Had a bad glow plug, replaced all glow plugs but now the relay light does not come on and can’t start car. Tested continuity from plugs to relay all test good, tested power at the relay seams all good. Not sure where to look now.
There's a seal which is worn behind the catalytic converter and turbo on the back of the block which is causing a rattle. Do I have to remove the turbo to get to it?
It all started after I had run the car up a mountain with curvy roads. I pushed the car a bit (not to hard)after that it started idling rough. Thought it might be injectors leaking. I changed and set injectors. It ran better. Now it has a rough idle and a strong vibration at around 1500 rpm feels like it vibrates the whole car. Also it seems to be have more valve noise when idling, maybe nailing? adjusted valves 2 times.
I replaced the engine shut off vacuum actuator, the car drove for 15 minutes and stalled. I am not getting fuel to the injectors. The question is can the actuator gaskets leak air into the pump and air lock it?
n/a1991 300D.
Starts great. After 30 sec idles rough. Believe the fuel injector is being signalled that the engine is above 60 C when it is not . Where is this temp sensor located.
Hello Kent,
First,I want to say thanks to Mercedes source for the ability to learn everything about these great cars and giving me the know-how to do all my own work. Truly priceless.
hopefully this isn't a double post.
I have apparently 184k miles on a recently bought 300D. It pours out bluish smoke at start up, maybe some whithish mixed in but it's hard to tell.
It bellows out smoke on freeway at full throttle but not really any noticable smoke at constant speed. When i get off the freeway after ~30 miles and idle for a very short time (several seconds) it leaves a smoke trail as seen in rearview mirror and headlights.
I have a 1983 300d with 155k miles on the engine. I have a rough idle issue and no power on take off. slow as a old dog. I have replaced all diesel filters. in tank screen also. I replaced motor mounts and shocks. performed diesel purge, got lil better, but still same issue. Performed valve adjustment, checked cam lobes, ok. performed cold compression test, found 410 to 405 on 1,2,3,4 and 5 cylinders. replaced glow plugs and relay.checked turbo alda, correct and functioning. checked for blockage, found clean and clear. I really dont know what else can be causing this issue. HELP!
I am researching an alternative to the diesel injector hard lines that provide the fuel to the injectors.
I am interested in the nut size and I am looking at flexible hydraulic lines and racing fuel lines.
Does anyone have experience testing alternative fuel lines?
I'm trying to replace the auxiliary pump and I'm having difficulty locating it between the two firewalls.
I removed the battery thinking the pump would be nearby, but all that gets me to is the monovalve. What else do I have to remove to access the pump?
Thank you.
