I have an 04 Spec v with 190k, no precat, and valve cover has been replaced. I noticed it burned a lot of oil to the point I now add about a quart every 300 miles. It burns a ton during cold start with a lot a smoke out the exhaust and a lot more when you step on the gas. I also noticed that oil was puddling in the intake where the respirator tube is for the engine. Any ideas? Should I rebuild or buy a new engine?
