"I have twin 671 TIBs in a 44&
"I have twin 671 TIBs in a 44' sportfish. Motors were majored 150 hrs ago. Stbd engine has been smoking, even after running at cruise for extended periods. Detroit mechanic found bad injector and replaced. Smoking problem persisted. Mechanic returned to do compression checks on all cylinders. Readings on all cylinders were within 6 pounds of 475 psi - mechanic said these were readings of a new engine and thereby dismissed any thoughts of blow-by. We still do not know why this engine still smokes. Could there be slop in the wrist-pin on the piston? Could a blower be causing this? Any help would be appreciated."
