leversole Posted January 19, 2013 Share Posted January 19, 2013 I have an E6-350...none of the documentation leads me to know whether I have a 2 valve or 4...is there a way to figure it out?

2stacksuperdog Posted January 19, 2013 Share Posted January 19, 2013 most likely a 4-valve Quote Matt Link to comment https://www.bigmacktrucks.com/topic/29510-4-valve-or-2/#findComment-158339 Share on other sites More sharing options...
jakebrake86 Posted January 19, 2013 Share Posted January 19, 2013 I believe the valve covers on all four valves have an angled top and are aluminum? , while two valve valve covers kind of resemble that of a small block Chevy and are steel. Also, the injector lines on a two valve go up and over the engine between the valve covers to the injectors in the left side of the head, while on a four valve the injectors are on the same side of the engine as the pump. Somebody correct me if I'm wrong. 1 Quote Jake Link to comment https://www.bigmacktrucks.com/topic/29510-4-valve-or-2/#findComment-158341 Share on other sites More sharing options...

I think your right about the valve covers not sure about injectors Quote Matt Link to comment https://www.bigmacktrucks.com/topic/29510-4-valve-or-2/#findComment-158342 Share on other sites More sharing options...
Lmackattack Posted January 19, 2013 Share Posted January 19, 2013 Yea. 2 valve injector can be seen at top of head where the lines connect to it. 4 valve just has the lines entering the side of the head on passenger side. 4v have sloped valve covers. 1989 would be 4 v unless it was pulled and a 2v was swapped in at some point.

jeffbyrne Posted January 19, 2013 Share Posted January 19, 2013 About 87 they went to 4 valve. The rocker covers are a bit like an E9 excepting for three cylinders instead of two Quote Link to comment https://www.bigmacktrucks.com/topic/29510-4-valve-or-2/#findComment-158373 Share on other sites More sharing options...
daveigou Posted January 19, 2013 Share Posted January 19, 2013 In addition to what the others said, if it has chassis mounted charge air cooler, it is 4V, if it doesn't, it's 2V. There may be rare exceptions, like the 1000 series (forerunner of E9) V8. That also was the beginning of the Econodyne (4V & CMCAC) designation.

Vladislav Posted January 19, 2013 Share Posted January 19, 2013 Everything above is true for shue.So you hefinitely have E6-350 4v under the hood.As under mine hood also Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment https://www.bigmacktrucks.com/topic/29510-4-valve-or-2/#findComment-158377 Share on other sites More sharing options...
farmer52 Posted January 19, 2013 Share Posted January 19, 2013 Mack was in the process of converting from 2V to 4V around 1986. Most likely your E6 is a 4V. Post a pic of the engine.

paul roncetti Posted January 20, 2013 Share Posted January 20, 2013 Hi Vlad, i thimk in the context that you wrote it would be "my" also needed to "write", doubt if I ever could learn Russian, you are doing very well.....Paul Quote RONCETTI Link to comment https://www.bigmacktrucks.com/topic/29510-4-valve-or-2/#findComment-158519 Share on other sites More sharing options...
Vladislav Posted January 20, 2013 Share Posted January 20, 2013 Thank you Paul, I think you don't need to learn Russian, English is going to be global. Nobody can learn everything in this world, we have to choose what we like or what we need mostly.
