Is this the timing mark? | | | | | Joined: Nov 2006 Posts: 2,544 Shop Shark | | Shop Shark Joined: Nov 2006 Posts: 2,544 | Get some acetone on a rag and do more cleaning on the flywheel. You should be able to find the bb once you get it cleaned up more.

By watching the movement of the rocker arms, you can determine which cylinders' valves are ready to adjust. I use a method called "companion cylinder" valve adjustment, where I watch the rocker arm motion on one cylinder, and adjust the valve clearance on another one that's at the top of the stroke at the same time. I'll see if I can find one of the threads where I've detailed the procedure, and post a link to it. Jerry Edit: Check out this thread: https://www.stovebolt.com/ubbthreads/ubbthreads.php?ubb=showflat&Number=661274I just noticed that thread covered adjusting hydraulic lifters. If you've got a solid-lifter engine, do the "rocking" thing the same way, but use a feeler gauge to set valve lash instead of the "zero clearance plus 3/4 turn" procedure. If you're doing a rough adjustment on a cold engine, set the valve clearance about .002" wider than specification, run it to normal operating temperature, and re-check the clearance after it's warmed up.

I had to take the flywheel cover off and there it was in between two hash marks and right after a triangle. Adjusted the valves sounds sooo much better also found in the process the pickup tube to oil the roker arm assembly was broken and no oil getting to the valve train, little silver soldering and presto good as new thanks guys

You might try changing the sender.
