Noise / rattling during cruise /idle with video

[chrger1967]

Not likely.....with low idle oil pressure, it's likely that a rod bearing (and possibly a main bearing) is failing, limiting oil availability for the corresponding rod bearing. Use FSM clearances for bearing clearances. A collapse lifter has a sharp metallic clicking sound when operating. Pull both right and left valve covers and observe rocker arm operation. OK, do the easy, unrelated stuff first...from exhaust leaks to torque settings of the RR tire valve cap, to the oil pump drive etc......you are going have to remove the oil pan (or pull the engine) and check bearing clearances, one throw at a time, b4 the failing bearing damages the crank......this will not be an easy fix or an inexpensive fix.......just my opinion.......

I'm getting some ticking so I pulled the valve covers off and found the rocker arms had movement side too side. It sounds like what he posted in the video. Wouldn't a bearing give you more of a knock then a tick?

Hi, first post here and first older Mopar

I have a noise, a ticking/knocking noise when i drive, specially during cruise at around 30-50mph.
What could this be?
I have enough oil in it, 20w50. Sounds harder in the video than in real life, but it resembles that of a lifter problem.
Quiet when cold start but comes as the oil heats up. Very annoying, was also considering manifold gasket on the headers...
Engine is a 440 in a 69 coronet sedan but engine is newer.
Oil pressure hot idle is 10-15psi, hot cruise at around 1800rpm we have around 40psi.

Here is video Video here


Best regards from Sweden.

Forget about your ticking, how did you load that video?

It happened to me!!!!

Did you find out what the problem was?
