Re: [MBZ] unburned diesel vapor

If the gasket behind the lift pump went bad, where it mates to the main pump, wouldnt we be seeing engine oil? There is a copper crush under the hand pump that would leak fuel. On Jan 19, 2018 3:07 PM, "Curley McLain via Mercedes" wrote: > That, plus tighten the lift pump, or put a new gasket b

Re: [MBZ] unburned diesel vapor

That, plus tighten the lift pump, or put a new gasket behind it. Since it was recently disturbed, it is the most likely source of the leak. Fred Moir via Mercedes January 19, 2018 at 2:42 PM Max. On an 123 I'd look at the bottom or side plate for seepage. A gen

Yes, o-rings and steel clips vice banjo bolts or hose clamps. However, this car is a 123 wagon with OM617, so probably not the case here. I'm not familiar at all with an '85 wagon, does it have a fuel thermostat / fuel heater like OM601/2/3? - Max Charleston SC On Fri, Jan 19, 2018

Re: [MBZ] unburned diesel vapor

I've forgotten which car this is, but don't the OM606 injection pumps have some fragile fuel line connectors? Mitch. ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://

Re: [MBZ] unburned diesel vapor

It is coming off the bottom of the injection pump somehow, onto the cross member. Leaving little puddles everywhere I park. I will have a closer look this weekend. The lift pump is new but maybe I need to tighten it. On Jan 17, 2018 1:51 PM, "Andrew Strasfogel via Mercedes" < mercedes@okiebenz.com

You need a contest to guess the source, with an appropriate reward. On Wed, Jan 17, 2018 at 4:25 PM, Curt Raymond via Mercedes < mercedes@okiebenz.com> wrote: > Take a couple paper towels and tape them flat over the injectors, the > metal lines and the return lines. Run the engine for a couple mi

Re: [MBZ] unburned diesel vapor

Take a couple paper towels and tape them flat over the injectors, the metal lines and the return lines. Run the engine for a couple minutes, it should help narrow down the issue pretty quick. Are the clamps in place on the metal lines? They'll vibrate and break if not. Thats pretty obvious when

Re: [MBZ] unburned diesel vapor

if raw fuel is smoking, it is almost always time to change the return lines. it is possible for the injector holder to leak, if the seal was reused or not properly torqued. Both will result in fuel surrounding the injector holder, getting hot and smoking off. Meade Dillon via Mercedes

Re: [MBZ] unburned diesel vapor

My first thought is that the return lines from the injectors are failing. Given Randy's caution re: high pressure leak, shut off engine and feel the return lines with naked fingers, smell them afterwards if you can't feel or see fuel on them. Check the cigar hose and other rubber hoses as well. G

Re: [MBZ] unburned diesel vapor

If you think it could be a high pressure line leak, then be very careful looking for it. Do not run your fingers around in there when the motor is running. If you cannot find it, you likely will when it gets a bit worse. RB On 17/01/2018 1:15 PM, Karl Wittnebel via Mercedes wrote: 85 300td i

[MBZ] unburned diesel vapor

85 300td is leaking diesel somewhere, but motor and pump are dry under hood. Have been noticing smell for a week or so. Parking at work today I noticed a vapor coming up out of the left-sided Fender Hood joint which smelled like unburned diesel but looked like smoke. This is the same smell I've be
