Drowning and coupling

Hello Transitgemeinde! I have recently called a squeaky transit with simple Womo conversion my own. It is an F100 TAS with short wheelbase and without high roof in 2.5l suction diesel version (I think 68 hp). Equipment is equal to zero, but the condition is very good, because the car has not seen winter since 1995 and in the summer was always driven only for about 2 months (original 140Tkm!). Rust = missing! (except for a few stone strokes, which still have to be treated.) Was a real transit community! The vehicle corresponded to or exactly corresponds to my search grid But as it is, there are also a few things here that disturb me a bit 1. First of all there would be a slight roar between 90 and 100 km/h. Could this possibly be due to hardened engine bearings? Vibrations can only be felt at the switch lever, otherwise it runs very calmly. Or is that normal, since the machine was not developed according to the car standard at the time. 2. I have the feeling that with the Kupplu ng something is not right, because when it is cold sometimes no gear can be laid. That means, if I insert a gear immediately after starting it, it goes without problems. But if I let it run 30sec. in the stand, it doesn’t work anymore. I have to switch to the R-speed (hearable!!!) and then quickly into the 1st gear, that is reasonably possible. Furthermore, the clutch rolls from time to time when starting, no matter whether warm or cold. Since this is my first Ford I know myself with the technology still nic It looks particularly good. I would therefore be very happy about your tips about transit and your help with the above mentioned problems. PS.: He didn’t have a servo…
