svigarfarms Posted March 2, 2017 Share Posted March 2, 2017 I was told there is a screen somewhere in the oil supply going to the timing selinoid anyone able to point in the direction of it. We're still having intermittent smoke and rough running Mack scanned it and says timing selinoid is what it says. The blink code is still 6-3. We did replace the timing selinoid and it's no different. Someone told us the 6-3 is actually engine brake output witch makes no sense to me. Any help be appreciated Quote Link to comment https://www.bigmacktrucks.com/topic/48954-e-7-timing-selinoid/ Share on other sites More sharing options...
fullfuel01 Posted March 2, 2017 Share Posted March 2, 2017 check your fuse in the fuse panel. code 6-3 is FIC module normaly. when that fuse blow some truck wont start, some will start and die, some will run ruff as hell. i can't remember wich fuse it is... I assume you have the V-mac1 module for a early 90's to 97 model?

fjh Posted March 2, 2017 Share Posted March 2, 2017 It may be the econovance its self the spring may be broken or simply worn out! If working properly When the engine starts it should stumble and sputter and smoke till the oil preasure comes up then smooth out if its not doing this and u have changed the sol it could be a physical issue with the advance its self! 1 Quote Link to comment https://www.bigmacktrucks.com/topic/48954-e-7-timing-selinoid/#findComment-363094 Share on other sites More sharing options...
