First post. 2010 factory V8 4x4 with 220K miles. I have to commute twice each week about 250 miles each way. Each trip if I sustain 2K rpm for a couple hours on the freeway, drive a couple miles to my house and switch off, it coughs a big plume of smoke on start-up. Some mechanics are thinking PCV valve. I thought I read some time back that the PCV Valve was in the DS valve cover and there was a recall I likely missed, so I bought one. Before I commit a couple hours, can anyone confirm I am correct If not, thoughts? Thank you in advance, Jim
