Have enough oil on had to pour a quart into the lifter valley to wash out any coolant that is spilled/leaked into it during removal. Then change all the oil BEFORE you fire it up (will get all the coolant/oil out of the pan). Install cheap filter and oil and let it run a few min, then change oil again using a quality filter and your choice of oil. Lessens the chance of spinning a bearing or 2. Been known to happen after LIM jobs.
