mackdaddytruckfixer Posted April 4, 2015 Share Posted April 4, 2015 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.

jakebrake86 Posted April 4, 2015 Share Posted April 4, 2015 Sure it's not a 237 and a 5 speed? 1 Quote Jake Link to comment Share on other sites More sharing options...
Green Dash Posted April 4, 2015 Share Posted April 4, 2015 Sure it's not a 237 and a 5 speed?Same engine. 237 was the peak hp @ 1700 rpm and 235 @ the governed speed of 2100 rpm. This is why you will also see both 283 and 285 hp ratings for the 676. 1 Quote Jim Link to comment Share on other sites More sharing options...
raybing Posted April 4, 2015 Author Share Posted April 4, 2015 Well the ad said 7 speed, pic shows one stick Quote Link to comment Share on other sites More sharing options...
j hancock Posted April 4, 2015 Share Posted April 4, 2015 Call the people and ask them to give you the number off the door tag or title. An R685 will be a 237. A 237 5 speed is a super dependable package.Obviously this doesn't guaranty that someone hasn't changed the motor or poorly maintained it. 1 Quote JimIt doesn't cost anything to pay attention.

Green Dash Posted April 4, 2015 Share Posted April 4, 2015 It could be a 7 speed if it has a splitter. Quote Jim Link to comment Share on other sites More sharing options...
