Squeaks at an idle, loud! It's not a belt or accessary. I adjusted the belts, checked alignment on the alt and ps pump. Finally I pulled the belts off and started it and still squeaks. Sounds like the front of the motor. Something not oiling/ Timing chain?

Header/exhaust manifold leak.

timing chain hitting the china covers can hit around the front seal can hit around the top of cover . timming chain can hit some block if a double row roller chain . the PCV valve can make any were from a buzzing sound to a dry bearing noise . the base plate of the carb could be loose and many other thing as well. bolts to long in the fly wheel /flex plate hitting the back of block . the damper rubbing on front tin or timming tab . mechanical fuel pump going south ? front pump bearing in trans or converter thurst washer . bendix drive on starter no coming all the way out of the fly wheel
