Re: BD240 pushrod/rocker adjuster interchange
Here's the donor C263:
Worn out BD240 pushrod/adjuster on #4 exhaust rocker:
Closeup of worn BD240 adjuster. The cup end of my original pushrod has definitely worn into the bad rocker adjuster. No way I would swap a good adjuster onto a bad pushrod, so now I'm looking for a straight valve BD240 pushrod:

I also reset all the valves to lash at 0.019" warm. There's considerable less clatter at idle although mechanical valvetrain always has some noise. I have a video of starting and idling with no rocker cover, but it needs to be edited a bit. Maybe I'll post a Youtube link if I get it uploaded.
