    I have taken a video and posted it on youtube
    https://www.youtube.com/watch?v=F76VjBzXvAc

    Also found a post on a Rover V8 forum with a similar noise on an engine rebuild and they are saying it can be the cam shaft and you need to run the engine at 2000rpm for a long period to let it all bed in. Im wondering if my new push rods have moved things and loads around.
    Im also still worried the rod guide plates are rubbing on the new rods.

    Squeak?? Just a thought and perhaps a long shot, but if you have had the plugs out, have you got them all seated properly?
    In another direction, is there still a squeak with the clutch disengaged?

    One more thing I forgot, I did have 20W 50 oil in it before the change and now have Mobil Super2000 10W 40 as lots of forums were recommending it for older American engines..

    Sorry, hadn't seen the video when I posted the reply above. Cancel that, it's not plugs or clutch! So hard from a video but it sounds ancillary (alternator or water pump bearing). It was still there with no belt on? If that's the case then it can't be either of those. Easy to check the new pushrods/guide clearance with the covers off (sounds a bit excessive for that). Might also be worth checking for air leaks in vacuum pipes (again seems excessive for that too). Good luck - I hope it isn't a cam
    BTW I always use 20/50 in these old V8's (and always have done). In my view that's what they were designed for but 10/40 won't make an alright engine squeak!

    Appears louder on the drivers side. Difficult to tell. Sounds more like water pump. Try the screwdriver to ear on the rocker cover hope you will narrowed it done.

    I have ordered a stethoscope from Amazon ! Getting really worried having watched another video with a similar sound and it was a cam follower.
