Mercruiser 260 v-8.
All cylinders are up to about 170 compression except for one which is showing 105. If I put a few squirts of oil in it it gets up to 120-125 so it must be going past the rings. We haven't ran the engine yet in the water and I was wondering before we go through the process of putting everything back together should we bother with the engine. This one is a little close to call.
