Bart,

Absolutely. The oil leak can wait as long as you keep it topped off.

The only problem is that you will get absolutely no warning that your CV boot is about to tear. Once your boot tears, further driving is not recommended. The boot is just a rubber cup to keep the grease in & the dirt out. If you keep driving tho, you can trash a CV rather quickly (depending on the environment you're in).

If you have confidence in your boots, wait till you're ready.
