Re: [MBZ] no change after I changed the #4 5 fuel injectors
You had mentioned that those two cylinders had low compression. I've never figured out why changing the injectors would fix low compression. If the theory is that changing the injectors would fix an engine thats got low compression because its carboned up then you'd need several days of hard driving to remove the carbon once the causation factor (in this theory the injectors) was removed. What color is the smoke? I assume you've already eliminated a leaking headgasket as a possible cause? -Curt Date: Wed, 14 Mar 2012 13:08:39 -0400 From: glenn brown g_010...@hotmail.com To: mercedes@okiebenz.com Subject: [MBZ] no change after I changed the #4 5 fuel injectors Message-ID: snt140-w5241a54813fd40a5825f10f0...@phx.gbl Content-Type: text/plain; charset=iso-8859-1 I started and ran my '85 300TD a little while ago and it still has a rough idle and smokes upon a cold startup, but warms up in 2-3 min. and then the idle is as smooth as an old diesel will get and the smoking ceases, so there's no change after I changed the #4 5 fuel injectors yesterday.

Next step? Questions for Glenn. Does the smoke smell like unburnt fuel or coolant? Does it only do this when started from dead cold? (I think you answered in the affirmative before. I work midnights and am brain dead right now.) Questions for list. I've never had the head off of an OM617. Is it possible that the glow plugs are shrouded in carbon and are having no effect? What are the balls in the pre-chamber for? If one was missing, would it cause a problem like this?

Next step? I forget, have you done a cold power balance test by starting the car and cracking open the injector lines one at a time? If so, which cylinders did not cause the engine to run worse when you deactivated their injectors?

Re: [MBZ] no change after I changed the #4 5 fuel injectors
I didn't follow this completely, but didn't you have low compression in 4 5? Its likely if you had bad injectors there, then they've already done their damage and its time for a rebuild. If you suspect heavy carbon build up or stuck rings, drive it and change the oil frequently. If things don't improve after a few thousand miles and several oil changes, you've got some more serious damage. I'm assuming you've already checked valve clearance and confirmed the glow plugs are good. And what lead you do replace only two injectors? Did you have them all tested? Why not replace all of them?
