Thanks for all the reply's I put a reman in for 3k this problem is gone

It's a 2002 if that makes any difference. I think they put it in some 2003 models also. I know the 04-06 Macks were junk alot of Turbo issues.

New to this form but an old hand. I have a 90 RD 688 and the front end like it is jumping up and down at 35. I inspected the front end everything looks good. Put new rubber on no change. I hate throwing parts at it without a good idea what I'm looking at. Really I think I should replace rims next. It is a 20k front on 385 floats. Any help would be great. Vibration in steering wheel at 60 +

I have owned E7 and E6 motors my whole life so is there anything wrong with a 2002 Etech ??

Maybe it is time to hunt the used parts market ?

I don't want to high jack your thread but I need some help and I guess this is where the Mack guys are. I have a E6 2 valve that I just had a total overhaul done on less than a 1000 miles on it. I'm seeing water in the oil and oil in the water. Runs real bad when I first start it with some white fuel smoke. Had the heads totally rebuilt also and new injectors. Really it dose run ok after it warms up and is using alot less oil and water but that isn't what I spent $8000 for. And it has a small bit of blow by. Getting alittle milky looking crap under valve pans to. Any help would be great so please help. I'm thinking they rebuilt junk cracked heads that cost me $1200.

I have been loosing A LOT of oil can the compressor blow it into air system ?

no leaks im looking at a reman

I have a 88 R model with a 13 speed Fuller RTOL in it. On the air shift side it will not stay in gear more than 10 seconds. The rest of the trans works well I've been running it in 12th but really need OD on the interstate.

cool let me know how it turns out i have some expr. so i will give you my 2 cents. i myself like the e6 but e9 is my fav

it might be just a simple short in the wire but you would think mack deal would find that but you have to remember people like me have work there lol

I have worked at columbus truck and equipment mack deal rumpkey waste ect 15 yrs at it and the first thing i would do is send the head to be checked or you are wasting your time

they lack in hp I have one and can get u the info you want next week when im home
