Hi All, Our B16a2 has been using loads of oil recently (a litre for 500 miles!) There are no obvious leaks from the engine, and no blue or black smoke from the exhaust. The only symptom we noticed is that there was a ton of white smoke when we vtec'ed it hard yesterday. Someone suggested that one of the valve seals might be gone? The engine has done only 30,000 miles, but was unused for a year and a half before we put it in our 93 Civic hatch. Does anyone know what this might be, or any tests we can do? The engine has 0w 40 fully synth oil- is this the wrong grade?? Please help!!!
