Review on OTC 6488 Ford SOHC Service by Jermaine Chowdhury

Well made tool kit. The case is labeled with part numbers so when reading the instructions you can easily identify which tool goes where and what specific tool you are looking for. What I have found is that when rebuilding a Ford V6 4.0 SOHC the number 1 piston is aligned to top dead center before the heads are installed. You can leave it there during the installation process. When installing the cams on the heads, set them to the position they should be when the #1 piston is at TDC. I found that this eliminated the need to use tools to align timing chains, cams, etc. It was turned on when checking. I only used the tools needed to hold the cams in place by tightening the bolts holding the gears to the cams. By inserting some flywheel bolts into the back of the crankshaft and then placing a large screwdriver over and between the bolts, the crank could be locked in place, preventing the cams from turning. This made it possible to tighten a few bolts without having to use a whole set of tools each time.
