mherman2 Posted May 3, 2013 Report Share Posted May 3, 2013 Fellas, On the Shelby Bash a couple cars behind me said they say some blue smoke when at speed and in gear and coming off the throttle. Upon my return from the Bash I brought the car into a Ford Dealer here in SD. ford started an official oil consumption test on the car. It has 10k miles, 2012 Boss 302 LS. I started reading up and found quite a few more earlier 2012's that people had issues with burning oil. In any event, after 800 miles the car burned 3.5 quarts of oil. Ford has been great on the phone with the dealership working through it as the car is under warranty. Yesterday it passed the compression test and leak down test. The head engine mechanic working with Ford is guessing Rings or Valve guides. I love the car I hope the issue can be resolved but Ford has been great thus far working with us. Will keep you posted. Any guesses out there? I will give the answer when I get it. Car was meticulously maintained to the point of the issue arising. Link to comment Share on other sites More sharing options...
mikeljgt500kr Posted May 3, 2013 Report Share Posted May 3, 2013 Very strange, I have heard nothing but positive things about those cars and that engine from the dozen or so I know of. I would guess valve guides, that is where the assembly line process can screw it up, rings are harder. Link to comment Share on other sites More sharing options...
Secondo Posted May 3, 2013 Report Share Posted May 3, 2013 I know of a Boss owner that traded his in recently because it burned too much oil. And my buddy's 2011 5.0 is down 3+ quarts (8 quart capacity) every time the oil is changed. Something is not right with those engines. Edit: I hope you get your car repaired properly. Please let us know the cause if you can. Link to comment Share on other sites More sharing options...
mherman2 Posted May 6, 2013 Author Report Share Posted May 6, 2013 Ford has asked me to put 500 more miles on the car for another oil consumption test. Will keep you posted. Link to comment Share on other sites More sharing options...
Torch40 Posted May 7, 2013 Report Share Posted May 7, 2013 Drive up to San Jose and pick up your tires. That will be a good test. Link to comment Share on other sites More sharing options...
IngotSilverSnake Posted May 7, 2013 Report Share Posted May 7, 2013 My 2012 5.0 burned about 2 quarts of oil in the 2500 miles I put on it before trading it in on my 2012 Shelby. Glad to report that my Shelby does not use any oil at all! Link to comment Share on other sites More sharing options...
springer Posted May 7, 2013 Report Share Posted May 7, 2013 There are several threads in various forums about the Boss 302 burning oil. It seems to be a common complaint and needs to be addressed by Ford. Link to comment Share on other sites More sharing options...
David Hawkins Posted May 7, 2013 Report Share Posted May 7, 2013 Could it be possible that an Intake Gasket could be bad? Maybe a small crack in the Intake where it mates to the Heads? Link to comment Share on other sites More sharing options...
RogerS Posted May 7, 2013 Report Share Posted May 7, 2013 Most likely a ring issue. Roger Link to comment Share on other sites More sharing options...
MMcGuirk Posted May 7, 2013 Report Share Posted May 7, 2013 It is widely known that early B302 motors had this issue. Ford changed the ring design and that solved the oil consumption problem. I personally know 4 people who suffered the extreme of this issue - blown motors. Ford did step up and replace all 4, no questions asked. Link to comment Share on other sites More sharing options...
NordicShelby Posted May 7, 2013 Report Share Posted May 7, 2013 My 2013 Boss 302 DOES NOT burn any oil at all. I have 5,000 miles on it and change the oil about every 1,000 miles. I would say about 3,000 miles is on the road course and it never has used oil at all. I know that 2012 Boss's had issues with oil consumption and blown motors but have not heard of this issue on 2013 Boss's. Glad I waited so Ford could get the bugs worked out and I also didn't have to pay the 2012 Boss Admins. Link to comment Share on other sites More sharing options...
mherman2 Posted May 7, 2013 Author Report Share Posted May 7, 2013 Drive up to San Jose and pick up your tires. That will be a good test. I just bought an F150 Ecoboost and I'm looking for a trailer!!! I'll get them soon!!! Link to comment Share on other sites More sharing options...
mherman2 Posted May 7, 2013 Author Report Share Posted May 7, 2013 Most likely a ring issue. Roger That's what the tech thinks too. He can see cylinder wall damage with the bore scope. I'm just doing everything Ford asks. On simple highway miles during the Shelby Bash before we ever put it on the track it was burning oil and blowing smoke when off the gas at highway speed.

TrakRat Posted May 7, 2013 Report Share Posted May 7, 2013 Anyone install a catch can to see if it's getting sucked out the breather? Link to comment Share on other sites More sharing options...
mherman2 Posted May 9, 2013 Author Report Share Posted May 9, 2013 Ford is sending an engineer our from Michigan to look at the engine. They have been great through this process, couldn't be happier with their support and trying to find the problem. Link to comment Share on other sites More sharing options...
Secondo Posted May 9, 2013 Report Share Posted May 9, 2013 Thanks for the update. I'm interested to see what the solution is. Link to comment Share on other sites More sharing options...

NordicShelby Posted May 10, 2013 Report Share Posted May 10, 2013 Anyone install a catch can to see if it's getting sucked out the breather? YES I have a JLT one and does catch oil but never has it filled the can. I would assume 1/2 inch in the can during 3 hours on the track would be normal.

They have been very responsive and supportive. Link to comment Share on other sites More sharing options...

On simple highway miles during the Shelby Bash before we ever put it on the track it was burning oil and blowing smoke when off the gas at highway speed. Known to do this at cold start up also.

JeffJ Posted May 23, 2013 Report Share Posted May 23, 2013 It will be interesting to see what they finally learn. I would guess from what I see in the racing world, is that most of the oil is being sucked through the intake from the cam covers. These cars pump an amazing amount of oil on the valve train. Under extreme use of the Boss race cars, I've seen a lot of oil in the catch cans from the cam covers. I've seen the Ford engineers at the races working to solve this also with different cam covers, etc. They should put a couple oil catch cans/filters in line of the breather tubes and see what they get on your car. Maybe you can suggest that. Link to comment Share on other sites More sharing options...
08 Ont GT500 Posted May 24, 2013 Report Share Posted May 24, 2013 If it passed the compression and leak down tests it sounds like the rings and valves are good. Kind of curious why the tech would say possibly rings after running and passing these tests. Guides sound more likely letting the oil pass and into the combustion chamber. Hopefully you get things straightened out soon. Link to comment Share on other sites More sharing options...
