[700rpm]

Another suggestion: before trying to reinstall the pan, find or buy four bolts identical to the pan bolts or longer, cut the heads off, cut a screwdriver size groove in one end of each, and screw them into the pan bolt holes in the four corners of the block to act as guide bolts when you raise the pan. I always use a piece of 2x4 or 2x6 on a small hydraulic jack to raise the pan from the underside. (The 2x4/2x6 prevents denting the pan with the jack).

I find it easier to affix the gaskets with a sealant to the pan, rather than the block, before installion, but I’ve seen it done both ways.

Also pop the dipper tray out so you can get all the sludge out of the bottom, if there is any. Take care not to bend the end of the pan or distort the tray while doing this.
