Re: cooler seal Poll

["Herman Haustein" <haustein@netvision.net.il>]

Well that's exactly what I've got! - the green Brazilian type and after
tightening the oil cooler up as much as I dare (and it still leaks) I think
I'll try it with the spacers.
I also had black 8mm>10mms on the old one maybe this is done to solve the
leak ?
On a side note it coud be that someone installed spacers and compressed the
aluminium of the cooler by about 1/2mm or more and now you need spacers.
just a thought
