Ok so im rebuilding my engine have it all apart in process of cleaning everything. Getting the head skimmed and ordering parts in the next couple days. I want opinions on the best break in procedure for the engine other than staying off boost. My current plan for starting is using some oil thats called first start oil. You basically use it in place of regular oil for your first start then let it idle for 20 minutes then drain and change your oil filter then refill with whatever oil you plan on using and go from there. I was just wondering what everyone uses as "proper" break in procedures other than staying off boost. Also im aware of changing the oil and filter after the first 500 miles.
