Hello sir Jims2x,

Actually, yun din yung ginagawa ko or mas grabe pa kasi po nilagyan ko yung yung exhasut pipe ko right after sa exhaust manifold ng B.I. pipe provision for washing the exhaust pipe with water. Binababad ko po yun ng powder soap or liquid soap or minsan diswashing soap tsaka turn-on the engine and rev hard! Problem ko po hindi itim na usok, bluish-white na usok na mabahong amoy po during start-ups, idle and accleration while engine still not in normal operating temperature.

Tyvm.
