I am getting ready to put on the oil injection block off kit on my trail blazer.Do I have to take off the motor or can I get to it by taking my carb. off?

 

Its actually pretty easy. Removing the carb does make it a little easier. So does removing the pipe. You definitly do not need to take the engine off.
Don't forget you need a single trottle cable with the kit if you don't have one alreay.
