I have a 1985 S10 Blazer 4WD with a carbed 2.8L , the engine has a loud "knocking" noise ( sounds like a brick in a dryer). Does the carbed engine have a anti-knock sensor? It sounds like a connecting rod or main bearing is bad. The noise only gets louder not faster at higher rpms

Thanks in advance for any help

Does it shake ? Is it automatic ? can youuse a rubber hose to your ear to try to pin point where the sound is strongest at . If it does not increase with engine speed , I dont think it would be a connecting rod . Maybe an exhaust leak near the firewall that makes it sound louder. Don't know about the sensor. Rob

Torque convertor.

it does not shake ,it is an auto, and the noise is coming from right side of engine ,torque converter is a better answer than replacing or even rebuilding the eng. thanx you two
