I am replacing all the timing mechanisms and cam phasers in a current engine build. There’s a build up of that seems to be a light grease. Should I do an engine oil flush with a product that cleans this with only a 10 to 15 minute run, or will Sea Foam Motor Treatment work better? Would it be OK to use Sea Foam now before I change the oil, then again and let it work for 3,000 miles? Please reply ASAP, as I will finish the reassemble tomorrow.
Those are great questions Jerry. I think you have a good plan. You can add Sea Foam right away and try to let the engine run for at least 20 minutes before changing the oil. You can then add Sea Foam right away to the new oil and allow it to work for the 3,000 mile duration of the oil life. You can use as much as 1.5 ounces per quart of oil in the crankcase. Either way, Sea Foam should work well (and fast) to reliquefy the light grease that you mentioned.
