Big Block Valvetrain Issue
Question is on my BBC 402. First one is #6 intake rocker arm adjusting nut set's about 2 threads in on stud when adjusted while the other's are the normal 6 to 8 down. Head's are newly rebuilt by a reputable business.
And second is #3 exhaust and #5 intake rocker arm is dry, pushrod's are turning and valves lift the same as other's. Fortunately the arm's, ball's and pushrods are not burnt or blued. When I pulled the pushrods they did have oil in the bottom half.
These are original arm's and was thinking that is it possible that the pushrod seat at the arm is worn to the point that the passage is blocked traveling through it cycle. A good replacement upgrade set of arm's are fairly inexpensive and thinking I might start there. ??? Any other idea's before I start pulling lifter's. Thanks all!!!!
