dozerman1 Posted March 2, 2016 Share Posted March 2, 2016 Anyone know what model jake brake I need for a E6 4 valve engine.I have a couple for an E7 4 valve but don't think it will work.Haven't looked at it real close though.

theakerstwo Posted March 2, 2016 Share Posted March 2, 2016 You need a 680A model and yes they are different than a E7 Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/44185-e6-4-valve-jake/#findComment-326218 Share on other sites More sharing options...
Dirtymilkman Posted March 2, 2016 Share Posted March 2, 2016 I was told a early E7 will work on a late E6. I bought a Pacbrake for my E6. Complete kit off of eBay for $650 Quote Link to comment https://www.bigmacktrucks.com/topic/44185-e6-4-valve-jake/#findComment-326228 Share on other sites More sharing options...
theakerstwo Posted March 2, 2016 Share Posted March 2, 2016 Your dealing with two different cam shafts so consider that. Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/44185-e6-4-valve-jake/#findComment-326238 Share on other sites More sharing options...
fjh Posted March 2, 2016 Share Posted March 2, 2016 Glen I was lead to believe That The dynatard Cam would still work on a jaked engine (I could be wrong on this ) How ever the jake model you quoted sounds correct But I beleive the turbo should be to be changed for the jaked engine At least I know there were two gauges to set em 85 thou and 80 thou for diffrent turbos! Had to set by turbo number. Quote Link to comment https://www.bigmacktrucks.com/topic/44185-e6-4-valve-jake/#findComment-326332 Share on other sites More sharing options...

Had to set by turbo number. I like this new forum.fjh I was referring to two cams like a E6 is different than a E7.Yes I had a E6 in the truck that I run now and it had a dynotard then I replaced it with a 680A jake so it will work that way.But I don't know about a 680B on a E6The only thing I would be concerned about is the timing on the E6 to E7.Lift would be I think the same.I have played with the jake on this engine I have now which is a E7 and I don't get much more that a noise.It good to see you on here I have not see you much Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/44185-e6-4-valve-jake/#findComment-326343 Share on other sites More sharing options...
