As title I need to add some stop leak as a temporary measure as the MOT is coming up it says 5% by volume, it does not say in the workshop manuals.

 

If it's wynns stop leak and reconditioner you can safely put the whole bottle in, or is it lecwec ?, at a guess I would say 1.5 litre.

Cheers tabetha, as you can see from the other thread in tech Q&A that you replied to I think that I probably have to take it off and get it checked over, because if the rack support bush is coming loose I think I would need more than some stop leak treatment to cure it, and would probably need a Ambulance if I use it.
