I have a 3406b motor. It has blow by. This happened when I hired a mechenic to do a top end. I belive that he did not ajust the valves correctly or something happen to the motor. I want to gap the valves to see if this helps out. How would I go on doing this.
NO, valves does not contribute to blow by in this way.Blow-by is the compression of the cylinder getting past the piston rings during compression. Adjusting the valves is a procedure of the induction and exhaust systems. All engines experience a little blow-by which is supposed to pass through the PCV valve ventilating the crankcase. GOOD-LUCK!! BRILLIANT!!!!
try using this link here to help you out. Dont know if you have engine brake or not. but u should be able to still adjust the valves correctly if you follow along with the process.
