Im getting ready to first fire an engine. Im basically buying someone elses project (always an adventure). I did purchase it before the shop finished it about a year ago, so I paid extra to have the shop assemble the long block because this is an expensive engine and I wanted it done professionally. There is a lot of stuff with this engine I probably wouldnt have done, external wet sump oiling system for starters, but its all nice parts.

I didnt get a build sheet when it was delivered, so I am going to call the engine shop and see if they still have the details on the bearing clearances or if they have a preferred oil weight for their builds.

But like the title says, this is a hydraulic roller motor. Do you guys bother with a dedicated break in oil in this case? Do you just use a cheap SAE oil with some zinc (VR1 probably) to maybe help ring seal and then replace it after about 50 miles.
