[QUOTE="webb06, post: 1355423, member: 7680"] We recently had a truck in with a similar situation. Recent rebuild by the custom himself. Had Oreilly do all the machine work and he put it together. After rebuild it showed no oil pressure on the gauge but started and drove fine. When we got it we immediately check oil pressure with a manual gauge and at idle it was like 4psi and at 2000 rpm it was at 14psi. After pulling the engine out we found the freeze plugs for the lifter galley on the rear of the engine had been left out causing a HUGE low pressure oil leak but it was inside the rear cover that's siliconed and bolted on. Installed freeze plugs and checked all bearings in the lower end, removed heads and pressure checked valves to make sure valve guides and stem seals were okay and put it all back together. Problem solved. Oreilly ended up paying for that bill. Sent from my iPhone using Tapatalk [/QUOTE]
