Hi, a few months ago i had a problem with my Yaris 1.0 VVT-i. I had a blown gasket on my exhaust and a melted catalytic converter, cause of this problem was that my Oxygen probe (sonde) (I don't actually know how it is in english but in croatia we call it "lambda sonda" ) didn't comunicate with the ECU so the engine was runing rich, burning a lot of fuel, and the incjectors clogged up and the car didn't quite responded to throttle (it sufocated when you added throttle like it chewed and then built-up RPM so we repaired the gasket on the exhaust, buyed a new catalytic converter, fixed the ECU, cleaned the injectors and the car was runing fine but there was another problem with the car, the strange tik-tok noise in the engine, like the cylinders are hiting the valves and mechanic said to me that the chain in the engine is stretched out that controls the camshaft etc, you know what i mean, (again i don't know how it is said in english) but he said that i can drive the car. Later I checked the oil on the car and oil smelled like exhaust gasses so I decided to drive the car to warm it up and to check does it smoke white, so i drove the car and parked it in my garage, it does smoke a little white warmed up and outside was about 5 degrees celsius. It produces that tik-tok sound when it's warmed on a working temperature but when its cold it does not I assume that it is because it has higher RPM when its started cold. When you add throttle when the car is warmed the tik-tok dissapears. I think that the car has a blown head gasket so it burns cooling fluid, oil smells on exhaust gasses and beacuse it burns coolant it build a higher compression inside the cylinder and makes a tik-tok noise? I also filmed a video today so I can upload it to YouTube and post a link if I am able to post it here
I appreciate any help and excuse my english :cheesy:
