Rought starting sometimes and rev issue.
Hello dear D24T.com users!
Well back in november i turned 18 and i got my drivinglicense back in january, so i just had to get a D24 to drive daily haha. well i found a 945 Tdic -95 with manuall transmission (M90!!!!!!!) its either belgien import or NL. anyhow the machine was pretty much an old mans car so no youngsters that have been fixing and trixing with it so all is orginal except 3'' exhaust and a bit more fuel set. not much! anyway, i have a issue where when i rev over 2000rpm the engine "hooks" on the rpm, and directly when i goes under 2000 rpm the rev goes down to idle like i should. another issue is sometimes when its cold outside i can glowplug to times with the automatic system where you turn the key and they turn it off and on agian so i really get "glowplugged" anyhow it starts to go just a little very easy but then when it just stops, like on a petrol engine if you would disconnect all the glowplugs, like the engine doesnt even want to start just a little its all dead, then i glowplug agian and agian and agian and finally it starts... when its warm it start pretty quick, like 0.5-1 sec. sorry for misspelling or bad english, in a bit of a hurry when i wrote this. btw my friend sad that it the "hook" rev problem could be from bad compression in the engine or something, but idk. if needed i will record when i coldstart it in the morning so you can see please help me out, i want to have a reliable daily!

after reading and i have seen some diesel on the pumpside of the engine. I have decided to change the "silicone" cover w/e its called on the back of the pump so no air can leak in. puh hope its that easy and that engine doesnt have bad compression...

the big rubber ring? mad a big difference in starting for me, but I have not had one affect idle control. Eliminating leaks is certainly the first step though.

We're talking about the 17mm IP driveshaft seal? I had one leaker that affected idle. Kept stalling, did not want to idle, but would run at higher RPMs. As this area should be under slight positive pressure when running (there is a weep hole into the seal recess area so fuel can lubricate the seal) it did not make any sense that there could be air ingress there while running. Replacing the leaky seal solved the problem.
Maybe so much air entered the IP overnight that it never completely worked itself out during my testing attempts? As it would die at idle and lower RPMs I did not have the courage to drive it around much because of the driveability problems.

Well its morning here now in sweden and on my way to school. No diesel today, it showed signs of life when i tried starting it, first 1-2seconds then no more diesel getting ignited..., ran out of battery trying to start it, need to get either a new pump or change the seal at the back of the pump, any guide here on the forums how to change the seal since im not really familiar with pumps
