Re: [MBZ] why is my SDL so loud?
I think its probably a trashed engine. Might as well let me take it off your hands. Ill give you $500. On 3/8/07, Kaleb C. Striplin [EMAIL PROTECTED] wrote: Thanks.

[MBZ] why is my SDL so loud?
My current 87 SDL with 230k miles is very loud at idle. Belonged to an old man before I got it and had trap on it. Black smoke alot when I first got it but after trap removed and italian tuneups smokes much less. On cold startup smokes alot and runs rough for a few minutes then is smooth. Cold idle is REALLY loud, warm still too loud. About a loud or louder than a 617. Glow plugs test fine as far as the cold starting goes. Tried everything to get the idle to be quiet like a 603 should be. Ran a can of purge thru the other day and ran quiet while running on the purge but back to loud after a while. Im thinking the injectors need to be replaced but wanted to see what marshall thought, if he is reading this. I guess you could say its nailing but not really, just loud combustion I guess. -- Kaleb C.

Re: [MBZ] why is my SDL so loud?
Mine clatters more than I like after the new head gasket, but it's becoming intermittant, so I suspect it will go away. Otherwise, I got some grit in the lines when I had the head off and may have to replace a nozzle or two. Good luck -- they run s nice when they are working well -- mine is like a new car now, totally smooth, no vibration and no engine noise cruising. I suppose something silly like sealing the exhaust might have something to do with that, though~ Change the oil filter again in 1000 mile or so if the head is crappy looking --- it will be plugged with re-suspended sludge!
