Thanks guys. I hope I never need to do it but if I have to one day and if it is possible to do it from the top, I am not getting under the car. I don't care how much of the engine I will take it out. I have torn that area apart many times so it should be a problem.
Mirawho, I don't have any physical limitations but I just do not feel comfortable working under the car for long hours no matter how it is secured.
