My Citroen Gspécial from 1974. Too dark to see the oil drops on the pavement.

“Opération arrêter les fuites d’huile”

Or something like: “stop the environmental disaster of the engine dripping its oil onto the pavement”.

I have started the project to get the engine out of my GS and make it stop leaking oil.

It’s an infamous problem on Citroën’s flat fout air cooled boxer engines in the GS and GSA. The oil return tubes have two o-rings on each side to seal their connection from the cilinder head to the main engine block.

The rubber 0-rings dry out because of their age and the high temperatures of the engine they are part of. And then they stop sealing.

I am also going to check and replace a lot of other parts in and around the engine, because once it is out, you have access. And access is a big issue if you are working on a GS. Seemingly simple repairs or part replacements are awful because of the design of the front end of the car.

I was told that back in the day, GS’s were scrapped because the exhaust had to be replaced. Not because the parts were expensive, but it took a mechanic so much time, the cars weren’t worth the hours and therefore workshop bill (maybe also because of common rust problems with these cars in the rainy Dutch climate).

But the first step in the process was checking the compression on the engine. Just to have an idea about it’s state. I made a small video on it.
