Anyone up for a game of name the knock?:gee:
This is video of 2 cold starts, the wretched noise is clearly audible.
I'm hoping one of you guys have heard this one
It ain't loose torque converter bolts, I made sure of that.
knocks at start up and shutdown,
appears again when revving down
no start up knock when engine is fully warmed
does not change with RPM
has no repeating pattern
knock sound seems to come from center of camshaft galley.
flexplate is intact, bolts are threadlocked, no cracks on inspection
there is no vibration
oil pressure is constant 20 at idle 40 at cruise, 55 at cold start
motor mounts are all new, jacked engine up and started it, got the same knock
Trans bolts are all tight
Engine oil is full
there is no misfire, or loss of power
cat mount and catalytic converter are new. No noise from these components.Exhaust does not hit crossmember
Possible knocks:
cam walk (RIP)
crank walk (RIP)
cracked flexplate (would get better with warmup?)
dragging starter (would'nt knock at shutdown)
