Pulling the engine is the last resort for me. I'm hoping it is something that can be done with the engine in the car but if it comes down to me having to pull the heads for some stupid reason then the motor is coming out. I don't want to pull it but there are a few things I need to do to the car that would be much easier with the motor out so I am just thinking ahead.
I will get the leak fixed though. If that does mean pulling the motor I'll do it. Too me there is nothing more embarrassing then firing up your car and pulling away from a puddle left for everyone to see. Plus it's making a mess on the bottom of the car.
