Info; 2014 Lexus CT200H. 116,000 miles. I bought at 110,000 and immediately cleaned the egr cooler and valve, intake manifold, pcv valve, and added on oil catch can, changed plugs. Now I am getting a strong crank case fume smell when sitting, it will smell up the whole garage and even sitting outside you will smell it walking by. I rechecked spark plug tightness, and all lines from pcv to occ are tight. I did not replace the metal gaskets on the egr cooler or egr valve... Any ideas? I have also stumbled across a recommendation not to over fill the oil, it was full on the stick when cold, maybe pushing excess oil into the pcv valve, but the oil catch can would he full of oil and it doesn’t get much oil but a lot of gassy condensation milky water needs to be dumped weekly... My only other idea is to replace the pcv valve and the gaskets...Runs great otherwise. No codes.
