SP33DD3M0N Posted June 26, 2013 Report Share Posted June 26, 2013 Anyone having blow by issues? I had a friends fathers caravan in the other day for an oil change and the top of his oil filter was soaked in oil actually soaking the paper element in the filter. He went to dealer they say its normal for the 3.6. I have a 2012 Journey 3.6 and there is no oil on my filter at all. I run a K&N filter but there is no oil other than the oil thats supposed to be on the filter. His caravan only has just under 30k on it. He's a little bothered by it. I have never seen it on an engine with such low mileage. Any input on this? Thanks Keith Quote Link to comment Share on other sites More sharing options...
Rubberdude88 Posted June 26, 2013 Report Share Posted June 26, 2013 Maybe an overfilled crankcase? Not sure. Quote Link to comment Share on other sites More sharing options...
bigtsr Posted June 26, 2013 Report Share Posted June 26, 2013 (edited) A bad PCV valve can give you this condition,first place to start without costing too much. If crankcase ventilation is faulty it's one on the first signs. p.s. I think you meant to say it was the air filter not the oil filter.

SP33DD3M0N Posted June 27, 2013 Author Report Share Posted June 27, 2013 Yes I meant air filter. Thanks. Guess I need to proof read first. lol Not over filled, pcv good. I am a tech as well. we have been doing all the service at our shop. The costomer went back to the dealer the forman says its normal but a few other techs say its not........so...... whos right? I have seen this before but it had a plugged pcv and another had well over 250k miles. engine was well worn then. this one only have 30k on it. My 12 Journey has 63k on it and I dont have an issue at all. But the Foreman of the shop at the Dodge dealership says all 3.6 pentastar engines have that same blow by. This is the only one I have seen out of a fleet of well over 500 3.6 dodges we have come here. Thanks for the input guys! Quote Link to comment Share on other sites More sharing options...
bigtsr Posted June 27, 2013 Report Share Posted June 27, 2013 This doesn't apply to a in the case of Caravan but it's more common to modified or turbo'd engines. You find that many of the above run "catch cans" in PCV line as the greater air pressure causes oil to blow by the rings and despite the pcv valve it passes into the filter box. It's possible the engine is just bad, only a leakdown pressure test will reveal if it's a cylinder problem. Quote Link to comment Share on other sites More sharing options...
