The sleeves were then secured in place and allowed to set-up overnight. It's important to keep in mind that the Loctite is there just to seal, and not hold the sleeves in place; that's eventually done by the heads being bolted on. Sleeved blocks (wet or dry) must never be washed in a jet wash without honing plates attached or the sleeves will be lifted out of position due to block expansion and will not reseat themselves. This is true even for aftermarket aluminum blocks. The preferred cleaning method is hand washing prior to assembly with warm soap and water.
