I wenthru every passage with brushes,soap and water bath,and blew everything out after it was hot tanked. This was AFTER the achine shop blew everything out to make sure everything was open after they installed cam bearings and this problem didnt show its ugly head til about 4000 miles. Im prettyconfident it was all clean. Everyone tells me ive got ocd when it comes to cleaning and checking clearances. Not saying i didnt overlook something, but its very unlikely since it ranfine and still has same oil pressure as when i built it until i climb a hill and ease into throttle or or try speeding up to pass a car. Very light load the op doesnt drop, but go from steady rpm and speed to 1/3 or more throttle it drops. Heres a NEW one to add to the list! Started it this morning after sitting overnight and had a lifter tick for just a second til op got up. Not even a full second but its never done it before. Maybe coincidence???? Theyre sumnit brand lifters and cam
