Good Day!
I have a 1994 Corolla XE with a 2E engine, whenever I start up the engine I hear a light knocking noise but when the engine gets warm or maybe the oil has circulated the noise dissapears, I tried to have the tapets adjusted but the problem still occurs, it has overheated a couple times due to stuck thermostat which I replaced and failed radiator fan and clogged radiator but all ok now, It is also losing some oil, and has a blue smoke in the morning when I start up, hope to hear from you soon! THANKS!
