I have a slow leak where the water coolant goes to the turbo (banjo connection on the side towards the head).

I seem to remember there are two copper washers on either side of the banjo, can these be replaced with dowty washers ? I have some with nitrile rubber, but not sure they will stand the turbo housing temps...

Either way, do you know what size the washers are, or, FINIS code, so I can get some before getting anything undone ?

Thanks in advance
Greg

 

don't use the dowty washers

the banjo thread size is 18mm

 

The copper washers are cheap enough, or you can reanneal(soften) your old ones by heating to cherry red colour and dropping in OLD engine oil.

Righty-oh, just what I thought regarding the dowty washers. I've ordered a selection of new copper ones in various sizes

Thanks for the help again

Tabetha, agreed they are cheap, but following my experience with copper washers on the fuel pump and filter I try and use dowty ones whenever I can instead
