If you need to replace the rock arm studs.. it is not fun. Video to come.

Short version ( WHEN it works.. ) is you need two nuts. BUT as you know the rocker stud nuts are tapered and not a great option.

So you need to find a M10x1.0 jam nut https://amzn.to/3zHXPri / or regular one https://amzn.to/3F6JQfX. Best if you can find a hardened one. ( Depending on your tie rod or Ball Joint, I have found many of them use a M10x1.0 Castle nut and that works). Then double nut the stud and pull it out by the bottom nut, installation is the reverse.

If the thread isnt too far gone you can get a M10x1 die and rerun the thread to clean them up. https://amzn.to/3thvN4K

NOTE: One thing I forgot to mention.. On the flywheel of the earlier motors there is ONE of the flywheel bolts marked with a "P". Note which hole it comes from. I believe it is the 1 O'Clock position when the flywheel is located properly. It needs to go back into the same spot. The "P" bolt has a minimally larger shaft and the hole it goes into is fractionally smaller to make for a tight fit.

While not "CRITICAL" that its in the right spot ( your motor will be fine.. ). If you do not mark the front pulley for TDC ( Opel did NOT.. with exception of the 2.4L EFI Pulley ) and are using the rear pointer to time your motor by TDC. The pointer could be off by upwards of 7 degrees in either direction.

Later models either did away with using the pointer and used the front pulley or in the case of the 2.4L the timing was fixed by the crank pulley sensor. I will be showing a few tricks on the timing and distributors when I do the next video.
