Neal Videan makes them & they work! "My oil consumption has dropped dramatically since I started using Neal's Seals"! Well, a bit of an exaggeration but my engine is much cleaner than it has ever been. Just a satisfied customerI seem to remember seeing an advert for what I think was a rubber/aluminium composite washer to replace copper washerA27.
Can anyone name the supplier?
Thanks
That sounds very much like a dowty washer !
ooops , I meant to say Stat-o-Seal !! These sound the same as you describe above.
