas and Barr's won't do much this is the best of the bunch if it won't fix it it's tear down time. https://gobdp.com/blog/rear-main-seal-stop-leak/ Lots of youtube videos on this product.

I've tried them all, there is no magic fix in a bottle!
The only way to stop an oil leak is to install new seal.
Drive your car as much as you can and enjoy it.
