1968 396 BBC tick
Hey guys, been awhile since I posted but still check in to read.
Long story short...
Car has less then 200 miles on it since engine rebuild (miles on it by me, never saw the road till I finished it enough to get on the road), however I did not rebuild engine, was done before I bought the car, finished the car up last year to the point where I could drive the car and enjoy it a bit. It's about 98% done at this point, just AC and heater hoses left. So engine was rebuilt over 10 years ago and finally saw road last year again.
Anyways... Buddy talked us into going and following them down to Good Guys with him and another friend. (he has 69 Mach 1 other buddy has 62 Chevy II) so we did, we got half way there and Camaro lost oil pressure, I pulled over, engine sounded fine, I thought maybe sending unit issue, but then started to hear valve train noise ticking, so I shut car off and called Hagatry to send roll back, they asked anything special, is aid car had drop springs and was low in front, they said ok, tow driver arrived and said car was to low to pull on roll back with winch and asked if I could pull it on, I said I really don't wanna start it back up, he said I am gonna tear your front vallance up if you don't get the car a little up at an angle to winch it. We were not in a great spot, so I did, the engine chatter was louder this time and I pulled it on roll back and shut off less than a minute, but I was pissed at having to start it.
I got it home, drained oil, Oil was clean, no metal or glitter.
Removed oil filter, cut top off and checked flutes, they were all clean.
I assumed at this point, pickup vibrated off or shaft spun collar on dizzy.
Pulled pan, oil pump itself had vibrated loose, so either builder forgot to torque or it needed lock nut. I had already bought new pump with pickup welded on and also new heavy duty shaft with metal and pinned sleeve. So put those in and filled with oil and new filter, primed pump and oil system and started car. Engine chattered a little at first that followed RPM and then seem it quieted down some. However, I still hear a tick that seems to follow engine RPM. It seems to get softer after awhile, I started car this morning and it's much quieter, but I think the tick is still there, but now wonder if it's just normal valve train noise and has always been there and I am obsessing cuz of the issue and the chatter before? The noise can not be heard with the hood closed, but with hood open you can hear it slightly, almost hear it better standing outside garage door so it kinda echos out??
Hydrolic lifters, non roller, Lunata Cam, lil aggressive grind, but not crazy.
Good Oil pressure 42-45 at idle, raises over 60 psi when increased RPM
1) Normal Valve noise
2) Adjust valves cuz lifters collapsed when they lost oil?
3)Stuck or Collapsed Lifter?
4) Rod Bearing?
5) Something else?
