Macktech689 Posted May 25, 2014 Share Posted May 25, 2014 Not familiar with the term casing vent, can you be more specific or add a picture ot the component. Quote Link to comment Share on other sites More sharing options...
wheeler73 Posted May 25, 2014 Share Posted May 25, 2014 Do you mean the ccv? If there is smoke coming out of it the dealer needs to check for blow by. Quote Link to comment Share on other sites More sharing options...
Macktech689 Posted May 25, 2014 Share Posted May 25, 2014 I was thinking he was looking at the CCV outlet tube but didn't want to assume. Smoke there is not good, indicates a cylinder problem. I have repaired 2 low mileage MP-7 engines this year with cylinder failures due to faulty piston cooling pressure sensors. No smoke at the tube but steam from coolant in the oil from cracked liners' Quote Link to comment Share on other sites More sharing options...
wheeler73 Posted May 26, 2014 Share Posted May 26, 2014 Hey Macktech689 seen that once on a mp8 with a eroded #6 liner full of pin holes. Quote Link to comment Share on other sites More sharing options...
Macktech689 Posted May 26, 2014 Share Posted May 26, 2014 Cyl. liner cavitation usually takes years to develop and poor coolant, Peteguys engine has around 8500 miles on it. Quote Link to comment Share on other sites More sharing options...
