In order to take care of a smoking problem, I've decided to remove the IP and send it to a Bosch shop for calibration/tune up. New timing chain, IP timing adjustment, and pop testing the injectors hasn't done anything.

I've stumbled across a few tips and tricks about how to go about it.

My understanding is that I should advance the crank to 24BTDC on the compression stroke (#1's cam lobes up) in order to faciliate reinstallation.

I'll then have to remove the fuel lines (metal and plastic), the plunger rod, and disconnect the vacuum line.

After that, it's 4 13mm bolts - two on the top, one on the bottom, and one at the rear? I have the 90 degree wrench for this as well as the drip tube to set the timing when it comes back from the shop.

Is there anything else I need to know to remove it? Any tips to get myself in a better position to go about the reinstallation?
