The ticking in the morning could be one slightly loose still, you could give all of them a 1/4 turn more, or next cold morning, pull the cover and look for the loose one only and tighten it down. One lifter may be worn or machined with more clearance.
Isn't this fun?

Tim - the ZIM and New Britain tools might be the same; and, they are more helpful than the Snap-On/Proto tools. | | | | | Joined: Jul 2012 Posts: 306 Shop Shark | | Shop Shark Joined: Jul 2012 Posts: 306 | i am real close now , its just when i do a cold start i hear them ,, i will drive it a little and re adjust them ,, 1 other thing right now when hot driving at 180 to 170 temp my oil pressure is 40+ driving ,, but at light it drops to 25 is that ok?? got me worried but as soon i get on the gas it jumps to 40 again ,, the idle is about 500 to 700 rpm just guessing no way to tell ,,
