Hey all! I made this quick video of me putting in one of my TA dual grooved cam bearings without taking out the crank, rods, or pistons. The only part that I didn't get on video was actually hammering the bearing in, but my advice is go slow and measure to make sure you are centered in the oiling hole(s). I've found that the oiling holes are not centered front to back on the cam bores, so I used a small steel rule to take measurements. And also, make sure you mark the oiling hole locations on the new bearings so you can get 3 and 7 o'clock with the bearing and driver inside the engine. Lastly, I've been putting the camshaft in dry and rotating it by hand after doing each bearing to make sure that everything it still straight and happy. I hope this helps someone! Video: Here's the tool I was using: https://carshopinc.com/catalog/prod...-installation-and-removal-tool/category/2990/ I'm sure any cam tool would work as long as the driver part is removable and small enough, they all seem similar.
