Yes i know all about the head tick issue. no i dont think it is or i wouldnt be posting.
Background
Motor has less than 3500 miles on it. rebuilt last winter due to low compression.
block bored .20 over, JE pistons, comp cams, comp springs & retainers, manley valves, bronze vale guides, new timing chains and tensioners, file fit rings.
motor was done by a local machine shop. it started making a quiet ticking sound about two weeks after i put it back in the car. it only did it when the car was fully warmed up. i took it back to him and he didnt really have any answers for what it could be. since it wasnt very loud i left it go for the rest of the summer and i knew it was there but most people didnt pick up on it. there was no performance loss from it. dyno tuned right where it should.
car sat over winter, got it out like a month and a half ago and the tick is much louder than before. it now ticks as soon as the car is started, i can hear it while driving over the exhaust. the volume of it varies, sometimes i cant hear it at all other times you can hear it over the driving noise and exhaust.
my first thought was maybe he didnt use the bronze valve guides as it resembles the head tick. i really dont know whats going on, i took some videos maybe someone will know.
i used a stethoscope and the noise is most audible where the coil cover has 32 valve. i point to it in the first video. it sounds like clicking not tapping if that makes sense. it also increases with rpm.
first vid is of the noise from the front side and bottom
second is of revving
third is with the stethoscope ear pieces over my phones mic. there is a good few seconds of the sound exactly as i hear it with the stethoscope.
Cliffs:
New motor started ticking quietly when hot
sat over winter now ticks very loud at any temp
sometimes tick goes away and or gets much quieter, but always come back
