Assess the top end condition of this M42

[BimwadM42]

Did a couple maintenance jobs over the weekend, valve cover gasket and chain tensioner.  While the cover was off, took the opportunity to snap some pix.

I thought it might have been a placebo effect at first, but the new tensioner definitely quiets the engine a bit all-round and makes is less thrashy sounding.  The old one had ~48k on it.

Due to the difficulty of trying to compress even the old tensioner by hand and threading the cap, I opted to install the new one as is, in the compressed state and take my chances with the chain slap on the initial start.  It took a little longer to fully pump up than the last time I replaced it, perhaps because I didn't rev it as high as the factory recommends this time, or because the thicker oil in the sump took longer to build pressure.

To my eye, everything was clean and in pretty decent shape.  The only thing that looks out of sort is the lateral clearances on the chain links.
