noise is defintaley a rubber noise, sounds like a loose belt and is 100% coming from the balancer or just behind it, balancer is not hitting or rubbing on anything, could it be the front seal? noise is gone when engine is cold , but after about 2 min if warmup it starts and gets louder as engine warms up, absolutely a rubber /belt type noise.. is it possible to run the engine with the balancer removed????to see if the noise goes away? could it be possible that if the engine has too much blowby and that it is causing this issue?i have a pcv on one valve cover but if I remove the oil fill cap on the other cover you do notice a little bit of preasure.. maybe I could install a pcv or breather on the other cover, any ideas. will pull it apart this weekend , but just don't wanna pull it apart and find nothing
