Q: How long will a new spark plug last in a car with a leaking valve cover gasket?

asked by on May 04, 2017

I have a leaking valve cover gasket. I have to wait until next week to fix. If I put a new spark plug in it how long will it take to start misfiring again? I just wanna get through the week and spark plugs are affordable.

My car has 150000 miles.
My car has an automatic transmission.
