ok I used the search function and since noises are subjective im not sure if my noise is addressed.
M42 gets this metallic buzzing sound right around 3000 rpms. usually anywhere from 2900-3500 is when its most noticeable and it seems like maybe its getting worse
some facts:
-chain tensioner replaced
-timing chain/sprockets looked almost new when i did the valve cover gasket
-no plastic pieces in oil
-noise happens under load, stationary, in gear and out of gear
-its not the heat shield
-maybe unrelated deceleration whine
-theres a consistent small oil leak somewhere on the passenger side that has everything covered in oil, it drips oil but not enough to need oil often
potential causes ive thought of:
-motor mounts
-water pump
-timing chain/case related (in which case ill be pissed)
-exhaust manifold leak
potentially unrelated but today for the first time i saw the temp gauge start to rise above the half way point after idling for a few minutes at the atm but maybe im being paranoid. i feel like the noise is getting worse but im no m42 expert and i just dont want this thing to take a shit, but by the time i do the remaining "for good measure maintenance" with everything in the timing case ill be enough into it to justify an engine swap
