First Time …

Chassis / Longitudinal/transversal beams are surprisingly well preserved. But there are at least 6 rusting-through-holes from the outside into the interior. The vertical profiles which are integrated in the side walls, are strongly rusted at the lower points – there they were (unfortunately) foam filled by the Renault plant. Wheelbases and sills need to be renovated. The braking system must be completely overhauled. The main brake cylinder is missing – someone has cut the brake lines – probably it is the best to make everything new from Kunifern tubes. The replacement main brake cylinder with its pressure differential switch (- i found it as a kit including Mastervac on leboncoin. fr) must be revised. Also a replacement radiator with electric fan must be procured (this goes to my account – I myself have robbed it some years ago for Couchette :-))
The crankshaft is turning, but better to disassemble the oil pan and check the crank bearings / bearing shells plus see if the timing chain and the tensioner are ok. At the rear axle the rebound straps are ripped and the rubber buffers are missing.

Oil Sump

A grey-black gelatinous mass has been deposited in the oil pan.
The bearing bolts and shells look ok for the 137 000 km. The cylinder bore surfaces also look acceptable in the lower area (pistons at top dead centre, with the flashlight),
The crankshaft pins have Ø 46 – so it is still the “old” engine
The 35mm shaft sealing ring in the stearing cover (behind the V-belt pouley) is knuckle hard (literally) and must be replaced

Engine flushing

The two semicircle seals and the flat seal (cork) I have glued with little PU body adhesive, makes it much easier to mount the oild pan. Before rinsing, I drained the old coolant and separated it. For the rinsing afterwards I “handycrafted” an 1. 5mm metal sheet with “Gardena” connection.
