E 9 -400 RW Mack

[mechohaulic]

I know this E 9-400 topic was recently discussed . went back through the topics  couldn't find. reason for asking is I was looking over a RW with  e9 /400 in it . truck purchased by a friend, trucks good shape  twin screw with sleeper alum wheels /tanks  etc. is there problems 400 is noted for ? I have discussed with owner the BMT site which would benefit him greatly.  apparently he tried but found the questions intense . I explained the log in is to keep the site truck related and not a date site as in the past. left exhaust bank shows oil seepage. which i questioned about idle time .  this truck is a hobby truck ; he's very busy with his own co business and only lets it idle = not happening any longer though.

There was a topic a long while back (10 years or so) with a guy having a E9 and showing oily or tar spot over one of the exhaust ports on one of the heads. Or maybe over a few of them. As I remember the conclusion of the crowd was too long idle could make that effect and the excessive oil (unburned fuel) would go off after some good run.

If no satisfection with such cheer up I would bench test injectors and injection angle and also look for engine oil consumption in some long time frame.

Thank You . positive note it is . based on his comments of letting it idle ; would be indication of manifold oil. unfortunately my knees were in a painful mode ; I didn't dare attempt a climb in cab for starting it.  truck is green which may not be original . I know he was talking of a Magnum ; I didn't write complete vin;;; next trip. 

side note ; received a phone call requesting assistance to get ole #1 R607T = 1001 up and running: and it's in a heated garage . the fun and honor to work on a real truck LOL

not an E9, but a 2001 E7 400.. if i let it idle it would "wet stack" something fierce. 20 minutes would leave the engine covered with oil from either #1 or #2 cylinder( i forget which one) exhaust manifold bolts. if i kicked idle up to over 900 RPM it would no longer wet stack
