So I have just installed a teksid 2V with a fresh set of heads.
I have a knock and I cant find where. It is a used shortblock but looked to have very few miles on it and rotated fine before I started the build.
Anyways, I have a knock just above Idle. As I ease into the throttle a little, it shows up. its there before it steps down to idle, then it goes away. when I press the throttle more than just partial, it goes away. It is always there kinda like on the edge of engine load where it is super low. Whenever I ease into the gas it shows up, as I press more, it goes away.
-I have listened with a stethoscope and cannot locate anything. It does not appear to be comming from pan area. Or, the valve covers.
-I disconnected the spark then fuel to each cylinder. I've been told it is the way to check for wrist pin knock. None had an effect on the noise.
-Hooked up a timing light and it seems to be in sync. with the valvetrain (1 knock per 2 rotations). I have tried retarding timig in case it was detonation, no response.
could it be a guide or tensioner problem? I can't get any sound out of the front cover really either.
It sucks to build an engine then have stuff like this. Anyone have an idea?
