I hate to say this, but "another one".

I see nothing in that procedure about locking the engine at TDC before starting, I also do not see the use of cam locks before starting, and I see the use of set screws in an attempt to hold the shaft from moving. All of this is ill advised for an entire litany of reasons.

The only known method of doing one of these that cannot end up with jumped timing or other problems is the published LN method: http://lnengineering.com/files/IMSR-Instruction-Warranty.pdf

Over the years, we have had several cars flat bedded into the shop after blowing an IMS update because they used a method other than the one LN Engineering developed. Some of them we were able to save, others not so much.

If you followed this procedure, I think you are in trouble and the cam timing is off.
