Guys, first 180 miles report:
- 0 miles, two heat cycles (testing for leaks and had coolant leak), changed oil and filter
- for the first 40 miles I had ignition for start default 302 - 10, and kept rpm under 2500, easy on throttle but streaching a bit...
- for second 40 miles I had few acceleration up to 1/2 throttle, and one acceleration where rpm went to 3000 (was not intentional, AOD) and I heard noise (my ass froze...), tried in neutral at home and I got "rod-knock-like" noise with door open when I keep rpm on 2800...chit...$#%$#&#... I froze... oh noooo
Maybe I am just paranoid due to past experience and there is something loose in engine bay...
BUT for first 80 miles I also got some hickup/buckle with "feather" throttle or very, very light acceleration.
Therefore I changed ignition coil, cables, cleaned spark plugs (all looking perfectly like in books on all 8 cylinders). I also raised ignition to 12.
Checked exhaust manifold bolts, tigthened. Check few accessable lower intake bolts, seems good.
Report continues:
- for next 100 miles engine runs better and better with every mile, but there is still a noise present around 2000rpm if You raise and keep rpm for second standing in neutral
I just truly hope if this would be a rod knock I would have more severe problems in 200 miles than noise.
Oil looks okay on dipstick, coolant level is stable.
Mechanical gauge shows cold idle oil pressure 50 psi in first milisecond of start, hot idle oil pressure 20 psi.
Cooling is okay, dash gauge newer went to middle, allthru engine bay is like furnace after few dozen miles of drive.
I plan to lift upper intake, check all lower intake manifold bolts and maybe redo lifter bolts (OEM lifers).
Is there a possbility that I am experiencing detonation (from heads and block shaving and combustion chamber descrease) and therefore I have to advance ignition a bit more?
